Afriat in the Lab
Heufer, Jan; van Bruggen, Paul - 2016
Varian (1988) showed that the utility maximization hypothesis cannot be falsified when only a subset of goods is observed. We show that this result does not hold under the assumptions that unobserved prices and expenditures remain constant. These assumptions are naturally satisfied in laboratory...

A Geometric Measure for the Violation of Utility Maximization

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 …

A Comment on Revealed Preference with a Subset of Goods
van Bruggen, Paul - 2016
Varian (1988) introduced an important proposition regarding restrictions on consumption data if observations of the quantities of a good are missing. In this paper, a simple counterexample is presented to show that the original proof is incorrect, and a new proof is provided. The new proof is...

Power against random expenditure allocation for revealed preference tests
Hjertstrand, Per - 2019
This paper proposes new power indices for revealed preference tests. The indices are based on a model of irrational consumption behavior where the consumer randomly allocates a certain fraction of expenditure. The methods allow a researcher to trace out the entire power curve against random...

The measurement of child costs : a rothbarth-type method consistent with scale economies
Bargain, Olivier; Donni, Olivier - 2009
We propose a new methodology to estimate the share of household income accruing to children (i.e., the cost of children). Following the principle of the Rothbarth approach, the identification of the children's share requires the observation of at least one adult-specific good. However, our...

The measurement of child costs : evidence from Ireland
Bargain, Olivier; Donni, Olivier; Gbakou, Monnet - 2009
We apply an extension of the Rothbarth approach to estimate the share of household resources accruing to children (i.e., the cost of children) in Ireland. The method also allows us to identify the economies of scale in the household and indifference scales in Lewbel (2003)’s sense. A practical...
