Paretian Welfare Judgements and Bergsonian Social Choice
识别了新福利经济学中补偿原则学派与伯格森-萨缪尔森学派综合的逻辑条件，对研究福利判断和社会选择的经济学者有参考价值。
Two distinct approaches can be identified in the new welfare economics. The school of thought based on the compensation principles attempted to see what can be said about social welfare without making interpersonal comparisons of well‐being by extending the applicability of the Pareto principle through hypothetical compensatory payments between gainers and losers. The Bergson‐Samuelson school of thought introduced the social welfare function as a formal method of introducing a Pareto‐inclusive ethical belief on social welfare, whose policy implications we should theoretically explore. Synthesising these two approaches, this paper identifies a condition under which the new welfare economics is logically impeccable.
