We study the appeal of basic preference conditions that underpin health inequality indices, including the widely used concentration index. We did a lab experiment in which 349 respondents had to choose repeatedly between two policies that generated a distribution of income and health among five groups in society. We found stronger support for preference conditions that focus on inequality in the marginal distribution of health (and income) than for preference conditions that favor reduced correlation between both dimensions. Respondents' choices were more in line with the principle of income related health transfers when policies did not affect the ranking of groups in terms of health. Respondents also expressed more concern about the correlation between income and health when health was expressed as a shortfall rather than an attainment. Support for the preference conditions was unaffected when all groups in society experienced the same absolute or relative health change.
我们研究了作为健康不平等指数基础的基本偏好条件的吸引力，包括广泛使用的集中指数。我们进行了一项实验室实验，其中 349 名受访者必须在两项政策之间反复选择，这两项政策在社会中的五个群体中产生收入和健康的分配。我们发现，对于关注健康（和收入）边际分布不平等的偏好条件的支持强于对于偏好条件的支持，后者有利于减少两个维度之间的相关性。当政策不影响群体在健康方面的排名时，受访者的选择更符合与收入相关的健康转移原则。当健康被表示为不足而不是实现时，受访者也对收入和健康之间的相关性表示更多关注。当社会中所有群体都经历相同的绝对或相对健康变化时，对偏好条件的支持不受影响。
