Chain Migration and Information Networks: Evidence From Nineteenth-Century Hesse-Cassel
研究了19世纪欧洲移民中链式迁移的长期影响，发现先前迁移会持续影响后续移民决策，且网络型移民比非网络型移民需要更少现金资产。
Chain migration was an important factor in European migrants' decisions in the nineteenth century. This article demonstrates that previous migrations have long-run effects and continue to impact the decisions of future migrants for many years. Chain migration produces not only more migration but different migrants. Migrants from over 1,300 different German villages are classified as networked and non-networked. The most definitive results from comparing the two types of migrants are the figures on cash assets because they support the model's prediction that socially networked migrants needed less cash than non-networked migrants to accomplish their migration goals.
