Measurement of the monetary poverty in Cameroon using fuzzy measure theory

摘要

In this paper, we construct a unidimensional fuzzy Foster-Greer-Thorbecke(FGT) index which enables us to measure the monetary poverty. The approachadopted for that consists to build in a measurable space, a fuzzy measurement.This fuzzy measurement allows us afterwards to de?ne our unidimensional fuzzyFGT index as measurement of the fuzzy set of the poor. This fuzzy FGT index isafterwards used to measure the monetary poverty in Cameroon in the year 2014.The obtained results are compared with those obtained when the classical (non-fuzzy)FGT index is used.
