The link between income inequality and economic growth remains poorly understood. The global economic crisis challenged numerous growth studies by highlighting considerable degrees of spatial interdependence among economies. The existence of fewer restrictions on factor movements prompted spatial redistributions of income inequalities. Our paper attempts to reestimate such inequality impacts across the EU by allowing for these redistributions. We employ the spatial Durbin error specification, and unlike other studies, we make statistical inferences along the lines of a welfare-adjusted production function. Our results lend support to the presence of spillover effects emanating from income redistribution larger than those from unemployment, knowledge, or human capital.

收入不平等与经济增长之间的联系仍然知之甚少。全球经济危机通过强调经济体之间相当大的空间相互依存关系，对众多增长研究提出了挑战。对要素移动的限制较少的存在促使收入不平等的空间再分配。我们的论文试图通过允许这些重新分配来重新估计整个欧盟的不平等影响。我们采用空间杜宾误差规范，并且与其他研究不同，我们根据福利调整后的生产函数进行统计推断。我们的结果为收入再分配所产生的溢出效应大于失业，知识或人力资本所产生的溢出效应提供了支持。
