摘要：In this paper an approach is used for defining the nature and extent of a geographic market and a product market relying on the concept of instantaneous causality. The market(s) for rice is (are) used for the empirical implementation of the technique. The results, based on both domestic (United States) and world prices, suggest that the extent of the geographic market changed between 1968 and 1986. This has obvious policy implications.
