This paper analyzes the networking aspect in telecommunication services and the recent divestiture and increased competitiveness of the industry. The product considered is the right to access the network. The utility of a consumer from having access to a network depends on the network's quality, defined by the number of other local and long-distance consumers which can be reached. Network services are provided in two layers; On the lower layer consumers within a local access and transport area (LATA) are connected to a central office which provides the basic switching facility for local telecommunication. On the upper layer, LATAs are connected together by an interLATA carrier, to enable long distance communication from different localities.It is shown that relative to the choices of an unconstrained monopolist, larger networks at both layers may be obtained by imposing quality controls, while price controls may have the opposite effect. A divestiture policy in which all local carriers are connected to a single long distance carrier is likely to reduce the quality of services at both layers. Introducing competition among long-distance carriers further reduces the quality of long distances services but may improve the local service. 相似文献

This paper develops a framework for the optimal choice of exchange rate bands within an environment in which policymakers dislike nominal exchange rate variability, but value the flexibility to adjust the nominal exchange rate in response to shocks, in order to attain real exchange rate objectives. The paper provides an endogenous characterization of the optimal exchange rate band in terms of the underlying distribution of shocks to the current and capital accounts of the balance of payments and in terms of the commitment reputation of policymakers. 相似文献
