Econometric disequilibrium models∗
梳理非均衡文献的四大脉络，详述经典计量非均衡模型及其估计方法，讨论价格与工资刚性、最小条件及价格调整方程等批评与修正，并介绍均衡与非均衡假设检验及多市场非均衡模型。
Four basic strands in the disequilibrium literature are identified. Some examples are discussed and the canonical econometric disequilibrium model and its estimation are dealt with in detail. Specific criticisms of the canonical model,dealing with price and wage rigidity, with the nature of the min condition and the price-adjustment equation, are considered and a variety of modifications is entertained. Tests of the “equilibrium vs. disequilibrium” hypothesis are discussed, as well as several classes of models that may switch between equilibrium and disequilibrium modes. Finally, consideration is given to multimarket disequilibrium models with particular emphasis on the problems of coherence and estimation.
