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

Recent technological developments have transformed the cable television industry (CATV) from a simple re-transmitter of terrestrial broadcasting to a provider of a broader-band information infrastructure. With cable operators facing an undesirable market situation while operating a fiber optics network vital to the creation of an information-based society within Japan, the Japanese Government has introduced several supportive measures for the industry. Such governmental intervention should desirably be justified not only from a political viewpoint but also from an economic one; otherwise such measures may distort economic efficiency. In this article, using Data Envelopment Analysis (DEA), the authors identify the deficiencies of an accounting-based intervention scheme and propose an alternative framework with no disincentive side effects.  相似文献

The experience of Chinese Taipei shows that opening up a previously protected market to new entrants can be a more effective and reliable way to enhance competition than regulating the behavior of dominant or monopolistic firms. Moreover, when opening up the market, the liberalizing measures adopted by government should be market-structure-neutral. That is, it should not try to dictate the direction and results of market competition. A more pressure-resistant mechanism should be designed to deal with market power, taking the form of a regime that is cross-sector, independent and collective in its decision-making, such as has been the case with Chinese Taipei's Fair Trade Commission.  相似文献

Today telex and cable are two important means usod in communication with customors abroad. In telex,as it is not chargod by the number of words but by the minute,more words can be used to express our idea,so it is less difficult for our students to learn,while in cable we,in order to save money,  相似文献

In an industry with upstream economies of scale in the distribution of differentiated products to retailers which have monopoly power within separate local market areas, the retailers have an incentive to exert monopsony power due to the divergence between average and marginal costs in the distribution of those inputs. The retailers increase their ability to exert monopsony power by forming coalitions (that is, chains) across local markets. Sufficiently large retail chains may force input price below the seller's average cost, thus ‘free riding’ on the level of product variety supported by other retailers. Vertical integration, cartels, or other cooperative behavior, however, can be means to control the level of product variety, and may increase both industry profits and economic welfare. Policy applications to the cable television, motion picture, and pharmaceutical industries are discussed.  相似文献

As broadband use has grown over the past few years, scholars and policymakers have turned some of their attention to the urban-rural broadband divide. While existing research offers important insights into this divide, no research has fully explored the differences in broadband deployment patterns among various types of telecommunications providers, including both large and small telephone and cable providers. Through data collected from interviews with telecommunications company representatives, this research assesses the extent to which different types of providers are deploying broadband in urban and rural areas. The interviews are also used to ascertain factors shaping the broadband deployment decision-making process for different types of providers. Both the quantitative and qualitative elements of this research demonstrate clear patterns among different types of providers in relation to rural broadband deployment, as different types of companies are influenced by somewhat unique regulations, competitiveness concerns, resource levels, and existing infrastructure conditions.  相似文献
