Migration Networks and Location Decisions: Evidence from US Mass Migration
American Economic Journal: Applied Economics · 2021 · Bryan A. Stuart、Evan J. Taylor

中文摘要

本文研究在美国历史上的迁移事件中,出生城镇的迁移网络如何影响长期区位决策。我们开发了一种新方法来估计每个迁入地和迁出地迁移网络的强度。我们的估计表明,当一名随机选取的非裔美国人从南方出生城镇迁往某一目的地县时,平均另有1.9名黑人移民做出了同样的迁移。对于来自大平原地区的白人移民,该平均值仅为0.4。网络在将黑人移民与有吸引力的就业机会相连接方面尤为重要,并在迁移成本较低的迁移中发挥了更大作用。

Abstract

This paper studies how birth town migration networks affected long-run location decisions during historical US migration episodes. We develop a new method to estimate the strength of migration networks for each receiving and sending location. Our estimates imply that when one randomly chosen African American moved from a Southern birth town to a destination county, then 1.9 additional Black migrants made the same move on average. For White migrants from the Great Plains, the average is only 0.4. Networks were particularly important in connecting Black migrants with attractive employment opportunities and played a larger role in less costly moves.
