Abstract

We study the testable implications of normal demand in a two-goods setting. For a finite dataset on prices and quantities, we present the revealed preference conditions for normality of one or both goods. Our characterization provides an intuitive extension of the well-known Weak Axiom of Revealed Preference, and is easy to use in practice. We illustrate the empirical relevance of our theoretical results through an application to the experimental dataset presented in Andreoni and Miller (2002).
