Education and income gradients in longevity: The role of policy
本文综述了教育与收入对健康和长寿的因果影响，指出政策效果因时间、地点和人群而异，并讨论了未来研究方向。
Education and income are strong predictors of health and longevity. In the last 20 years many efforts have been made to understand if these relationships are causal and what the possible role of policy should be as a result. The evidence from various studies is ambiguous: the effects of education and income policies on health are heterogeneous and vary over time, and across places and populations. I discuss explanations for these disparate results and suggest directions for future research.
