On Macroeconomic Equilibrium with Stochastic Rationing
将随机配给机制引入非均衡宏观模型，证明随机配给下的有效需求与预期效用最大化一致，并分析凯恩斯失业、古典失业等四种配给均衡的静态比较。
The purpose of this paper is to apply the ideas of stochastic rationing mechanisms to a simple disequilibrium macroeconomic model. It has been shown that effective demands with stochastic rationing, as opposed to those derived from deterministic constraints (the Clower-Benassy or Dreze effective demand), are consistent with the maximization of expected utility, and are also capable of producing unsatisfied demand and supply in a quantity-constrained equilibrium. The well-known regime classification of quantity-constrained equilibria, i.e., Keynesian unemployment, classical unemployment, repressed inflation and underconsumption, is shown to be relevant in a macroeconomic framework with stochastic rationing. Comparative statics of quantity-constrained equilibria are worked out for different regimes.
