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...

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...

Estimates are presented of the inverse elasticity of supply of nursing services to the individual hospital, a quantity which is a natural measure of employer market power. The estimates corresponding to employment changes taking place over one year are quite high (in the neighborhood of 0.79)...

We document systematic differences in wage and earnings inequality between and within occupations and show that these differences are intimately related to systematic differences in labor supply across occupations. We then develop a variant of a Roy model in which earnings are a non-linear...

The close connection between US and China in scientific research and education in the 2000s produced a large group of China-born researchers who work in the US ("diaspora") and a larger group of China-born researchers who gained US-research experience and returned to do their research in China...

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...

How do noncompete agreements between workers and firms affect wages and employment in equilibrium? We build a tractable framework of wage posting with on-the-job search and large employers that provides a natural laboratory to assess anti-competitive practices in the labor market. We...
