Mortality Inequality
研究了寿命不平等如何随时间变化，及其与寿命延长和福利分配的关系，发现高收入国家中寿命不平等已大幅下降。
The paper describes how changes in the inequality of lifetimes have contributed to changes in the social distribution of welfare. I address the following questions: How can we measure inequality of lifetimes? How has this kind of inequality changed over time? How is this inequality related to increased longevity? How do these trends differ across and within countries? Unequal longevity was once a major source of social inequality, perhaps even more important in some sense than income inequality, for a long time. But over the last century, this inequality has declined drastically in high-income countries and is now comparatively trivial.
