[eng] Emmanuelle Bénicourt - Amartya Sen: a new era for development? A response to Alexandre Bertin.. This article reviews some of the ambiguities to be found in that of A. Bertin published last year in the Revue Tiers Monde (n° 182) on the topic of Sen's capacity approach. That approach has in fact remained virtually the same since the early 1980s, and there was no break in 1987. This is followed by an outline of the similarities between Sen's concepts and those of the undp and the World Bank. Lastly, the article looks at the effects of the capacity approach on concrete analysis: neither Sen nor the international organizations apply this theoretical framework in their empirical studies.
