The poverty gap index for the whole population (I) takes the total aggregate shortfall from the poverty line divided by the number of people and the poverty line itself. Recently, however, economists have suggested several more complicated alternatives including Sen’s index, the Sen-Shorrocks-Thon (SST) index, and the Foster-Greer-Thorbecke (FGT) index (which, under some parameterizations is equivalent to H and I).

متن کاملOn Some Problems of Variable Population Poverty Comparisons
This paper demonstrates that the property of ‘replication invariance’, generally considered to be an innocuous requirement for the extension of fixed-population poverty comparisons to variable-population contexts, is incompatible with other plausible variableand fixed-population axioms.
