摘要
In a competitive dynamic durable good market where sellers have private information about quality, I identify certain inefficiencies that arise due to heterogeneity in buyers' valuations. Even if the market induces dynamic sorting among sellers and all goods are eventually traded, inefficiency can arise because high valuation buyers buy early when low-quality goods are sold, while high-quality goods are allocated to low valuation buyers that buy later. This misallocation adds to the inefficiency caused by delay in trading. Under certain circumstances, high-quality goods may never be traded as in a static market. Resume Triage dynamique dans les marches de biens durables quand il y a heterogeneite des acheteurs. Dans un marche concurrentiel et dynamique de biens durables oU les vendeurs ont de l'information privee sur la qualite, l'auteur identifie certaines inefficacites attribuables a l'heterogeneite dans les evaluations des acheteurs. Meme si le marche declenche un tri dynamique entre les vendeurs et que tous les biens sont vendus, l'inefficacite peut emerger parce que les acheteurs qui valorisent le plus le bien achetent tot, quand les biens de basse qualite sont vendus, alors que les biens de haute qualite sont ecoules plus tard a des acheteurs qui valorisent moins le bien. Cette mauvaise affectation ajoute a l'inefficacite causee par le retard a transiger. Dans certaines circonstances, les biens de haute qualite peuvent ne jamais etre transiges comme dans un marche statique.
