Begging the inequality question, by Chris Dillow: ... many of us dislike inequality not because we envy the mega-rich but because it is (sometimes) a symptom of malfunctioning markets... The fact that so many bosses get paid millions even for failure suggests that they are not paid their marginal product. Instead, some mix of agency failure, efficient wage considerations (bosses must be paid not to steal corporate assets) and arms races force pay above marginal product.
Sure, you can write models in which inequality emerges as if it were the product of free choices in a free market economy. You can also model a man's empty house as if he had called in the removal men - but if he has in fact been burgled, your models miss something.
I fear that some free market advocates - not all by any means, but some - are mistaking the map for the terrain. They forget that the textbook perfect competition model is not a description of reality but rather of a utopia against which to assess actually-existing markets. And sometimes - not always but in some important respects - they fall well short. ...
