Vertical Ownership,Program Network Carriage,and Tier Positioning in Cable Television: An Empirical Study

Using a 2004 cross-sectional database of digital cable systems in the U.S., we provide new evidence that the effects of vertical ownership ties between systems and programming suppliers persist in spite of extensive channel capacity expansion, as well as new competition from direct broadcast satellites. Focusing on four program network groups (basic outdoor entertainment, basic cartoon, basic movie, and premium movie), we generally find that integrated cable systems carry their affiliated networks more frequently and carry unaffiliated rival networks less frequently—a pattern identified by previous studies using data prior to DBS or the capacity expansion effects of digital cable. We also find that integrated systems that do carry rival networks often position them on digital tiers having more limited subscriber access, a pattern not investigated in previous studies.     

Short‐Time Compensation as a Tool to Mitigate Job Loss? Evidence on the U.S. Experience During the Recent Recession

During the recent recession only seventeen states offered short‐time compensation (STC)—prorated unemployment benefits for workers whose hours are reduced for economic reasons. Federal legislation passed in 2012 will encourage the expansion of STC. Exploiting cross‐state variation in STC, we present new evidence indicating that jobs saved during the recession as a consequence of STC may have been significant in manufacturing, but that the overall scale of the STC program was generally too small to have substantially mitigated aggregate job losses in the seventeen states. Expansion of the program is necessary for STC to be an effective countercyclical tool in the future.     

中国天然气价格困局——天然气价格改革思考之一

中国天然气价格采用国家控制下的供应推动型顺价机制,建立在单一气源产业链模型基础上,分段管理,是基于平均成本和合理利润的政府定价。这一机制有效运行的两个基础条件是天然气产业比较简单和计划经济体制主导经济运行。产业规模快速扩大、同一市场多气源供气、供气主体复杂化、供气管道网络化、全国市场一体化、需求主体分散化的天然气产业新格局导致现行天然气价格体制有效运行的基础条件不复存在,由此使我国天然气产业在快速发展中产生重重矛盾。这些矛盾包括:产业规模快速扩大的趋势给政府定价增加技术难度;同一市场多气源在顺价机制下必然导致市场价格多轨;供气管道网络化趋势成为天然气顺价机制的最大技术障碍;供气主体复杂化趋势导致利益调节不均衡和越来越困难;气源加权平均定价严重阻碍天然气产业发展;全国市场一体化将彻底颠覆资源属地化和区域性的限制;天然气消费主体分散化趋势使计划经济条件下行政配置资源的做法难度加大。     

一种辅助工程项目投标决策ANN方法

工程项目投标决策问题不确定性较强，受决策者主观意志影响较大，如果施工单位不加选择地盲目投标，势必会给企业生产经营带来混乱，并且造成极大的浪费。借助于有效利用企业历史投标数据的理念，提出了一种基于人工神经网络（ANN）的量化计算方法，通过构建BP神经网络模型对企业历史投标数据进行信息挖掘，进而对拟投标项目进行评估预测，可以较好地解决由于决策者主观影响带来的决策失误问题。通过实例阐述了利用MATLAB编程进行计算的过程。     

The institutional environment and effects of telecommunication privatization and market liberalization in Asia

Are the privatization and market competition models resulting in the leveling of the supply-side playing field, and are they demand driven as expected? Quantitative indicators of network expansion and efficiency provide a partial and inconclusive picture. Instead, an evolutionary property rights framework is favored. Examined in detail are the institutional environments that lead to particular types of property rights which in turn affect network expansion and efficiency. The article offers two conclusions: (a) introducing market competition is slow, messy and difficult to manage but, where present, it is better for growth than privatization alone, and (b) network expansion and efficiency are most noticeable where adequate property rights and enforcement mechanisms are in place. It also conjectures that the “East Asia Model” toward network expansion may not be easily generalizable.     

Development of educational program for production manager leading new perspectives on manufacturing technology

In this paper, we consider the problems associated with the development and management of an educational program for manufacturing managers in leadership roles who are making contributions towards the creation of customer delight as well as customer satisfaction using manufacturing technology. The basic concept combines an intelligent knowledge-based approach with the kaizen activity program within the framework of value creation and comparative advantage models based on a network referred to as Academia, Business, Consultancy, and Government (ABC-G). This educational program, which reflects the characteristics of manufacturing technologies and practices in the Hokuriku District of Japan, was developed in 2005–2006 and the trial education was developed in 2005 and 2006, and a trial run of this program was conducted in 2006 and 2007 in close collaboration with local manufacturing companies and their employees. The results are informative of the effects of educating manufacturing managers in Japan and the problems that will have to be overcome for the continuous improvement of the program.     

Personal computer networks

In this discussion of the growth of personal computer use in the USA, and the increasing interest in linking these computers into networks, the author describes the expansion of personal computing in the USA since 1975, and cites a number of estimates, surveys, and market research studies concerning projected growth. The activities of the Personal Computer Network (PCNET) are discussed, from its founding in May 1977 to initial experimental operation in early 1978. A number of options for network link media are dealt with, including the dial telephone system and various radio link designs. These various network architectures lead to several policy issues: How will the standards for telephone system use interact with increasing use of personal computer-based telecommunications? How will the cost of telephone service (particularly off-peak hour rates) influence the growth and use of personal computer networks? Could, and should, the telephone carriers and/or the value-added carriers offer a packet-switched service to residential subscribers? What current restrictions are faced by personal computer users in networking via CB and amateur radio? Bandwidth for digital block radio can materially improve the cost-effectiveness of personal computer network activity — what frequencies would be suitable, and what usage restrictions would be appropriate? What are the societal consequences of personal computer networks?     

Telecommunications in the land of the Thunder Dragon: recent developments in Bhutan

This paper charts the development of telecommunications in Bhutan. Since the introduction of telecommunications services in 1963 Bhutan has faced many challenges as it has sought to roll out a network that covers the whole population and country. A small population, a mountainous geography, a transitional economy and a unique approach to development—Gross National Happiness—present many challenges that need to be overcome if the telecommunications industry is to develop further. Added to this is the decision of Bhutan to join the outside world through membership of the ITU, APT and WTO that has added liberalisation and privatisation to the challenges faced by Bhutan. This paper identifies two broad policy options that Bhutan could adopt—network expansion nationally or investment concentration towards urban areas. The authors conclude that due to the limited resources available to Bhutan these policies are contradictory and will take the telecommunications industry in quite different directions if adopted.     

Network effects,aftermarkets and the Coase conjecture: A dynamic Markovian approach

This paper investigates the expansion of the network of a monopolist firm that produces a durable good and is also involved in the corresponding aftermarket. We characterize the Markov Perfect Equilibrium of the continuous time dynamic game played by the monopolist and the forward-looking consumers, under the assumption that consumers benefit from the subsequent expansion of the network. The paper contributes to the theoretical discussion on the validity of the Coase conjecture, analyzing whether Coase's prediction that the monopolist serves the market in a “twinkling of an eye” remains valid in our setup. We conclude that the equilibrium network development may actually be gradual, contradicting Coase's conjecture. We find that a necessary condition for such a result is the existence of aftermarket network effects that accrue (at least partly) to the monopolist firm.     

Expanding mobile wireless capacity: The challenges presented by technology and economics

As demand for mobile broadband services continues to explode, mobile wireless networks must expand greatly their capacities. This paper describes and quantifies the economic and technical challenges associated with deepening wireless networks to meet this growing demand. Methods of capacity expansion divide into three general categories: the deployment of more radio spectrum; more intensive geographic reuse of spectrum; and increasing the throughput capacity of each MHz of spectrum within a given geographic area. The paper describes these several basic methods to deepen mobile wireless capacity. It goes on to measure the contribution of each of these methods to historical capacity growth within U.S. networks. The paper then describes the capabilities of 4G LTE wireless technology, and further innovations off of it, to further improve network capacity. These capacity expansion capabilities of LTE-Advanced along with traditional spectrum reuse are quantified and compared to forecasts of future demand to evaluate the ability of U.S. networks to match future demand. Without significantly increasing current spectrum allocations by 560 MHz over the 2014–2022 period, the presented model suggests that U.S. wireless capacity expansion will be inadequate to accommodate expected demand growth. This conclusion is in contrast to claims that the U.S. faces no spectrum shortage.
