In the media: “Do African exports to China hurt labor rights? Here’s what we found.” Washington Post Monkey Cage, 3 March 2017

To investigate whether Africa’s exports to China influence labor practices in Africa, we reconsider the debate over trade’s influence on regulatory standards in exporting countries. The first generation of trade–regulation scholars asked whether high levels of exports influenced regulatory standards of exporting countries, with inconclusive results. The second generation of scholarship focused not on how much a country exported but to whom it exported, identifying a “California Effect” by which firms and consumers in (mostly developed) importing countries projected their high regulatory standards on less developed export partners. Structural change – especially the rise of China as a major importer – poses a challenge to these optimistic findings. Drawing on insights from the analysis of compositional data, this paper introduces a third generation of trade–regulation research, which suggests examining not only with whom a country trades, but also how the composition of markets in a country's export basket reshuffles over time. Specifically, we explore the possibility of a “Shanghai Effect” whereby African countries begin to reflect the lower labor standards of China, which has emerged as a major destination for their exports. We show that when a country increases exports to China, the net effect on domestic labor standards depends critically on the labor practices of other export destinations compositionally displaced by China exports. Our analysis of a panel of 49 African countries for the period 1985–2010 produces a small continent-wide estimate of China’s negative influence on African labor practices. In-sample simulation at the country level uncovers a moderate Shanghai Effect for a handful of countries only.
