Fuzzy measurement of income inequality: a class of fuzzy inequality measures

摘要: The typical practice of income inequality evaluation is by using indices. Yet there no “best” measure as we know it, and hence, any conclusion based on an index must be subject to some doubts. Some authors even argued that the concept inequality, its very nature, vague, thus, cannot measured like exact concept. Motivated these considerations, this paper studies axiomatic fuzzifications measures. Consequently, a systematic method viewing conclusions comparisons in terms truth value statements developed. Furthermore, it shown (or fact, other fuzzy measure) can used construct confidence intervals for crisp
