This paper presents the Paretian Watershed and the fundamental theorems of welfare economics. It distinguishes the British approach (à la Kaldor-Hicks) from the American approach (à la Bergson-Samuelson) to new welfare economics. It develops the more recent domains of happiness economics, the comparative approach by Amartya Sen, and the theory of fair allocation by Marc Fleurbaey.
