In this paper, we propose a unified framework for the Sen indices of poverty intensity that shows an explicit connection between the indices and the common underlying social evaluation function. We also identify the common multiplicative decomposition of the indices that allows simple and...

This paper proposes a new and unified framework for the Sen and Sen-Shorrocks-Thon indices of poverty intensity, which shows an explicit connection between the two indices and the underlying social evaluation function. This paper also identifies the common multiplicative decomposition of the two...
