In this study I explored the effects of the development of direct competition in the delivery of cable services to a small Arkansas city. The emergence of competition produced lower prices, better customer service, increased choices in programming, and technological improvements as the market structure moved from monopoly to duopoly and achieved an equilibrium in which each service company serves a 50% market share. Because neither firm is producing a profit under the current situation, I argue that in the long-run the competitors may switch to oligopolistic pricing behavior and focus on nonprice competition in an effort to achieve profitability. 相似文献

This article reviews the recent mergers among multiple-system operators (MSOs), investigates their impact on market concentration, and examines cable multiple ownership rules as well as antitrust applications. The implication of telephone company (telco) entry is then discussed. It was concluded that the exhibition stage of the cable industry is currently moderately concentrated but has reached its highest degree in 20 years. The wave of mergers shifted from the high profile telco-MSO strategic alliances to the major MSOs' consolidations aimed at building efficient market clusters. The trend of market concentration is expected to continue given the current economic and regulatory climate. 相似文献

Local television news markets have been defined in terms of oligopoly theory, in which the number of competitors is limited and firms must pay significant attention to pricing behavior and product differentiation. The author explores how the development of independent television stations, cable television, and video recorders is changing the market from oligopoly to monopolistic competition. 相似文献

This article investigates the issue of the relation between market competition and programming diversity in Taiwan's TV market. For more than 20 years, Taiwan's TV market had an oligopolistic structure with 3 networks dominating the market. With the popularity of satellite TV during the 1990s, the oligopoly rapidly ended. This study examines how programming diversity was affected by the changing TV market structure in Taiwan. Programming diversity was measured by 3 methods using program data from the 3 networks operating in Taiwan: vertical programming diversity, horizontal programming diversity, and prime-time programming strategies. The results indicate a negative relation between market competition and programming diversity. Although the market competition increased from 1986 to 1996, this study discovered that the degree of programming diversity was reduced year by year. 相似文献

Summary The legal publishing industry has experienced waves of acquisition and consolidation, with almost all of the established players becoming affiliated with either Thomson or Reed Elsevier. A widespread assumption is that this consolidation is driving out the smaller participants in the market, especially in conjunction with the expansion of free Web sites for primary source material. It is presumed that the entrepreneurs who have smaller, profit-based companies are becoming less interested in the market due to financial pressures, increased difficulty of capturing market share, and threat of acquisition (friendly or hostile). In order to confirm or refute this assumption, the author reviews the industry consolidations, describes the delineation of representative small legal publishers, and analyzes their responses to questions about how the recent industry changes have affected their strategies, markets and product lines. The resulting picture is of an environment much different than that painted by current media pundits. Contrary to the presumption of a disappearing landscape of small players, there is a positive perception of “ripe opportunity” pushing companies into this marketplace-companies armed with new technology tools and strong convictions that they can reach customers ready and willing to do old business in new ways. The small publishers seem to be weathering the climactic industry changes, and have expectations of growth and expansion. 相似文献

期权以客观收益和实际效用为依据对商品定价,保证期权人在市场有利时获得更多收益,在市场不利时减少损失,特别适用于不完全、不确定的市场.信息市场是典型的垄断竞争市场,期权有助于制定更合理的信息商品价格,能够提高信息市场运作的效率,因此在信息资源配置中引入期权理论具有一定的意义.文章首先分析了期权理论对于信息资源配置的适用性以及信息资源的期权价格,然后探讨了期权价格配置模型,并在此基础上进行了一个实例分析. 相似文献

This study examines certain changes made within the Russian newspaper industry both before and after the political transformations occurring in the former Soviet Union. Although these changes began after Gorbachev came to power, the most dramatic changes took place after the collapse of the Soviet Union. The political economy perspective provides a useful means to explain the relation between these socioeconomic transitions and the newspaper industry. Since the failed coup of August 1991, the Russian media have attempted to adapt to conditions persistent with the free market economy. As a result of the free market economy, the Russian newspaper industry currently tends to depend on advertising revenue for survival. 相似文献

The pharmaceutical industry produces an abundance of special‐purpose knowledge, flooding the markets it is most interested in. To gain the largest scientific impact and market value from research, drug company articles placed in medical journals are often written under the names of independent medical researchers. Pharmaceutical company statisticians, reviewers from a diverse array of company departments, medical writers, and publication planners are only rarely acknowledged in journal publications, and key company scientists only sometimes acknowledged. The public knowledge that results from this ghost‐managed research and publication is a marketing tool, providing bases for continuing medical education, buttressing sales pitches, and contributing to medical common sense and further research. In the pharmaceutical industry, knowledge is a resource to be accumulated, shaped, and deployed to best effect. In this paper, I describe this process and discuss ways in which it might be addressed. 相似文献

This article discusses European Community policy as it relates to information technology and the information industry. With the advent of a common market within Europe there is an increase in competition and the removal of national barriers. This process is slow and difficult to accomplish and is not yet complete. Markets have traditionally been fragmented by linguistic differences, as well as different standards and laws. An EC policy towards information and information technology industries has evolved since the 1960s. This policy has steered a difficult course between protectionism and liberalization. It is unclear whether or not the common European market will be sufficient on its own to foster a competitive information market and information technology industry. The European Commission has traditionally taken an interventionist role. In the field of EC information law many, but by no means all. issues have been confronted. The Commission's role is changing from giving significant grants for collaborative European research and development towards incentives to companies to increase their own research and development spending, and towards building information infrastructure. 相似文献
