Immigration and the Neighborhood
研究发现，在大都市区内，移民聚居的社区对本地居民的吸引力下降。通过地理扩散模型分析，移民密度增加导致本地居民迁出和房价升值放缓，且这种效应主要由基于种族和教育的居住隔离需求驱动，而非移民身份本身。
Within metropolitan areas, neighborhoods of growing immigrant settlement are becoming relatively less desirable to natives. We deploy a geographic diffusion model to instrument for the growth of immigrant density in a neighborhood. Our approach deals explicitly with potential unobservable shocks that may be correlated with proximity to immigrant enclaves. The evidence is consistent with a causal interpretation of an impact from growing immigrant density to native flight and relatively slower housing value appreciation. Further evidence indicates that these results are driven more by the demand for residential segregation based on ethnicity and education than by foreignness per se.
