We build an analytically and computationally tractable stochastic equilibrium model of unemployment in heterogeneous labor markets. Facing search frictions within markets and reallocation frictions between markets, workers endogenously separate from employment and endogenously reallocate between...

We analyze a general search model with on-the-job search and sorting of heterogeneous workers into heterogeneous jobs. This model yields a simple relationship between (i) the unemployment rate, (ii) the value of non-market time, and (iii) the max-mean wage differential. The latter measure of...

The decisions of firms on investment and hiring play a crucial role in business cycle fluctuations. This paper explores their dynamic behavior in the presence of frictions. It does so within a unified framework, stressing their mutual dependence and placing the emphasis on their joint,...

We use a novel approach to studying the heterogeneity in the job finding rates of the nonemployed by classifying the nonemployed by labor force status (LFS) histories, instead of using only one-month LFS. Job finding rates differ substantially across LFS histories: they are 25-30% among those...

This paper links detailed 24-hour diary surveys in the United Kingdom (UK) over the last four decades to provide evidence on the increase in work effort in three specific dimensions: timing, nature, and composition. We rule out possible explanations behind these trends, finding that the decrease...

Although labor market "mismatch" often refers to an imbalances in supply and demand across occupations, mismatch within occupations can arise if skill requirements are changing over time, potentially reducing aggregate matching efficiency within the labor market. To test this, we examine changes...

We estimate Frisch elasticity in a labor market with high job turnover. In a context where only around 18% of the employed labor force has formal and stable jobs, we perform a fixed effects estimation as proposed by MaCurdy (1981) with a Heckman correction for selection into unemployment. We...

Existing research has shown that job displacement leads to large and persistent earnings losses for men, but evidence for women is scarce. Using administrative data from Germany, we apply an event study design in combination with propensity score matching and a reweighting technique to directly...

Who fares worse in an economic downturn, low- or high-paying firms? Different answers to this question imply very different consequences for the costs of recessions. Using U.S. employer-employee data, we find that employment growth at low-paying firms is less cyclically sensitive. High-paying...

This paper presents a theory explaining the labor market matching process through microeconomic incentives. There are heterogeneous variations in the characteristics of workers and jobs, and firms face adjustment costs in responding to these variations. Matches and separations are described...
