Familiarity Breeds Investment: Diaspora Networks and International Investment Aug 01, 2010 By David Leblang Familiarity Breeds Investment: Diaspora Networks and International Investment Familiarity Breeds Investment: Diaspora Networks and International Investment What explains cross-national patterns of international portfolio and foreign direct investment (FDI)? While existing explanations focus on the credibility of a policy maker’s commitment, we emphasize the role of diaspora networks. We hypothesize that diaspora networks—connections between migrants residing in investing countries and their home country—influence global investment by reducing transaction and information costs. This hypothesis is tested using dyadic cross-sectional data for both portfolio and FDI. The findings indicate that even after controlling for a multitude of factors, disapora networks have both a substantively significant effect and a statistically significant effect on cross-border investment.

Response to epidemics in complex humanitarian crises— such as the recent cholera epidemic in Yemen and the Ebola epidemic in the Democratic Republic of Congo— is a global health challenge of increasing scale. The thousands of Yemeni and Congolese who have died in these years-long epidemics demonstrate the difficulty of combatting even well-known pathogens in humanitarian settings. The novel severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) may represent a still greater threat to those in complex humanitarian crises, which lack the infrastructure, support, and health systems to mount a comprehensive response. The Political Economy of Exchange Rate Regimes in Transition Economies Research Leblang: How resettling Afghan refugees might help Afghanistan’s future News In an article for The Washington Post, Batten's David Leblang and co-author Margaret Peters explain how migrants help their home countries by building trade ties and by sending back both cash and political knowledge. Climate, Violence, and Honduran Migration to the United States News Migration from Honduras to the U.S. has been growing for years. New research by Batten's David Leblang, director of the Global Policy Center, and Duke University's Sarah Bermeo suggests the movement is a result of persistent violence coupled with food insecurity linked to climate change. Leblang and Bermeo wrote about their findings in a blog for Brookings.
