A measure of association is row-size invariant if it is unaffected by the mutliplication of all entries in a row of a cross-classi…cation table by a same positive number. It is class-size invariant if it is unaffected by the mutliplication of all entries in a class (i.e., a row or a column). We...

This paper aims to explore properties that guarantee that multidimensional poverty indices are sensitive to the distribution among the poor, one of the basic features of a poverty index. We introduce a generalization of the monotonicity sensitivity axiom which demands that, in the...
