Interpreting Trends in Intergenerational Mobility
通过动态模型研究代际传递，发现过去事件影响当前代际流动趋势，结构变化可能产生非单调的长期趋势，且流动下降可能反映过去收益而非近期机会不平等恶化。
Studying a dynamic model of intergenerational transmission, we show that past events affect contemporaneous trends in intergenerational mobility. Structural changes may generate long-lasting mobility trends that can be nonmonotonic, and declining mobility may reflect past gains rather than a recent deterioration of equality of opportunity. We provide two applications. We first show that changes in the parent generation have partially offset the effect of rising skill premia on income mobility in the United States. We then show that a Swedish school reform reduced the transmission of inequalities in the directly affected generation but increased their persistence in the next.
