There are hardly any (mainstream) economist that will disagree with the claim that perfectly competitive markets lead to the most efficient outcomes. These markets should have no barriers to entry, nor be dominated by any agent or group of agents.

Mainstream economists are also eager to encroach on other fields of study, especially to do the other “lesser” social sciences better than the other social scientists. It would seem, then, only appropriate that they should eagerly apply their ideas to the study of knowledge. A neoclassical perspective on knowledge encourages what many have called a “marketplace of ideas.” This marketplace should have an abundance of competing hypothesis, all critically examined, to produce the best knowledge for our society. And there should be no dominant practitioners, who might exert excessive market power and find us in an inefficient market (of knowledge). Inefficient knowledge would mean that we would not have the best science possible.

But in the current state of economics, there are enormous barriers to entry and the “marketplace of ideas” is hardly competitive. Neoclassical practitioners keep the gate of the profession by controlling the economics departments at the top research universities and the “top” economic journals. Mainstream economists do not take any competing hypothesis critically because they do not even understand the basic ideas of any heterodox economic program, nor do they care to.

This exclusory attitude towards competing hypothesis is contradictory to the tenets of neoclassical economic theory.  Any hypothesis that competes with neoclassical economic theory is dismissed as “not economics.” It should then come as no surprise, even the logical conclusion, to the neoclassical economist that the current market for economic knowledge is inefficient. And our society cannot possibly have the best economic science. We can do better.
