Most spatial equilibrium studies done in the past have focused on macro problems of an industry or a commodity. There are, however, important applications for spatial models in analyses of efficient resource use on the micro or firm level.

One important area of application is in analysis of the efficiency of single-firm marketing systems. Many cooperatives and other agribusiness firms have developed systems for marketing agricultural commodities or distributing farm supplies. These systems involve multiple assembly and distribution points, and often some processing function is performed between the points of origin and final destination.
