We evaluate the appropriateness of regulation within the Canadian cable television industry by applying both parametric and non-parametric approachesto measure scale efficiency. Although we begin with a sample offering adequatedegrees of freedom for parametric estimation, important policy issues lead us toconsider further estimation over sub-samples. Since some of these sub-samplesare small enough that parametric models cannot guarantee reliable estimates, weobtain production characteristics non-parametrically through data envelopmentanalysis. The nonparametric results for scale efficiency support the parametricresults. We find evidence against a natural monopoly argument that might havejustified continuation of the mandated monopolization of Canadian cable televisionservice. By the end of the sample period, there were no longer substantial economiesof scale in most relevant markets.  相似文献

An algorithm is described to compute equilibria of the general economic model with incomplete asset markets, that is, of GEI. The algorithm is based on the existence of a route of zeros of a homotopy whose domain includes the price simplex and a Grassmann Manifold. This route is followed, in effect, by localizing and following diffeomorphic pieces in Euclidean space, and by relocalizing as is necessary.  相似文献

A new physical infrastructure to support activities based on communications and the transmission of information is being developed. Part of this infrastructure includes the construction of ‘intelligent’ buildings which are seen to play as important a role in improving efficiency of office workers as automation has played on the shopfloor of manufacturing industry. The location of these buildings is important. This article focuses on two types of experimental office development—neighbourhood offices and resort offices.  相似文献

This article begins with an explanation of how moral development for organizations has parallels to Kohlberg's categorization of the levels of individual moral development. Then the levels of organizational moral development are integrated into the literature on corporate social performance by relating them to different stakeholder orientations. Finally, the authors propose a model of organizational moral development that emphasizes the role of top management in creating organizational processes that shape the organizational and institutional components of corporate social performance. This article represents one approach to linking the distinct streams of business ethics and business-and-society research into a more complete understanding of how managers and firms address complex ethical and social issues.  相似文献
