Job Turnover and Policy Evaluation: A General Equilibrium Analysis
构建了一个一般均衡模型来模拟企业间的工作重新配置过程，并用企业层面数据校准模型，评估了干扰这一过程的政策（如对工作破坏征税）对就业和福利的总体影响。
Recent empirical work indicates that job creation and destruction rates are large, implying significant amounts of job reallocation across firms. This paper builds a general equilibrium model of this reallocation process, calibrates it using data on firm-level dynamics, and evaluates the aggregate implications of policies that interfere with this process. We find that a tax on job destruction at the firm level has a sizable negative impact on total employment: a tax equal to 1 year's wages reduces employment by roughly 2.5 percent. More striking, however, are the welfare consequences: the cost in terms of consumption of this same tax is greater than 2 percent. Copyright 1993 by University of Chicago Press.
