The Impact of Immigration on American Import Trade in the Late Nineteenth and Early Twentieth Centuries

Abstract

Studies of the contemporary period for the United States and for Canada have established that the presence of an immigrant population is associated with an increase in trade between the immigrants' host and origin countries. We wish to discover if such a protrade phenomenon was systematically associated with the massive inflow of immigrants to the United States during the 40 years preceding World War I. Applying a gravity model to U.S. imports of 78 commodities from 17 countries at five-year intervals, we find support for a broad pro-import immigrant effect, especially for more fmished and more differentiated goods.
