Changes in rank-dependent income-related health inequality measures over time may usefully be decomposed into contributions due to changes in health outcomes and changes in individuals' positions in the income distribution. This paper establishes the normative implications of this type of decomposition by embedding it within a broader analysis of changes in the 'health achievement' index. We further show that the choice of health inequality measure implies a particular vertical equity judgement, which may be expressed on a common scale in terms of the concentration index of health changes that would be inequality preserving. We illustrate the empirical implications of this choice by reporting results from a longitudinal analysis of changes in income-related health inequality in Great Britain using the concentration, the Erreygers and Wagstaff indices of health attainments and the concentration index of health shortfalls. .
随着时间的推移,等级依赖的收入相关健康不平等指标的变化可以通过分解为健康结果变化和个体在收入分配中的位置变化的贡献来进行有益的分析。本文通过将其嵌入更广泛的“健康成就”指数变化分析中,确立了这种分解的规范意义。我们进一步表明,健康不平等指标的选择意味着特定的垂直公平判断,这种判断可以用健康变化的集中指数来表示,而健康变化的集中指数可以保持不平等。我们通过报告使用集中指数、埃雷杰斯和瓦格斯塔夫健康获得指数以及健康不足的集中指数对英国收入相关健康不平等变化的纵向分析的结果,说明了这种选择的实证意义。
