Randomized experiments provide policy relevant treatment effects if there are no spillovers between participants and nonparticipants. We show that this assumption is violated for a Danish activation program for unemployed workers. Using a difference-in-difference model we show that the...

This paper offers an alternative theory for the increase in unemployment and wage inequality experienced in the United States over the past two decades. In my model firms decide the composition of jobs and then match with skilled and unskilled workers. The demand for skills is endogenous and an...

This Paper provides a simple matching model in which unemployed workers and employers can be matched together through social networks and through more efficient, but also more costly, methods. In this framework, decentralized decisions to utilize social networks in the job search process can be...

We present a structural framework for the evaluation of public policies intended to increase job search intensity. Most of the literature defines search intensity as a scalar that influences the arrival rate of job offers; here we treat it as the number of job applications that workers send out....

This paper surveys recent work in equilibrium models of labor markets characterized by search and recruitment frictions and by the need to reallocate workers across productive activities. The duration of unemployment and jobs and wage determination are treated as endogenous outcomes of job...

In this paper, we incorporate a positive theory of unemployment insurance into a dynamic overlapping generations model with search-matching frictions and on-the-job learning-by-doing. The model shows that societies populated by identical rational agents, but differing in the initial distribution...

We develop a structural non-stationary model of job search in the fashion of van den Berg (1990). Non-stationarity comes from the duration-dependence in benefits, in the arrival rate of job offers, and in wage offers. The model is then estimated using the French sample of the ECHP Survey...

This paper uses data on very small UK geographies to investigate the effective size of local labor markets. Our approach treats geographic space as continuous, as opposed to a collection of non-overlapping administrative units, thus avoiding problems of mismeasurement of local labor markets...

Some existing welfare programs (“work-first”) require participants to work in exchange for benefits. Others (“job search-first”) emphasize private job-search and provide assistance in finding and retaining a durable employment. This paper studies the optimal design of welfare programs...

This paper analyzes the reservation wages of first and second generation migrants. Based on recently collected and rich survey data of a representative inflow sample into unemployment in Germany, we empirically test the hypothesis that reservation wages increase from first to second generation...
