This paper contributes to the discussion of the compatibility of consumers' behavior in "real" life with GARP. Within expenditure panel data we observe a relatively low rate of violation (240 out of 3630 households). We show that these violations do not imply an "irrational" behavior of the...

Cet article discute de la compatibilité du comportement des consommateurs dans la vie réelle avec l'axiome GARP. A partir du panel polonais de 1987 à 1990, nous montrons que seulement 240 des 3630 ménages violent GARP. Ces violations ne semblent néanmoins pas indiquer un comportement...

We propose in this note a simple non-parametric test of Richter-rationality which is the basic definition of rationality used in choice functions theory. Loosely speaking, the data set is rationalizable in the Richter' sense if there exists a complete-acyclic binary relation that rationalizes...

The purpose of this paper is twofold. We first point out that violation of rationality axioms (SARP, GARP, WARP) do not necessarily lead to a non-rational behavior. Second, our tests of axioms SARP, GARP and WARP over a Polish panel data (1987-90) show that over the 3630 households only 240...
