Recent studies show that firms are playing an increasingly important role in shaping wage inequality in advanced economies. We contribute to this literature by analysing wage inequality patterns and their firm dimension in Central and Eastern European countries. We use large, linked employer-employee datasets with data from the 2002-2014 period. We find that unlike in many other advanced economies, wage inequality levels have decreased in CEE countries, and particularly in those countries that previously had the highest wage inequality levels. The relative size of the between-firm component varied substantially across countries, and was largest in countries with the highest wage inequality levels. We further estimate the recentered influence function (RIF) regression and the Blinder-Oaxaca decomposition in order to investigate the micro-level determinants of wage inequality. Our findings indicate that the changes in wage inequality levels were mainly attributable to returns to workplace characteristics.

中欧和东欧的企业和工资不平等

最近的研究表明，企业在塑造发达经济体的工资不平等方面发挥着越来越重要的作用。我们通过分析中欧和东欧国家的工资不平等模式及其企业维度来为这些文献做出贡献。我们使用包含 2002 年至 2014 年期间数据的大型关联雇主-雇员数据集。我们发现，与许多其他发达经济体不同，中东欧国家的工资不平等水平有所下降，尤其是在那些以前工资不平等水平最高的国家。公司间部分的相对规模因国家而异，在工资不平等水平最高的国家中最大。我们进一步估计了重中心影响函数 (RIF) 回归和 Blinder-Oaxaca 分解，以研究工资不平等的微观决定因素。我们的研究结果表明，工资不平等水平的变化主要归因于工作场所特征的回报。
