Conciliating Absolute and Relative Poverty: Income Poverty Measurement Beyond Senâ€™s Model
Benoît Decerf ()
No 1701, Working Papers from University of Namur, Department of Economics
The properties of poverty measures based on absolute poverty lines are well-known. Their prop- erties have been extensively studied in the model proposed by Sen (1976). In contrast, the properties of relativist poverty measures â€“ measures based on non-absolute poverty lines â€“ have never been rigorously studied. This is not merely a theoretical issue: relativist measures do provide highly de- batable poverty comparisons. This becomes increasingly problematic as relativist poverty measures are more and more used by policy makers. This paper proposes an extension of Senâ€™s model designed for the study of relativist poverty measures. Several results show that classical properties have dif- ferent implications in the extended model and in Senâ€™s model. Finally, the paper characterizes an index specifically designed for non-absolute poverty lines (Decerf, 2015). This result provides the first characterization of a relativist poverty measure.
