Economists: The Trumps of science

Comment on David Glasner on ‘OMG! The Age of Trump Is upon Us’


You say “The American voters, in their wisdom, have elected a mountebank (OED: “A false pretender to skill or knowledge, a charlatan: a person incurring contempt or ridicule through efforts to acquire something, esp. social distinction or glamour.”), a narcissistic sociopath, as their chief executive and head of state.“

This happened recently in the political realm. In the scientific realm, something similar happened 150+ years ago when Jevons/Walras/Menger took over economics. They made a banana science out of it but people are enthusiastic about it to this very day.#1

David Glasner had his epiphany 50 years ago: “When I took my first economics course almost a half-century ago and read the greatest economics textbook ever written, University Economics by Armen Alchian and William Allen, I was blown away by their ability to show how much sloppy and muddled thinking there was about how markets work ... I have been a fan of free markets ever since.” (See intro)

The trouble with the Alchian/Allen textbook is the same as with all other economics textbooks, that is, it is proto-scientific garbage.#2

The standard definition of the subject matter is given with the following hardcore propositions, a.k.a. axioms: “HC1 economic agents have preferences over outcomes; HC2 agents individually optimize subject to constraints; HC3 agent choice is manifest in interrelated markets; HC4 agents have full relevant knowledge; HC5 observable outcomes are coordinated, and must be discussed with reference to equilibrium states.” (Weintraub)

From these premises follows what Leijonhufvud famously called the Totem of Micro/Macro, that is, SS-curve―DD-curve―equilibrium. This construct is the one-size-fits-all analytical workhorse of economics.

For every person with some scientific instincts, this construct is immediately and forever unacceptable. Economists, to their disgrace, have no scientific instincts at all. They simply swallow every junk hook, line, and sinker. Obviously, the Walrasian axiom set contains THREE NONENTITIES: (i) constrained optimization HC2, (ii) rational expectations HC4, (iii) equilibrium HC5. Every theory/model that contains a nonentity is A PRIORI false. As a consequence, economics from Jevons/Walras/Menger to DSGE/RBC/New Keynesianism is false.

Economists do not know how the actual economy works. They lack the true theory. Instead, they senselessly speculate about NONENTITIES and hallucinate about the marvelous feats of the Invisible Hand.

The worst thing, though, is that economists in their loose talk about markets have not realized to this day that an elementary market system that consists of a consolidated product market and a consolidated labor market is UNSTABLE. This means that, as a matter of principle, there is NO such thing as an overall equilibrium in the market system. The system is NOT self-regulating and self-optimizing, there is NO such thing as an Invisible Hand and this has NOTHING to do with market imperfections or rigidities or information asymmetry. This is a STRUCTURAL feature that is built right into the core of the market system.

It is important to realize that economic policy guidance NEVER has had sound scientific foundations. Because economists never captured the essence of the market economy, whatever they have said for or against capitalism, communism or socialism has been based upon provably false theories about how the monetary economy works.#4

For 150+ years economists are the Trumps of science, that is, "false pretenders to skill or knowledge".
