The common idea of open access policy is that it refers to the sharing of particular elements, such as wholesale access networks, backhaul, under-sea cable and internet exchange points in fixed and mobile networks. In broadband networks, the use of open access policy usually refers to the infrastructure parts, which are considered a bottleneck. Many regulators have generally focused open access policy on fixed broadband networks, especially digital subscriber line (DSL) technology, in the last decade. Local loop unbundling (LLU) regulation is one of the main strategies for the regulator to open access to an incumbent’s bottleneck network in order to soften its monopoly power and encourage competition in the DSL broadband market. The OECD countries have different strategies regarding unbundling local loop and infrastructure competition, as the characteristics and infrastructure networks of countries vary. There are currently more choices of next generation network (NGN) technologies to develop. While local loop unbundling may not be applied fully to NGN development (the cost is not sunk, more technologies are available to implement, incentive of investment by operator), it can indicate benefits and drawbacks of open access policy in the past decade that can be adapted to NGN.The empirical results of this study show that during 2002–2008, LLU regulation was one of the strategies used to increase broadband adoption in countries that had difficulty encouraging infrastructure competition. Unbundling regulation can therefore be implemented carefully and differently in each country that has inefficiency that is harmful to consumers in its market from a monopoly incumbent. Infrastructure competition, on the other hand, is introduced as another strategy to increase broadband adoption. The empirical results of this study indicate that infrastructure competition can be used as a strategy when there are already enough infrastructures in the area or country. These results support the idea of using open access and infrastructure competition policy depending on the existing competition of broadband infrastructure in each country. 相似文献

This study examines OECD fully unbundled and line sharing monthly wholesale prices for 2002–2008. The results are informative with economic analysis appearing to inform regulator decision making. However, with the cost proxy (viz., copper-wage relative price, population density, urbanisation and business line penetration), regulator costing methods (long run incremental and fully allocated cost), and time trend arguments only explaining approximately 40% of the price variation there remains ample unexplained variation, and political and institutional variables may help reduce this. Finally, both price series are subject to increasingly rapid value declines, although the patterns are somewhat distinct. This suggests that initial prices are truly transitory. 相似文献

There has been an extensive debate about the role of broadband access regulation on market outcomes. This paper estimates the impact that the different modes of competition have had on broadband take-up to date, using a data set for EU27 countries. We find that ULL, which is one of main types of access-based competition in Europe, has had a positive impact on broadband take-up. However, the impact of ULL becomes smaller as its share increases. That is, ULL entry is less effective in areas where ULL take up is already high. Further, there is evidence of a crowding out effect between ULL and inter-platform competition. This means that ULL is less effective in enhancing broadband penetration in the areas where alternative networks already have a significant share of broadband lines. 相似文献

This study analyzes the anticipated economic effects arising from the introduction of the mobile virtual network operator (MVNO) system in the mobile communications service market. For the analysis, actual data (or estimated data)—such as price elasticity, the number of subscribers, traffic volume, rate, and access charge—were combined with an assumption about a competition scenario in the future market. Based on this analysis, consumer surplus, and change in the service provider's profits were estimated according to the type of policy that may be adopted for the MVNO system by the regulator. The results of the analysis indicate that consumer surplus appears to increase largely because of the reduction of the mobile service rate by the promotion of “service-based competition,” which occurs upon adoption of an MVNO policy in the mobile communication service market. Moreover, the introduction of an MVNO system into the mobile communication market seems to be socially beneficial regardless of policy type if access charges are set reasonably by a cost-plus or retail-minus method. In particular, in order to make sense of the introduction of a special MVNO, whether by the cost-plus method or the retail-minus method, the correct discount rate must be used in setting an access charge between the special MVNO and the significant market power (SMP) mobile network operator (MNO). 相似文献

Within a few days of each other in early 2009, the national governments of Australia and New Zealand announced separate plans to invest heavily in advanced broadband networks. Taxpayers in each country will contribute at least half the estimated cost of fibre-to-the-premises networks reaching the overwhelming majority of households and businesses within 8–10 years. These complex and controversial forms of ‘public private interplay’ demonstrate three trends: a shift away from the liberalization and privatization policy consensus of the last two decades; shared convictions about the anticipated size of fast broadband’s economic and social benefits, and about the need for wholesale-only fixed line network operation to maximize those benefits; and the unlikely impact of the global financial and economic crisis in stimulating investment in particular infrastructures seen as critical to the national economies that emerge from it. This article discusses industry structures and regulation in Australia and New Zealand, their long history of public investment in telecommunications and the recent popularity of public private partnerships (PPPs) with Australian state governments. It outlines the ambitious broadband plans and surveys their prospects. Like so many other policy actions following the global economic crisis, these are distinctively national responses to internationally shared challenges. 相似文献

A number of countries around the world are trying to promote competition at the local loop as demand for higher bandwidth to the home increases. Different technologies (xDSL, cable modems, and wireless local loop) offer alternative solutions and the issue for regulators is to design a framework that promotes competition and investment. Regulators can promote competition in a number of ways, but two “pure” strategies are services and infrastructure competition. This paper models the regulator and incumbent–entrant interactions explicitly in order to understand how the structure of the voice services might evolve under different regulatory frameworks. Our analysis suggests that a “mix” of infrastructure and service competition like the one promoted in Netherlands, stimulates investment by incumbents and entrants alike and offers better consumer benefits. The message for policy makers is that the introduction of “sunset clauses” provides new entrants with strong incentives to invest while allowing them to enter in service competition and to acquire important knowledge about their new market. 相似文献

Investments in next generation access networks (NGANs) ask for a new set of regulatory remedies. This paper contributes to this debate by focusing on three issues: the migration from the legacy copper network to the NGA infrastructure, and how wholesale pricing regulation might affect this process; the introduction of differentiated wholesale remedies according to geographical differences in NGAN deployment; the impact of co-investment decisions on market outcomes and their interplay with access regulation. Using the recent economic literature, arguments and possible guidelines are proposed, which might be useful to regulators and policy makers. 相似文献

Over the past 40 years, telecommunications policy worldwide has been dominated by the privatisation of former government-owned firms, the pursuit of increasing competition as well as the delegation of day-to-day operations of industry decision-making and oversight from core governments to autonomous regulators sitting at arms-length from political decision-making. One of the most (apparently) dramatic reversals of this trend has occurred in Australia where the federal government has set up a state-owned company (NBN Co) to fully replace and upgrade the fixed-line infrastructure for voice and broadband communications for the entire country. Some argued that the NBN heralded a reversal of a “failed, neoliberal” deregulation and pro-competition policy agenda in Australia, and a return to “social democratic” values. The NBN has attracted interest as a possible model for other governments looking to fund broadband infrastructure.The NBN Co's network is nearing completion. It has proved disappointing in many ways, with costs escalations, missed deadlines and a downscaling of the original full-fibre footprint to a mixed technology model (MTM). It has also proved politically divisive, with some claiming the MTM changes represent the reassertion of a neoliberal political agenda. In this paper, we trace the evolution of the fixed-line telecommunications industry in Australia from the 1980s to the present along the dimensions of privatisation, deregulation and competition in voice, broadband and policy settings. We find that contrary to popular political rhetoric, the Australian industry reforms have been characterised by only a partial and inconsistent progression towards the international policy objectives. In particular, ongoing government ownership of the incumbent created perverse incentives for both regulatory and industry actors and ensured political involvement in import network investment and operations decisions which in other jurisdictions are delegated to private-sector owners and regulators at arms-length from political influence. We contend that the NBN was not a social democratic response to failed neoliberal policies, nor was the MTM a neoliberal reassertion. Rather, the politicisation of the NBN is a function of the inability to decentralise ownership and control of the industry away from the government. These issues will continue to dominate the Australian debate, as the statutory context requires the privatisation of the NBN within five years of its projected 2021 completion. Extreme caution is warranted for jurisdictions looking to the NBN model for guidance. 相似文献

In recent years, the preference for purely private funding and ownership of telecommunications networks has given way to a ‘new wisdom’ that some form of public funding is now likely necessary if faster and more capacious next generation access (NGA) networks are to be constructed in a timely fashion for the majority of the population. Policy-makers are charged with deciding how that public investment will take place. One approach is via Public-Private Partnerships (PPPs), where public and private actors collaborate in UFB (Ultrafast Fibre Broadband) investment, construction and operation. However, the body of analysis of PPPs in NGA networks to guide policy-makers is scant.By using the concept of regulatory commitment, the paper compares the experiences gained in a hold-up situation in PPPs in other infrastructures (e.g. roading) with the UFB context. A case study of New Zealand's Ultrafast Fibre Broadband Initiative is used to draw new insights for government purchasers and regulatory agencies. In comparing the different forms of PPPs, the paper shows that UFB PPPs reverse the typical direction of financing and ownership observed in roading PPPs. Financing and asset ownership are separated in UFB PPPs, increasing the potential for misalignment of incentives and the likelihood that the public party can use its legislative powers to alter regulatory settings after the PPP contract is signed, and thereby hold up the private party once existing network assets are sunk. Whilst the government instigating the PPP may not be inclined to act opportunistically, a successive government facing different political priorities does not face the same incentives. To the extent that the private party can anticipate this risk, it should structure the initial agreement to ensure that the public party is penalised if such an event occurs (i.e. an automatic right to favourable renegotiation or payment of compensation). Such terms will discourage opportunism, so that the project benefits from time-consistent alignment of incentives and objectives. 相似文献

The concept of open access (OA) plays a central role in the ongoing academic and political debate on the appropriate regulatory framework for next-generation access networks in Europe. However, clear policy conclusions on the effect of OA regulation were usually precluded by a fundamental lack in common understanding what actually defines an OA policy and along which dimensions of OA regulation can be structured. This paper attempts to reconcile these diverse views by offering a definition and a conceptual framework by which OA endeavors can be identified and uniquely classified. The framework encompasses, among others, mandated OA regulation of vertically integrated firms, public-sector participation, co-investments, and OA in the context of vertical separation. Along this framework, the extant economic literature is surveyed with regard to aspects of competition and social welfare, investment and innovation, as well as practical and legal issues. Based on these insights, a policy guideline is developed that shall assist policy makers in identifying the appropriate OA scenario for the regulation of telecommunications infrastructure. 相似文献

The telecommunications sector is innovative and its innovations strongly affect the growth of the rest of the economy. While regulatory policy has therefore shifted towards innovation as its major goal besides enabling competition, there appear to be tensions between regulation, competition and innovation. This paper identifies as the roots of these tensions the consumer protection objective enshrined in regulatory legislation and the regulatory neutrality issues arising from stranded assets, loss of labor rents, loss of services by captive customers, and the threat to regulators from looming deregulation, all of which are associated with innovations. This paper identifies some similar threats to innovation in unregulated sunk-cost industries with a monopolistic incumbent. A very simple model shows that a comparison of innovation incentives in such an unregulated industry with a regulated one leads to ambiguous results. However, the prospect of converting a regulated industry into an unregulated one after the innovation has occurred will unambiguously increase innovation incentives. 相似文献

Despite nearly 30 years of research focused on improving new product development (NPD) processes, recent research reveals that these improvements have failed to materialize as expected. Additionally, in today's continuous-change business environment, managers are focused on reducing cycle time in nearly all operations, including NPD, in order to realize acceptable returns on investments more quickly. Thus, we must not only be better but also faster at NPD, specifically at compressing the cycle time between new product successes, i.e., accelerating success-to-success velocity and not just accelerating each NPD project. But, how can businesses both improve the probability of new product successes and also speed up the process of doing so? This paper proposes that formalizing front-end processes will certainly help. Specifically, a process is presented which draws on customer value research that ought to help clarify the traditional “fuzzy front end” of NPD processes, resulting in consistently more successful new products. 相似文献

Buying firms are increasingly looking to suppliers for technological innovations that enhance the competitive position of their new products. However, extant research provides limited guidance on how buying firms may gain access to suppliers' innovative technologies. To address this gap in the literature, we draw from social exchange theory to posit sequential relationships among buyer behaviors, preferred customer status, and supplier's willingness to share technological innovations. We test our assertions by applying structural equation modeling statistical analyses to survey response data from 233 sales personnel of production good suppliers in the U.S. automotive industry. Whereas our results show that two buyer behaviors – early supplier involvement and relational reliability – positively affect preferred customer status, a third behavior – share of sales – has no effect. In turn, we find that preferred customer status is positively associated with supplier's willingness to share new technology with the buyer. Further, our findings indicate that preferred customer status fully mediates the benefits exchanged within a buyer–supplier relationship. Hence, our study highlights why buyers seeking innovations should take care that their behavior is appropriate for managing suppliers' perceptions. Accordingly, our results provide specific guidance to buyers as to how they may increase their access to suppliers' new technologies. 相似文献

This paper develops an investment/pricing model for the deployment of basic broadband networks which, along with other applications, is applicable to public–private partnership projects. In particular, a new investment model is suggested to be used for finance deployment over a longer term by enabling both private and public investors to participate in the roll-out of next generation access (NGA) infrastructure. This so-called “long-term risk sharing concept” has several notable benefits compared with the traditional regulatory approach. Above all, the model enables both private operators and public authorities to share the risk of investing in NGA infrastructure. Thus the model offers a way for public authorities to achieve a timely and countrywide roll-out of NGA networks, including in areas where NGA investment would otherwise not occur. 相似文献

The government of New Zealand is currently building a nation-wide fibre-optics network, a project known as the Ultra-Fast Broadband (UFB) initiative. The UFB network will cover 75 percent of New Zealanders over 10 years and will cost NZD $1.5 billion to the New Zealand government. The technical and economic characteristics of the new network will have a deep impact on the current landscape of the telecommunications markets. Institutional arrangements are in place for the development of the New Zealand's UFB: a government-owned agency, Crown Fibre Holdings (CFH); private investors who jointly with CFH own the Local Fibre Companies (LFCs) which will operate the UFB; and Retail Service Providers (RSP) that will provide end-user services by purchasing wholesale services to the LFCs. Relying on a normative economics approach that uses recent advances in the theory of platform-based markets with cross-network effects – also known as theory of two-sided platforms – the paper proposes a novel view of the way markets over the UFB will unfold. On one hand, the theory is used to explain the rationale behind regulatory decisions already made and their effect on the development of UFB-based markets for contents and services. Such analysis is followed, on the other hand, by the introduction of a simple taxonomy for the RSPs which provides the framework to argue about the most likely scenarios for service deployment and competition to develop over the UFB. The analytical framework reveals that the UFB ecosystem will be fraught with cross-network externalities which are the basis for regulatory decisions already adopted and the source of particular forms of strategic behavior adopted by the UFB-based market innovators. 相似文献
