This paper extends the literature on monopsony and labor market concentration by taking a task-based approach and estimating the causal effect of concentration in the demand for skills on labor market outcomes. The prior literature has focused on industry and occupation concentration and likely...

Implementing a state-of-the-art machine learning technique for causal identification from text data (C-TEXT), we document that patents authored by female inventors are under-cited relative to those authored by males. Relative to what the same patent would be predicted to receive had the lead...

This paper builds, identifies and estimates a model of the labor market that features strategic interactions in wage setting and two-sided heterogeneity in order to shed light on the sources of wage inequality. We provide a tractable characterization of the model equilibrium and demonstrate its...

Recent wage growth at the bottom of the earnings distribution in the U.S. has reversed a decades-long trend of widening wage inequality. Numerous state and local minimum wage increases have overtaken an effectively non-binding federal minimum, and robust labor demand in the post-pandemic...

Labor market tightness following the height of the Covid-19 pandemic led to an unexpected compression in the US wage distribution that reflects, in part, an increase in labor market competition. Rapid relative wage growth at the bottom of the distribution reduced the college wage premium and...

Over the last thirty years, there has been a rise in several empirical measures of local labor market monopsony power. The monopsonist has a profit incentive to offer lower wages to local workers. Mobile high skill workers can avoid the lower monopsony wages by moving to other more competitive...

What is the impact of the minimum wage on the college wage premium? I show that job-ladder models imply that the effect should be small on impact---raising only the wages of workers bound by the minimum wage---and grow over time as workers slowly move up the job ladder. Guided by my theory, I...

National industrial concentration in the U.S. has risen sharply since the early 1980s, but there remains dispute over whether local geographic concentration has followed a similar trend. Using near population data from the Economic Censuses, we confirm and extend existing evidence on national...

We contribute a theory in which three channels interact to determine the degree of monopsony power and therefore the wedge between a worker's spot wage and her marginal product (henceforth, the wage markdown): (1) heterogeneity in worker-firm-specific preferences (nonwage amenities), (2) firm...

I show that buyer power of firms could either increase or decrease their technology adoption, depending on the direction of technical change and on which input markets are imperfectly competitive. I examine this relationship empirically in a setting that features both concentrated labor markets...
