Wage Dynamics, Cohort Effects, and Limited Commitment Models
分析了一个企业不能根据入职年份进行工资歧视的模型，发现工资动态与Beaudry和DiNardo（1991）的实证结果一致，并指出该结果不能区分不同工人承诺模型。
In this paper we analyse a model in which firms cannot pay discriminate based on year of entry to the firm, and argue that the wage dynamics are consistent with the empirical results of Beaudry and DiNardo (1991). Their results have been interpreted as supporting a model in which workers are ex post mobile. Since in our model worker mobility/commitment does not affect the optimal contract, it is argued that existing empirical research does not discriminate between different models of worker commitment.
