Summary, etc. | RésuméNous présentons un modèle à agents hétérogènes dans lequel émergent des intermédiaires marchands en concurrence avec un marché d’échanges directs entre producteurs ( search). Les intermédiaires n’augmentent pas la rapidité de l’échange ni n’assurent la qualité des biens, mais offrent à certains agents des conditions plus avantageuses que celles du marché de search. Si le coût de fonctionnement des intermédaires est suffisamment faible, des intermédiaires existent à l’équilibre, et tous les échanges sont intermédiés. Si ce coût est trop élevé, l’intermédiation n’est pas viable. Pour des valeurs intermédiaires, le marché intermédié et marché de search coexistent. L’étude du bien-être montre que l’effet principal de l’intermédiation est d’en modifier la répartition. |
520 ## - SUMMARY, ETC. | |
Summary, etc. | We present a model in which intermediaries that compete with a search market emerge. Agents are heterogenous vis à vis a production cost. They are allowed to choose both their economic activity, becoming a producer or a middleman, and their transaction strategies. Entering the intermediation activity is costly but subject to a free entry condition. The rationale for the existence of middlemen is neither the speeding up of transaction, nor the expertise of the quality of goods. By creating a market place distinct from the search market, they allow producers to direct their search. The equilibrium market structure depends on the operating cost of intermediation. If this cost is too high, intermediation is not a viable activity. If it is low enough, middlemen exist that attract all remaining producers. For intermediate values, both direct and intermediated exchange occur. Welfare analysis shows that the main effect of intermediation is to improve the situation of both high cost and low cost agents — middlemen and some of their clients — at the expense of intermediate cost agents.Classification JEL : D40, D51 |
