Trading in Networks: Theory and Experiments
研究网络中的定价模型，将市场势力、竞争和双重边际化等传统概念映射到网络中，通过理论和实验揭示节点关键性对定价、效率和剩余分配的影响。
We propose a model of posted prices in networks. The model maps traditional concepts of market power, competition, and double marginalization into networks, allowing for the study of pricing in complex structures of intermediation, such as supply chains, transportation and communication networks, and financial brokerage. We provide a complete characterization of equilibrium prices. Our experiments complement our theoretical work and point to node criticality as an organizing principle for understanding pricing, efficiency, and the division of surplus in networked markets.
