The Cream of the Crop? Geography, Networks, and Irish Migrant Selection in the Age of Mass Migration
利用20世纪初爱尔兰新数据，研究发现大规模移民时代（1850-1913）欧洲并未流失最优秀人才，农民之子与文盲男性移民率反而高于识字和有技能者，移民率在更贫困且移民网络更强的农业社区最高。
With more than 30 million people moving to North America during the Age of Mass Migration (1850–1913), governments feared that Europe was losing its most talented workers. Using new data from Ireland in the early twentieth century, I provide evidence to the contrary, showing that the sons of farmers and illiterate men were more likely to emigrate than their literate and skilled counterparts. Emigration rates were highest in poorer farming communities with stronger migrant networks. I constructed these data using new name-based techniques to follow people over time and to measure chain migration from origin communities to the United States.
