Search frictions impede the labor market. Despite this indisputable fact, it is a priori unclear how job search costs affect search duration and unemployment: lower search costs make it easier to find a job, reducing search duration and unemployment, but may also increase the reservation wage,...

This paper develops a Walrasian equilibrium theory of establishment level dynamics and matching frictions and uses it to evaluate the effects of congestion externalities in the matching process and determine the government interventions that are needed to implement a Pareto optimal allocation....

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...

This paper is concerned with the business cycle dynamics in search-and-matching models of the labor market when agents are ex post heterogeneous. We focus on wealth heterogeneity that comes as a result of imperfect opportunities to insure against idiosyncratic risk. We show that this...

According to the standard union bargaining model, unemployment benefits should have big effects on wages, but product market prices and productivity should play no role in the wage bargain. We formulate an alternative strategic bargaining model, where labour and product market conditions...

The existing literature assumes that unemployment insurance (UI) affects the labor market through the job finding rate of eligible workers. I argue that this focus is too narrow. I show evidence for UI effects through three other margins: (i) search externalities; (ii) takeup of other welfare...

We examine the matching process using monthly panel data for local labour markets in Sweden. We find that an increase in the number of vacancies has a very weak effect on the number of unemployed workers being hired: unemployed workers appear to be unable to compete for many available jobs....

We show that in microdata, as well as in a search and matching model with flexible wages for new hires, wage rigidities of incumbent workers have substantial effects on separations and unemployment volatility. Allowing for an empirically relevant degree of wage rigidities for incumbent workers...

This paper studies the consequences of job loss. While previous literature has relied on mass layof fs and plant closures for identification, I exploit discontinuities in the likelihood of displacement generated by a last-in-first-out rule used at layof fs in Sweden. Matching data on individual...
