The Concentration Index of a Binary Outcome Revisited
The binary variable is one of the most common types of variables in the analysis of income-related health inequalities. I argue that while the binary variable has some unusual properties, it shares many of the properties of the ratio-scale variable and hence lends itself to both relative and absolut...

The binary variable is one of the most common types of variables in the analysis of income-related health inequalities. I argue that while the binary variable has some unusual properties, it shares many of the properties of the ratio-scale variable and hence lends itself to both relative and absolute inequality analyses, albeit with some qualifications. I argue that criticisms of the normalization I proposed in an earlier paper, and of the use of the binary variable for inequality analysis, stem from a misrepresentation of the properties of the binary variable, as well as a switch of focus away from relative inequality to absolute inequality. I concede that my normalization is not uncontentious, but, in a way, that has not previously been noted. 2012-03-30T07:31:32Z 2012-03-30T07:31:32Z 2011 Journal Article Health Economics 1099-1050 (Electronic) 1057-9230 (Linking) http://hdl.handle.net/10986/5148 EN http://creativecommons.org/licenses/by-nc-nd/3.0/igo World Bank Journal Article |
