This paper characterizes long-run and short-run optimal fiscal policy in the labor selection framework. In a calibrated non-Ramsey decentralized equilibrium, labor market volatility is inefficient. Keeping fixed the structural parameters, the Ramsey government achieves efficient labor market...

Few skilled workers in the UK have flexible working time - GPs are the exception - most can only choose between unemployment, or full-time work, which has changed little in recent years, while part time work is mainly unskilled. This market rigidity imposes major welfare losses, in contrast to...

Labour productivity stagnated in the UK in the years between the financial crisis and the emergence of Covid-19. At the same time labour supply and employment grew strongly, driven primarily by net inward migration. While labour productivity should be independent of labour supplied in the long...

We show that in a search/matching model with endogenous participation in which workers are heterogeneous with respect to market productivity, satisfying the Hosios rule leads to excessive vacancy creation. The reason is that the marginal worker does not internalize the effect of his or her...

The empirical literature on employer learning assumes that employers learn about unobserved ability differences across workers as they spend time in the labor market. This article describes testable implications that arise from this basic hypothesis and how they have been used to quantify the...

We study job displacement in France. In the medium run, losses in firm-specific wage premium account for a substantial share of the overall cost of displacement. However, and despite the positive correlation between premium and productivity in the cross-section of firms, we find that workers are...

We analyse how changes in international trade integration affect productivity and the functional income distribution. To account for endogeneity, we construct a leave-out measure for international trade integration for country-industry pairs using international input-output tables. First, we...

This paper extends previous work on the identification of search models in which observed worker productivity is imperfectly observed. In particular, it establishes that these models remain identified even when employment histories are left-censored (i.e. we do not get to follow workers from...

Financial frictions are known to raise the volatility of economies to shocks (e.g. Bernanke and Gertler 1989). We follow this line of research to the labor literature concerned by the volatility of labor market outcomes to productivity shocks initiated by Shimer (2005): in an economy with search...
