Although the college-high school wage gap for younger men has doubled over the past 30 years, the gap for older men has remained nearly constant. We argue that these shifts reflect changes in the relative supply of highly-educated workers across age groups. Cohorts born in the first half of the...

In this paper, I examine the effect of business cycles on the employment, earnings, and income of persons in different demographic groups. I classify individuals by sex, education, and race. The analysis uses data from the Current Population Survey's Outgoing Rotation Group file, covering the...

I examine the specialization of US commuting zones in AI-related occupations over the 2000 to 2018 period. I define AI-related jobs based on keywords in Census occupational titles. Using the approach in Lin (2011) to identify new work, I measure job growth related to AI by weighting employment...

Using data from the Panel Study of Income Dynamics and a proprietary sample of semi-skilled production workers, this paper investigates the reasons for the discontinuous increase in wages associated with graduation from high school. Associated with graduation from high school, we find a...

The quality of governance depends on public sector worker productivity. We use micro data from China to document that judges are less productive on polluted days. Building on the insights of Alchian and Kessel (1962), we discuss the role of organization design and the incentives of public versus...

Increasing evidence indicates the importance of management in determining firms' productivity. Yet, causal evidence regarding the effectiveness of management practices is scarce, especially for high-skilled workers in the developed world. In an eight-month field experiment measuring the...

Can microcredit help unlock a poverty trap for some people by putting their businesses on a different trajectory? Could the small microcredit treatment effects often found for the average household mask important heterogeneity? In Hyderabad, India, we find that "gung ho entrepreneurs" (GEs),...

We study how access to high-skill labor affects the outcomes of start-up firms. We obtain exogenous variation in firms' ability to access skilled labor by using win rates in H-1B visa lotteries. Relative to other firms that also applied for H-1B visas, firms with higher lottery win rates are...

We study the impact of firm level choices of ICT, R&D, exporting and importing on the evolution of productivity and its bias towards skilled occupations. We use a novel measure of the propensity of a firm to engage in technology investment and adoption: its employment of workers with STEM...
