This paper develops the nonparametric identification of models with production complementarities, worker-firm specific disutility of labor and search frictions. Mobility in the model is subject to preference shocks, and we assume that firms can write wage contracts. We develop a constructive...

Empirical research in the social and medical sciences frequently involves testing multiple hypotheses simultaneously, increasing the risk of false positives due to chance. Classical multiple testing procedures, such as the Bonferroni correction, control the family-wise error rate (FWER) but tend...

We draw on a recombinant view of innovation, where being in a new location and/or multiple locations leads to exposure to novel combinations of ideas that increase the creativity of top scientists. Using a rich, unique dataset we helped assemble, we estimate the empirical relationship between...

This paper develops a control-function methodology accounting for endogenous or mismeasured regressors in hazard models. I provide sufficient identifying assumptions and regularity conditions for the estimator to be consistent and asymptotically normal. Applying my estimator to the subprime...

Many panel data methods, while allowing for general dependence between covariates and time-invariant agent-specific heterogeneity, place strong a priori restrictions on feedback: how past outcomes, covariates, and heterogeneity map into future covariate levels. Ruling out feedback entirely, as...

This article reviews the literature on automation and its impact on labor markets, wages, factor shares, and productivity. I first introduce the task model and explain why this framework offers a compelling way to think about recent labor market trends and the effects of automation technologies....

We consider large, permanent shocks to individual occupations whose arrival date is uncertain. We are motivated by the advent of self-driving trucks, which will dramatically reduce demand for truck drivers. Using a bare-bones overlapping generations model, we examine an occupation facing...

We study the impact of Federal alcohol Prohibition in 1919 on workers in the alcohol industry and their families using newly linked census records that allow us to follow spouses, sons and daughters. Immediately after Prohibition, men previously working in alcohol-related industries were less...

This chapter traces the evolution of the study of gender in the labor market, focusing on how academic thinking on this topic has evolved alongside real world developments in gender inequality from the 1980s to the present. We present a simple model of female labor supply to illustrate how...

Modern tech platforms provide workers real-time control over when they work, and increasingly, flexible pay: the option to be paid immediately after work. We investigate the labor supply effects of pay flexibility and the implications of present-biased preferences among gig-economy workers....
