A Counting Approach for Measuring Multidimensional Deprivation

Rolf Aaberge, Eugenio Peluso
2011 Social Science Research Network  
ABSTRACT A Counting Approach for Measuring Multidimensional Deprivation This paper is concerned with the problem of ranking and quantifying the extent of deprivation exhibited by multidimensional distributions  ...  which prove to admit decomposition into the mean and the dispersion of the distribution of multiple deprivations.  ...  In this paper we focus on multidimensional poverty measurement in situations where the multiple attributes in which an individual can be deprived are represented by dichotomized variables.  ...
