Working Papers

Racial and Ethnic Inequality and the China Shock

Abstract: This paper examines how the labor market effects of import competition vary across Black, Hispanic, and white populations. For a given level of exposure to imports from China, we find no evidence that minority workers are relatively more harmed than white workers in terms of their manufacturing employment. However, exposure to trade shocks varies greatly across groups. Black workers are less likely to live in areas or work in industries facing import competition, resulting in less negative effects of the China shock on manufacturing employment relative to whites. Black workers also benefit disproportionately from the shift towards non-manufacturing employment resulting from the China shock, partially due to their overrepresentation in services at baseline. In contrast, Hispanic workers are overrepresented in exposed industries, though not in exposed geographic areas, meaning that on net they face greater manufacturing employment losses relative to whites. In addition, they experience relative losses in non-manufacturing employment, largely due to their lower educational attainment and baseline industry mix. Overall, the China shock increased the Hispanic-white employment gap by about 5%, though these effects are short lived and converge later in the time period we study. However, the China shock narrowed the Black-white employment gap by about 15%. While many labor market trends in recent decades have served to exacerbate Black-white gaps, import competition is a modest offsetting force.
