This chapter assesses how models with search frictions have shaped our understanding of aggregatelabor market outcomes in two contexts: business cycle fluctuations and long-run (trend) changes. Wefirst consolidate data on aggregate labor market outcomes for a large set of OECD countries. We...

Existing models of equilibrium unemployment with endogenous labor market participation are complex, generate procyclical unemployment rates and cannot match unemployment variability relative to GDP. We embed endogenous participation in a simple, tractable job market matching model, show...

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...

In this paper we use information on the cyclical variation of labor market participation to learn about the aggregate labor supply elasticity. For this purpose, we extend the standard labor market matching model to allow for endogenous participation. A model that is calibrated to replicate the...

This paper uses data from the Health and Retirement Study to examine retirement and related labor market outcomes for the Early Boomer cohort, those in their mid-fifties at the onset of the Great Recession. Outcomes are then compared with older cohorts at the same age. The Great Recession...

Four years after the beginning of the Great Recession, the labor market remains historically weak. Many observers have concluded that "structural" impediments to recovery bear some of the blame. This paper reviews such structural explanations. I find that there is little evidence supporting...

In this paper, I propose a new Keynesian DSGE model with labor market search and matching frictions which replicates the low volatility and the moderate procyclicality of the labor force participation rate, that are observed in the United States at business cycle frequency. That being so,it can...

This paper considers a real business cycle model with search frictions in the labor market and labor supply which is elastic along the extensive (participation) margin. Previous authors have found that such models generate counterfactually procyclical unemployment and a positively-sloped...

This paper proposes a strategy to measure, in a unified setting, how the job finding probability and the job separation probability conditional on observable and unobservable individual characteristics varies over the business cycle. Recent papers by Shimer and Hall point out how new...
