Abstract

The ?Elimination by aspects? (eba) heuristic is used to choose among a given set of products during a sequential process : at each stage, consumers eliminate the products which do not possess a particular attribute, until only one good remains. Tversky [1972] elaborates a discrete choice model from this heuristic, in which the price gap is seen as an attribute. We use these probabilities to construct demands of a differentiated duopoly with imperfect rationality of consumers. At the price equilibrium, the ?differentiation by attributes? constitutes a general framework which embodies both horizontal and vertical differentiation. Classification JEL : D11, D43, L13.
