Résumé en anglais

Questions relating to well-being have recently returned to the limelight, notably with the publication in September 2009 of the Stiglitz-Sen-Fitoussi commission report on the measurement of economic performance and social progress. Has this commission changed the terms of the debate on what a society's wealth and well-being are? Has it proposed new paradigms? In accepting the limitations of GDP as a key indicator of well-being, has it developed a new theoretical foundation and new evaluation criteria suited to a very different situation and to very different priorities from those that prevailed at the time when GDP first became established as a measure of national economic performance? These are the main questions raised and reviewed by this paper.
