We show that Covid-19 illnesses persistently reduce labor supply. Using an event study, we estimate that workers with week-long Covid-19 work absences are 7 percentage points less likely to be in the labor force one year later compared to otherwise-similar workers who do not miss a week of work...

Professions play a key role in determining the division of labor and the returns to skilled work. This paper studies the productivity difference between physicians and nurse practitioners (NPs), two health care professions performing overlapping tasks but with stark differences in background,...

We ask how competition influences the prescribing practices of physicians. Law changes granting nurse practitioners (NPs) the ability to prescribe controlled substances without physician collaboration or oversight generate exogenous variation in competition. In response, we find that general...

More than ten percent of Americans with recent work experience say they will continue social distancing after the COVID-19 pandemic ends, and another 45 percent will do so in limited ways. We uncover this Long Social Distancing phenomenon in our monthly Survey of Working Arrangements and...

To better understand the tight post-pandemic labor market in the US, we decompose the decline in aggregate hours worked into the extensive (fewer people working) and the intensive margin changes (workers working fewer hours). Although the pre-existing trend of lower labor force participation...

This paper builds a world atlas of child penalties in employment based on micro data from 134 countries. The estimation of child penalties is based on pseudo-event studies of first child birth using cross-sectional data. The pseudo-event studies are validated against true event studies using...

Employment and participation rates for US prime age women rose steadily during the second half of the 20th century. In the last 30 years, however, those rates stagnated, even as employment and participation rates for women in other industrialized countries continued to rise. I discuss the role...

Using population-level administrative data, we study labor market externalities stemming from age-specific employment protection legislation (EPL) targeted towards older workers. Our results show no economically meaningful overall effects of the EPL on employment or earnings of either men or...

We examine union-non-union differentials in wages and hours in the United States over the last 50 years using data from the Current Population Survey (CPS). The regression-adjusted difference between union members' and non-members' hourly earnings has been falling since the Great Recession. The...

This paper explores how historical gender roles become entrenched as norms over the long run. In the historical United States, gender roles on the frontier looked starkly different from those in settled areas. Male-biased sex ratios led to higher marriage rates for women and lower for men. Land...
