The Law of One Price (LoOP) states that all firms face the same prices for their inputs and outputs in the competitive market equilibrium. This law has powerful implications for productive efficiency analysis, which have remained unexploited thus far. This paper shows how LoOP-based weight...

We discuss the nonparametric approach to profit efficiency analysis at the firm and industry levels in the absence of complete price information, and propose two new insights. First, choosing one commodity (whose price is known) as a numeraire good enables us to measure profit inefficiency in...

We present the revealed preference conditions that characterize the data sets that are consistent with the maximization of a weakly separable utility function. We show that verifying these revealed preference conditions is np-hard. We also present an integer programming approach, which is...

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

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...

We review a nonparametric "revealed preference" methodology for analyzing collective consumption behavior in practical applications. The methodology allows for accounting for externalities, public consumption, and the use of assignable quantity information in the consumption analysis. This...

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...
