The study of economics has been searching for respectability for many decades. Most recently it has been mathematized in order to make it more sciency and references to the “economic sciences” (sic) abound.
I noticed that today the Nobel Memorial Prize in Economic Sciences had been awarded, and as a lazy news agencies reported it, it was the Nobel Prize for Economics. There is no Nobel Prize for Economics. This prize was named to imply that it is but it is not. They even announce the “winners” at the same time the real Nobel Prizes are awarded to complete the illusion. Pathetic. Almost as bad as the award shows, like the Oscars, et. al. in which an industry rewards itself.
No matter how much respectability grubbing proponents of the study of economics claim it is, economics is not a science. Yes, math can be used, graduate courses in economics now require Calculus where they did not in the recent past, and money can be calculated to fine precision, but the “laws” governing the topic aren’t scientific laws and, in most cases are little better than conjectures.
Take, for example, the concept of market equilibrium. A market is said to be at equilibrium when supply and demand for a good or service balance each other, and as a result prices become stable. If something changes this situation, once breached, the market opposes these changes, moving back in the direction of equilibrium. It is a nice concept and, as a rule of thumb, is a description of a small part of the behaviors one can observe in economic markets. But it is not a scientific law. There are no natural forces behind it. The major users of economics, businesses, are striving fang and claw to create monopolies for their businesses, so that have complete and total control of their market. There is no “market force” or “economic force” that opposes these attempts at “market domination.” Such “economic laws” (sic) are just crude descriptions of how markets can perform under a small set of circumstances.
The whole idea of free markets was built upon the myth of market correction forces. The myth is that politicians should leave markets alone because markets function best when unregulated. This is a baseless, self-serving claim that is not supported by any facts. Those promoting free markets, that is markets free from government regulation, really want governments not interfering with their market manipulations. They want to be the regulator of their markets, not the representative of all of the people, governments.
There is no such thing as a “free” market, which is a good thing because markets do not work without some regulation. Consider pharmaceuticals. Would you want to have a market for pharmaceuticals that was completely free, meaning that anyone could claim anything as an outcome of taking their medicinals and, well, anything goes? No FDA interference? No requirements for effectiveness interference? We have had a glimpse of what this would be like when in 1994, Congress removed “herbal supplements” from the purview of the FDA. What we got were herbal concoctions claimed to cure everything from the common cold to cancer with no requirement that such claims be proven in clinical or any other studies.
An Aside—I have a method of determining when a “herbal supplement” is bogus. If you are temped to try the XYZ herbal supplement, do an Internet search along the lines of “does XYZ really work?” If the first ten websites you find are websites that are bogus, set up by the purveyor of the supplement, you know it is bogus. The practice for such bogus supplements is to put up a dozen or two websites seemingly independently studying your product, but usually just having long lists of testimonials, from people like Tom T. from Philadelphia, or Theresa W. from Portland, Oregon. None of these people can be contacted for verification because not enough information was been supplied, but that would be a waste of your time because they and their commendations are fictional. These website dilute out any honest evaluations of the XYZ supplement.
If you see such sites listed at the top of your search, well, now you know.
Does anyone want “anything goes” markets? I don’t think so. The “free market” bandwagon is just a vehicle to oppose government regulation that protects citizens from phony claims and phony products. Like a dog chasing cars, if it actually caught one it wouldn’t know what to do with it. Any economist who touts the virtues of free markets is a charlatan. Some economists don’t even know they are charlatans. Every course in economics they took in college had the same nonsensical presuppositions built in and then quick raced past to play with more “advanced” topics. Never to the go back and check their original suppositions.
Then they take their suppositions and double down on then, an example of which is Walras’s “law” which says that excess supply in one market must be matched by excess demand in another, so that in the larger picture there will be a general equilibrium. Can any causal connection be made between the demand in one market and the supply in another? I don’t think so. But the concept of “equilibrium” has run away with these person’s common sense. In the physical sciences, a system can only be in a state of equilibrium if it is isolated completely from the rest of the universe, excluding all other matter, energies, forces, etc. As a consequence a system in physical equilibrium is detached from the rest of the universe and has no effect on it or it on the system.
Now, there are systems that are near equilibrium all over the place in nature and those systems show some of the behaviors of equilibrium systems, for one they oppose changes in the distribution of matter and energy in the system, but those near-equilibrium systems are limited in such responses and can always be shoved off of the tracks, so to speak. Economic systems are somewhat like physical near-equilibrium systems but only under very constrained circumstances.
The key point is if you want them to behave as if they were near-equilibrium systems, you would have to regulate the situations they apply to. Certain “market stimulations” would be forbidden, etc. If you want an example of this look at the U.S. stock markets. The “players” in the markets for stocks invent ways to manipulate the markets in their favor on almost a daily basis. The markets, though, are heavily regulated (there are hundreds of pages of regulations adopted by each market) and most of these manipulative practices never get implemented. But every once in a while corrupt players get some control and you end up with high priced worthless “financial instruments” that crash the system, sometimes worldwide, like what happened in 2008. And these morons still preach “regulation is bad!”
I think economists should be required to dress for their profession, witch doctor garb would be appropriate.
The Natural and Other Sciences
Tags: intellectual shuck and jive, the "other" sciences, the natural sciences
Full Disclosure—I was trained as a chemist, so I am by definition a natural scientist. S
The successes of the natural sciences have led other disciplines to adopt the methods and approaches of those sciences for various reasons.
The first scientists were physicists and chemists and a few biologists who built scientific edifices atop the wealth of knowledge collected by various trades. The physicists studying the stars built upon a vast store of knowledge built up by and for mariners. The chemists built upon quite a store of knowledge built up by dyers, embalmers, painters, etc. The botanists started with quite a store of knowledge built up over millennia by ordinary people, especially herbalist “healers.” I say this out of humility. Science wasn’t begun by scientists, it was continued, with methodological advances, from long traditions of studying their topics.
Today we find all kinds of disciplines adopting scientific methodologies; not just using them for support, like archeologists use carbon-14 dating, mind you, but structuring their studies as if they were actual sciences. We have history, psychology, economics, sociology, politics and more all becoming very sciency. And there are benefits to some of those approaches, but not so much so that they could not have been acquired through other techniques.
The difference between the natural sciences and the “others,” is that the natural sciences have a final arbiter of all disputes: nature. None of the others do. Economists talk a lot about “natural experiments,” which are histories of events in which a certain economic concept was engaged. So, they can “test” out their ideas. One example is studies of the impact of raises in the federal or state minimum wage. Some political entity raises its minimum wage, and right nearby another political entity does not. So, what happens? Do people leave the low wage area to get the higher wages? Do business fold under the higher costs of employing their employees? What happens? The problem is establishing cause and effect. The difference in minimum wage is not the only difference between the two regions. (In the “hard sciences” we spend a great deal of effort “isolating variables,” which means establishing what things are changing and which are not. All to establishing that the only things changing are causes and effects.) As a consequence, there is still a major debate, even after numerous studies and “natural experiments,” over what the impact of a change in the minimum wage will be. It also shows that economics is heavily contaminated by politics. Economists with views popular with one group of politicians get mentioned, asked to speak for fees, prestigious chairs at certain universities, and grants to do their “research.” That’s a kind of natural experiment, too.
In the natural sciences, as I say, if you get out of line Mother Nature ups and bitch slaps you back into line. We have a direction for our questions: we ask nature and nature replies. Those replies are not always unambiguous, so some questions get answered wrongly, and corrected (or not) later.
Consider one simple aspect of the theory of evolution. That theory early on claimed that evolution occurred over vast amounts of time. A very prominent scientist, Lord Kelvin, calculated that the Earth, had it started from a ball of molten rock, exposed to a vacuum, would only take around 500 million years to cool to its then state. This was not enough time for the scheme in the theory of evolution to have acted. So, the question was: how old is the Earth and the answer was “not old enough.” Later it was discovered that the Earth contained significant amounts of uranium. When the Earth was molten, the more dense materials sank and the less dense materials floated. The uranium, being very dense sank out of sight and the radioactivity of that uranium accounted for the rather much slower rate of cooling that Lord Kelvin had supposed. So, the age of the Earth is now thought to be 4+ billion years, which is quite long enough for evolution to have done its work. (Oh, and the material that floated to the surface of “Molten Earth?” That scum contained all of the elements needed to make us and the rest of the biosphere. Yes, we are the Scum of the Earth.)
It is clear that economists “scienced” up their field to make it appear to be more substantial than it really is. (If you want details, read Yves Smith’s quite brilliant book, “Econned.”) Many economics majors are now required to pass calculus in their math studies whereas the economists who came before barely used high school algebra. Having “higher standards” to qualify as an economist makes the field seem more prestigious.
Economics papers now are larded with higher math, making them quite opaque to the general public. This is not unlike philosophers retreating from address ordinary people to addressing only other philosophers through the use of complicated (and unnecessary) jargon.
When I was young, there was a field called “Social Studies.” Today we have the “Social Sciences.” Has this made for any outward improvement in those studies? Maybe so, but I haven’t noticed it if it has.
Now, you may take this as one of the “natural scientists” all puffed up about his own importance. Instead please accept the fact that I loathe when my fellow citizens receive a shuck and jive as opposed to honest treatment. Can history or politics be turned into sciences? I doubt it. No matter how hard they try (and I am not including using scientific tools to reinforce timelines, etc.) they have no final arbiter and so they may end up with the trappings of science (Hey, gang, try on these cool lab coats and safety glasses!) but not the substance.
