When traditional methods for measuring economic welfare are scarce or unreliable, heights and BMIs are now well accepted measurements that represent biological conditions during economic development. Weight, after controlling for height, is an alternative measure to BMI for current net...

This paper charts the growth and development of the Latino population of the northeastern U.S. from 1970 to 2015. The relatively small population dominated by Puerto Ricans and concentrated in New York and a few other cities has evolved into a large, diverse, and more geographically dispersed...

The recent fall of labor's share of GDP in numerous countries is well-documented, but its causes are poorly understood. We sketch a "superstar firm" model where industries are increasingly characterized by "winner take most" competition, leading a small number of highly profitable (and low labor...

COVID-19 abruptly impacted the labor market with the unemployment rate jumping to 14.7 percent less than two months after state governments began adopting social distancing measures. Unemployment of this magnitude has not been seen since the Great Depression. This paper provides the first study...

The diffusion of automation technology raises questions about the future of work, leading to calls for policy interventions. The ongoing debate centers on the decisions made by technology adopters. In this paper, I study supply-side adjustments and their role in shaping policy outcomes. I focus...

I extend multi-unit auction estimation techniques to a setting in which firms can express cost complementarities over time. In the context of electricity markets, I show how the auction structure and bidding data can be used to estimate these complementarities, which in these markets arise due...
