摘要

We reconsider the principles of diminishing transfer and dual diminishing transfer. It appears that if a Rank Dependent Expected Utility (RDEU) maximizer respects the principle of diminishing (resp. dual diminishing) transfer, then he or she behaves in accordance with the Expected Utility model (resp, Yaari's dual model). This leads us to define the principle of strong diminishing transfer, which is a combination of the principles of diminishing and dual diminishing transfer. We give necessary conditions for a RDEU maximizer to respect this principle, These results are applied to the problem of inequality measurement. (C) 2001 Elsevier Science (USA).
