Global Inequality in Well-being Dimensions
研究了1992-2004年间各国在人类发展指数的寿命、知识和物质生活水平三个组成部分上的全球不平等，发现各组成部分的变化趋势与整体指数不同，尤其是寿命部分的不平等在上升。
Abstract This paper contributes to the literature on global inequality in multidimensional well-being by examining inter-country disparities in the longevity, knowledge and standard of material living components of the well-known and widely-used Human Development Index for the years 1992–2004. It differs from previous studies by examining global inequality in each of the components of this index alongside that of the index as a whole, thus side-stepping ambiguities over weighting that are inherent to multidimensional well-being indices. The Gini coefficient, both population and non-population weighted, is used to measure the extent of inequality. Results indicate that the different components often provide very different information to the index as a whole, especially with respect to changes in global inequality over time. Most component variables show declines in global inequality, whereas the longevity component exhibits increased inequality since 1992.
