Abstract

[eng] Intermediation and markets : points to consider . The economic analysis of current regulations must be based on the differences in the nature of investments and financing by intermediation on the one hand and via the market on the other. These differences are apparent in three areas : information, risk and client relations. The financial markets function on the basis of collective information which, in principle, is shared amongst all players while intermediation requires access to private data. Moreover, intermediation means the risk is shared whilst the opposite applies to the market. Lastly, although market relations are impersonal, intermediation is a two-way partnership that comes with all of the problems of a principal/agent relationship. . Classification JEL : G10, G20 [fre] L’analyse économique de la réglementation doit se fonder sur les différences de nature entre placement et financement par l’intermédiation d’une part, le marché d’autre part. On relèvera ces différences dans trois domaines : l’information, le risque, la relation avec la clientèle. Le fonctionnement du marché financier repose sur la mise à disposition d’une information collective, en principe également partagée par tous les acteurs, alors que l’intermédiation relève d’une information privative. De même, l’intermédiation mutualise le risque tandis que le marché le démutualise. Enfin, alors que la relation de marché est impersonnelle, la relation d’intermédiation est bilatérale et pose tous les problèmes de la relation principal-agent. . Classification JEL : G10, G20
