The Revealed Preference Approach to Collective Consumption Behavior : Testing, Recovery and Welfare Analysis

Cherchye, L.; De Rock, Bram; Vermeulen, Frederic - 2021

We extend the nonparametric 'revealed preference' methodology for analyzing collective consumption behavior (with consumption externalities and public consumption), to render it useful for empirical applications that deal with welfare-related questions. First, we provide a nonparametric...

Is Utility Transferable? A Revealed Preference Analysis

Cherchye, L. - 2011

We provide a revealed preference analysis of the transferable utility hypothesis, which is widely used in economic models. First, we establish revealed preference conditions that must be satisfied for observed group behavior to be consistent with Pareto efficiency under transferable utility....

Generating Random Optimising Choices

Heufer, Jan - 2012

Generalised Axiom of Revealed Preferences (GARP), that is, they are consistent with utility maximisation. The choices are drawn … from an approximate uniform distribution on the admissible region on each budget which ensures consistency with GARP, based … it can be used to approximate the power of tests for conditions for which GARP is a necessary but not sufficient …

Homothetic efficiency and test power : a non-parametric approach

Heufer, Jan; Hjertstrand, Per - 2015

We provide a nonparametric revealed preference approach to demand analysis based on homothetic efficiency. Homotheticity is a useful restriction but data rarely satisfies testable conditions. To overcome this we provide a way to estimate homothetic efficiency of consumption choices. It...

Homothetic efficiency : a non-parametric approach

Heufer, Jan; Hjertstrand, Per - 2014

This article provides a robust non-parametric approach to demand analysis based on a concept called homothetic efficiency. Homotheticity is a useful restriction or assumption but data rarely satisfy testable conditions. To overcome this problem, this article provides a way to estimate homothetic...

Consistent subsets : computationally feasible methods to compute the Houtman-Maks-index

Heufer, Jan; Hjertstrand, Per - 2014

We provide two methods to compute the largest subset of a set of observations that is consistent with the Generalised Axiom of Revealed Preference. The algorithm provided by Houtman and Maks (1985) is not comput ationally feasible for larger data sets, while our methods are not limited in that...

Quasiconcave Preferences and Choices on a Probability Simplex – A Nonparametric Analysis

Heufer, Jan - 2010

A nonparametric approach is presented to test whether decisions on a probability simplex could be induced by quasiconcave preferences. Necessary and sufficient conditions are presented. If the answer is affirmative, the methods developed here allow to reconstruct bounds on indifference curves....
