Cyclical Variations in Wage Differentials and Unemployment
在一般均衡框架下重新表述Reder模型，解释工资差异的周期性变动及其收窄趋势，并探讨其对当前失业特征和总就业波动的宏观含义。
This paper attempts to reformulate in a general-equilibrium framework M. W. Reder's model, which explains cyclical variations in wage differentials and their general tendencies to narrow. Specifically, the author focuses on the three aspects of his model: the microeconomic behavior of a firm under imperfect information about labor quality; the mechanism of the economy creating unemployment; and the interaction between wage differentials and unemployment. Its implications for the macroeconomic issues on the characteristics of current unemployment and the question of why aggregate employment fluctuates are also explored.
