L'impact des options extérieures sur les échanges en information asymétrique

Bruno Jullien and Claude Jessua

Revue Économique, 1996, vol. 47, issue 3, 437-446

Abstract: [eng] The paper studies the optimal contract offered by a buyer to a producer, under asymétrie information on both the marginal cost and the fixed cost. The model illustrates the results obtained when generalizing the adverse selection Principal-Agent model by relaxing the assumptions on outside options. Asymétrie informa­tion can reduce or increase the volume of trade. The informational rent is not monotonie. Quantity distortions relate to the shape and the curvature of the func­tion linking the fixed cost to the marginal cost. [fre] Nous étudions le contrat optimal offert par un acheteur à un producteur qui dispose d'une information privée sur son coût marginal et son coût fixe. Ce modèle illustre les résultats qui apparaissent lorsqu'on généralise le modèle Prin­cipal-Agent de sélection adverse en relâchant les hypothèses sur les options exté­rieures. L'information asymétrique peut réduire ou augmenter le volume des échanges. La rente d'information n'est plus monotone. Les distorsions dépendent de la pente et de la courbure de la relation liant le coût fixe au coût marginal.
