Wicksell's Social Philosophy and his Unanimity Rule

Wicksell saw economics as a way to effect social change. In addition to academic writings, he produced a steady stream of pamphlets, newspaper editorials, and public lectures that brought theoretical economics to bear on social policy. In this paper, consideration is given to this wider variety of Wicksell's writings, and his unanimity rule for public goods decision making is examined within the context of his social philosophy. We argue that the unanimity rule, rather than being narrowly focused on efficiency concerns, operated as a practical mechanism to achieve Wicksell's larger goal of social justice. This stands in contrast to the interpretation of Wicksell commonly presented in the public choice literature.
