This paper studies the forces which determine how diversity at a firm evolves over time. We consider a dynamic model o a single firm with two levels of employees, the entry level and the upper level. In each period, the firm selects a subset of the entry-level workers for promotion to the upper...

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...

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...
