There are two avenues of criticism that one might take with
respect to neoclassical monopoly theory. In the first place, one
might criticize the purely competitive model which is employed
as a benchmark and as a basis of comparison with monopolistic situations. And secondly, one might criticize the whole concept
of nonlegal barriers to entry, arguing, instead, that it is simply
consumer preference that "limits competition" and that consequently no misallocation of resources occurs.
Most economists would agree that pure competition is not
actually possible. Some would agree, perhaps reluctantly, that it
might not even be desirable or optimal if it
could exist. (If they
agree to this, of course, then they must also agree that moving
toward pure competition is not necessarily desirable, either.) But
few economists have noticed or emphasized the
fundamental flaw of the purely competitive model, namely, that it is not a description of competition at all. Pure competition is a static, equilibrium condition whose very assumptions are such that competitive process is ruled out by definition. Or to put the matter more
charitably, while pure competition may describe the final outcome of a particular competitive situation, the ultimate end
result, it does not describe the competitive
process that produced that particular outcome. The purely competitive theory is
not a theory of competition as such.
The neoclassical habit of confusing competitive process with a
final, static equilibrium condition makes for gross errors in
economic analysis. For instance, product differentiation, advertising, price competition (including price discrimination), and
innovation are rather routinely condemned as "monopolistic"
and, thus, as resource
misallocating and socially undesirable. This
condemnation follows "logically" since not one of these activities
is possible under purely competitive conditions. Hence everything that is truly competitive in the real world, truly rivalrous,
gets labeled as "monopolistic" and resource misallocating in the
Alice-in-Wonderland, purely competitive world. The analytical
conclusions one is forced to come to, employing the purely
competitive perspective, are not just wrong, not just unrealistic,
but the very
opposite of the truth. Far from being able to "predict," or tell us anything meaningful concerning competitive
behavior, pure competition can only describe what things would
be like if the world contained zombie-like consumers with
homogeneous tastes, atomistically structured firms identical in every important respect, with no locational advantages, no advertising, no entrepreneurship, and no rivalry whatever. Surely
this is the major flaw and absurdity inherent in the purely competitive perspective.
