Link Parade: 5.29.15

This is a very old and thoroughly discredited idea, one that dates back to Karl Marx and to the anti-capitalists who preceded him. It is a facet of the belief that free markets are irrational, and that if reason could be imposed on markets — which is to say, if reason could be imposed on free human beings — then enlightened planners could ensure that resources are directed toward their best use. This line of thinking historically has led to concentration camps, gulags, firing squads, purges, and the like, for a few reasons: The first is that free markets are not irrational; they are a reflection of what people actually value at a particular time relative to the other things that they might also value.

People who read Thaler’s list might well just shrug and say, “there isn’t anything here that any good used car salesman doesn’t know.” That’s the point: It’s obvious to anyone who pays any attention at all to himself or his fellow human beings that we are not maximizers, or optimizers, or logical, or even all that sensible. In the early 1970s, when Thaler was a student, his professors didn’t argue that human beings were perfectly rational. They argued that human irrationality didn’t matter, for the purpose of economic theory, because it wasn’t systematic. It could be treated as self-cancelling noise.
