This paper proposes an alternative formulation for the Sen-Shorrocks index of poverty intensity for survey data with sampling weights, and decomposes the Sen-Shorrocks index into the poverty rate, the average poverty gap ratio among the poor, and the overall Gini index of poverty gap ratios....

This paper uses estimates of the Sen-Shorrocks-Thon measure of poverty intensity in Canadian provinces, and the 95% confidence interval surrounding such estimates, for 1984, 1989 and 1991-1996 to compare Canadian provinces over time and internationally. Coinciding with more general social...

This paper proposes an alternative formulation for the Sen-Shorrocks-Thon (SST) index of poverty intensity that is appropriate for survey data with sampling weights. It also decomposes the SST index into the poverty rate, the average poverty gap ratio among the poor, and the overall Gini index...

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...
