This note characterizes the Weak Weak Axiom of Revealed Preference and Wald’s Weak Axiom for not necessarily differentiable demand functions. A theorem which generalizes a previous result of Kihlstrom, Mas-Colell and Sonneschein (1976) and Hildenbrand and Jerison (1989) is presented. It is also shown that the theorem cannot be extended to the set of not necessarily homogeneous demand functions. The method of proof used in this note is very simple and lends itself to an immediate geometrical interpretation; it is also shown that it can be usefully employed to obtain simpler proofs of other results found in this literature.
