The effect of location on finding a job in the Paris region
研究巴黎地区1300个市镇中，失业时长的空间差异是源于居民自选择还是真实的区位效应，发现个体特征仅解释30%的差异，而地方指标（主要与居住隔离相关）解释了剩余差异的70%。
Abstract Do spatial differences in unemployment duration reflect residential sorting or a true local effect? Focusing on the 1300 municipalities of the Paris region, we apply a methodology that disentangles individual and unspecified municipality effects. Estimating a proportional hazard model stratified by municipality and recovering a survival function for each municipality purged of individual observed heterogeneity, we show that local and individual characteristics add up in their contribution to unemployment duration. While only 30% of the spatial disparities in unemployment duration are explained by individual characteristics, 70% of the remaining disparities are captured by local indicators, mainly correlated with residential segregation.
