One Giant Leap: Emancipation and Aggregate Economic Gains

Abstract

We characterize American slavery as inefficient, whereby emancipation generated substantial aggregate economic gains. Coercion distorted labor markets, raising the marginal cost of labor substantially above its marginal benefit. Production came at immense costs imposed on enslaved people that reduced aggregate economic surplus (the total value of output minus total costs incurred). Costs of enslavement are inherently difficult to quantify, which leads to a wide range of quantitative estimates from this conceptual shift, but we calculate that emancipation generated aggregate economic gains worth a 4%--35% increase in US aggregate productivity (or worth 7--60 years of technological innovation). Emancipation decreased output but decreased costs substantially more, illustrating the substantial potential for aggregate economic gains in the presence of severe sectoral misallocation.

Market Forces and Employer Racial Preferences: Evidence from Wartime Shortages

Abstract

This paper estimates the extent to which labor market tightness reduces employer racial preferences, a key prediction of canonical theories of discrimination. Using newly constructed data on 16.8 million historical job advertisements spanning 1900-1970 and 10 million newly digitized WWII draft registration cards, we exploit quasi-experimental variation from World War II draft rates across local labor markets as a shock to White labor supply. Higher draft rates significantly reduced White-preferred job advertisements by 1.1 percentage points per 10 percentage point increase in draft intensity, with effects persisting 15 years post-war. The draft shock enabled Black workers to access better-paying occupations relative to White workers by 1950, primarily through exit from agriculture and educational investment. White workers experienced a 29 percent wage decline while Black workers gained 24 percent despite increased Black labor supply, consistent with durable employer demand shifts rather than labor supply effects alone.

Abstract

Firms’ innovation strategies and investment decisions can be shaped by broader societal dynamics, including the emergence of large-scale protest movements. We study how U.S. racial justice demonstrations—particularly those gaining national prominence in the mid-2010s—affected firm behavior in sectors tied to the criminal legal system. Using a difference-in-differences design, we compare firms with connections to the legal system to otherwise similar firms within the same industry, before and after the onset of protest activity. We find that exposure led to an increase in venture investment, with effects concentrated in relatively smaller deals (under $1 million) and no observable impact on larger deals exceeding $20 million. We also document a rise in innovation output. These findings suggest that public mobilization around issues of justice and equity can influence firm strategy, reshaping capital allocation and innovation in politically salient sectors.

Abstract

Both theory and empirical research have shown that market frictions and behavioral biases account, in part, for lower than expected household stock market participation rates. However, research has identified only a limited number of factors affecting variation in household stock market participation. This paper examines the hypothesis that historical race-based trauma can influence current household financial market participation. Using restricted use Panel Study of Income Dynamics (PSID) data, we show exposure to historical race-based financial trauma is related to decreased stock market participation that cannot be explained by historical region-based racial exclusion. This has profound implications for wealth accumulation and the persistence of racial wealth inequality.
