Afriat's Theorem for Indivisible Goods
Forges, Francoise; Iehlé, Vincent - CESifo - 2013

Goodness of fit in optimizing consumer's model
Alcantud, José Carlos R.; Matos, Daniel L.; Palmero, … - Volkswirtschaftliche Fakultät, … - 2009
We provide two new indices of efficiency for determining the degree of coherence in an agent's consumption decisions. We analyze to which extent they improve the efficiency displayed by Varian's (Journal of Econometrics, 1990) index. We report on the results of a Montecarlo experiment that...

Two New Proofs of Afriat's Theorem
Scarf, Herbert E.; Fostel, Ana; Todd, Michael J. - School of Management, Yale University - 2004
We provide two new, simple proofs of Afriat's celebrated theorem stating that a finite set of price-quantity observations is consistent with utility maximization if, and only if, the observations satisfy a variation of the Strong Axiom of Revealed Preference known as the Generalized Axiom of...

Afriat's theorem for general budget sets
Forges, Françoise; Minelli, Enrico - Université Paris-Dauphine (Paris IX) - 2009
Afriat proved the equivalence of a variant of the strong axiom of revealed preference and the existence of a solution to a set of linear inequalities. From this solution he constructed a utility function rationalizing the choices of a competitive consumer. We extend Afriat's theorem to a class...
