Cointegration methods are increasingly used to test for market efficiency and integration. The economic rationale for these tests, however, is generally unclear. Using a simple spatial equilibrium model to simulate equilibrium price behavior, it is shown that prices in a well-integrated,...

Agricultural commodities are typically produced over an extensive spatial area and are costly to transport relative to their total value. These characteristics yield a complex set of spatial price linkages which are often studied to gain insights into the performance of markets. An extensive...

A computer system for implementing electronic markets on networks of personal computers is described. The program allows a researcher or teacher to design market simulations to meet a variety of goals, and records a complete set of market activities for analysis. Illustrations of example markets...
