The primary goal of our paper is to quantify the importance of imperfect competition in the U.S. labor market by estimating the size of rents earned by American firms and workers from ongoing employment relationships. To this end, we construct a matched employer-employee panel data set by...

Whether immigrants advance in labor markets relative to natives as they gain experience is a fundamental question in the economics of immigration. For the US, it has been difficult to answer this question for the period when the immigration rate was at its historical peak, between the 1840s and...

Using weekly administrative payroll data from the largest U.S. payroll processing company, we measure the evolution of the U.S. labor market during the first four months of the global COVID-19 pandemic. After aggregate employment fell by 21 percent through late-April, employment rebounded...

Previous studies for developed countries show negative short-run impacts of automation on employment and earnings. In this paper, we instead examine whether automation by a key trading partner can hurt workers in a developing country. We specifically focus in Colombia's labor market, and how the...

While there is a large literature on gender differences in important childhood developmental inputs in developing countries, the evidence for developed countries is relatively limited. I investigate gender differences in some of these inputs in the US and Canada. In the US very low birthweight...

A large body of literature suggests that the first years of life are critical for long-term economic, health and social outcomes. However, the effect of public programs on early life skills formation is largely unknown due to data limitations. In this paper we use novel data from a large...

After adjusting for sample-selection bias, I find a net decline in average stature of 0.64 inches in the birth cohorts of 1832--1860 in the US. This result supports the veracity of the Antebellum Puzzle--a deterioration of health during early modern economic growth in the US. However, this...

Using data on the near-universe of online US job vacancies collected by Burning Glass Technologies in 2016, we calculate labor market concentration using the Herfindahl-Hirschman index (HHI) for each commuting zone by 6-digit SOC occupation. The average market has an HHI of 4,378, or the...

International trade exposure affects job creation and destruction along the intensive margin (job flows due to expansions and contractions of firms' employment) as well as along the extensive margin (job flows due to births and deaths of firms). This paper uses 1992-2011 employment data from the...

In this paper, we use 2008-2013 American Community Survey data to update and further probe Dahl and Moretti's (2008) son preference results, which found evidence that having a female first child increased the probability of single female headship and raised fertility. In light of the substantial...
