论文摘要
基于双边（不可分割）合同的交易可以由网络代表。顶点对应于代理，而弧表示双边合同的非价格要素。给定每个弧的价格，代理商选择最大化其效用的事件弧。我们扩大该模型，以允许在可能交易的一组合同上进行多功能限制，这些合同可以解释为建模有限的一个for One替代。我们表明，对于双面市场，存在竞争均衡，但是对于多面市场而言，这可能是不可能的。
Trades based on bilateral (indivisible) contracts can be represented by a network. Vertices correspond to agents while arcs represent the non-price elements of a bilateral contract. Given prices for each arc, agents choose the incident arcs that maximize their utility. We enlarge the model to allow for polymatroidal constraints on the set of contracts that may be traded which can be interpreted as modeling limited one for-one substitution. We show that for two-sided markets there exists a competitive equilibrium however for multi-sided markets this may not be possible.
