TY - GEN AB - This paper applies microeconomic foundations to construct a \representative agent". Herzberg [12] constructed a representative utility function for finite-dimensional social decision problems and since the decision problems of macroeconomic theory are typically infinite-dimensional, Herzberg's original result is insufficient for many applications. We therefore generalise his result by allowing the social alternatives to belong to a general reflexive Banach space and provide sufficient conditions for our new results to be satisfied in economic applications.
