Herzberg [12] constructed a representative\r\nutility function for finite-dimensional social decision problems and\r\nsince the decision problems of macroeconomic theory are typically\r\ninfinite-dimensional, Herzberg's original result is insufficient for many\r\napplications. We therefore generalise his result by allowing the social\r\nalternatives to belong to a general reflexive Banach space and provide\r\nsufficient conditions for our new results to be satisfied in economic\r\napplications.","lang":"eng"}]}]
