[fre] Le résultat de Diamond 1971 montre que ta tarification en concurrence imparfaite se modifie de fa on spectaculaire on introduit une imperfection dans information des consommateurs objet de cet article est de faire le point sur les travaux qui explorent cette piste dans un contexte de produits différenciés et expliquer pourquoi un tel contexte est particulièrement approprié pour étudier impact de activité de collecte information des consommateurs sur la concur rence De plus la prise en compte de imperfection de information des consom mateurs permet apporter un éclairage nouveau sur la théorie des marchés avec produits hétérogènes. [eng] The result found by Diamond [1971] shows that imperfect information on thé consumer side drastically affects pricing on imperfectly competitive markets. This paper aims at summing up the literature that follows this route in a differentiated products context and to show that such a context is very appropriate to study the impact of consumer search on competition. Furthermore, taking into account imperfect consumer information sheds new light on the theory of markets for hete­rogeneous products.
