我们认为一个中间商网络促进买卖双方之间的交易。中介交易者面临着私人交易成本,网络表征了可行交易的集合,拍卖机制设定了价格。我们研究稳定和平衡网络。稳定的网络,这是强大的代理人的合谋行为,存在时,成本的不确定性是严重的,多个,独立的交易关系是有价值的。自由进入过程决定了平衡网络的形成。这种网络的特点是相对于最优市场组织而言中介机构太少,而且它们呈现出不对称的结构,放大了关键中介机构所经历的冲击。研究了稳定网络和均衡网络的福利和经验意义。
We consider a network of intermediaries facilitating exchange between buyers and a seller. Intermediary traders face a private trading cost, a network characterizes the set of feasible transactions, and an auction mechanism sets prices. We examine stable and equilibrium networks. Stable networks, which are robust to agents’ collusive actions, exist when cost uncertainty is acute and multiple, independent trading relationships are valuable. A free-entry process governs the formation of equilibrium networks. Such networks feature too few intermediaries relative to the optimal market organization and they exhibit an asymmetric structure amplifying the shocks experienced by key intermediaries. Welfare and empirical implications of stable and equilibrium networks are investigated.
