This paper shows that the ancestry composition shaped by century-long immigration to the US can explain the current structure of global supply chain networks. Using an instrumental variable strategy, combined with a novel dataset that links firm-to-firm global supply chain information with a US...

This paper explores the impact of immigrants on the imports, exports and productivity of service- producing firms in the U.K. Immigrants may substitute for imported intermediate inputs (offshore production) and they may impact the productivity of the firm as well as its export behavior. The...

The decision to encourage or restrict high-skilled immigration has long been controversial. Advocates argue that high-skilled immigration is critical for firm competitiveness and innovation; critics argue that skilled immigrants displace native workers and drive down wages. The debate, however,...

Political economy accounts of economic integration strongly emphasize the importance of legal contract enforcement. We challenge extant research by showing that relational contracting, relationship-based contract enforcement, is more efficient for high-risk, human capital-intensive activities...

Venture capital firms predominantly source investments from local networks within tight geographic bounds. Against that pattern, VCs are increasingly investing internationally—but with substantial heterogeneity across firms in extent, location, and success. We propose a mechanism to explain...

Do immigrants undermine culture in a way that destroys productivity in destination countries? Some scholars have argued that because immigrants come from countries with dysfunctional social capital—norms and institutions— they will import it and pollute the social capital in destination...

In the last decades the number of refugees from conflict regions in Africa increased dramatically. West Africa is the cradle of migration from Sub-Saharan Africa to Europe, were most African migrants with overseas destinations live. The European Union shares dual responsibility for the...

The belief that immigrants generate beneficial externalities in their host countries, specifically in the form of an increased opportunity and ability of firms to expand their foreign trade, has recently been challenged by George Borjas in Heaven?s Door (1999, p. 97) as having no empirical...

Within the migration-trade nexus literature, this paper proposes a more carefully defined measure of migration business networks, and quantifies its impact on bilateral trade. Using cross-sectional data and controlling for the overall bilateral stock of migrants, the share of migrants employed...
