The spatial extent of agglomeration economies across the wage earnings distribution
使用分位数回归，研究四个距离带内的经济总量对个人工资收入的影响，发现集聚效应在25公里内显著，且对工资分布的影响不对称。
Abstract We investigate the spatial extent of agglomeration economies across the wage earnings distribution using economic mass (total employment) in four distance bands around each individual’s establishment in a quantile regression framework. We control for observable and unobservable individual and establishment characteristics. Remaining endogeneity in the model is assessed with a set of instrumental variables. Results indicate a positive effect of economic mass on wage earnings up to 25 km away from the establishment. The spatial extent of agglomeration economies is similar across the wage earnings distribution. However, increases in economic mass shift the wage earnings distribution in a nonsymmetric way.
