中文摘要
本文通过构建统一框架，估计户主收入、配偶收入和转移收入的永久性与暂时性变异，以及这些收入来源之间的永久性与暂时性相关性，从而考察家庭收入动态的驱动因素。利用PSID 1970-2018年数据进行的完整分解显示，仅户主收入的暂时性变异就占家庭收入总不平等的一半以上。针对户主收入暂时性冲击的保险主要来自转移收入，而非配偶收入。配偶收入的永久性和暂时性变异均对家庭收入不平等具有均等化效应。
Abstract
This paper examines the driving forces of family income dynamics by developing a unified framework to estimate permanent and transitory variation in head earnings, spouse earnings, and transfer income, as well as permanent and transitory correlations between these income sources. A complete decomposition using the PSID 1970–2018 shows that transitory variation in head earnings alone accounts for more than half of the total family income inequality. Insurance against transitory shocks to head earnings comes primarily from transfer income rather than spouse earnings. Both permanent and transitory variations in spouse earnings have an equalizing effect on family income inequality.
