摘要

2010年至2019年，美国个人收入不平等几十年来首次下降，但家庭收入不平等继续加剧。不平等趋势之间的不协调达到了近年来的最高水平。我们引入了一个框架来分解不平等趋势的差异。我们发现，2010年后不平等趋势中46%的不一致是由于家庭构成的变化，即年轻工人与父母同住的比例增加，个人收入低（但在增加），家庭收入高。剩下的不一致源于高收入家庭私人收入的增加和政府转移支付的再分配效应下降。个人收入不平等的减少并不意味着家庭收入不平等的减少。

Declining earnings inequality, rising income inequality: What explains discordant inequality trends in the United States?

From 2010 to 2019, personal earnings inequality declined in the United States (U.S.) for the first time in decades, yet household income inequality continued to increase. Discordance between the inequality trends reached its highest rate in recent history. We introduce a framework to decompose differences in inequality trends. We find that 46% of post-2010 discordance in inequality trends is due to changing household composition, namely a larger share of young workers living with their parents and combining low (but increasing) personal earnings with high household incomes. The remaining discordance stems from increases in private income among higher-earning households and declining redistributive effects of government transfers. Declines in personal earnings inequality do not imply declines in household income inequality.
