Title: The Weak Axiom of Revealed Preference and Homogeneity of
Demand Functions
Abstract: We characterize (a weak version of) the Weak Axiom of Revealed
Preference for demand functions which are not necessarily homogenous.
We relate this property to the validity of the Weak Axiom and to the
negative semidefiniteness of the Slutsky substitution matrices. In
particular, it is shown that the weak Axiom implies homogeneity.
