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 ration among the poor, and the overall Gini index of poverty gap ratios....

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 undelying social evaluation function. This paper also identifies the common multiplicative decomposition of the two...

This paper examines the determinants of poverty intensity in US states and Canadian provinces in 1994 and 1997. Although most Canadian provinces had lower poverty than US states in 1994, by 1997 Canadian distinctiveness had greatly diminished. Was this because of trade liberalization, the...

The measurement of poverty intensity we use was initially advocated by Sen (1976), and modified recently by Shorrocks (1995). However, since Thon (1979, 1983) proposed arevision of the Sen index which in the limit is identical to that of Shorrocls, we refer henceforth to the SSR index. Section 2...
