Fuzzy Version Of The Jalan-Ravallion Approach: Evidence From Tunisia

[Full Text]

Chronic poverty, Fuzzy set approach, Membership function, Transient poverty, Tunisia



Based on the recent literature, the present paper offers a new methodology to analyze poverty dynamics components. Building on the fuzzy subset theory, the aim of this study is to make available a new replay to the traditional Jalan-Ravallion approach by proposing new measures for chronic, transient and persistent poverty and provide new measure of observed poverty for each attribute. This paper proposes a new method using a membership function and fuzzy rules to identify to what extent individuals can be considered as poor/non-poor. According to the proposed membership function, a relative fuzzy index are adopted to compute an aggregation method of fuzzy individual poverty. The empirical assessment has been conducted using data of the Tunisian household survey from 2005 to 2010 and has been given arise to some potential policy recommendations through the fuzzy estimation results.
