项目摘要

In the paper "Cournot competition and access pricing in regulated industries" we analyzed the equilibrium of an economy where one of the producers in the final market is the monopolistic supplier of input needed by both its owner and competitors, and monopoly pricing behavior of the firm is regulated. Two major objectives of this paper are (i) to study how high should the price of the entrant's final product be compared with the marginal cost of the upstream supplier, and in relation to it, (ii) to examine Baumol-Willig efficient component pricing rule (ECPR) which states that the access charge should be set roughly by the formula : optimal access charge=direct cost of providing access+opportunity cost of providing access.The problem has been studied in various settings. We were concerned with the case where the quality of the monopolist's product may be different from the entrants'. We also studied case where entrants act as Cournot oligopolists as well as the case where they behave as price takers. We do not assume, to begin with, that profits of downstream firms are zero as most previous studies did. We discussed how our analysis relates to the known results in the literature.In the accompanying paper "On the measurement of welfare changes at second best optima" we derived formulae for the change in the welfare caused by the relaxation of the distortionary constraint of the model.

在论文“古诺竞争和管制行业的准入定价”中，我们分析了一个经济体的均衡，其中最终市场上的一个生产者是其所有者和竞争者都需要的投入的垄断供应商，并且该企业的垄断定价行为受到管制。本文的两个主要目标是（i）研究进入者的最终产品的价格应该与上游供应商的边际成本相比有多高，以及与之相关的，（ii）研究Baumol-Willig有效成分定价规则（ECPR），该规则规定接入费应该大致由以下公式确定：最优接入费用=提供接入的直接成本+提供接入的机会成本。我们关注的是垄断者的产品质量可能与进入者的产品质量不同的情况。我们还研究了进入者作为古诺寡头以及价格接受者的情况。开始，我们并不像以前的大多数研究那样假设下游企业的利润为零。我们讨论了我们的分析如何与文献中的已知结果相联系。在所附的论文“关于次优福利变化的测量”中，我们推导了由模型的扭曲约束的放松引起的福利变化的公式。
