Previous studies have stressed that in ation dynamics exhibit a substantial disper- sion across sectors. Using US producer price data, we present evidence that sectoral in ation persistence is negatively correlated with market concentration, which is diffi- cult to reconcile with the prediction...

Wage determination under asymmetric information generates inefficiencies due to excess turnover. Severance pay and layoff taxes can improve efficiency. We show that inefficient separations can even be fully removed with fixed separation taxes in the case where the relevant private information is...

Under symmetric information, a job protection law which says that a principal who has hired an agent today must also employ him tomorrow can only reduce the two parties' total surplus. The law restricts the principal's possibilities to maximize her profit, which equals the total surplus, because...

Several European countries have reformed their labor market institutions. Incentive effects of unemployment benefits have been an important aspect of these reforms. We analyze this issue in a principal-agent model, focusing on unemployment levels and labor productivity. In our model, a higher...

In this paper, I explore how optimal aggregate dynamics can be shaped by the presence of moral hazard in unemployment insurance. I also analyze the optimal provision of unemployment insurance and the implications for the amount of cross-sectional heterogeneity. The economy that I consider embeds...

This paper characterizes optimal unemployment insurance (UI) in terms of estimable statistics in the presence of negative duration dependence for the unemployed, with endogenous callback rates generated by asymmetric information. I show how this characterization generalizes the standard...

We study the existence of a profitable unemployment insurance market in a dynamic economy with adverse selection rooting in information on future job losses. The new feature of the model is that the insurer and workers interact repeatedly. Repeated interactions make it possible to threaten...

Short-time work - a wage subsidy conditional on hour reductions - has become an important tool of labor market policy in many European countries. As the scope of these policies expanded, concerns about side effects due to adverse selection increased. We develop a model of job retention policies...

Job displacement insurance in the United States includes publicly mandated unemployment benefits and privately contracted severance pay, a scheduled benefit designed to compensate workers for reemployment wage losses and residual unemployment losses. Asymmetric information problems profoundly...
