We derive necessary and sufficient conditions for a finite data set of price and demand observations to be consistent with an additively separable preference. We do so without imposing concavity on any of the subutility functions or convexity of the budget set a priori, thereby generalizing...

Consider a finite data set where each observation consists of a bunde of contingent consumption chosen by an agent from a constraint set of such bundles.  We develop a general procedure for testing the consistency of this data set with a broad class of models of choice under risk and under...

This paper is largely motivated by the empirical observation that GP visits per person under the NHS have increased in England since the mid-1970s, while list sizes have decreased over the same period  A hypothesis consistent with this observation is that larger list sizes are associated with...

This paper compares the goods and characteristics models of the consumer within a non-parametric revealed preference framework. Of primary interest is to make a comparison on the basis of predictive success that takes into account dimension reduction. This allows us to nonparametrically identify...

This paper presents a nonparametric analysis of intertemporal models of consumer choice that relax consumption independence. We compare the revealed preference conditions for the intertemporally nonseparable models of rational habit formation and rational anticipation. We show that these models...

Consider a finite data set where each observation consists of a bundle of contingent consumption chosen from a constraint set of contingent consumption bundles. We develop a general procedure for testing the consistency of such a data set with a broad class of models of choice under risk or...
