We develop a framework where mismatch between vacancies and job seekers across sectors translates into higher unemployment by lowering the aggregate job-finding rate. We use this framework to measure the contribution of mismatch to the recent rise in U.S. unemployment by exploiting two sources...

Takahashi (2014) has uncovered coding errors in our paper, Chang and Kim (2007)-henceforth, CK. We acknowledge and are embarrassed by these mistakes. We are grateful to Takahashi for uncovering them. While the correction decreases the volatility of the labor market wedge, we find that the main...

One long-standing hypothesis about science and engineering labor markets is that the supply of highly skilled workers is likely to be inelastic in the short run. We consider the market for computer scientists and electrical engineers (IT workers) and the evolution of wages and employment through...

We examine monthly variation in weekly work hours using data from 2003 to 2010. The data sources include the Current Population Survey (CPS) on hours/worker, the Current Employment Survey (CES) on hours/job, and the American Time Use Survey (ATUS) on both. The ATUS data minimize recall...

Changes in the work week drove a larger portion of changes in total labor input during the Great Depression of the 1930s than during other decades. Work-sharing policies appear to be responsible. Herbert Hoover created various work-sharing committees--led by key industrialists--which pushed for...

We consider two life cycle models of labor supply that use nonconvexities to generate retirement. In each case we derive a link between hours worked prior to retirement, the intertemporal elasticity of substitution for labor (IES), and the size of the nonconvexities. This link is robust to...

We use new PSID data on consumption and health, along with information on annual sick time, to estimate a structural labor supply model that incorporates a health capital stock with the traditional human capital learning-by-doing model. The estimates show strong evidence of learning by doing as...

This paper assesses the impact of pollution on worker productivity by relating exogenous daily variations in ozone with productivity of agricultural workers as recorded under piece rate contracts. We find robust evidence that ozone levels well below federal air quality standards have a...

The converging roles of men and women are among the grandest advances in society and the economy in the last century. These aspects of the grand gender convergence are figurative chapters in a history of gender roles. But what must the "last" chapter contain for there to be equality in the labor...

Teacher contracts that condition pay and retention on demonstrated performance can improve selection into and out of teaching. I study alternative contracts in a simulated teacher labor market that incorporates dynamic self-selection and Bayesian learning. Bonus policies create only modest...
