Price dispersion is a manifestation — and, indeed, it is the measure — of ignorance in the market. Dispersion is a biased measure of ignorance because there is never absolute homogeneity in the commodity if we include the terms of sale within the concept of the commodity. Thus, some automobile dealers might perform more service, or carry a larger range of varieties in stock, and a portion of the observed dispersion is presumably attributable to such differences. But it would be metaphysical, and fruitless, to assert that all dispersion is due to heterogeneity.

George Stigler

A rational man must be guided by the incentive system within which he operates. No matter what his own personal desires, he must be discouraged from certain activities if they carry penalties and attracted toward others if they carry large rewards. The carrot and the stick guide scientists and politicians as well as donkeys.
