European Migration, National Origin and Long‐term Economic Development in the United States
研究20世纪初欧洲移民的原籍国分布是否影响美国各县的长期经济发展，发现移民整体有正面作用，但原籍国制度质量并非当前发展水平的良好预测指标。
Have Irish, German, or Italian settlers arriving in the United States at the turn of the twentieth century left a trace that determines differences in economic development to this day? Does the national origin of migrants matter for long‐term development? This article explores whether the distinct geographic settlement patterns of European migrants according to national origin affected economic development across U.S. counties. It uses microdata from the 1880 and 1910 censuses in order to identify where migrants from different nationalities settled and then regresses current levels of economic development on settlement patterns according to national origin, using both ordinary least squares and instrumental variable approaches. The analysis controls for a number of factors that would have determined the attractiveness of different U.S. counties at the time of migration as well as current levels of development. The results indicate that while there is a strong and positive impact associated with overall migration, differences in the quality of the institutions of the countries of origin of the migrant are not necessarily a good predictor for current levels of economic development of U.S. counties.
