Revisiting interregional wage differentials: New evidence from Spain with matched employer‐employee data
利用2006-2014年西班牙匹配雇主-雇员微观数据，研究各地区工资差异，并首次控制地区购买力平价差异，发现即使考虑个体和企业特征，地区间净工资差异仍显著存在。
Abstract This article examines wage differences across Spain's NUTS‐2 regions along the entire wage distribution based on matched employer‐employee microdata from 2006 to 2014. Unlike previous related studies, we properly control for differences in regional purchasing power parities, which are very large in practice. Although part of the raw regional wage differences observed is explained by differences between regions in productive structures, and, to a much lesser extent, in labor forces, noteworthy, very similar throughout the wage distribution regional differences net of composition effects arise even after controlling for a broad set of individual and firm characteristics.
