Measurement of Consumer Gains from Market Stabilization
指出在部分均衡分析中，消费者从市场稳定化中获得的精确收益与近似值差异很小，关键在于正确设定稳定化的性质、需求曲率和供给反应，并提供了改进的近似和数值方法。
Abstract For most cases of practical significance in which partial equilibrium analysis is appropriate, there is little difference between exact measures of consumer gains from market stabilization and approximations such as expected change in marshallian or hicksian consumer surplus. Careful specification of the nature of stabilization is more crucial than the choice of welfare measure. It is important to represent correctly the demand curvature and supply response and to determine whether general equilibrium responses can be ignored. In any event, an improved analytical approximation and a simple numerical method for calculating the exact measures make it unnecessary to rely on suspect measures.
