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 surveys the use of search and matching models in macroeconomics. It outlines the standard model, discusses its extensions, presents alternative formulations, considers the empirical evidence, and studies applications to macroeconomic questions such as business cycles, growth, and...

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...

Do firms reduce employment when their insiders (established, incumbent employees) claim higher wages? The conventional answer in the theoretical literature is that insider power has no influence on employment, provided that the newly hired employees (entrants) receive their reservation wages....

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....

The picture of U.S. labour market dynamics is opaque. Empirical studies have yielded contradictory findings and debates have emerged regarding their implications. This paper aims at clarifying the picture, which is important for the understanding of the operation of the labour market, for the...

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...

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...

The administration of benefits is a relatively neglected aspect of the analysis of disincentive effects of unemployment benefit systems. We investigate this issue with a field experiment in Hungary involving random assignment of benefit claimants to treatment and control groups, a method of...
