A new multiplicative decomposition for the Foster-Greer-Thorbecke poverty indices
This paper explores a unified framework for the study of changes in poverty over time as measured by the Foster-Greer-Thorbecke poverty indices. First we identify a multiplicative decomposition for the indices of this family as a product of the three components which should be involved in every poverty index: the incidence, the intensity and the inequality in the distribution of the income of t...
متن کاملThe Foster-Greer-Thorbecke Poverty Measures: Twenty Five Years Later
Twenty-five years ago the FGT class of decomposable poverty measures was introduced in Foster, Greer, and Thorbecke (1984). The present study provides a retrospective view of the FGT paper and the subsequent literature, as well as a brief discussion of future directions. We begin by describing the context and origins of our paper, and identify three categories of contributions: to measurement, ...
متن کاملDecomposing the Foster-Greer-Thorbecke Index of Vulnerability to Poverty
This paper applies the decomposition of the Foster-Greer-Thorbecke poverty index to the measurement of the individual vulnerability to poverty. I highlight that poverty risk can be expressed as a function of expected incidence, expected intensity and expected downward variability. An empirical illustration is provided using the British Household Panel Survey (BHPS) and the Survey on Household I...
متن کاملA Re-scaled Version of the Foster-Greer-Thorbecke Poverty Indices based on an Association with the Minkowski Distance Function
This note advances a family of poverty measures, Πα, which are derived as simple, normalized Minkowski distance functions. The Πα indices turn out to be the αth roots of the corresponding Foster, Greer and Thorbecke Pα indices. The re-calibration of Pα in terms of Πα could have certain possible advantages, which are reviewed in the note. While the Πα indices are not decomposable in the ordinari...
متن کاملA New Poverty Decomposition
This note proposes a new poverty decomposition that can be used to explain changes in poverty over time. The change in poverty is derived as the exact sum of four elements: (i) the overall growth effect, assuming inequality in the distribution does not change; (ii) the impact of differences in growth rates between the groups; (iii) the effect of the change in inequality within the different gro...
