The downsides of density, including traffic congestion, contagious disease and crime, were common in Victorian London and classical Rome, just as they are today in Sao Paulo and Lagos. Our urban past provides lessons for developing world cities today. The first lesson, that I highlight, is that...

Urban flooding poses danger to people and places. People can adapt to this risk by moving to safer areas or by investing in private self-protection. Places can offset some of the risk through urban planning and infrastructure investment. By constructing a global city data set that covers the...

Due to population aging, GDP growth per capita and GDP growth per working-age adult have become quite different among many advanced economies over the last several decades. Countries whose GDP growth per capita performance has been lackluster, like Japan, have done surprisingly well in terms of...

This chapter reviews key literature studying the effects of wars on minority and underrepresented groups in U.S. labor markets in the 20th century. These labor markets, characterized by historically pervasive barriers to entry into certain occupations and industries, promotions, and fair pay for...

This paper estimates the magnitude and distribution of surplus from the knowledge worker gig economy using data from an online labor market. Labor demand elasticities determine workers' wages, and buyers' past market experience shapes both their job posting frequency and hiring rates. We find...

We investigate the source, magnitude, and unevenness of the procyclical forces that shape labor force participation, i.e., the participation cycle, which are important for the implementation of the maximum employment mandate. We show that these forces can be analyzed in real time using a flow...

This paper analyzes the heterogeneous effects of monetary policy on workers with differing levels of labor force attachment. Exploiting variation in labor market tightness across metropolitan areas, we show that the employment of populations with lower labor force attachment--Blacks, high school...

We study how human capital diversification, in the form of double majoring, affects the response of earnings to labor market shocks. Double majors experience substantial protection against earnings shocks, of 56%. This finding holds across different model specifications and data sets....

Flood events and flood risk have been increasing in the past few decades and have important consequences for the economy. Using county-level and ZIP-code-level data from the United States during 1998-2018, we document that (1) increased flood risk has a large negative impact on firm entry,...

We examine the state of the U.S. K-12 teaching profession over the last half century by compiling nationally representative time-series data on four interrelated constructs: occupational prestige, interest among students, the number of individuals preparing for entry, and on-the-job...
