Worker Heterogeneity, Selection, and Unemployment Dynamics in a Pandemic
使用新凯恩斯模型研究大流行引发的衰退对不同类型工人失业分布的影响，发现平时失业频繁且时间长的工人受冲击更大，即使初期大规模裁员或临时解雇也如此，货币政策对失业分布影响有限。
Abstract We employ a new Keynesian model with random search in the labor market and endogenous selection among heterogeneous workers to investigate the impact of a pandemic‐induced recession on the distribution of unemployment across workers. In such a recession, workers whose unemployment spells in normal times are inefficiently frequent and long are disproportionately affected. This remains true even when the pandemic initially causes mass layoffs that affect workers broadly or if many separations represent temporary layoffs. Monetary policy that responds to labor market variables affects unemployment for all workers but does relatively little for the distribution of unemployment across workers types.
