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

Recent findings have revived interest in the link between real wage rigidity and employment fluctuations, in the context of frictional labor markets. The standard search and matching model fails to generate substantial labor market fluctuations if wages are set by Nash bargaining, while it can...

The debate over the influence of labour market flexibility on performance is unlikely to be settled by additional studies using aggregate data and making cross-country comparisons. While this approach holds little promise, micro-analysis of workers and firms and increased use of experimental...

Large-scale social experiments were pioneered in labor economics, and are the basis for much of what we know about topics ranging from the effect of job training to incentives for job search to labor supply responses to taxation. Random assignment has provided a powerful solution to selection...

Marinescu (2015) employs a methodology that does not attempt to address these challenges. A more innovative approach in Coglianese (2015) and Chodorow-Reich and Karabarbounis (2016) attempts to overcome these challenges by exploiting a sampling error in unemployment rates as an exogenous...

The previously documented trend toward more co- and multi-authored research in economics is partly (perhaps 20 percent) due to different research styles of scholars in different birth cohorts (of different ages). Most of the trend reflects profession-wide changes in research style. Older...

We build and analyze a new U.S. database that links 125 million applications to job vacancies and employer-side clients on Dice.com, an online platform for jobs and workers in software design, computer systems, engineering, financial analysis, management consulting, and other occupations that...

Categorical variables have no intrinsic ordering, and researchers often adopt a fixed-effect (FE) approach in empirical analysis. However, this approach has two significant limitations: it overlooks textual labels associated with the categorical variables; and it produces unstable results when...
