Recall and Unemployment
基于1990-2013年美国收入与项目参与调查数据，发现大量失业工人返回原雇主，其失业和就业结果与换工作者差异显著；在搜索匹配模型中引入召回选项，放大了新工作发现和离职概率的周期波动。
We document in the Survey of Income and Program Participation covering the period 1990–2013 that a surprisingly large share of workers return to their previous employer after a jobless spell, and experience very different unemployment and employment outcomes than job switchers. The probability of recall is much less procyclical and volatile than the probability of finding a new employer. We add to a quantitative, and otherwise canonical, search-and-matching model of the labor market a recall option, which can be activated freely following aggregate and job-specific productivity shocks. Recall and search effort significantly amplify the cyclical volatility of new job-finding and separation probabilities.
