互联网电视真相

什么是互联网电视？“顾名思义就是可以上网的电视,但并非接上网线就可所向披靡地浏览网页,你只能看到电视厂家推送的有限内容。”电视机生产企业会这样跟你解释,这听起来有点古怪,但事实就是如此。     

The business case of a network that serves both public safety and commercial subscribers

Deploying a single nationwide broadband wireless network to serve all public safety users would have great advantages over the existing fragmented public safety systems. A nationwide system could be created to serve both public safety and commercial subscribers, which would allow a provider to exploit important economies but force it to meet the more costly requirements of public safety. This paper analyzes the viability of a public-private partnership that serves public safety and commercial subscribers from a for-profit provider's perspective. A model is presented that estimates the net present value (NPV) of a wireless network by calculating costs based on the number of cell sites required and revenue based on the projected number of subscribers acquired. The model is applied to both a network that serves only commercial subscribers on 10 MHz of 700 MHz spectrum and a public-private partnership that serves commercial subscribers and public safety personnel on 20 MHz of 700 MHz spectrum. It is found that NPV is greater for the public-private partnership than for the commercial-only network for any population density, which shows that the value of 10 MHz of spectrum exceeds the cost of meeting public safety requirements. Furthermore, the paper demonstrates that NPV/cell increases with population density, so urban areas are profitable and rural areas are unprofitable. The paper demonstrates that a partnership covering 94% of the US population breaks even because the most urban 56% of population subsidizes coverage for the next 38%. If initial deployment is subsidized, a financially sustainable public-private partnership can serve much more than 94%. Additionally, it is shown that allowing urban municipalities to opt-out of the partnership can significantly increase the subsidies required.     

Assessing the effectiveness of a technical assistance program: The case of maize seed relief to vulnerable households in Zimbabwe

The recent economic downturn in Zimbabwe impoverished the majority of households. To assist vulnerable rural households improve their food security, the British Department for International Development implemented a seed relief program from 2003/2004 to 2005/2006 that emphasized recycling of maize open pollinated varieties (OPV). Using data collected from 597 households in six districts in 2006, this study assesses the effectiveness of the program in terms of its targeting of beneficiaries, the flow of information from participating NGOs to beneficiaries on the need to recycle the seeds, and the level of recycling done at the end of the program. The empirical results suggest that the targeting method participating NGOs use inadvertently excludes relatively vulnerable households while including large proportions of relatively well-endowed households in the program. The choice of varieties to distribute is guided more by the ecological adaptability of available commercial seeds and less by preferences of beneficiaries. Notwithstanding the fact that seed selection information is critical in encouraging beneficiaries to recycle distributed seed, not all of them received it. In conclusion, it may be stated that the program undoubtedly contributed to increased food productivity by vulnerable households but its overall effectiveness could have been enhanced through (i) the involvement of the beneficiaries in the choice of types of seed to be distributed, (ii) better targeting of beneficiaries, and (iii) improved information flow between NGOs and beneficiaries.     

The diffusion of television advertising

This study is an empirical examination of the diffusion of the use of network television advertising by manufacturing firms. The results indicate that manufacturers of consumer goods were likely to make use of television advertising sooner than manufacturers of producer goods and that, among producers of consumer goods, those producing more easily differentiable products were likely to adopt sooner than those producing more standardized products. Manufacturers of products sold in larger geographic markets were found to adopt sooner than those producing products sold in smaller markets. Larger market share was also found to induce earlier adoption of television advertising.     

The emerging oligopoly of pay-TV in the USA

The pay-television industry in the USA has been developing very rapidly in the past five years and is providing network quality alternatives to the mass taste programming of commercial television. However, the industry has been developing along lines very similar to the early history of radio in the USA with the emergence of strong distributor networks, restrictive affiliation contracts, and wide-spread vertical integration across all stages of production. History and economic efficiencies suggest that the result will be a strong oligopoly market structure. The proper public policy, then, is to insure that the unavoidable degree of concentration is not greater than that needed for efficiency reasons.

Where is the opportunity in opportunity zones?

In December 2017, the U.S. Congress passed into law the Opportunity Zone (OZ) program. As an OZ, designated low-income census tracts provide considerable tax breaks to property investors, intending to attract investments and spur economic growth. As the success of the program is dependent on investors' responses, we analyze market reactions in a difference-in-differences framework. We identify two potential effects on property markets: tax breaks for investors and expected land value appreciation. Our results show that tax breaks are priced efficiently. Qualified properties increase by 7–20% in price, while vacant land increase up to 37%. In contrast, we find limited signs of expected land value appreciation.     

Controlling unwanted communications to the home

A greater volume of communications into the home increases concerns about offensive messages and unwanted solicitations. The author presents legal, regulatory and technical approaches to giving individuals more control over the communications they receive through the mails, over the telephone network, via broadcast television, and from cable TV. Technical means for allowing greater subscriber control are available, but they generally receive low priority in system design. Although receivers' rights to avoid unwanted communications may conflict with senders' rights to free speech, the author favours placing more choice and responsibility on the recipient.     

How Much Will Consumers Pay? A Hedonic Analysis of the Cable Television Industry

Because cable television is the classic example of a bundled commodity, it is difficult to determine how consumers value individual cable networks offered on a typical system. This paper uses a modified hedonic framework to determine the marginal willingness to pay by consumers for individual cable networks. The traditional hedonic framework is adapted to allow for the lack of competition on the supply side of the market. It is clear that consumers do value some types of programming more than other types. Sports, news, and family programming all have positive implicit prices while program guides have negative marginal prices.     

Cable as choice

The major benefit that cable TV has to offer the UK customer is choice. The question is: should choice be limited in any way? Vested interests in the television and film industry are pressing for restrictions on two ‘no go’ areas-live sport and first release films. Gareth Locksley argues that there is no case for restrictions, and that choice will benefit the television and film industries and the consumer.

COVID-19 and changes in content usage behavior: The case of South Korea

This study examines changes in content usage time due to the COVID-19 pandemic in South Korea using Korean Media Panel data for the period 2011–2020 and explores the reasons for these changes. This study focuses on four principal contents: television programs, movies/videos/user-created content, traditional telecommunication services, and chatting/messenger/social network services. The empirical results indicate an increase in usage time for the four principal contents, as well as total content usage time because of the pandemic. The results also show that average Korean people stayed longer at home after the onset of the pandemic, leading to an increase in the time spent on all the principal contents, except for traditional telecommunication services, as well as an increase in total content usage time. Furthermore, this study suggests that whereas the effect of the pandemic on television program viewing time was mainly attributable to changes in time spent at home because of the pandemic, the effect on other contents was mainly caused by non-location-related factors. This study predicts changes in content usage time after the end of the pandemic and provides strategic suggestions.     

The Impacts of Remittances, Residency Status and Financial Attachment on Housing Tenure for Mexican-Heritage Americans: Inferences from a New Survey

Immigration has and will continue to alter the composition of housing demand in the United Sates. In this article, we analyze results from a new survey of Mexican-heritage households to draw some inferences about tenure choice within that group. Some measures of attachment to the United States—residency status and the amount of money sent to relatives and friends in Mexico—suggest that, among Mexican immigrants, permanence is a key determinant of homeownership in the United States. More specifically, being a citizen increased the probability of ownership, whereas being undocumented reduces the probability. Surprisingly, after controlling for residency status, length of tenure in the United States does not predict tenure status, except that those who refused to report length of tenure were more likely to have higher tenure status. Those who sent remittances home to Mexico were less likely to become homeowners.     

Industry self-regulation of food advertisement to children: Compliance versus effectiveness of the EU Pledge

This research examines the effectiveness of the EU Pledge, a self-regulation initiative of leading food companies at the European level, in restricting television advertising of food and drink products high in fat, sugar or salt (HFSS) to children. In October 2011 and 2014, television program of ten German television networks was recorded on a weekday and a weekend day. Data was analyzed using content and regression analysis. Advertised products were examined for their compliance with the nutrient criteria of the EU Pledge and the UK OFCOM nutrient profile model. The sample contains 88 h of advertising with a total of 697 child-targeted food and beverage advertising (CFBA). The results indicate that the number of CFBA broadcasted in television program declined from 2011 to 2014 for both Pledge signatory and non-signatory companies with an overall stronger reduction in children’s compared to non-children’s program. Our findings demonstrate that CFBA broadcasted in children’s program by Pledge members comply by and large with the EU Pledge nutritional criteria in 2014. However, in the same year the probability of CFBA aired by signatory companies in non-children’s program to meet the nutrient profile criteria of the EU Pledge was low. Furthermore, the majority of CFBA of signatory companies do not meet the OFCOM nutritional criteria even in the children’s program. Thus, the effectiveness of the EU Pledge in reducing children’s exposure to child-targeted advertising of HFSS foods and drinks is limited by the focus on children’s program and the relative lenient nutritional criteria agreed on by signatory companies. Based on our results we derive recommendations for industry and policy.     

The competition among mobile network operators in the telecommunication supply chain

In the mobile telecommunication sector, the high competitiveness has increased the complexity of strategic interactions among operators. As the vertical integration has become anything but a choice and not a compelling technical solution, the contest takes place at different levels of the components of the operator value chain: the network infrastructure, the service development and supply, and the relationship with consumers.Mobile virtual network operators act as retailers and concentrate on the last segment of the value chain by establishing commercial agreements with hosting network operators, which act as manufacturers, to get access to radio communications infrastructure. Productive processes of mobile services offered by operators are different and this difference is imperceptible to customers. Processes difference mainly consists in the infrastructural diversity of the operators and implies different consequences on each network service element.A model has been defined to analyze the consequences of such diversity in the competition among HNOs, MNOs, and MVNOs by focusing the attention on the characteristics of the call path, in dependence of the types of operators. In fact, many variables interact to define the call path, such as marginal costs and revenues, infrastructural investments, and interconnection charges among operators. The analysis of the results, obtained by the model, gives information on variations of retail prices, market shares, and profit allotment, to adopt the proper strategies. In particular, the model results shed light on how certain MVNOs should enter the markets and adopt a collaborative strategy with HNOs. The model owns the capability of being applied to different contexts, thus representing for the regulator a potential instrument of relevant usefulness.

Changing dynamics of the overseas marketplace for TV programming: The rise of international co-production

This article examines the recent strategy adopted by the US television production industry in coping with the changing worldwide media environment. Developments in the USA include the commercial networks' declining audience share, the increasing penetration of cable TV, and spiralling production costs; abroad, the coming of age and increased sophistication of the televesion industry and the strengthening of programme import regulations are significant. Access to foreign markets is becoming critical to the financial equation of US producers and distributors of high-budget TV programmes. International co-production is the response to the new dynamics of world-wide television programming and a product of economic necessities.     

Can open internet access be imposed upon European CATV networks?

Broadband over cable television networks has become a growing force on the retail market in the EU. Thus, a debate has always been raised whether cable television networks should also be subject to open internet access obligations as PSTN and fibre. This article aims to share its view from a legal perspective. In order to do so, it conducts a survey of the current regulatory measures on broadband over cable television networks within the 27 EU Member States, and then carries out an in-depth legal analysis on Member States that attempted to regulate broadband over cable television networks. The conclusion is that broadband over cable television networks is currently deregulated, and will probably remain so in the future.     

Diversification of cable television firms into broadband products

This research provides a new perspective to investigate the broadband diffusion in eight states of the U.S. by studying the two-stage entry decisions, namely, upgrading and subsequent product decisions, by the cable television system operators, one of the early dominant players in the broadband market, and examines the role of competition, market characteristics and firm heterogeneity in the cable company's decisions in a dynamic setting. Comparing the empirical results of the decision models of both stages can give new insights into the dynamics of broadband diffusion. The empirical results show that the subsequent product decision is affected more by the demand determinants, while the upgrading decision is affected more by the cost determinants. The results also indicate that policies which aim to reduce the entry cost such as a low city fee can largely encourage firms to upgrade the network, while subsequent policies that help boost the demand can help firms diversify into new digital services early. The effectiveness of competition policy in the broadband diffusion is confirmed in both stages. Strategic responses by cable firms to the presence of RBOCs are more noticeable in the second-staged product decision than in the first-staged upgrading decision.
