研究了两种将通信成本作为交易成本的模型。一种模型着眼于沟通在确定企业使用当地要素服务的地理范围方面的作用。通信成本被建模为准公共物品网络，其中通信服务由平均成本定价垄断者提供。网络技术受到收益递增、拥塞效应和网络外部性的影响。第二个模型侧重于国际货物贸易目的的通信，对通信技术的假设与第一个模型类似。在该模型中，国际均衡和全球均衡之间存在重要区别。在这两个模型中，都考察了通信成本降低对企业市场范围、贸易量和生产率的影响。这些模型具有通用的多重均衡，具有截然不同的福利和相对静态特性。
Two models in which communication costs are a cost to trade are investigated. One model looks at the role of communication in determining the firms' geographic extent in the use of local factor services. Communication costs are modelled as a quasi-public-good network in which communication services are provided by an average cost-pricing monopolist. The network technology is subject to increasing returns, congestion effects, and network externalities. The second model focuses on communication for the purposes of international trade in goods with similar assumptions on the technology of communication as in the first model. In this model an important distinction is made between international equilibrium and global equilibrium. In both models the impact of reductions in communication costs on the market extent of firms, trade volumes, and productivity are examined. The models have generic multiple equilibria with quite different welfare and comparative static properties.
