Ethnic Diversity and Preferences for Redistribution
利用瑞典1985-94年难民安置政策带来的外生移民变化，结合面板调查数据，发现移民增加显著降低了居民对再分配的支持，尤其在高收入群体中更明显。
This paper investigates the causal link between the ethnic diversity in a society and its inhabitants' preferences for redistribution. We exploit exogenous variation in immigrant shares stemming from a nationwide program placing refugees in municipalities throughout Sweden during 1985-94 and match data on refugee placement to panel survey data on inhabitants of the receiving municipalities. We find significant, negative effects of increased immigration on the support for redistribution. The effect is especially pronounced among high-income earners. We also establish that estimates from earlier studies failing to identify causal effects are likely to be positively biased (i.e., less negative).
