The Roots of Health Inequality and the Value of Intrafamily Expertise
利用瑞典医疗招生抽签和学位时间差异，发现家庭中有医生能提升预防性健康投资、改善健康并延长寿命，模拟政策可缩小18%的死亡率-收入梯度，表明健康专业知识接触差异是健康不平等的重要来源。
In the context of Sweden, we show that having a doctor in the family raises preventive health investments throughout the life cycle, improves physical health, and prolongs life. Two quasi-experimental research designs-medical school admission lotteries and variation in the timing of medical degrees-support a causal interpretation of these effects. A hypothetical policy that would bring the same health behavior changes and benefits to all Swedes would close 18 percent of the mortality-income gradient. Our results suggest that socioeconomic differences in exposure to health-related expertise may meaningfully contribute to health inequality.
