We present a job posting model of a labour market where jobs differ in characteristics other than wages and workers differ in their marginal willingness to pay for such characteristics. This creates incentives for firms to separate workers by posting multiple jobs. The interaction between these...

This paper explores the impact of undocumented as opposed to documented immigration in a model featuring search frictions and non-random hiring that is consistent with novel empirical evidence presented. In this framework, undocumented immigrants' wages are the lowest of all workers due to their...

We use linked longitudinal data on employers and employees to estimate how the 2003-2005 Hartz reforms affected the wages of displaced German workers after they returned to work. We also present a simple new method to decompose the wage effects into components attributable to selection on...

We ran a field experiment to causally identify the effects of intense survey participation on key labour market outcomes. We randomly excluded individuals willing to sign up for the German Job Search Panel, a high-frequency survey with a focus on job search and well-being. Using administrative...

In this paper, we exploit the worker-firm “link” information in the Linked Employer-Employee Database (LEED) to describe the patterns of employment intensity in jobs, matching between workers and firms, and the effect on job-level employment and earnings. First, we characterise workers’...

With the emergence of the Great Recession unemployment insurance (UI) is once again at the heart of the policy debate. In this paper, we review the recent theoretical and empirical evidence on the labor market effects of UI design. We also discuss policy issues related to UI design, including...

Many labor market models use both idiosyncratic productivity and a vacancy free entry condition. This paper shows that these two features combined generate an equilibrium comovement between matches on the one hand and unemployment and vacancies on the other hand, which is observationally...
