Reemployment Probabilities and Returns to Matching
通过估计失业者的再就业概率，检验匹配函数中规模报酬不变的假设，发现该假设未被拒绝，即求职成功率仅取决于当地劳动力市场紧张程度，与市场规模无关。
The assumption of constant returns in the matching function, embodied in most bilateral search models, is crucial to ensure the uniqueness of the unemployment rate along a steady-state growth path. This article explores the empirical viability of this assumption by estimating individual reemployment probabilities on a sample of unemployment entrants. I apply hazard models to survey data on both completed and uncompleted unemployment durations. The hypothesis of constant returns to matching is not rejected, on the basis of the evidence that the job-finding hazard depends only on local labor market tightness and is independent of its size.
