Sensitivity of Job Destruction to Vintage and Tenure Effects
在匹配模型中引入年代和任期效应，发现这能产生反周期的失业流入，减弱工作破坏对生产率冲击的强烈反应，并生成向下倾斜的贝弗里奇曲线，同时增加职位空缺、工作发现率和劳动力市场紧张度的波动性。
Abstract Matching models with endogenous job destruction typically deliver excessively volatile job destruction and moderate volatility of vacancies. In our model, vintage and tenure effects promote the creation of new matches that are temporarily more productive, while reducing the survival of temporarily less productive matches. This cleansing effect produces a counter‐cyclical inflow into unemployment, removes the strong response of job destruction to productivity shocks, and generates a downward‐sloping Beveridge curve, as in the data. The model also generates more volatility in vacancies, the job‐finding rate, and labor‐market tightness.
