Immigrant Links to the Home Country: Empirical Implications for U.S. Bilateral Trade Flows
研究移民与母国的联系（如市场知识、语言、偏好和商业关系）如何降低交易成本，促进美国与移民母国之间的双边贸易，实证表明这种联系历史上显著增加了贸易流量。
Immigrants' ties to their home countries can play a key role in fostering bilateral trade linkages. Immigrant ties include knowledge of home-country markets, language, preferences, and business contacts that have the potential to decrease trading transaction costs. Empirical results for the United States suggest that immigrant links have historically been important in increasing bilateral trade flows with immigrants' home countries. Copyright 1994 by MIT Press.
