This paper characterizes efficient labor-market allocations in a labor selection model. The model’s crucial aspect is cross-sectional heterogeneity for new job contacts, which leads to an endogenous selection threshold for new hires. With cross-sectional dispersion calibrated to microeconomic...

In the Great Recession most OECD countries used short-time work (publicly subsidized working time reductions) to counteract a steep increase in unemployment. We show that short-time work can actually save jobs. However, there is an important distinction to be made: While the rule-based component...

Using 136 United States macroeconomic indicators from 1973 to 2017, and a factor augmented vector autoregression (FAVAR) framework with sign restrictions, we investigate the effects of three structural macroeconomic shocks - monetary, demand, and supply – on the labour market outcomes of black...

We investigate cyclical changes in workers' task portfolios, highlighting their direction, magnitude, and distribution. Task changes are not only very common but provide information about the skills required across jobs. During recessions, a larger share of employer switches do not involve task...

In the Covid-19 crisis, most OECD countries have used short-time work (subsidized working time reductions) to preserve employment relationships. This paper studies whether short-time work can save jobs through stabilizing aggregate demand in recessions. First, we show that the consumption risk...

This paper points out an empirical failing of real business cycle models in which unemployment is endogenized through a matching function. One can easily choose a calibration to make the cyclical fluctuation in unemployment as large in the model as it is in the data, or to make the response of...

This paper analyses optimal income taxes over the business cycle under a balanced-budget restriction, for low, middle and high income households. A model incorporating capital-skill complementarity in production and differential access to capital and labour markets is de-veloped to capture the...
