This paper adds two-sided ex-ante heterogeneity and a production technology inducing sorting to the canonical Diamond-Mortensen-Pissarides (DMP) search and matching model. Ex-ante heterogeneity and sorting have important implications for the dynamic properties of the model. The modifications...

The purpose of this chapter is twofold. First, it reviews the model of search and matching equilibrium and derives the properties of employment and unemployment equilibrium. Second, it applies the model to the study of employment fluctuations and to the explanation of differences in unemployment...

The limited nature of data on employment referrals in large business and household surveys has so far impeded our efforts to understand the relationships among employment referrals, match quality, wage trajectories, and turnover. Using a new firm-level data set that includes explicit information...

In this paper, we provide a comprehensive overview of labour market dynamics in Western Ger- many by looking at gross worker flows. To do so, we use a subsample of the registry data collected by the German social security system, the IAB employment sample, for the time period 1975-2001. The...

In recessions, unemployment increases despite the—perhaps counterintuitive—fact that thenumber of unemployed workers finding jobs expands. On net, unemployment rises only becauseeven more workers lose their jobs. We propose a theory of unemployment fluctuations resting onthis...
