Paul Krugman demonstrates his irrelevance yet again:
What was Mr. Rubio’s complaint about science teaching? That it might undermine children’s faith in what their parents told them to believe. And right there you have the modern G.O.P.’s attitude, not just toward biology, but toward everything: If evidence seems to contradict faith, suppress the evidence.
No, Rubio apparently believes that parents—not the state—should determine what their children are to be taught. Now, the logical way to go about this is to homeschool your kids. However, I can’t think of a single good reason why state-run schools in a democracy educate citizens’ children according to the desires of the citizens.
Anyhow, Rubio’s complaint is not that science contradicts children’s faith; his complaint was that public education was teaching things contrary to the desires of the parents. Since parents are citizens in a representative democracy and also pay taxes, it is right for the government that claims to represent the parents to obey the wishes of the parents when educating their children. To put it in terms that hopefully even a statist clown like Krugman can understand, Rubio apparently believes that children belong to their parents and not the state.
The most obvious example other than evolution is man-made climate change. As the evidence for a warming planet becomes ever stronger — and ever scarier — the G.O.P. has buried deeper into denial, into assertions that the whole thing is a hoax concocted by a vast conspiracy of scientists. And this denial has been accompanied by frantic efforts to silence and punish anyone reporting the inconvenient facts.
How soon we forget East Anglia. Now, when even the head scientists at the East Anglia Institute itself admit that the data is faked, fraudulent, and highly massaged manipulated, then perhaps we can conclude that the data is not trustworthy. And since a goodly amount of working papers and policies are actually predicated on data released by the East Anglia Institute, then it is quite fair for most, if not all people to be somewhat skeptical or even highly skeptical of the case for man-made climate change.
Furthermore, since there has been little research on how the sun—you know, that big ball of fire in the sky that only heats the entire world every day—impact long-term global temperatures, then perhaps all of us would be justified in being a little more skeptical of anthropogenic global warming.
We are, after all, living in an era when science plays a crucial economic role. How are we going to search effectively for natural resources if schools trying to teach modern geology must give equal time to claims that the world is only 6.000 years old? How are we going to stay competitive in biotechnology if biology classes avoid any material that might offend creationists?
I don’t know, division of labor?
Both my parents are public school teachers. You know what they don’t teach to fourth-graders in public school? How to search effectively for natural resources. Know why? Because that subject is not something that most fourth-graders are able to grasp.
I attended public school for my last two years of high school. Know how many biotech classes my school offered? Zero. Know why? Most high school kids don’t have the intellectual chops for biotech. For crying out loud, most college kids don’t either. Come to think of it, a good number of adults probably can’t wrap their heads around it.
Now, maybe Krugman should retake Econ 101 and read up on the division of labor. This is a fairly well-established concept, having been around since at least 1776 (in Smith’s The Wealth of Nations), that states that production can become more efficient when labor is divided up into various roles and sectors. Not everyone is going to take a job searching for natural resources, nor is everyone going to take a job in biotech. Those who do go into those industries will likely require some training beyond mere public school. Thus, it makes little sense to complain how creationism will take away from future biotechnicians’ budding careers, since most kids won’t need those classes, and those that do won’t need them until college.
Frankly, Krugman has turned into a caricature of his former self. I don’t know what happened to him, but his critical thinking skills—not much to brag about in the first place—have just gone down the toilet. Does he have Alzheimer’s or something? If so, I think it’s pretty safe to say that his mind is about gone, so maybe the New York Times might to go ahead and let him go already.
Some people would rather rub a raw onion in their eye then try to understand economics. That is unfortunate because the basics of economics are not that hard to understand. The fact is that you and I and everyone else use economics every day of our lives. It is liberating to understand why economic things happen, in the same way that it is liberating to know why a car takes longer to stop on ice or gravel. The essence of politics is the use of economic law to manipulate the behavior of citizens to the will of the politicians. Political motivations become more understandable in that light, though no more moral or justified.
Economics is merely an attempt at understanding the basic laws that work in our lives. It seeks to define and simplify our knowledge of the forces that affect us so we can make appropriate decisions. We similarly use the physical principles of gravity, momentum and force every day of our lives. In both economics and physical sciences, there are relatively few laws, which can be applied in understanding very complex systems. Unfortunately, many modern economists actually add confusion and complexity by repudiating simple economic laws, substituting complex macro-economic theories, mathematical models and personal policy preferences.
With that said, the basic laws of economics are truly straight forward and powerful, and arise from the way that humans act and make decisions. Because the logic of human choice hasn’t changed, the economic laws that governed ancient societies are the same ones that govern our lives today, as well as all future civilizations of any time. We can relate to historical characters from any place on the globe because they acted like we do. Their wisdom and their follies are reflected in our experiences today. All that has changed over time is the technology we use to satisfy our needs and wants.
One of the key concepts in economics is that incentives matter. Humans take specific actions to achieve specific goals. If the incentives change, it will affect the means and the ends chosen by the actors. Related to this is the idea that choices are made at the margin. The law of diminishing marginal utility implies that the higher the quantity of a good a person has, the lower the marginal utility, or value, the next available unit holds for that person. If you are dying of thirst in a desert, you would pay almost any price for the first cup of water. You wouldn’t value the fifth cup nearly as much because your thirst would be quenched. You would value the 1000th cup of water much less because you can’t carry it and it does you little good. It’s marginal utility is very small.
The fact that the current market price for a good is $1 doesn’t mean that everyone is willing to pay a dollar. Some people would have a higher marginal utility and be willing to pay more, while others wouldn’t buy it unless it was cheaper. It only means that, at that price, the number of buyers at the margin, those willing to pay at least $1, are about equal to the number of sellers at the margin, those willing to supply it for $1 or less.
This is typically stated as economic laws of supply and demand. If the price of a specific good is lowered, buyers will be enticed to purchase more. We see this in every day life as retailers so often use discounts and sales to move inventory. If the price is raised, the quantity demanded will be less. On the other side of the coin, suppliers are in business to make profits. It will be difficult to make a profit if prices are too low, and very little will be supplied. As prices increase, it becomes easier to earn money, thus suppliers produce more, and new competitors are drawn to the market. Supply increases with increasing prices.
The incentives for buyers and sellers are at odds, and for every good in a particular market at a point in time, there will be a price where the number of willing buyers about equals the number of willing sellers. Any price above that point will produce an excess of sellers, a glut of goods. Any price below it will produce an excess of buyers, a shortage of goods. That simple relationship is one of the most powerful keys to understanding economic phenomena, whether it is Hurricane Katrina shortages or gluts of labor, more commonly called unemployment. Prices, demand and supply are all mutually dependent and reflect the market environment at a particular time. Imposing an artificial limitation on any of them will have inevitable unintended consequences, often very powerfully.
With this understanding, it is possible to comprehend the bulk of the phenomena occurring in society, and in politics, on a day to day basis. There is a lot more to it, of course. A very important aspect of economic laws and concepts from an overall point of view is that they can help to understand why an economy progresses or regresses over time.
The laws of comparative advantage and division of labor are related and work together in determining the level of productivity and prosperity of an economy. Comparative advantage means that any person, organization or geographic region has specific advantages, whether that is because of natural resources, innate skill, education and any number of other characteristics. If the actors concentrate on those things that they are most productive at and pay other people to do the things they less productive at, everyone will be better off overall. A typical example may be an attorney who may have better secretarial skills than any secretary available. But since attorney’s make a much higher hourly rate than secretaries, the attorney will be better off by doing attorney work than secretarial work. The secretary likewise would probably be better off leaving attorney work to the attorney and concentrating on the areas where relative skills are the highest.
Division of labor is the recognition that everybody has only 24 hours a day. It takes a great deal of time and effort and the right tools to be highly productive in any endeavor. Nobody cannot develop all of the skills and purchase all of the tools needed to be highly productive at all types of activities. People or geographic regions that try to be self sufficient will lead a very poor, difficult life and work very long hours.
A surgeon may be very good with his hands, but will probably hire someone to do his plumbing, carpentry, auto repair and so on. He could probably develop some low level of competence in each of those areas, but in order to do that, he would probably sacrifice very valuable time at which he is most productive. In an advanced society, there is a strong tendency toward specialization because it leads to higher productivity and a higher standard of living.
Because people who specialize are generally more productive, they have more income with which to buy the goods and services of other people. Most people in modern society outsource most of their requirements to other people or businesses. They outsource their food requirements to grocery stores and farmers. They outsource their automobile needs to car manufactures. They outsource their homebuilding needs to experienced carpenters, and so on. By building a high level of competence in one area, you are able to trade with others for the things for which they have built a high level of competence. That is what trade is all about. We outsource our requirements to others who are more highly qualified in those areas, and thus, both sides reap the benefit.
If you define progress in society as that state of affairs where people have to work less hard for less hours in order to provided for themselves and their families, then the higher the level of division of labor and the more people can apply their comparative advantage, the more quickly they will progress to a higher level. The wealth of a society comes from people producing more than they consume. Over time, that wealth can be used for capital investments that enhance the productivity of participants, and thus, further raise their income and standard of living. Societies that restrict trade and inhibit capital accumulation and specialization are those that remain in perennial status of less developed countries.
The laws of economics hold many important lessons on a day to day basis. You can try to disobey them, but it is similar to disobeying the law of gravity. You can step off a tall building and think you won’t fall, but your funeral will be just as sure as if you realized you would fall and die. The most critical lesson that economics can give is that actions have consequences. Good intentions and powerful politicians don’t make a bit of difference. The more we can gauge the true consequences without sentimentality or blinders, the more likely we are to make decisions which avoid the pitfalls and lead us to our goals, as individuals and as a society.
I really hate shoveling snow. I live on a large corner lot with lots of sidewalk, so the job can take me over an hour. Snowblowers, I’ve found, are overrated. I’ve had two and neither did a very good job and both had maintenance issues. I bought both used, so that might be part of the problem, but when faced with buying a new one (after my 2005 model died this past week), I thought about how much I hated dealing with the snow and questioned the economics of hiring someone to do the shoveling for me.
It’s a little embarrassing. I’m thirty and work from home. I guess I could be considered “lazy” for not doing my own snow removal, but I prefer to think of myself as an ardent believer in the economic concepts of comparative advantage and the division of labor . So I went on Craig’s List and posted a job for “Regular Snow Removal, Good Pay” with all the details. Since there was only one local posting offering snow-removal service, I didn’t know if I’d get a response… But I didn’t have to wait long to find out.
Almost instantly, I got two emails. By the time I woke up the next day, I had ten. By the end of the second day, more than twenty. Two people stopped by my house to introduce themselves. And after about eight inches of snow rained down last night, a third young man showed up, unannounced, to take care of it for me.
I paid him $40 and he did a great job. Was this worth it? Well, consider this: as a freelance writer, I typically earn between $25 and $50 an hour. My average is probably around $40. So, assuming I can find an extra hour of work to do, I just have to think of it this way: would I rather spend an extra hour writing or shoveling snow? It’s an easy decision for me to make. In fact, even if I earned only $20 or even $10 an hour, I still think it’d be worth it — that’s how much I hate dealing with the snow.
The exuberant responses I’ve gotten from people wanting to shovel my sidewalk and driveway have me thinking of other ways I can kill two birds with one stone: help people who are out of work and lessen the number of unpleasant tasks I have to perform. I’m thinking of hiring someone to do my family’s laundry, for example. It’s the type of thing that always seems to get only half done (i.e., all of my clean clothes are still in the basement, not hung up in my closet) for one reason or another. Perhaps picking up an extra hour or two of writing work (which I enjoy) could save me and my wife from having to do the laundry (a constant source of marital strife) and help someone put food on the table too. Capitalism is win-win.
