Abstract


In the present paper we suggest the use of Alkire-Foster (2009, 2011) dual cut-off method as a measure of multidimensional performance and a modified version of Gini’s delta to measure the concentration of achievements and/or failures. On either tails, the information on the joint distribution of achievements or deprivations can be used to measure their concentration. In particular we suggest the use of Gini’s delta to measure concentration – within a same tail - for different second order cut-off values k. We call this measure a measure of performance intensity. As an example we apply it to both tails of an OECD regional well-being performance indicator, and to the Multidimensional Poverty Index (MPI).
