The Early Mathematics of Welfare
介绍了布鲁诺·德·芬内蒂在福利经济学中的贡献，他提出了同时最大值理论，并基于此批评了帕累托理论的自由放任解释，提出了社会福利函数的概念。
Bruno de Finetti (1906–1985) is well known as the founder of the subjective theory of probability. Less known is his contribution to economic theory. The article presents the contributions of de Finetti in the field of welfare economics. He advanced a new mathematical tool: the theory of simultaneous maxima. On this base, he criticized the laissez-faire interpretation of the Paretian theory and advanced the idea of a social welfare function, reflecting the debate on economic planning among Italian corporatist economists.
