This paper studies the extent to which the cyclicality of gross and net occupational mobility shapes that of aggregate unemployment and its duration distribution. Using the SIPP, we document the relation between workers' (gross and net) occupational mobility and unemployment duration over the...

We consider a model of on-the-job search where firms offer long-term wage contracts to workers of different ability. Firms do not observe worker ability upon hiring but learn it gradually over time. With sufficiently strong information frictions, low-wage firms offer separating contracts and...

This paper analyzes the effect of labor and product market regulation in a dynamic stochastic equilibrium with search frictions. Modeling multiple-worker firms allows us to distinguish between the exit-and-entry (extensive) margin, and the hiring-and-firing (intensive) margin. We characterize...

This paper examines wage dispersion and wage dynamics in a stock-flow matching economy with on-the-job search. Under stock-flow matching, job seekers immediately become fully informed about the stock of viable vacancies. If only one option is available, monopsony wages result. With more than one...

A key question in labor market research is how the unemployment insurance system affects unemployment rates and labor market dynamics. We revisit this old question studying the German Hartz reforms. On average, lower separation rates explain 76% of declining unemployment after the reform, a fact...

I identify which theoretical model (random, stock-flow, or job queuing) best describes the matching mechanism in the labour market in Poland. The purpose of this work is to formulate policy recommendations aimed at increasing the number of matches. I use monthly registered unemployment data for...

In this paper, we study the role of coworker referrals for labor market outcomes. Using comprehensive Danish administrative data covering the period 1980 to 2005, we first document a strong tendency of workers to follow their former coworkers into the same establishments and provide evidence...

This paper studies quantitative properties of a multiple-worker firm search/matching model and investigates how worker transition rates and job flow rates are interrelated. We show that allowing for job-to-job transitions in the model is essential to simultaneously account for the cyclical...

Worker flows and job flows behave differently over the business cycle. The authors investigate the sources of the differences by studying quantitative properties of a multiple-worker version of the search/matching model that features endogenous job separation and intra-firm wage bargaining....
