Abstract

In this paper we present complete characterizations of the expenditure functions for both utility representations and preference structures. Building upon these results, we also establish under minimal assumptions duality theorems for expenditure functions and utility representations, and for expenditure functions and preference structures. These results apply indistinctly to finite-and infinite-dimensional spaces; moreover, in the case of preference structures they are valid for non-complete preorders.
