Social insurance and retirement: A cross-country perspective
研究了养老金、残疾保险和医疗保险如何解释不同国家老年人劳动供给的差异，发现各国社保激励差异巨大，仅凭社保差异就能预测出比实际数据更大的跨国就业率变化。
We study the role of old-age pensions, disability insurance and healthcare in accounting for the differing labor supply patterns of older individuals across countries. We develop a life cycle model of labor supply and health with heterogeneous agents. In our framework, people choose when to stop working and when/if to apply for disability and pension benefits. We find that the incentives faced by older workers differ hugely across countries. In fact, based solely on differences in social insurance programs, the model predicts even more cross-country variation in the employment rates of people aged 55–69 than we observe in the data.
