Competition in Exchanges and Reputational Concerns

Abstract

Cet article propose un modèle théorique qui analyse l?impact de la compétition sur la qualité de certification menée par la bourse. Dans le cas où celle-ci certifie honnêtement la qualité des nouvelles émissions, la bourse ne coterai que les bons projets, ce qui permettrait d?atténuer l?assymétrie d?information et de générer des gains à travers les transactions. Cependant, il se peut qu?il soit plus profitable pour la bourse d?être laxiste sur les critères de cotation. En effet, l?enjeu entre les profits à court terme et la réputation conduit à un comportement stratégique de la bourse. Les résultats montrent que le fait de surévaluer la qualité d?un projet est un équilibre, quel que soit le risque pour la réputation. Contre-intuitivement la compétition entre les bourses conduit à un comportement plus laxiste qu?en situation de monopole et réduit le bien-être tant que la réputation du concurrent est plus élevée que celle de la bourse en monopole.
