Immigration and ethnic histories have tended to focus on migration patterns and community formations among the laboring and working classes that predominated global migrations in the late nineteenth and early twentieth centuries. Recognizing that the era of mass migration was also the era of global capitalism, this roundtable brings together scholars whose work focuses on the economics plied by immigrant and ethnic capitalists and petty capitalists, in transnational, national, and colonial contexts. Rebecca Kobrin will discuss the role of Jewish immigrant credit and banking in the trans-Atlantic migration trade. Sophie Loy Wilson will discuss the “ghost economies” of Chinese Australians during the era of Chinese exclusion (White Australia). Simone Cinotto will discuss Fascist Italy’s efforts to bring a hyper-modern model of global food production and consumption to its colonial settlers in Ethiopia. The Roundtable will feature brief presentations by the panelists on their respective projects and a conversation between them and with the audience that will aim to elucidate similarities and differences across these case studies, and consider whether there are common themes and problematics that might define a subfield called Immigrant Economies.
