Empirical studies find that the age-variance profile of wages is U-shaped. The objective of this paper is to explore the driving forces of the U-shape in a model with search frictions. I introduce endogenous search effort and a fixed retirement age into Cahuc, Postel-Vinay, and Robin s (2006)...

We study an infinitely repeated principal-agent relationship with on-the-job search. On-the-job search is modeled as a dimension of the agent's effort vector that has no effect on output, but raises his future outside option. The agent's incentives to search are increasing in the degree to which...

This paper develops a labour market matching model with heterogeneous firms, on-thejob search and referrals. Social capital is endogenous, so that better connected workers bargain higher wages for a given level of productivity. This is a positive effect of referrals on reservation wages. At the...

The Stahl model is one of the most applied consumer search models, with many applications and an empirical background. The present paper explores an extension where sellers have asymmetries, which is mostly excluded by the literature. Sellers with heterogeneous numbers of stores are introduced,...

Using quarterly worker flow data of U.S. establishments, we find that an unexpected increase in uncertainty reduces hirings and quits, while it raises layoffs. This finding suggests that the real option effect of uncertainty is less important for employment decisions. Hence plants do not freeze...
