			<content:encoded><![CDATA[<p>It&#8217;s possible that I may have contributed to a few stories not making ink.  If even partially true, it wasn&#8217;t my intention. I believe there was interest in a report Brookings released today: <a href="http://www.brookings.edu/papers/2011/0909_skills_unemployment_rothwell_berube.aspx">Education, Demand, and Unemployment in Metropolitan America</a>.  You can see a <a href="http://news.google.com/news/more?hl=en&amp;gl=us&amp;q=Brookings+workforce&amp;um=1&amp;ie=UTF-8&amp;ncl=dmkkCkr76gKumiMvhP3h5A9DMjVYM&amp;ei=rAlqTvWDG6bY0QHn6rzgBA&amp;sa=X&amp;oi=news_result&amp;ct=more-results&amp;resnum=1&amp;ved=0CDAQqgIwAA">selection of those stories</a> from around the country.</p>
<p>The curious thing was that they had Pittsburgh listed in the top for their categorization of regions listed as &#8220;<a href="http://www.brookings.edu/~/media/Files/rc/papers/2011/0909_skills_unemployment_rothwell/0909_skills_unemployment_summary.pdf">unfavorable Education Match; Favorable Industry Compostion</a>&#8220;.   That group was defined as having an &#8216;overall education gap&#8217; that was a big contributor to local unemloyment.  Basically their point is that Pittsburgh is <em>under</em>educated in its workforce.  Education being the broad taxonomy of high school, college, graduate school; basically years of education.  It was not talking about skills mismatch in very specific occupational categories. These regions are also described as having &#8220;unemployment rates above the national average will tend to persist until they can either boost educational attainment&#8221;.</p>
<p>Problem is that as readers here know, the <a href="http://nullspace2.blogspot.com/2011/06/if-i-was-in-pittsburgh-i-would-have.html">regional unemployment rate is below the national unemployment rate</a> by a lot, and has been for what is now a historical length of time.  As for educational attainment, you can look at parts of the labor force, the younger parts, and conclude we are <a href="http://www.chronicle.pitt.edu/?p=5347">among the most highly educated in the nation</a>.  If you look at the highest levels of education, those with graduate and professional degrees, I think the Pittsburgh region&#8217;s younger workforce is the single most highly educated inthe nation.</p>
<p>So what gives? Educational attainment is typically measured across the entire labor force.  Some standard measures of educational attainment actually look at the population age 25 and over which is even broader.   Our older demographic, coupled with what was a very blue collar labor demand a generation ago means our older generations don&#8217;t quite have the credentialed education of the folks finishing school today.  The younger parts of the workforce is what truly represents how we have been doing as a region in terms of supplying workers.   It&#8217;s not to say the methodology was wrong in the broad report in the news today.   Pittsburgh is an outlier in the scale of change in this sense.  So for most regions it is a decent measure to look at the educational attainment broadly, but for Pittsburgh it misses some very fundamental changes that have taken place in a very recent timeframe.  So the Brookings numbers I am sure are correct, but broadly speaking are reflective of our economic legacy as much as anything else.</p>
<p>If you want to see a really remarkable graph we first put out <a href="http://www.ucsur.pitt.edu/files/peq/peq_2010-03.pdf">here</a>, take a look at the shift over generations in how Pittsburgh compares in this:</p>

<p><span> </span>One  of the reasons that I have always had a problem with Goldman Sachs&#8217;  infamous notion of the BRIC economies was not the fact that it excluded  other important economies such as e.g Chile or Indonesia, but rather  that Brazil, India, Russia and China never belonged in the same group.  The reason for this is largely because of demographics. Both Russia and  China are consequently set to age much more rapidly than India and  Brazil due to very rapid fertility transition in the 1990s. The  demographic situation is especially dire in Russia which not only saw a  dramatic and lingering decline in fertility in the 1990s but also saw a  corresponding increase in mortality (aids and alcohol as big culprits).</p>
<p><span><img src="http://2.bp.blogspot.com/-UIg_CcpW0dc/TdV0RAlqbqI/AAAAAAAABtA/IeBROc-zqkk/s320/picture%2B3.JPG?__SQUARESPACE_CACHEVERSION=1305835562867" alt="" width="257" height="193" /></span></p>
<p>A <a href="http://prbblog.org/index.php/2011/04/22/russian-birth-rate-continues-to-rise/">recent piece by Carl Haub</a> suggests however tha while doom and gloom used to be the prevailing  tone on the state of Russian demographics recent trends suggest that  this should change.</p>
<blockquote><p>Back in 2000, Russia achieved what Russians consider a dubious   milestone, deaths (2,225,300) outnumbered births (1,266,800) by an   astounding 958,500. The crude birth rate had sunk to 8.7 births per   1,000 population. Along with a crude death rate of 15.3, natural   increase hit an all-time low of –6.6 per 1,000, or –0.7 percent rounded   off. The total fertility rate (TFR) bottomed out at 1.195 children per   woman. The crisis, as it was seen to be, was definitely noticed, but   nothing really effective was done until 2007 when Vladimir Putin   announced a baby bonus of the equivalent of $9,000 for second and   further births. Putin has been an outspoken advocate for raising the   birth rate and improving health conditions in order to avoid the   consequences of sustained very low fertility. The program must have   worked since births in 2007 jumped to 1,610,100 from 1,479,600 the   previous year and have rising ever since. This is one of the very few   “success stories” in the industrialized countries’ efforts to raise the   birth rate.</p></blockquote>
<p>Together with the rest of Eastern Europe that was re-joined with the  West after the fall of the Soviet Union, Russia experienced one of the  most brutal fertility transitions ever seen. Indeed, history seems to  have been extraordinarily cruel to many countries in Eastern Europe in  handing them a second chance at the end of the 1980s just to take it  away with the other hand as their demographic fundamentals collapsed.  The birth dearth in the East even stretched into <a href="http://clausvistesen.squarespace.com/alphasources-blog/2009/6/20/germanys-shrinking-east.html">Eastern Germany</a> <a href="http://www.economist.com/node/5637619?story_id=E1_VGPSGTJ">where the</a> <a href="http://www.economist.com/node/5494593?story_id=5494593">total number</a> of live births fell from 215700 to  88300 in the period 1988 to 1992.</p>
<p>I have previously mused that perhaps those multinationals eager to expand eastwards would have to go <a href="http://clausvistesen.squarespace.com/alphasources-blog/2008/4/10/next-stop-kamchatka.html">all the way to Kamchatka</a> to find qualified labour and perhaps even fail entirely and back in  2006, the only silver lining that the Economist&#8217;s Berlin correspondent  could find was how a residing population had led to a revival of  wildlife with the lynx returning to Germany&#8217;s Eastern borders.</p>
<p>Perhaps though, it is time to put this discourse to rest?</p>
<p><strong>Russia in Transition<br />
</strong></p>
<p><span><img src="http://4.bp.blogspot.com/-i8cvgn3L1E4/TdV0Qptq5mI/AAAAAAAABsw/4HPV5Z7HEbY/s320/picture1.JPG?__SQUARESPACE_CACHEVERSION=1305835799788" alt="" /></span></p>
<p>From  1989 to 1999/2001 the total fertility rate in Russia fell from  replacement levels to around 1.1/1.3 and notable effort [1] has been put  into explaining why birth rates fell so much, so quickly.</p>
<p>Grogan (2006) uses a household survey tracking data from 1994 to 2001  and finds that a large part of the decline in fertility among married  couples can be attributed to the decline in household income in the same  period. Grogan (2006) however also sheds light on other aspects of  Russia&#8217;s fertility during the Soviet era. In particular, the paper sets  out to explain completed cohort fertility for women born between 1936  and 1961 and finds that women with higher education had considerably  lower completed cohort fertility rates than their counterparts. This  squares well with the notion of the quantity/quality tradeoff of  fertility famously developed by Gary S Becker [2] and how parents  substitute quantity for quality as their income levels rise (with  education), but it comes with an important twist in the Russian case.  Since female labour force participation was almost universal during the  Soviet era and since women with less than higher education often earned  the same (or more) than their better educated peers, Grogan (2006) seems  to imply an inherent demand, by part of well educated women, for  quality rather than quantity in their fertility decisions.</p>
<p>The other driver of fertility decline in the form of the tempo effect  is also present in Russia, but Grogan (2006) is skeptical as to its  merits in explaining the sharp fall in fertility in the 1990s. It does  appear to coincide with a change in attitude towards marriage and,  specifically, births outside marriage, but from 1988 to 2000, mariage  rates declined for the broad category of women (aged 15-44) as well as  the share of total live births taking place outside marriage rose from  about 14% to 26%.</p>
<p>In essence, the tempo effect over the period in question is not linear and seems to neutralize itself over time.</p>
<p>From 1989 to 1994, the share of births to mothers under 20 actually  rose and then declined to just above 1989 levels in 2000. Not  surprisingly, the share of total non marital live births among mothers  aged less than 20 years rose sharply from 1989 to 2000. This suggests  that the extent to which non-marital live births increased, it resulted  in children being borne to young mothers. From a theoretical  perspective, this is important in relation to how a change in the life  course towards postponing marriage also leads to a postponement of  childrearing. A norm of non-marriage child births may then serve to  weigh against the tempo effect of fertility.</p>
<p>This non-linearity of the tempo effect throughout what was  essentially a sharp linear decline in fertility is interesting. The  charts produced in Grogan (2006, p. 65 fig XI) clearly suggests that  from 1989 to 1994 total live births for young mothers aged under 20 as  well as those from 20-24 rose as share of overall birhts. This reverses  somewhat in 1994 where live births for mothers aged 25-29 starts to  increase as well as those aged 30-34. Yet Grogan (2006) notes that since  there is no meaningful change in the fraction of total live births of  &#8220;older&#8221; mothers in 2000 relative to 1989, the decline in fertility in  Russia is not a postponement phenomenon.</p>
<p>Brainerd (2006) builds on the points above by similarly latching on  to the idea that the economic hardship bestowed on Russian citizens in  the 1990s contributed to the decline in fertility. This suggests again a  more permanent negative quantum effect at work rather than merely a  postponement phenomenon. But the underlying causes of the fertility  decline is cut very finely by Brainerd (2006). Notably, the paper argues  for a pure negative income effect on birth rates and thus a reversal of  the standard quantity-quality tradeoff as developed by Becker. The  interesting thing here is that little evidence is found that general  macroeconomic uncertainty (of the future) affect fertility even if women  with more negative expectations of the future had a higher propensity  of abortion.</p>
<p>Quantitatively, Brainerd (2006) finds strong evidence for how  marriage and a higher income per capita positively affects fertility  using a fixed effect estimation with age specific fertility rates as  dependent variable. Since marriage rates and income declined in the  period 1989 to 1999, it leads to the conclusion that this caused the  decline in fertility. I find this plausible, but would note that the  estimation results suggests that underlying uncertainty of the future  might still be affecting these results. For example, Brainerd (2006)  shows how the effect of income on fertility is strongest for young  mothers which indicates that permanent income may be a more useful proxy  for linking fertility to income levels than the traditional method of  using fluctuations in current income. It also sugggests that the income  effect might be lower over time in the aggregate if we assume a general  process of postponement, but this is dubious in Russia&#8217;s case following  Grogan (2006).</p>

<p style="text-align: center;"><em><span style="font-size: 80%;">And now lets go make some kids &#8230; ?</span></em></p>
<p>In general, the tendency of non-marital births is interesting to  dwell on and Perelli-Harris (2008) [3] draws a sharp distinction between  two reasons to explain it. The first relates to the notion of the  second demographic transition [4] which postulates that the extent to  which non-marital births occur in stabile cohabitations, as e.g. in the  Scandinavian countries, it reflects a change in value towards marriage  and thus a change in the life course. Contrary to this stands evidence,  largely from the US, that non-marital births are associated with much  less stable unions and, generally, poorer levels of society.</p>
<p>Not surprisingly, Perelli-Harris et al (2008) do not ascribe either  of these explanations to the rise of non-marital fertility in Russia,  but rather; a mixture of both. One important aspect here is the extent  to which, after a non-marital contraception, women with higher education  tend to enter into marriage with a much higher probability than women  with lower education. But everyone will be able to find sources to  support their argument with for example <a href="http://www.rand.org/pubs/conf_proceedings/CF124/CF124.chap2.html">this article by Sergei V. Zakharov and Elena I. Ivanova</a> arguing for a more traditional second demographic transition process in Russia.</p>
<p>One overarching conclusion which emerges on the fertility decline in  Russia is that it was not driven primarily by birth postponement but  seems to have been pushed by a more lingering quantum effect. The more  specific driving forces of this quantum effect is much more difficult to  get a hold on, but from the perspective of the macroeconomist it  appears as if Russia entered a sinister spiral of increasing mortality  and declining fertility just as the economy was meant to rebuild and  then later take off on the much hailed wave of convergence. In  particular, it appears as if the general adverse economic environment in  Russia in the 1990s may have caused fertility rates to &#8220;undershoot&#8221;.</p>
<p><strong>Pro-natalism in Russia, Action and Reaction?<br />
</strong></p>
<p>While we may certainly look upon Russia&#8217;s demographic experience as a  frightening example of the effect of negative population momentum, it  would be unfair to say that the Russian leadership has been sitting  idle. In 2006, Vladimir Putin announced a number of pro-natalist  initiatives targeted at reversing the the decline of Russia&#8217;s  population. The plan included longer maternity leave, increased child  benefits and most notably a full USD 9000 payment to women opting to  have a second child Brainerd (2006).</p>
<p>In May 2009, president Medvedev <a href="http://www.telegraph.co.uk/news/worldnews/europe/russia/4279145/Russia-awards-order-of-parental-glory-to-prolific-parents.html">arranged for eigth families to be courted at the Kremlin</a> where they were awarded the Order of Parental Glory; the Levyokin  family chosen to represent the Moscow region had, at the time, given  birth to no less than 6 children.</p>
<p><span> </span></p>
<p style="text-align: center;"><img src="http://2.bp.blogspot.com/-a-O7g0a5Zwg/TdV0Qy_77_I/AAAAAAAABs4/aT8tJokuZb0/s320/picture2.JPG?__SQUARESPACE_CACHEVERSION=1305835719487" alt="" /></p>
<p style="text-align: center;"><em><span style="font-size: 80%;">Getting his Priorities Straight</span></em></p>
<p>The question is whether it has worked?</p>
<p>According to Carl Haub it has (see above), and if this is indeed one  of the few success stories of how  ageing economies can reverse their  birth rate, it is worth paying <a href="http://statsaholic.blogspot.com/2010/05/russian-fertility.html">more than scant attention to</a>.  The data here is subject to some uncertainty, but following Haub&#8217;s lead  the total fertility rate in Russia stood at 1.54 in 2010 which is up  from a low point of 1.2 in 2000. In addition, Haub notes an important  distinction between rural and urban fertility rates with the former  standing at 1.9 in 2010 and the latter at 1.42. This last point is  difficult to underestimate since it shines a rather pessimistic initial  light on the strides to increase fertility in Russia. In particular, it  casts russia in a more classic emerging market context witha a very  abrupt quantity/quality trade-off at work whereby especially urban  fertililty undershoots significantly below the replacement level.</p>
<p>Still, the aggregate picture is improving.</p>
<p><em>(click on charts for better viewing)</em></p>
<p style="text-align: center;"><a href="http://2.bp.blogspot.com/-8yWxdLGUyQA/TdV0ezh7XjI/AAAAAAAABtY/x_etF3K6u-E/s1600/russia%2B-%2Bbreaking%2Bthe%2Bfertility%2Btrap.JPG"><img src="http://2.bp.blogspot.com/-8yWxdLGUyQA/TdV0ezh7XjI/AAAAAAAABtY/x_etF3K6u-E/s320/russia%2B-%2Bbreaking%2Bthe%2Bfertility%2Btrap.JPG?__SQUARESPACE_CACHEVERSION=1305835995436" alt="" /></a></p>
<p>In the jargon of the profession we must now be seriously asking  whether Russia is about to join the very few nations that has managed to  break free of the fertility trap defined here as how total fertility  rates often don&#8217;t recover (or has not recovered yet!) once they fall  below 1.5. The only two other countries which have seen their fertility  levels rebound from below 1.5 are Denmark and France.</p>
<p>I would happily announce that this is the case, but the plot is just about to thicken.</p>
<p>On the positive side and given evidence from the academic literature  that the tempo effect is not a relevant phenomenon in a Russian context,  it stands to reason that this rebound can be interpreted as a real  change in sentiment towards having children.</p>
<p>Score one for Russia&#8217;s pro-natalist policies then?</p>
<p>To some extent though Carl Haub pours water on this idea noting that  the second derivative of the fertility increase is falling which leads  him to ponder whether the rise of Russian births is losing steam. This  argument is taken further by Kumo (2010) [5] who suggests that not only  did Russia&#8217;s pro-natal policies not work in the first place, but also  that the rise in the number of births can be attributed entirely to  fluctuations in the number of women in their reproductive age. More  importantly however, Kumo (2010) emphasizes the difficulties of micro  managing fertility and specifically the issue of just how difficult it  is to get a lasting impact on fertility from cash transfers. In short,  empirical evidence shows that pro-natalist policies rarely have a  permanent effect. This is even more likely to be significant in a  Russian context as the fund set up to dole out money to fertile mothers  expires in 2016.</p>
<p><strong>Ageing in Russia, Adjusting for Mortality<br />
</strong></p>
<p>To assume that the Russian government&#8217;s attempt to push up fertility  rates will have a lasting permanent effect is probably as dubious as  assuming that it will have no effect at all. In addition, if Russia is  serious about securing a future balanced population pyramid, what is to  say that there won&#8217;t be more initiatives?</p>
<p>Still, it appears that just as Russia seem to be making strides in  the fertility department, the appalling situation for adult male  mortality continues to taint the overall picture. Here, the optimists  will call foul play and point out how the main story on Russian  demographics has recently been a <em>co-movement</em> of improving mortality and fertility rates. This may be true, but overall conditions are still poor.</p>
<p>According to data from the World Bank only a mere 47.4% of a male  cohort can expect to celebrate their 65th birthday which contrasts with  78.5% for women. On average (from 1998 to 2009) only 44.5% of a given  male cohort could expect to reach 65 years.</p>

<p>Despite the visible improvement since the mid 2000s, the evidence  from a birds eye view has not changed. Male life expectancy seems to be  mean reverting around 61 to 62 (at birth) and mortality for adult males  exhibits an increasing trend. An afinity to Vodka and other spirits as  well as <a href="http://www.lshtm.ac.uk/centres/ecohost/public_health/premature/">too many cigarettes</a> <a href="http://ideas.repec.org/p/cfr/cefirw/w0128.html">appear to be lingering killers</a>. <a href="http://www.thelancet.com/journals/lancet/article/PIIS0140-6736%2809%2961034-5/abstract">Recent research</a> (2009) from the medicinal sciences using mortality patterns from Tomsk,  Barnaul and Biysk suggests alcohol was a cause of more than half of all  Russian deaths at ages 15-54 years.</p>
<p>As a result, the natural increase is still negative as the up-tick in  births has still not managed to pip the mortality rate here even if it  seems a more lasting change may be underway here.</p>

<p style="text-align: center;"><img src="http://4.bp.blogspot.com/-phkxWrJ8lmA/TdV0RW9DCoI/AAAAAAAABtI/CuXC2Dk-D8o/s320/picture%2B4.JPG?__SQUARESPACE_CACHEVERSION=1305836522394" alt="" /></p>
<p style="text-align: center;"><em><span style="font-size: 80%;">A Rare Sight</span></em></p>
<p>Regardless of the permanency of recent years&#8217; improvement in  fertility Russia cannot escape a rapid process of ageing. More than  anything, this is why I so ardently argue against lumping Russia  together with India and Brazil or more specifically; in Russia there is  no positive demographic dividend in sight; rather what we have is a  negative one.</p>
<p style="text-align: center;"><a href="http://2.bp.blogspot.com/-mUrgUjI9qBo/TdlBZquoM_I/AAAAAAAABuY/cijI925bbWo/s1600/Russia%2Bpop%2Band%2Bdep%2Bratio2.JPG"><span><span><img src="http://2.bp.blogspot.com/-mUrgUjI9qBo/TdlBZquoM_I/AAAAAAAABuY/cijI925bbWo/s320/Russia%2Bpop%2Band%2Bdep%2Bratio2.JPG?__SQUARESPACE_CACHEVERSION=1306083751479" alt="" /></span></span></a></p>
<p>Of course, we cannot simply assume that the Russian population will  fall from here on as one would assume (and hope) that Russia manages to  reverse the trend in mortality. What we can see however is that in terms  of the prime age group (35-54), Russia is likely to have peaked already  in 2004 even if the effect of the double hump is interesting to  consider (a result of assuming a perpetually declining population).</p>
<p><span> </span></p>
<p style="text-align: center;"><a href="http://4.bp.blogspot.com/-ZvBDeuEOT4c/TdV0eryexvI/AAAAAAAABtQ/_0KMnV0W6Tg/s1600/russia%2B3554.JPG"><img src="http://4.bp.blogspot.com/-ZvBDeuEOT4c/TdV0eryexvI/AAAAAAAABtQ/_0KMnV0W6Tg/s320/russia%2B3554.JPG?__SQUARESPACE_CACHEVERSION=1305836624904" alt="" /></a></p>
<p>In addition, the process of ageing means that there is almost no  chance of Russia being able to contribute to global rebalancing by  sustainably running an external deficit. This is one of the single most  important macroeconomic characteristics which suggests why we should not  label Russia as an &#8220;emerging&#8221; economy. Russia and the CEE will instead  be fighting to escape the mantle that they may just have grown old before  they made it to become rich.</p>
<p><span> </span></p>
<p style="text-align: center;"><img src="http://2.bp.blogspot.com/-wAf0RbIARz0/TdV0pwBvxTI/AAAAAAAABt4/DXAd_pBM8Cw/s320/russia%2Bpop%2Bshares.JPG?__SQUARESPACE_CACHEVERSION=1305836655223" alt="" /></p>
<p>Especially the younger part of the labour force will invariably be  subject to a swift decline and the composition of the labour force is  crucial to consumption smoothing on the aggregate level and thus capital  flows.</p>
<p>However, the most important aspect in the context of ageing in Russia  is to adjust for the continuing high mortality rate among men. In <a href="http://www.sciencemag.org/content/329/5997/1287.summary">a recent piece in Sciencemag</a> Warren C. Sanderson and Sergei Scherbov argue that we should rethink  ageing given that as the world population ages so does the threshold at  which we can consider a person (or population) to be &#8220;old&#8221;.</p>
<blockquote><p>(&#8230;) as life expectancies increase and people remain healthy longer,  measures  based solely on fixed chronological ages can                          be misleading. Recently, we published aging  forecasts for all  countries based on new measures that account for  changes in                          longevity (<em>5</em>–<em>8</em>). Here, we add new  forecasts based on disability status. Both types of forecasts exhibit a  slower pace of aging compared                         with the  conventional ones.</p></blockquote>
<p>This makes perfectly good sense and governments around the world are  busy pushing up retirement ages to reflect this, but does this apply in a  Russian context? What good would it do to push up the retirement age in  Russia if less than half of a male cohort makes it to 65? The principle  applied by messieurs Scherbov and Sanderson cuts both ways and in  Russia&#8217;s case we must incorporate an additional accelerant in our  analysis of ageing to account for the continuing high rate of mortality  and indeed an effect which will take some decades to pass through the  pyramid.</p>
<p><strong>Something Stirring in the East? </strong></p>
<p>The recent improvement in Russia&#8217;s demographic indicators begs the  question of whether the glass is half full or half empty. On the former I  would note two things. Firstly, Russia has indeed seen a noticeable  improvement in both fertility and mortality and it seems to have  coincided with the government&#8217;s strategic aim to actually do something  about the country&#8217;s decaying demographics. Secondly, I will salute the  effort in itself. We can all probably agree that Russia has veered a  little too much towards the way of authoritarianism under Putin, but  whatever the underlying ambitions to push forward a positive population  agenda I think it is extraordinarily important.</p>
<p>On the latter however, I am still worried that the trend in mortality  have not been reversed and that, if anything, the situation is  improving all too slowly. I am open to a more positive spin, but the  data and an, admittedly scant, look at the evidence gives little  comfort. As a result, ageing in Russia will be much more acute and its  effect will have a much larger and negative impact than if life  expectancy was a steadily increasing function of time. Indeed, given the  continuing poor state of especially male health in Russia it is  questionable whether the measures above of &#8220;peak growth&#8221; apply at all.</p>
<p>The most important feature of Russia&#8217;s demographic rebound is its  potential permanency and especially we should watch whether Russia  manages to stay above a fertility rate of 1.5. If this turns out to be  case, we could harbour a hope that not only lynxes but also a  rejuvenated Russian population may be stirring in the East.</p>

<p>Can&#8217;t hide from the fact that have long been there already. In fact even in the NYT it has been our story in the the past. See: <a href="http://query.nytimes.com/gst/fullpage.html?res=9506EFDA1030F93BA25756C0A96E9C8B63&amp;pagewanted=1">As Deaths Outpace Births, Cities Adjust</a>.  Here is the trend in births minus deaths, also known as natural population change, in Allegheny County over the last 3 decades:</p>
<div><a href="http://3.bp.blogspot.com/-yhSEJfVf-qg/TcX2O0EUWfI/AAAAAAAABZI/OvdfPo5rTS8/s1600/natchange.JPG"><img src="http://www.citizeneconomists.com/blogs/wp-content/plugins/wp-o-matic/cache/612d4_natchange.JPG" border="0" alt="" width="400" height="265" /></a></div>
<p>So if you focus on population change as a reflection of how people feel about a region, the voting with their feet argument, realize that for us the voting is not quite the same as it is elsewhere else.. and means something awfully different as well.</p>
<p>This is all part and parcel which is what the real big and understudied story that will impact US politics in the next couple of decades. Read from just the other day: <a href="http://www.philly.com/philly/news/nation_world/121231883.html">Census estimates show seniors gaining influence</a> .. and again something we are way ahead of the curve. Read: <a href="http://www.post-gazette.com/pg/06127/688152-103.stm">Older Voters Reign at Polls</a>.  Especially as the Big Sort continues it means primary elections will become ever more important nationally just as they are here.. and it is in primary elections that young voters really shun the process.  Many even register as independents and in closed primaries as Pennsylvania has, can&#8217;t even vote in primaries.  For us, by the time the primary gets here soon, most students will have finished the term and left town further depressing their impact.  Not just the students of course, but a decent chunk of the workforce that is solely associated with education as well.  What if the primary was moved up just a few weeks and the students were still around?</p>

			<content:encoded><![CDATA[<p>The political turmoil in Tunisia and Egypt that precipitated the abrupt end of decades of political dictatorships that governed the vast majority of countires in the MENA (Middle East and North Africa) region. The political revolution, influenced by democratic upheaval in Tunisia and Egypt, facilitated the attempts to overhaul the autocratic regimes in Bahrain, Syria, Yemen and Libya.</p>
<p>One of the most interesting and highlighting puzzles to resolves is which features contributed to the rise of democratic revolutions sweeping across the entire region. In fact, MENA region is world&#8217;s largest exporter of oil, enjoying the largest oil reserves in the world. Saudi Arabia, Qatar, Algeria, Libya and Kuwait constitute more than 42 percent of world oil reserves. In recent decades, MENA region experienced a growing degree of macroeconomic stability with low and stable inflation rate and steady economic growth. Large oil inflows, driven by the growing oil consumption in emerging markets such as China and India, boosted local currency appreciation and current account surpluses. The rates of growth in recent decade were remarkable, reflecting the growth of domestic demand as well as robust investment as the engine of growth. Countries in the MENA region also enjoyed favorable demographic conditions with low old-age dependency ratio and high share of working-age population, resulting in a demographic dividend which brought robust economic growth.</p>
<p>The indices of political change in the MENA countries prior to the outburst of the political protests in Tunisia and Egypt were nearly impossible to predict since a variety of macroeconomic, demographic and structural indicators facilitate the course of political change in developing countries, shifting from authoritarian political leadership towards a democratic political institutions with free press, free election and a vibrant civil society. Prior to the onset of the protests against authoratic governments in the MENA countries, the latter experienced benign levels of economic freedom. In the MENA region, the majority of countries experienced rampant corruption, heavily regulated labor markets, financial underdevelopment and inefficient legal systems. Bahrain, Qatar and Saudi Arabia enjoyed the highest degree of economic freedom in the region while Yemen, Syria and Algeria were already suffering from institutional paralysis and bad governance which brought these countries on the brink of failed states. If political change could be predicted on the basis of the level of overall economic freedom, Yemen, Syria, Algeria and Libya would experience the highest likelihood of political protests that would eventually lead to the political change.</p>
<p>Prior to the independence from France, MENA countries have been plagued by authoritarian governments given the extensive reserves of oil and natural gas. The absence of market institutions based on the rule of law under good governance and independent judicial systems eventually intensifed the rise of hybrid political regimes prone to corruption and poor governance. Even though corrupt military rule and political dicatorship precipitated the rise of the protests against authoratic rule, the pattern of structural change could be easily seen from the changing demographic landscape across the MENA region.</p>
<p>For most of the 20th century, countries in the MENA regions experienced rising income per capita levels. In fact, the growth of per capita incomes in North Africa surpassed the regional average given the fact that North African countries enjoyed high relative levels of income per capita at the beginning of the 20th century compared to Sub-Saharan Africa. For instance, in 1913, Tunisia enjoyed higher per capita income than Mauritius. The change in the demographic structure of the population began after 1950s. In all countries of the MENA region, the fertility rate decreased substantially. In Syria, the fertility rate almost halved between 1950-1955 and 2005-2010, from 7.30 to 3.29. The same trend in the fertility rate swept across the entire region. In Libya, the fertility rate between 2005 and 2010 fell below 3 children per women while Tunisia&#8217;s fertility rate dropped below 2 children per women in the same period. The astounding drop in fertility rates strongly reflected the growth in per capita incomes which boosted domestic consumption of durable and non-durable goods. In addition, oil-exporting countries such as Libya and Bahrain have experienced a substantial increase in export earnings. Large inflow of oil earnings, in fact, unleashed the income effect, brining higher spending on education and infrastructure. The distribution of literacy rates across countries (<a href="http://en.wikipedia.org/wiki/List_of_countries_by_literacy_rate">link</a>) shows that literacy rates in MENA regions are remarkably high. In fact, Bahrain and Turkey boast of 88 percent literacy rate. Libya remained the North African leader in literacy rate (86.8 percent), ahead of Tunisia, Egypt and Algeria which, given the fragmentation and dichotomy of the population, enjoy literacy rates below 80 percent of the total population.</p>
<p>Countries from the MENA region differ substantially in the demographic projections of old-age dependency ratio. The estimates by the UN suggest that by 2030, the dependency ratio in North Africa and the Middle East is expected to experience a persistent rise. In fact, under constant fertility rates, the share of the population 65+ is expected to increase by 25 percentage points in Bahrain, 24 percentage points in Libya, 23 percentage points in Tunisia, 20 percentage points in Algeria, 15 percentage points in Syria and Saudi Arabia and 14 percentage points in Egypt. In Turkey, favorable fertility assumptions predict 7 percentage point increase in old-age dependency ratio until 2030. The empirics behind the clear explanation of fertility dyanmics across the MENA region reveals a persistent shift towards rapidly aging population across the entire region. The expedience of high fertility rates boosts the demographic dividend alongside the growth in income per capita until the break-even point when the pressure of aging population raises public pension expenditure and the introduction of social security schemes. These schemes, in fact, do not pose a systemic threat to the long-term solvency of public pension system as long as high fertility rates boost stationary population growth. The remarkable decrease in the fertility rates in the MENA is partly beared by the increasing amount spent on education. For instance, Tunisia&#8217;s education spending amounted to 7.2 percent of the GDP. The ratio is higher than in many advanced countries in the world. In 2007, Italy spent 4.3 percent of GDP on education, the same ratio as Algeria in the year later. The increasing amount of education expenditure, in both absolute and relative sense, reflects robust literacy rates for middle-income countries of the MENA region. In fact, the increasing amount of education expenditures per inhabitant boosted the information awareness by driving up reading, mathematical and computer literacy. Higher literacy rates, compounded by free access to various Internet applications, could substantiate hypothetically greater awareness of the public demanding political liberties, freedom of assembly and free press.</p>
<p>The demographic transition in the Middle East and North Africa is remarkably uneven, reflecting the variation in income per capita across the region. One of the key drivers of the demographic adjustment is the changing immigration landscape. Traditionally, North African countries have boosted one of the highest outward migration rates, particularly into Italy and France where Muslims account for about 9 percent of the population, the highest share in Western Europe. In addition, with 2.01 children per women, France enjoys one of the highest fertility rates in Europe. A brief overview of the ethnic fertility rates in France shows that French women of the Muslim origin boost significantly higher fertility rates compared to immigrants from Western countries. For instance, the fertility rates for women of Algerian and Moroccan descent exceed the fertility rates of Spanish and Italian immigrants by almost three times. In the next decade, income per capita across the Arab world is expected to increase robustly. Higher incomes would mean a shift towards the increasing amount of expenditures on durable goods. The change in the consumption pattern would be accompanied by a robust decline in the relative amount of income spent on food and other non-durables. Hence, the assumed fertility rates would converge to the Despite the prolonged decline in fertility rates across the Arab world, the demographic transition could precipitate the subsequent decline in robust economic growth rates which exacerbate the rapid rise in per capita incomes in the MENA region.</p>
<p>The peculiar feature of the majority of countries within the MENA region with the exception of Turkey is the presence of natural resource barriers. The abundance of natural resources, such as oil, phosphate and natural gas, is a major constraint on the quality of public sector governance replaced by the seizure of the state by powerful political elites such as the military regime during the Mubarak rule in Egypt prior to the 2011 revolution. Unless accompanied by democratic institutions and systemic constraints on the executive power, the political revolution can eventually result in the organic evolution of the failed state with a strong persistence of the old elites pushing for the status quo to protect the privileges preserved under the old system. The Arab awakening signaled the beginning of the demographic transition with decreasing fertility rates and slowly growing old-age dependency ratios. Hence, diminishing returns to demographic dividend and the gradual relative decline of the share of the working-age population both indicate a tendency towards greater democratic governance.</p>

			<content:encoded><![CDATA[<div>
<p>In a seminal paper [1] from 1958 Franco Modigliani and  Merton H Miller showed why investors should not care about whether firms  were financed with debt or equity. This led to the idea of the the debt  irrelevance proposition and although the DIP is a theoretical benchmark  rather than a real world rule the 1958 paper by Modigliani and Miller  remains a key contribution to the finance literature. We should not  however extend the same role to the recent attempt by researchers [2] to  re-invent the DIP in a new guise replacing &#8220;debt&#8221; by &#8220;demographics&#8221;.  Allow me to explain why.</p>
<p><strong>Demographics, Just Forget About It &#8230;<br />
</strong></p>
<p>My point of departure is Edward Chancellor&#8217;s recent GMO letter in  which he tackles what he considers to be the non-issue of Japan&#8217;s dire  demographics. He emphasizes two things; firstly, that economists are  notoriously poor at predicting demographic variables and secondly he  notes that whatever relevance demographics might have for macroeconomic  analysis at large (of which Mr Chancellor appears skeptical) it is  irrelevant for the investor;</p>
<blockquote><p>Besides, long-term demographic forecasts aren’t particularly relevant  for equity investors. It’s true that changes in the population have a  sizable impact on GDP growth. But stock market returns are not  positively correlated with economic growth. Returns from equities are a  function of valuation and future returns on capital – a subject to which  I will return later – rather than changes in GDP. Nor is there a  positive correlation between population growth and stock market returns.  In short, investors should not get too hung up on inherently unreliable  long-term demographic projections for Japan.</p></blockquote>
<p>It is important to underline, in fairness to Chancellor, that the  points are made with specific focus on Japan but the the argument seems  to have a more general hue. This is even more obvious in relation to one  of Chancellor&#8217;s main references in the form of Morgan Stanley analyst  Alexander Kinmont&#8217;s note entitled <em>The Irrelevance of “Demographics”? </em>Kinmont puts up the following four points which I will use as my points of reference;</p>
<blockquote><p>1. It is not clear that demographic estimates are accurate over long  time frames. In fact, while spurious specificity is one of the  attractions of demographics as a talking point, the fact that neither  death rates nor birth rates have proven predictable should caution one  against accepting any assertion about demographics.</p>
<p>2. It is not clear that demographics are the critical variable in  determining the level of economic growth. That role falls to the growth  rate of TFP.</p>
<p>3. It is not clear that equity returns are related to absolute levels  of growth. Equity returns are an issue of valuation. Nominal returns  are greatly affected by inflation too.</p>
<p>4. It is not clear that demographic change, even if it is allowed as a  negative for economic growth, is necessarily negative for stocks, as  certain forms of demographic change may be associated with a rising  equity market multiple. Demographic change could in fact represent a  benign environment for stocks.</p></blockquote>
<p>On the first point Kinmont makes points to the irony in that the  worry about Japanese demographics seems to be peaking just as Japanese  fertility is on the mend. This is a cheap shot though and not one which  stands up to scrutiny. First of all on the fertility trend itself I get  the same chart as Kinmont&#8217;s below using data from the World Bank showing  a rebound in Japan from a low point of 1.29 in 2003 and 2004 to 1.37 in  2009. However, <a href="http://www.indexmundi.com/japan/total_fertility_rate.html">Indexmundi</a> which takes its data from the CIA World Factbook has fertility much lower and actually declining in Japan. <a href="https://www.cia.gov/library/publications/the-world-factbook/fields/2127.html?countryName=Japan&amp;countryCode=ja&amp;regionCode=eas&amp;#ja">The latest data point from the CIA World Factbook</a> reports an estimate of TFR in 2011 is 1.21. This is a pretty steep  difference and I invite comments as to suggest the right number or at  least the right trend.</p>

<p style="text-align: center;"><img src="http://3.bp.blogspot.com/-_nPhlxfoppE/TaqdJUB9HuI/AAAAAAAABoM/trUtKRCEEXQ/s320/kinmont%2Bjapan%2BTFR.JPG?__SQUARESPACE_CACHEVERSION=1303027056396" alt="" /></p>
<p>All this is of course underlines Kinmont&#8217;s point that we don&#8217;t know  the future and that economists have a proven track record for abysmal  forecast performance. Still, we should get our concepts right at the  offset. Long term projections in <em>age structures</em> are likely to  be robust as they are a function of people already being born and while  migration may change the course of ageing in any given country the fact  that we are all ageing at one at the same time means that there are  fewer migrants to go around. I would then claim that ageing does matter  and that understanding how an economy such as Japan adapts to the ageing  of its population remains one of the most vexing and important issues  for social scientists and investors alike.</p>
<p>So when Kinmont implies that low fertility in Japan is a non-issue I  have to strongly oppose. Just take a look at the chart above Kinmont  himself uses. Fertility has been below replacement levels in  Japan  since 1970 and on current growth rates (assuming a constant growth rate   of fertility which in itself is dubious to the extreme)  fertility  levels would reach replacement levels some time in 2030-40.  So, that  would be 60 years with below replacement fertility. Even if fertility in  Japan (and again in most of the OECD) took a discrete jump to  replacement levels it would do very little to change the outlook for  ageing in the immediate future.</p>
<p>In claiming that demographics do not matter Chancellor are Kinmont  are taking a very wide brush over the general recognition in the  academic literature that our economic systems tend to hit a snag once   fertility falls below a certain level (a TFR of 1.5). This is also   called a <a href="http://demographymatters.blogspot.com/2007/05/fertility-trap-hypothesis-revisited.html">fertility</a> <a href="http://demographymatters.blogspot.com/2006/08/low-fertility-trap.html">trap</a> and what it means is that it becomes very  difficult to escape negative  population dynamics once they set in. I emphasize this since it  highlights that we are not, as a friend of mine likes to point, simply  shooting arrows into the void when we point to the importance of these  issues. I recommend <a href="http://www.oeaw.ac.at/vid/download/pce/dec01/pm/Low_Fertility_Trap_01_12.pdf">the following presentation by Wolfgang Lutz</a> et al and <a href="http://www.oeaw.ac.at/vid/download/edrp_4_05.pdf">the paper</a> that goes with it or <a href="http://fistfulofeuros.net/afoe/the-low-fertility-trap/">this old post at AFOE by Edward</a> if you are still not convinced.</p>
<p>In terms of the postulated increase in Japanese fertility since the  mid 2000 it is a positive development, but as is evident from the data  this rebound is extremely uncertain. In addition, we need to know  whether this is just an echo of the tempo effect (and  thus how large  the rebound is likely to be) or whether it reflects a  real change in  attitudes on quantity. I am open to contributions here but the only  thing we can for certain is that ageing, in Japan and the rest of the  OECD, will continue its march onwards. Here I also feel that Kinmont  puts up a straw man when he invokes the idea of Japan&#8217;s population going  to zero;</p>
<blockquote><p>The unrevealed assumption, then, behind the mathematics used to  arrive at widely-used population estimates is that the Japanese  population will drop to zero. One cannot help but suggest that the logic  of demographic pessimism is circular.</p></blockquote>
<p>I want to re-emphasize that the issue here is <em>not</em> predicting  fertility and death rates but  recognizing the effect that the current  and past trends have on ageing today and tomorrow. Try <a href="http://clausvistesen.squarespace.com/alphasources-blog/2009/7/19/global-population-ageing-what-do-we-know.html">the recent work by Wolfgang Lutz, Warren C. Sanderson, and Sergei Scherbov</a> if you want to see the cutting edge here and while uncertainty is still  a key variable ageing remains a tangible reality. The main question  issue I would like to get across is then that the demographic transition  manifests itself in a transition of ageing and that this essentially  becomes our main unit of analysis.</p>
<p><strong>Growth and Demographics, No Connection? </strong></p>
<p>Kinmont and Chancellor argue that demographics are likely to be less  important for growth over time as total factor productivity (TFP) growth  tends to be the main driver of growth.</p>
<blockquote><p>Japan could quite easily grow at a good rate, especially in per  capita terms, for a high-income developed country even in the face of a  falling population (or more precisely a falling working age population).  All that is required is for TFP growth to accelerate back to the level  of growth enjoyed by Japan prior to the bursting of the Bubble in 1989.  TFP slowdown preceded the population peak. Variation in TFP performance  not in labour input growth is likely to be larger than the negative  effects of population change.</p></blockquote>
<p>This is an important point and more importantly, Kinmont offers an  argument to explain the declining labour input in Japan’s economy which  links in with the fact that Japan has been stuck in deflation and at the  zero lower bound for the best part of two decades (my emphasis).</p>
<blockquote><p>Labour input has in fact fallen at an accelerating pace over the past  20 years. It is clear that the fall is principally a decline in  man-hours. This cannot be simply a function of a decline in the working  age population because that decline only began in 2000. Instead, its  origins must lie in rising unemployment and under-employment. <strong>A  persuasive new paper, The Paradox of Toil, by a researcher at the NY Fed  [3] argues that a decline in labour input is a natural consequence of a  deflationary economy with zero (or effectively zero) interest rates</strong>.</p></blockquote>
<p>In short, the declining labor input in Japan is a function of  deflation and being stuck at the zero lower bound. In addition, this Fed  Researcher Kinmont refers to is Gauti Eggertson who studied under  Krugman at Princeton and did most of his initial work on the liquidity  trap and the zero lower bound. So, I would be careful getting in his way  without a strong look at the argument.</p>
<p>I think however that we might be dealing with the problem of a missing link in the sense that demographics may be one of the <em>primary</em> sources of deflation and the liquidity trap in the first place. This is  an argument that has been pushed in Japan’s case in the sense that it  was a lack of pent up demand that held Japan back in the 1990s as well  as deleveraging. Indeed, Japan may hold a cautionary tale on the effects  of a balance sheet recession in an economy where fertility has been  below the replacement level for an extended period. The Eurozone  periphery (ex Ireland) who have even ceded monetary policy to Frankfurt  are case studies to this theory I think.</p>
<p>I would also emphasize that as labour input declines so does,  obviously, consumption (aggregate demand) input which again feeds into  the the paradox of thrift in the closed economy (or perhaps even a  realisation crisis?). In an open economy it leads to export dependency  as domestic investment actvity responds to foreign demand as well as the  excess income you earn from a positive net foreign asset position (if  you are so lucky as to have one) becomes a crucial source of growth.</p>
<p><span lang="EN-GB">Another more fundamental point is that if the  total factor productivity growth (TFP) is a residual what is actually  hidden in this residual? Well, <a href="http://www.creditwritedowns.com/2010/06/demographics-and-macroeconomics-part-1-wonkish.html">I had a wack at the whole argument</a> a while ago from the perspective of the academic armchair. </span></p>
<blockquote><p>Technology and productivity are famously assumed exogenous in the  Neo-Classical tradition while New Growth theory as it was developed in  the 1980s and 1990s emphasised the need to specifically account for the  evolution of technology. Today, I would venture the claim that there is a  consensus that productivity and technology is a function of what we  could call, broadly, institutional quality which encompass almost  anything imaginable from basic property rights to the level of  entrepreneurship. Indeed, a large part of research is still devoted to  pinning down exactly which determinants that are most important here  both across countries and through time. Now, I would argue that, in the  context of standard growth theory, this is where the scope for the study  of the effect of population dynamics is largest. Thus I don’t think it  is unreasonable to expect the level and evolution of productivity growth  and technological development to be a function of the current  population structure but also its velocity which is a function of e.g.  migration (new inputs?), future working age size etc. Also, this is also  where human capital and the evolution of technology is joined at the  hip through the idea of innovative capacity and readiness.</p></blockquote>
<p>Once we venture into the notion of endogenous growth theory and thus  the attempt to directly explain the sources and components of total  factor productivity growth there is growing evidence that age  structure/demographics alongside a host of other variables are  important. Try <a href="http://clausvistesen.squarespace.com/betasources/2010/10/17/demographic-change-in-models-of-endogenous-economic-growth-a.html">this one</a> for a recent literature review, and for the general link between growth and demographics <a href="http://www.nber.org/papers/w13221">the list</a> <a href="http://www.ecb.int/pub/pdf/scpwps/ecbwp670.pdf">of contributions</a> <a href="http://www.nber.org/papers/w6268">is long</a>. You just need to read around a bit.</p>
<p>I would argue then that growth and prosperity of the modern  capitalist welfare state is highly conditional on some form of  demographic balance and Japan has long since moved beyond into  unbalanced territory. Basically, Japan is stuck in a liquidity trap as  well as a fertility trap. The latter works along the lines of depressing  consumption demand and making it very difficult to maintain key  economic structures such as e.g pension systems. In addition, ageing  affect the growth path of an economy and leads to export dependency,  this last point however which I concede is not yet an established fact  in the literature.</p>
<p><strong>What about stocks then?</strong></p>
<p>We seem to have two intertwined arguments here. Firstly, the extent  to which demographics may have an influence on growth it is irrelevant  for the investor since you can&#8217;t buy GDP growth anyway. Secondly, the  evidence of a correlation between demographics and equity prices is weak  and indeed, if anything, should be bullish for Japan (this last point  is made by Kinmont).</p>
<blockquote><p>Thus the FT summarized the latest findings of the London Business  School team of Dimson, Marsh and Staunton, as published in the Credit  Suisse Global Investment Returns Yearbook, 2010. The LBS academics  examined all the available data (83 markets), and concluded that “99 per  cent of the changes in equity returns could be attributed to factors  other than changes in GDP”. (&#8230;) <strong>Growth is not all that it is cracked up to be</strong>. This analysis underscores previous academic findings showing that growth<br />
per se to be of only small importance to stocks.</p></blockquote>
<p>It would be unwise to disagree with the gist of this point. Even if I  can make a connection between demographics, growth and investor  performance it is very likely that buying into such a story at too high a  valuation will lead to poor returns. Buying at the right value is the  most important aspect of any investment decision.</p>
<p>This however is not the same thing as saying that just as you make  sure to &#8220;buy cheap&#8221; poor demographics, low growth etc are completely  irrelevant. Rather, I think that the extent to which the modern investor  needs to understand a decidedly more complex macro picture with  lingering deflation, heightened risk of sovereign defaults and zero  lower bounds the understanding of demographic dynamics is key. We are  then again discussing the question of deflation and low interest rates  in Japan;</p>
<blockquote><p>The origin of Japan’s problems is falling valuation when compared  with the rest of the world. When we note in addition that it is excesses  of inflation or the arrival of deflation (that is, monetary phenomena  reflecting policy errors) which tend to reduce market average  valuations, we feel it safe to conclude that demography will have next  to nothing to do with the longer-term return profile of the Japanese  market either in nominal or real terms.</p></blockquote>
<p>I feel this is a very dangerous claim to make because it assumes that  the deflation dynamics of Japan and indeed the problems facing the Bank  of Japan in reviving credit growth are unrelated to demographics. In  addition there is the unintended consequence of BOJ having to monetize  an ever greater amount of JGB issuance in the future which in itself  becomes more paramount as Japan ages.</p>
<p>On the second point regarding a direct relationship between  demographics and stock prices (asset prices in general if you will) I  think Kinmont does better especially because he does not fall into the <a href="http://www.investmentmarkets.co.uk/20050317-30.html">asset meltdown hypothesis</a> trap. In short the asset meltdown hypothesis states, in a US context,  that as the baby boomers retire they will dissave and thus need to sell  off their financial assets to a market which cannot support the flow,  because the generation in the working age years is smaller, and that  this will lead to an &#8220;asset meltdown&#8221;. Generalized, this is then the  classic (and naive) nexus between life cycle economics and financial  markets which postulate that dissaving into old age is rapid and  imminent.</p>
<p>There are two problems here. Firstly, the empirical (and indeed  theoretical literature) has found it very difficult to verify that  dissaving occur among elderly cohorts to the extent postulated by the  standard life cycle theory. Secondly, the relationship between asset  prices and broad demographic aggregates appear weak. Results differ from  country to country and most studies take place in a US and Anglo-Saxon  setting which tend to bias the results further.</p>
<p>Kinmont does however point to a study by Geanakoplos, Magill and  Quinzili [4] which show how the ratio of the 45-54 age group to the  25-34 age group is closely related to P/E ratios. As this ratio is set  to increase in Japan, Kinmont ventures the idea that, if anything,  perhaps you would want to buy Japan on the basis of demographics.</p>
<p>I have read the research by Geanakoplos et al and I find it  intriguing, but my problem is that it does not control for the old age  dependency ratio which suggests that the key ratio will be correlated  with ageing in general. But I should be hesitant disregarding it on the  basis of this hunch. I am preparing a large panel data set at the moment  on demographics and stock prices with the aim to essentially rejuvenate  a literature which seems too focused on the asset meltdown hypothesis  noted above.</p>
<p>On a more general level, demographics and investment has been a core  theme in the post crisis flow into emerging markets which, by and large,  share the characteristics of being in the middle or at the end of their  demographic dividend. Again, this does not nullify the importance of  valuation and certainly, the recent soft patch notwithstanding, many  emerging markets are still looking expensive.</p>
<p><strong>Where goes the DIP then? </strong></p>
<p>If you build your story up around the notion that investors buy value  and not GDP growth you can easily come to the conclusion that  demographics are irrelevant for the investor at large. This however  would be a mistake.</p>
<p>I would be the first to wish for a return to a state of affairs in  which investors needed only to look at valuation and firm fundamentals  to make their decisions. Today however, you need to understand the macro  backdrop and in order to do that you need a firm grip on how  demographics affect macroeconomics. Pointing out that we are poor at  predicting birth and death rates as well as pointing to weak evidence  between growth and demographics do not cut it. We need not predict  fertility and mortality but instead we need to understand the effects of  ageing already present and there is plenty of evidence that  demographics affect the growth rate and growth path of the economy.</p>
<p>I am more sympathetic to the strict relationship between stocks and  demographics which is fickle and not well understood. Clearly, there is  not presently any convincing model or framework which suggests how and  why you might be able to buy sound demographics on a beta level. My main  bet is that demographics should, at least, be used to qualify the  notion of the global market portfolio and especially that demographics  be used to re-balance such a portfolio over time.</p>
<p>In conclusion, Kinmont and Chancellor bring up some valid and good  points in their attempt to brush away demographics as an important input  variable to investment and macroeconomic analysis but you shouldn&#8217;t be  fooled. Just as was the case with the original DIP you accept this new  version at your peril.</p>

			<content:encoded><![CDATA[<p>The 2009 PISA test study (<a href="http://www.pisa.oecd.org/pages/0,2987,en_32252351_32235731_1_1_1_1_1,00.html">link</a>) of students&#8217; proficiency in reading, mathematics and science is a highly successful method of evaluating student performance across countries. In fact, the creation of human capital is the main endogenous feature of the long-run economic growth since the quality of schooling and education system are essential to the creation of human capital. The difference in GDP per capita across countries is both intuitive, theoretical and empirical challenge to search for the causes of the gap between the economic performance of nations.</p>
<p>PISA test scores are aimed mainly at the evaluation of student knowledge at primary and secondary level in the fields of reading, mathematics and science. The assessment of knowledge in a particular field is subdivided into six different proficiency levels, ranging from 1 to 6. For instance, students at the 1st reading proficiency level are characterized by innate recognition of simple ideas reinforced in the text while students at the 6th reading proficiency level are characterized by a full capability of making multiple inferences, comparisons and contrasts and integrating the ideas presented in the text into a coherent conceptual framework of abstract ideas, sound evaluation and reflection. While 98.6 percent of OECD students can perform reading tasks at level 1, only 1.1 percent of students across OECD countries can perform reading tasks at the highest proficiency level. In addition, 28.4 percent of students in OECD countries exceeded the 4th (mid-range) reading proficiency level.</p>
<p>The reading scale has been further divided in reading continuous and non-continuous texts. However, the evidence suggest no systematic difference in reading scores between the two fields. Countries with the highest performance, measured as mean score, in reading rank are Korea (89.8 percent), Finland (89.3 percent) and Canada (87.3 percent). Countries with the largest student populations such as United States, United Kingdom and France were ranked in the upper-middle range while percent, and Israel (79 percent), Luxembourg (78.6 percent) and Austria (78.3 percent) are the lowest-ranking high-income countries on the reading scale in the 2009 PISA assessment. In the field of mathematics, 8 percent of students in OECD countries perform below level 1, 31.4 percent of students can perform mathematical tasks at 4th (mid-range) proficiency level while 3.1 percent of students perform at the highest proficiency level. In the country distribution, the percentage of students in the 6th proficiency level is the highest in Korea and Switzerland (8 percent), Japan, Belgium and New Zealand (5 percent). In a regional distribution, more than 25 percent of students in Shanghai perform at the highest level of mathematical proficiency. The proportion of students in the 6th proficiency level is very high in Singapore, Chinese Taipei and Hong Kong &#8211; 15.6 percent, 11.3 percent and 10.8 percent respectively. In addition, performance disparity in mathematics varied significantly across countries. Less than 1 percent of students in Mexico, Chile, Greece and Ireland reached 6th proficiency level A brief overview of the main empirical findings suggests a rather rigorous disparities in country ranking and performance.</p>
<p>The assessment of student performance in science is similar to the distribution of mean scores in the field of mathematics. About 5 percent of students perform below 1st proficiency level. In addition, only 29.4 percent of the students in OECD countries is proficient at 4th (mid-range) proficiency level in science while an average 1.1 percent of students in OECD countries can perform at the highest level of scientific literacy. In addition, the percentage of students below the lowest level of scientific proficiency is highly negatively correlated with country ranking since the proportion of students below the 1st level is the lowest in Finland (8.3 percent), Korea (6.3 percent), Estonia (8.3 percent) and Canada (9.6). Higher country ranking would thus indicate a lower proportion of students below the 1st proficiency level. All of the aforementioned countries ranked in the highest 10 percent of the distribution. If Shanghai, Hong Kong, Macao and Taipei were independent countries, their respective ranking in the field of scientific literacy would be in the top 10 percent of the distribution.</p>
<p>The empirical data on the distribution of mean scores in reading, mathematics and science are highly relevant to the measurement of human capital since the impact of mean scores on economic growth would differ to the certain extent from other measures of human capital. Recent attempts to capture the effect of human capital on economic growth were aimed at the definition of human capital as total years of primary, secondary and tertiary schooling. For instance, Robert Barro and Jong Wha Lee have collected disaggregated data on the total years of schooling for 146 countries between 1950 and 2005 at five-year intervals (<a href="http://www.barrolee.com/">link</a>). The empirical evidence from the country panel suggests a strong linkage between schooling and long-run economic growth and institutional country features (<a href="http://www.voxeu.org/index.php?q=node/5058">link</a>). In addition, Barro and Lee estimated the implicit return from an additional year of schooling ranging from 5 percent to 12 percent.</p>
<p>Gary Becker (<a href="http://www.becker-posner-blog.com/2011/01/implications-of-international-comparisons-of-student-performance-becker.html">link</a>) and Richard Posner (<a href="http://www.becker-posner-blog.com/2011/01/the-pisa-rankings-and-the-role-of-schools-in-student-performance-on-standardized-testsposner.html">link</a>) recently discussed the 2009 PISA findings and the impact of cultural, genetic and demographic disparities on mean test scores in the United States. United States ranked in the middle of the mean score distribution. The rank of the United States (17th out of 79 countries) is above average in reading and average rank in mathematics (31st out of 79 countries) and science (23rd out of 79 countries). As Becker and Posner indicate, the relative performance of the United States should be evaluated with the consideration of cultural and demographic differences since the mean score of White and Asian students is significantly higher than the mean score of African American and Hispanic students. Disparities in mean scores between different demographic groups are typical in largely heterogenous populations. In Belgium, the regional disparity in mean scores between French and Flemish communities is even more striking. While the mean score in mathematics in 2006 in Flemish community had been above the OECD average, the mean score in mathematics of students in French community had been 18.56 points below the OECD average while the mean score of students in Flemish community had been 30 points above the OECD average. In 2009, such a relative difference would place French community in the rank of Italy, Portugal and Spain. On the other hand, student performance in Flemish-speaking community would reach the rank of Canada, Switzerland and Japan.</p>
<p>In the U.S, the demographic disparities in mean scores in reading, mathematics and science do not reflect the quality of the American education system. While the overall quality of the public and private American high school education system raised considerable concerns in previous performance of U.S. students in international mathematics and science ranking, the ranking of U.S. universities in science, mathematics and social sciences is the highest in the world. The output U.S. universities resulted in the highest number of Nobel laureates in physics, chemistry, medicine and economics as well as into cutting-edge accomplishments in R&amp;D and technology. The emphasis on creativity and innovative thinking embodied in the American education system has enabled the United States to emerge as a world leader in technology, R&amp;D, innovation and entrepreneurship.</p>
<p>The openness of the U.S. education system to international students, ideas and creative thinking could account for the remarkable achievements and academic quality of top American universities. On the other hand, poor teacher quality in American high school system is detrimental to the reading and quantitative literacy of American high school graduates, as a consequence of what Becker calls &#8220;teaching-to-the-test&#8221; syndrome where many public school teachers teach students topics not relevant to the command of knowledge but to the tests since test scores presumably determine teacher pay. Eric Hanushek of Hoover Institution recently found (<a href="http://www.nber.org/papers/w16606">link</a>) that replacing bottom 5-8 percent of high school teachers with average teachers could near the United States on top of the international mathematics and science ranking. In addition, the measure is worth $100 trillion according to Hanushek (2010).</p>
<p>In the international perspective, student performance has been viewed as a significant determinant of the difference in cross-country economic performance. Recent paper by Atherton, Appleton and Bleaney (2010) found that higher mean test scores in mathematics, reading and science significantly improve per capita GDP. The authors showed that holding per capita income constant, average years of schooling is less important than mean test scores in predicting the economic growth.</p>
<p>A considerable improvement of primary and secondary education system is vitally essential to the long-run economic growth. International test scores are an important method of evaluating international disparities in student performance and the subsequent impact on economic growth. The evidence from the 2009 PISA study suggests that higher quality of the education system is a necessary condition for higher test scores in reading, mathematics and science.

			<content:encoded><![CDATA[<p>As Millennials (those born between 1981 and 2000) enter the workforce in increasing numbers, it has become clear that the lack of employment opportunities in the job market is impacting this generation more than older generations, which could hold them back for their entire career.</p>
<p>Because an employee&#8217;s raises over the course of his or her career are generally percentage based increases, a lower starting salary will impact the employee for years, as those who start with a higher salary receive increasingly larger raises in dollars because their higher salary and previous higher raises compound the problem over time.</p>
<p>Of course, many Millennials are unable to find a job in their field, or a job of any kind because a combination of the weak labor market and those over 55 continuing to work in record numbers, which forces many new potential employees to find lower paying service jobs or other employment outside of their desired field to meet their financial obligations.  Millennials are also being laid off at a higher rate than older generations, with 14% of them being laid off in 2009 compared to 8% of Baby Boomers, according to a survey by The Futures Company.</p>
<p>This demographic trend will be interesting to watch as Baby Boomers exit the workforce over the next decade, because current long term demographic trends should cause employee shortages in many fields, but will those positions be filled by Millennials who finally get the opportunity they have been waiting for, or by younger employees who would be just entering the job market in the future, leaving Millennials currently in the labor pool permanently under-employed and underpaid?</p>

			<content:encoded><![CDATA[<div>
<p>So, <a href="http://ftalphaville.ft.com/blog/2010/11/28/418271/euimf-irish-bailout-unveiled/">the butcher&#8217;s bill on Ireland</a> is in and stands at 85 billion Euro jointly financed by the EU (the   European Financial Stability Fund (EFSF) and the European Financial   Stability Mechanism), the IMF and bilateral loans from a number of   countries including Sweden, Denmark and the UK. Of course, it only   worked a couple of hours and today markets are reeling again in the face   of the Eurozone crisis which seem to have no end. Worryingly, markets   seem to be contend on going for all together larger game this time   around with <a href="http://ftalphaville.ft.com/blog/2010/11/29/419336/spanish-flu/">Spanish bonds bearing the brunt of the attention</a>.</p>
<p>In principle and fact I agree with RBS&#8217; Harvinder Singh (<a href="http://ftalphaville.ft.com/blog/2010/11/29/419551/the-merkel-crash/">via FT Alphaville&#8217;s Neil Hume</a>)   that the only possible end game at this point is that things get so  bad  that some form of fiscal unity and/or a joint Eurozone pooling of  risk  through the issuance of an EMU bond. Illuminati&#8217;s Jim O&#8217;Neill is a   little more sanguine although he ultimately also invokes the point  that  the core and especially Germany must go all in, in its effort and   comittment to keep the Eurozone in one piece.</p>
<p>I know that all this may come of as scaremongerings, but the farther  we move forward into this mess, the more it is beginning to look like  calm and calculated analysis rather than prophecies of doom.</p>
<p><strong>So, Can Germany Pay?</strong></p>
<p>On that note, I thought that I would highlight an issue which has not  yet  been debated much in the context of the Eurozone debt crisis. In  this sense, we always hear  about CDS or yield spreads to Germany and  still; to the extent that we  are talking &#8220;EU money&#8221; we know that  it is  the German taxpayer who must  foot the majority of the bill.</p>
<p>So, can Germany really pay all this?</p>
<p>The recent economic narrative on Germany suggests that it can. In   fact, Germany has been hailed as the rock onto which all other   shipwrecked European economies must turn to in the hour of need with GDP  growth rates in Q2 and Q3 (2010) exceeding expectations. And with the  German export machine back in full swing, there seems to  be nothing  standing in the way of Germany saving the world, let alone  Europe.</p>
<p>Now, this is not entirely true of course and one major part of the   difficulties encountered in the course of the past months has been the   obvious (and natural) resistance of the German taxpayer in simply   accepting to pay for the mistakes and overspending of others. And one   would assume that the reluctance to do so stems not only from a feeling   of unfairness, but also from a genuine fear that Germany simply won&#8217;t  be  able to pay even if the good intentions can be mustered in the first   place. As such the following point emphasized today by a friend of  mine  is important;</p>
<blockquote><p>Spain’s external debts, have exploded without a significant offset of   external assets. On net, Spain owes the world about 80% (closer to 90%   today) of GDP more than it has external assets. As a frame of  reference,  the degree of net external debt Spain has piled up in a  currency it  cannot print has few historical precedents among  significant countries  and is akin to the level of reparations imposed  on Germany after World  War I. We don’t know of precedents for these  types of external  imbalances being paid back in real terms.</p></blockquote>
<p>So, when Merkel notes that bondholders must also share the losses she   is naturally referring to the fact that Germany cannot be expected to   bailout all the Eurozone&#8217;s periphery&#8217;s international investors.  However,  what she is perhaps forgetting is that Germany itself holds a   non-neglieble amount of those very same net external assets that   Spain, Greece, Ireland and Portugal have built up.</p>
<p>However, even considering this point, the reality is still that as  the  economic conditions of the periphery has deteriorated and morphed  into a  calamity so it seems that the well known structural problems of  the  so-called core have been forgotten. Beauty, wealth and economic  travails are as most other things a  relative entity it seems.</p>
<p>On that note, allow me turn the tables on the discourse a little.   Consequently,  the Economist recently ran a special report on Japan   essentially focusing almost entirely on the fact that Japan is the most   rapidly ageing economy in the world and this represents the main   challenge for Japan as an economy and as a society. I am a demographic  fan boy, I know, but still the analysis in the Economist makes sense.  Deal with the demographic challenge or else &#8230;</p>
<p>So, which economy might then be the second most rapidly ageing economy in the world? Right, you guessed it; Germany.</p>

<p style="text-align: center;"><a href="http://1.bp.blogspot.com/_vhPkPUN2aT8/TPP_tMY7ywI/AAAAAAAABkY/DMQK74mtZ2s/s1600/german%2Bmedian%2Bage.JPG"><img src="http://1.bp.blogspot.com/_vhPkPUN2aT8/TPP_tMY7ywI/AAAAAAAABkY/DMQK74mtZ2s/s320/german%2Bmedian%2Bage.JPG?__SQUARESPACE_CACHEVERSION=1291059250119" alt="" /></a></p>
<p style="text-align: center;"><a href="http://3.bp.blogspot.com/_vhPkPUN2aT8/TPP_sv7PLgI/AAAAAAAABkQ/7c5YjxNWGyM/s1600/german%2Bage%2Bstructure.JPG"><span><span><img src="http://3.bp.blogspot.com/_vhPkPUN2aT8/TPP_sv7PLgI/AAAAAAAABkQ/7c5YjxNWGyM/s320/german%2Bage%2Bstructure.JPG?__SQUARESPACE_CACHEVERSION=1291059309928" alt="" /></span></span></a></p>
<p>I  should think that these charts are rather self-explanatory and  note in this context  that the German debt/GDP has gone from about 63%  of GDP in 2007 to 84%  in 2010. Further, according to the IMF this will  increase to just hy of 90%  in 2014. Naturally, none of these  calculations factor in any extra  liabilities Germany will have to  assume to keep the Eurozone together in  that period, so your guess is  as good as mine as to the final figure in 2015.</p>
<p>The question which seems to whisper in the wind  (and which may  sooner rather than later turn into a roar) is then just how  Germany is  going to be able to shoulder all those bailouts when the real  bailout  it needs to think is the one of its own welfare state as the  weight of  population ageing sets in. Of course, Germany could in  principle  sacrifice any build up of assets in Asia, Latin America and  the rest of  the emerging world and devote its entire surplus powers to  financing  excess investment and consumption in the Eurozone periphery  and Eastern  Europe ad infinitum. But somehow, this does not strike me as  a viable  long term solution since this has already been tried and well,  it got  us into this mess in the first place.</p>
<p>I guess, the  contrarian Masters of the Universe might immediately  see this as a case  for buying German CDS in a punt on the event that  the benchmark itself  came under pressure. I think this would be  premature, but there is  definitely a narrative and discourse missing in  the current Eurozone  debacle not about whether Germany is willing to  pay, but indeed, whether  she will be able too.</p></div>

			<content:encoded><![CDATA[<p>I don&#8217;t suspect anyone remember part 1 of this series so if you want to refresh your memory, you can have a look <a href="http://clausvistesen.squarespace.com/alphasources-blog/2010/6/28/demographics-and-macroeconomics-part-1-wonkish.html">here</a>. In that note, I treated some of the more theoretical issues in the form of how demographics might affect long run growth as well as open economy dynamics. In particular, I discussed the broad tenets of <em>the life cycle framework</em> and how it relates to savings and investment behavior as a function of ageing. In particular, I discussed where I think there was room for improvement and further study.</p>
<p>So, in this one I would that I would look at an all together more practical topic in the form of asset demand and prices as a function of demographics. Again, this is a substantial area in the finance and macroeconomic literature and I will not give a detailed literary review here. Besides, if you want to move straight to investment and portfolio implications this piece by <a href="http://seekingalpha.com/article/228163-global-demographics-trends-and-their-investment-implications?source=dashboard_macro-view">Alicia Damley</a> and this piece by <a href="http://seekingalpha.com/article/236255-india-s-secret-weapon-in-its-economic-race-with-china-demographics?source=dashboard_macro-view">Ed Dolan </a>are really spot on in terms of what you need to think about. Basically, you want to buy the young guns and sell the old farts and the key to obtaining this insight is to remove the focus from population size to population structure (age structure). I have been harping about this since this blog&#8217;s inception 5 years ago, I am doing a PhD about it, so it is with pleasure that I see the discourse hitting the tapes of Seeking Alpha which indicates that it is grabbing hold of other people than those stuck in the university ivory tower.</p>
<p>In this sense, this is hardly a new story . Emerging markets represent <em><strong>the</strong></em> main investment story in a post Lehman context. Everyone wants to buy India, China (although she is quite different), and Brazil and as a result of a myriad of ETFs and other types of market trackers, you don&#8217;t need to know your way around the streets of Bangalore to gain exposure to the Indian growth story.</p>
<p>This is a turkey shoot then. And I largely agree with the main thrust of the argument.</p>
<p>The <em>real</em> maturing of the emerging world which began some 10-12 years ago and which will continue for the next decades is undeniably a force of good for savers and investors and the real question is whether it is too good, and thus whether there will end up being too much capital chasing too little yield. In order to understand this link, you would need the second part of the equation (see part 1) and understand how demographics affect capital flows and the transfer of savings between economies as a function of demographics.</p>
<p>In this note I will talk about the idea of a life course but in the way that it is traditionally narrated. As such, the life course is a sociological theory which describes phases of life and in this sense it is more topical than the idea of a life cycle which only describes the flow of investment and savings. Indeed, in finance and economics you only hear about the life cycle even if scholars who investigate for example the dynamics of house prices as a function of demographics essentially are deploying a life course framework.</p>
<p><strong>What is the Life Course then?</strong></p>
<p>Well, <a href="http://en.wikipedia.org/wiki/Life_course_theory">Wikipedia</a> does a good job of explaining it for the layman and this small snippet also captures the essence quite well especially</p>
<blockquote><p>In particular, it [Life Course Theory] directs attention to the powerful connection between individual lives and the historical and socioeconomic context in which these lives unfold. As a concept, a life course is defined as &#8220;a sequence of socially defined events and roles that the individual enacts over time&#8221; (Giele and Elder 1998, p. 22). These events and roles do not necessarily proceed in a given sequence, but rather constitute the sum total of the person&#8217;s actual experience. Thus the concept of life course implies age-differentiated social phenomena distinct from uniform life-cycle stages and the life span.</p></blockquote>
<p><span>The only mental leap you need to perform here is to replace <em>socially</em> defined events with <em>economically </em>defined events and you have yourself a working model. Now, if the finance geeks out there think that I am turning soft and if the sociologists believe that I am reducing their complicated theory of human lives into numbers and equations, both groups have my symaphaties. </span></p>
<div>
<div><span>Yet, this is a part of my master plan to elevate ageing and the change in age structure to the ultimate unit of analysis on a macroeconomic level. And in order to do this, we need more than merely the life cycle or the life course. We need them both. In fact, only by fusing the two will be able to develop a framework which is rich enough to deal with the complexities of ageing and macroeconomics. Indeed, I am betting a good deal of my academic oevure on this. </span></div>
</div>
<div>
<div><span>Consequently, if a <em>socially</em> defined event of interest to a sociologist or demographer might be the age of marriage, age of first child birth, age of first encounter with alcohol, age of sexual debut etc, then an <em>economically</em> defined event be something along the lines of age of maxmimum borrowing relative to asset value, age of purchase of first home, purchase of durables as a function of age as well as of course, the main topic in the financial literature as it currently stands; portfolio choice as a function of age (stocks and bonds basically, but you can vary the portfolio here as much as you like, at least in principle). </span></div>
<div><span>So, this inclusion of life course into the general thinking of macroeconomics is crucial and even though economists always talk about the life cycle, they are often implicitly assuming a life course perspective. </span></div>
<div><span>In the end, I will keep it short here. </span></div>
<div><span>There is a myriad of sources on aging and asset prices and demand in general. The main man in the world of economics and finance is <a href="http://econ-www.mit.edu/faculty/poterba"><span>James Poterba from MIT</span></a> (just check list of papers) and I would emphasize in particular the strand of literature that deals with <a href="http://clausvistesen.squarespace.com/alphasources-blog/2010/3/26/demographics-housing-and-global-imbalances-wonkish.html">housing and demographics</a> (I have a paper coming here).<br />

			<content:encoded><![CDATA[<p>With the Fed/QE singularity still dominating the markets I thought it would be time for an academic digression  since I am sure you don&#8217;t need me to point you to sources on the current market climate (especially not in earnings spam week).</p>
<p><a href="http://clausvistesen.squarespace.com/betasources/2010/10/17/demographic-change-in-models-of-endogenous-economic-growth-a.html">The one</a> is a real treat and essentially is a literature review of how endogenous growth theory has incorporated the issue of population ageing into growth in the long run. It is written by Klaus Prettner and Alexia Prskawet and is out of the Vienna Institute of Demography which is one of the top 3 (in my opinion) constellations that produce material on the link between demographics and macroeconomics.</p>
<blockquote><p>The purpose of this article is to identify the role of population size,  population growth and population aging in models of endogenous economic  growth. While in exogenous growth models demographic variables are  linked to economic prosperity mainly via the population size, the  structure of the workforce, and the capital intensity of workers,  endogenous growth models and their successors also allow for  interrelationships between demography and technological change. However,  most of the existing literature considers only the interrelationships  based on population size and its growth rate and does not explicitly  account for population aging. The aim of this paper is (a) to review  the role of population size and population growth in the most  commonly used economic growth models (with a focus on endogenous  economic growth models), (b) discuss models that also allow for  population ageing, and (c) sketch out the policy implications of the  most commonly used endogenous growth models and compare them to each  other.</p></blockquote>
<p>As you migth remember I started <a href="http://www.creditwritedowns.com/2010/06/demographics-and-macroeconomics-part-1-wonkish.html">a blog series some time ago on macroeconomics and demographics </a>and in the first post (second is coming soon on demographics and asset prices) I basically laid out some picture points in the context of life cycle theory and demographics. One of these topics included growth which in itself is illusive but also a topic which almost deserves its own label outside traditional macroeconomics since it is a field which is so vast yet pretty strict in methodological terms. The paper by messieurs Prettner and Prskawet is a very good re-cap of the literature (I am definitely going to read 5-6 papers on their ref list) and brings you up to date on how growth theorists model the effect of population ageing on growth in the long run.</p>
<p>The general conclusion is, contrary to the classical Solow model, that population dynamism is positively related to growth or that population ageing is a drag on growth in the illusive steady state. This comes with some qualifiers of course, but as I read the evidence it is pretty much overwhelming from the models we already have. This is an intuitive result, but also a big one in relation to growth theory where the incorporation population ageing has been very long time underway. Moreover, since the contributions who stipulate this are only from the second half of the first decade of the 21st century I think we can call this <em>an advance</em> of no small nature!</p>
<p>So far so good then.</p>
<p>However, apart from the strides made in the context of growth theory I also asked the question of whether steady state growth theory, in general, was suited to explain the phenomena we really would like to explain. Specifically, I said &#8230;</p>
<div>
<blockquote>
<div>The  basic problem here though remains the concept of the steady state which  means that we must construct model such as to allow the change of  capital through time (or its derivative with time) to be 0 in the long  run. Note here that this condition is not imposed on the basis of  empirical behaviour but on the basis of (mathematical) analytical  tractability. So, apart from the uncertainty surrounding exactly what  this ”long run” is, it also locks in the analysis and assumes away a  large part of the important aspects of even basic life cycle behavior.  Specifically, the idea that once reaching a steady state any change in  the savings/consumption rate will one have transitory effect and that  the economy will automatically (and always) converge to the same growth  rate/state as before is a problem. Essentially, the whole idea of a  steady state whether be it in the form of an exogenous or endogenous  growth theory framework is a huge problem since it is evident that such a  thing does not exist. And even if we could establish over a very long  run horizon that such an average/constant path is a good approximation  we would be ironing out all the interesting and important questions in  the process.<span><br />
<a href="http://www.creditwritedowns.com/2010/06/demographics-and-macroeconomics-part-1-wonkish.html#ixzz12pjUmuL5"></a></span></div>
</blockquote>
<div><span>Consider for example the model presented in </span>Gruescu (2007) (see list of references in the paper [1]) and the prediction that growth in the long run is a negative function of a growing dependency ratio. This seems logical and intuitive but this also becomes a problem as Prettner and  Prskawet rightly points out since we can&#8217;t really assume that the dependency ratio <em>grows</em> in the steady state since what happens when it becomes 1 (its natural limit?). As it happens, the idea of a growing dependency ratio in the long run and indeed a growing drag from ageing is exactly the right assumption in most OECD economies. Thus, for all intent and purposes what constitutes the long run for them is equal to a growing share of the elderly in the population.</div>
<div>But the problem is more fundamental since we are reducing a dynamic and path dependent parameter (ageing) to a growing constant in steady state in which growth itself is constant as a function of a some form of technological growth rate (in this case exogenous, but it need not be). Indeed, I think it fair to say that this is an <em>onthological issue</em> that we have not yet adequately addressed or which has not yet been duly formulated. My point is simple; in order for something to be important in the steady state, it must be exhibit a constant and stable growth rate. Demographics and the effect it exerts on economic processes are neither constant nor stable (although again, the idea of a constantly growing dependency ratio is not that far fetched).</div>
<div>But I digress.</div>
<div>The frontline in growth theory has come a long way in explaining the association between long run growth and demographics and while, as the authors point, out much depends on the modelling framework and thus the underlying assumptions on how relevant inputs to growth are created and transformed into output I think (and hope) that empirical observation and falsification will determine which frameworks that end up as the best models to explain growth.</div>
<div>One thing is sure, the paper by Prettner and  Prskawet is a great tour of the most important models and their implications. If you are doing any kind of work on this, you want to read it.</div>
<div>&#8212;</div>
