Chain stability in trading networks
在双边合同的交易网络模型中，提出了链稳定性概念，证明在偏好满足联合完全替代性和总供求定律时，链稳定性等价于稳定性；在可转移效用情形下，链稳定结果与竞争均衡等价。
In a general model of trading networks with bilateral contracts, we propose a suitably adapted chain stability concept that plays the same role as pairwise stability in two‐sided settings. We show that chain stability is equivalent to stability if all agents' preferences are jointly fully substitutable and satisfy the Laws of Aggregate Supply and Demand. In the special case of trading networks with transferable utility, an outcome is consistent with competitive equilibrium if and only if it is chain stable.
