We provide a nonparametric 'revealed preference' characterization of rational household behavior in terms of the collective consumption model, while accounting for general (possibly non-convex) individual preferences. We establish a Collective Axiom of Revealed Preference (CARP), which provides...

The transferable utility hypothesis underlies important theoretical results in household economics. We provide a revealed preference framework for bringing this (theoretically appealing) hypothesis to observational data. We establish revealed preference conditions that must be satisfied for...

We reconsider the motivation of Data Envelopment Analysis (DEA), the non-parametric technique that is widely employed for analyzing productive efficiency in academia, the private sector and the public sector. We first argue that the conventional engineering motivation of DEA can be problematic...

We develop a novel framework to analyze the structural implications of the marriage market for house-hold consumption patterns. We start by de…ning a revealed preference characterization of e¢ cient householdconsumption when the marriage is stable. In particular, stability means that the...

We conducted an experiment to collect data on consumption decisions made by children of different age categories. In particular, our experiment involves unsophisticated discrete consumption choices,and we present a rationality test that is specially designed for the resulting choice data. Our...

We present necessary and sufficient revealed preference conditions to verify whether a finite data seton nonlinear budget sets is consistent with the maximization of a quasi–concave utility function. Ourresults can be used to test for convexity of the underlying preference relation. We also...

We present necessary and sufficient revealed preference conditions to verify whether a finite data set on nonlinear budget sets is consistent with the maximization of a quasi-concave utility function. When budget sets are finite unions of polyhedral convex sets, these conditions require...
