SPATIAL DISEQUILIBRIUM
将单一商品空间均衡的极值原理扩展到刚性价格或价格管制导致的非均衡情形，涵盖消费品市场和要素市场，并用数学规划而非不动点技术求解空间非均衡模型。
ABSTRACT. The well‐known extremal principle for the solution of spatial equilibrium for a single commodity [Samuelson (1952)] is extended to deal with the case of disequilibrium caused by rigid prices and/or price controls. Both disequilibrium in consumer markets and in factor markets is covered. The study of disequilibrium is well known in general interdependent economic systems (the so‐called fixed‐price model of interdependent systems). The present work extends this approach to the spatial dimension, and shows how it is possible to represent and solve disequilibrium models by mathematical programming rather than by fixed‐point techniques.
