Hi Jurriaan:

Well, yes, there is something "like" perfect competition - especially at
the level of abstraction where there is profit rate equalization.  But,
the point I was making is that the assumption of something "like" perfect
competition is different from assuming perfect competition.  And, at more
concrete levels of abstraction the explanation of the process of
competition becomes more and more removed from the assumptions underlying
perfect competition.  If, for instance, Marxists used a model of perfect
competition to consider any _actual_ branch of production in the world
capitalist economy then they would be incapable of describing the dynamics
of what happens in those morkets.
