Abstract
Competitive, spatial price equilibrium models have been used extensively by international agricultural trade economists as research and policy analysis tools. These mathematical models of international trade are solved on large mainframe computers. It has become feasible to solve small spatial price equilibrium models with microcomputers. This report describes a microcomputer program designed to solve small, single commodity spatial equilibrium models. The program, GTP (Generalized Transportation Problem), was developed on an IBM PC-XT personal computer, but it should run on most microcomputers based on the 8086 and 8088 microprocessors.
