In this paper we discuss the axiomatic approach to poverty measures and propose a unified framework for the Sen indices of poverty intensity which shows an explicit connection between the indices and their common underlying social evaluation function. We also identify the common multiplicative...

This paper proposes a unified framework for the Sen indices of poverty intensity, which shows an explicit connection between the indices and the common underlying social evaluation function. This paper also identifies the common multiplicative decomposition of the indices that allows simple and...
