Demand a supply of common sense; just don’t price it

September 20, 2010

“Natural resources originate from the mind, not from the ground, and therefore are not depletable.” Robert Bradley, President, Institute for Energy Research.

Ah, the confusion of economics students when they encounter the subject of supply and demand in introductory “micro.” They learn that prices are determined by supply and demand. Then they’re taught that the quantities supplied and demanded are determined by… prices!

There happens to be no lurking inconsistency here, no magic trick to dazzle us; not even a ridiculous fallacy to accuse the professor of. It’s just a matter of semantics; supply is not the same as “quantity supplied” and demand is not the same as “quantity demanded.” But these semantics do open the door for shenanigans!

The supply (per se) of raw diamonds, for example, is determined primarily by how many diamonds are in the ground and the technology available for mining them. Supply clearly does influence price; diamonds are expensive partly because they are so hard to find and extract. On the other hand, the “quantity supplied” is what is brought to the market by diamond sellers. Price clearly does influence the quantity supplied; the higher the price, the higher the quantity supplied.

So the relationships among supply, price, and quantity supplied are really not so mysterious, at least not until a linguistically reckless or unscrupulous growthman wades in to muddy up the waters. As an example, the late Julian Simon comes to mind, but there are plenty of living counterparts. Robert Bradley, president of the Institute for Energy Research, believes that “Natural resources originate from the mind, not from the ground, and therefore are not depletable. Thus, energy can be best understood as a bottomless pyramid of increasing substitutability and supply.” In other words, innovators supply the world with natural resources, including energy, from their minds. Therefore, the supply of such resources is no problem.

Clearly such a theory induces a healthy supply of corrupt political dialog, in which the word “supply” is, well, over-supplied. I may as well partake!

Consider the number of smokers in a room and the amount of smoke they supply. When we crowd more smokers into the room, we get higher supplies of smoke. As the smoke supply increases, however, non-smokers start to leave. Eventually even the smokers leave, beginning with the lighter smokers who don’t like heavy smoke. So at first, more smokers means a higher supply of smoke, yet eventually a higher supply of smoke means less smokers. In a goofy sort of way, with a touch of linguistic liberty-taking, more smokers means less smokers and cleaner air. (Some of the ex-smokers may have taken up plug tobacco, however, increasing the spittle supply on the sidewalk.) This can be twisted into an insinuation, self-deception, or bald-faced lie that smoking is a self-correcting problem, and that the key to less smoking in society is more smoking!

This ludicrous example mirrors the claim that the invisible hand of the market will “fix” any resource shortages that might arise, which is based on the assumption that increasing price will increase not only the “quantity supplied” but the bona fide supply. After all, supplies come from the mind. It’s smoke-and-mirrors, so to speak.

We’ve all been downwind of cigarette smoke. (Hopefully, few of us have been downstream of plug spittle!) Certainly we have the right to poke a little fun, especially at Big Tobacco’s “Seven Dwarves,” who perjured before a U.S. House of Representatives Subcommittee, “I believe that nicotine is not addictive.” The resulting news broadcast was unforgettable to many Americans, who learned a lot about Big Money that day. We fully expected the Seven Dwarves to announce, as an encore, the Tooth Fairy’s engagement to Santa Claus.

So Americans know quite well how Big Money can pollute the truth. Can we expect the mother of all money-making theories, unlimited growth theory – along with its crazy correlates – to come to us on wings of truth? Sure, sure, higher prices stemming from lowered supplies actually “increase” supplies because they provide an incentive to “supply” even more. And more smoke makes the air “cleaner” by providing an incentive for smokers to increase the “supply” of clean air. More traffic increases the “supply” of open road. More noise actually leads to a greater “supply” of quietness. Less of a good thing leads to more of it! More of a bad thing leads to less of it! Or, if you prefer, less of a good thing leads to less of a bad thing, and more of a bad thing leads to more of a good thing!

So if the growthmen want to claim that oil supplies, for example, are actually increasing, not decreasing, as evidenced by a downturn in price, let them play with the word “supply” like the Seven Dwarves play with “addictive!” Let them use “supply” to mean more, less, an OK mess, anybody’s guess … whatever. But may the rest of us not sound, as one old hand used to say, “Dummer’n a doggone boot!” Supply is how much there is, after all, and as you use it, less remains.

Brian Czech

After years of determined study of ecology, conservation biology, and economics, Brian came to recognize a fatal flaw in our economic framework. The flaw seems obvious, but it is antithetical to economic orthodoxy: there is a fundamental conflict between economic growth and environmental protection (not to mention several other critical societal goals). Not one to sit around and hope for a solution to present itself, Brian took direct action to educate the public on the downsides of economic growth. Working with colleagues in several professional scientific societies, he crafted a scientifically sound position on economic growth that can be signed by individuals and endorsed by organizations. Out of that effort, he established CASSE, which has become the leading organization promoting the transition from unsustainable growth to a steady state economy. Through his crystal clear and entertaining writing, along with his tireless efforts to improve economic understanding and engage others in the cause, Brian has become a leading force for the economic paradigm shift. He is a true hero for sustainability at a time when we badly need one.
