近日，中央财经大学中国财政发展协同创新中心教师罗伟杰的独立作者论文“Inequality and government debt: Evidence from OECD panel data”被经济学国际知名期刊Economics Letters接受发表。

论文分析了收入分配的变动如何影响政府债务。文章利用Luxembourg Income Study的数据，将源于劳动生产率所引起的收入不均等与源于资本收入所引起的收入不均等二者区分。文章通过OECD国家的数据发现，劳动收入不均等的加剧将扩大政府债务规模，然而资本收入不均等的加剧会在一定程度上缓解债务压力。

该论文发表于Economics Letters 2020年1月刊。Economics Letters成立于1978年，是Elsevier公司出版的学术同行评审经济学期刊，以快速、高效地传播经济学各个研究领域的新成果、新模型和新方法为宗旨。

Abstract: This paper analyzes how government debt can be caused by changes in the income distribution. Unlike Azzimonti et al. (2014), I distinguish between income inequality induced by differences in labor productivity and income inequality induced by differences in capital income, utilizing the Luxembourg Income Study. Using data for OECD countries, an increase in labor income inequality leads to higher debt level whilst capital income inequality is negatively associated with debt.
