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...

The fall of labor's share of GDP in the United States and many other countries in recent decades is well documented but its causes remain uncertain. Existing empirical assessments of trends in labor's share typically have relied on industry or macro data, obscuring heterogeneity among firms. In...

Given the level of its production in the U.S., a firm that produces more abroad tends to have fewer employees in the U.S. and to pay slightly higher salaries and wages to them. The most likely explanation seems to be that the larger a firm's foreign production, the greater its ability to...

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...

We show that the largest increase in unemployment benefits in U.S. history had large spending impacts and small job-finding impacts. This finding has three implications. First, increased benefits were important for explaining aggregate spending dynamics—but not employment dynamics—during the...

In 2021, the Biden Administration issued mandates requiring COVID-19 vaccinations for U.S. federal employees and contractors and for some healthcare and private sector workers. Although these mandates have been subject to legal challenges and some have been halted or delayed, rigorous appraisal...

We revisit the role of temporary layoffs in the business cycle, motivated by their unprecedented surge during the pandemic recession. We first measure the contribution of temporary layoffs to unemployment dynamics over the period 1979 to the present. While many have emphasized a stabilizing...

We describe the economic history of the rise of the American minimum wage between 1910 and 1968. Each new FLSA amendment led to a new peak in the real purchasing power of the national minimum. Exemptions to the FLSA were progressively closed and the share of workers covered finally increased...

Increased use of robots has roused concern about how robots and other new technologies change the world of work. Using numbers of robots shipped to primarily manufacturing industries as a supply shock to an industry labor market, we estimate that an additional robot reduces employment and wages...

The destructive economic impact of the Covid-19 pandemic was distributed unequally across the population. Gender, race and ethnicity, age, education level, and a worker's industry and occupation all mattered. We analyze the initial negative effect and the lingering effect through the recovery...
