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...

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...
