Identifying Productivity and Amenity Effects in Interurban Wage Differentials
利用土地和劳动力市场均衡条件，结合近期搬家者数据估计城市均衡工资和租金，从而识别各城市工资中生产率和宜居性的相对贡献，发现两者对工资差异的影响大致相当。
This study focuses on the relative importance of amenity and productivity differences in determining wage differentials across urban areas.The approach developed takes advantage of the connection between land and labor market clearing conditions required for locational equilibrium of households and firms.Data on recent movers are used to estimate equilibrium wages and rents for a sample of metropolitan areas.This information is then used to identify amenity and productivity components of wages for each city in the sample.Using national estimates of the relative share of land in consumption and production, differences in productivity and amenities are found to be roughly equal sources of wage variation across the sample.
