We develop a model for decomposing the covariance structure of panel data on firms into a part due to permanent heterogeneity, a part due to differential histories with unknown ages, and a part due to the evolution of economic shocks to the firm. Our model allows for the endogenous death of...

Do fluctuations of the labor wedge, defined as the gap between the firm's marginal product of labor (MPN) and the household's marginal rate of substitution (MRS), reflect fluctuations of the gap between the MPN and the real wage or fluctuations of the gap between the real wage and the MRS? For...

Our paper documents the large labor market wedges created by taxes, subsidies, and regulations included in the Affordable Care Act. The law changes terms of trade in both goods and factor markets for firms offering health insurance coverage. We use a multi-sector (intra-national) trade model to...

The search-and-matching model of the labor market fails to match two important business cycle facts: (i) a high volatility of unemployment relative to labor productivity, and (ii) a mild correlation between these two variables. We address these shortcomings by focusing on technological...

We document that an increasing fraction of jobs in the U.S. labor market explicitly pay workers for their performance using bonuses, commissions, or piece-rates. We find that compensation in performance-pay jobs is more closely tied to both observed (by the econometrician) and unobserved...

Firms often use non-linear incentive systems to motivate workers to achieve specified goals, such as paying bonuses to reach targets in sales, production, or cost reduction. Using administrative data from a major Chinese insurance firm that raised its sales targets and rewards for insurance...

We use tailored surveys and benchmarking in the flat-weave rug industry to better understand the shortcomings of standard productivity measures. TFPQ performs poorly because of variation in product specifications across firms. Controlling for specifications aligns TFPQ with lab benchmarks. We...

We study the nature of peer effects in the market for new cell phones. Our analysis builds on de-identified data from Facebook that combine information on social networks with information on users' cell phone models. To identify peer effects, we use variation in friends' new phone acquisitions...

We use a rich new body of data on the experiences of unemployed jobseekers to determine the sources of wage dispersion and to create a search model consistent with the acceptance decisions the jobseekers made. Heterogeneity in non-wage job values or amenities among jobseekers and jobs is a...
