On the Internal Contradictions of the Law of One Price
AbstractAs stated originally, the venerable law of one price succinctly describes long-run equilibrium in a perfectly competitive market. The law was later amended, defining a market as the geographic area within which the same thing sells for the same price at the same time, allowance being made for transportation costs. Modified in that way, the law has two plausible interpretations. By one interpretation, every production site is a market. By the other, prices in fact do not differ by transportation costs. The transportation-cost amendment thus introduces internal contradictions that render the revised law of one price either useless or wrong. (JEL D40, L10) Copyright 2004, Oxford University Press.
