Shimer (2005) showed that a standard search and matching model of the labor market fails to generate fluctuations of unemployment and vacancies of the magnitude observed in US data in response to shocks to average labor productivity of plausible magnitude. He also suggested that wage...

Two thirds of US unemployment volatility is due to fluctuations in workers' job finding rate. In search and matching models, aggregate productivity shocks generate such fluctuations: through firms recruiting effort, they affect the rate at which workers and firms come into contact....

We develop a quantitative equilibrium model that features tax deductibility of employer-provided coverage, non-discrimination restrictions, fixed costs of coverage and firms that hire discrete numbers of workers in frictional labor markets. We use the calibrated model to understand what drives...

If legislating employment protection is a protracted process subject to time delays, then firms can dismiss workers before an increase in protection is implemented. Heightened risk of dismissal before implementation makes workers in countries with flexible labour markets reluctant to support...

We study welfare effects of public short-time compensation (STC) in a model in which firms respond to idiosyncratic profitability shocks by adjusting employment and hours per worker. Introducing STC substantially improves welfare by mitigating distortions caused by public unemployment insurance...
