This chapter describes the ‘Evolution of the Fuzzy-Set Approach to Multi-Dimensional Poverty Measurement’. The relevant key points in this chapter, which are preliminary to any discussion of the methods used for a multi-dimensional analysis of poverty, are the selection of the relevant dimensions and the indicators used to measure people's achievements in these dimensions. The authors also mention the related issue of the choice of deprivation thresholds and the weights assigned to each dimension, but they do not discuss them in a full way one in Betti et al. (2008). Rather, they simply state that the binary distinction between a 'bad state' and a ‘good state’ is too sharp because deprivation is likely to occur in degrees. Beginning with this consideration, they retrace and update the fuzzy-set approach (Zadeh, 1965) for measuring multi-dimensional poverty, which leads to the integrated fuzzy and relative method. This chapter is not only the basic reference point for remaining chapters in the first section but also a starting point in the development of a fuzzy approach to the measurement of any phenomenon in the social sciences.

Abstract
This chapter describes the ‘Evolution of the Fuzzy-Set Approach to Multi-Dimensional Poverty Measurement’. The relevant key points in this chapter, which are preliminary to any discussion of the methods used for a multi-dimensional analysis of poverty, are the selection of the relevant dimensions and the indicators used to measure people's achievements in these dimensions. The authors also mention the related issue of the choice of deprivation thresholds and the weights assigned to each dimension, but they do not discuss them in a full way one in Betti et al. (2008). Rather, they simply state that the binary distinction between a 'bad state' and a ‘good state’ is too sharp because deprivation is likely to occur in degrees. Beginning with this consideration, they retrace and update the fuzzy-set approach (Zadeh, 1965) for measuring multi-dimensional poverty, which leads to the integrated fuzzy and relative method. This chapter is not only the basic reference point for remaining chapters in the first section but also a starting point in the development of a fuzzy approach to the measurement of any phenomenon in the social sciences.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
