Unbundling and infrastructure competition for broadband adoption: Implications for NGA regulation

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.     

Multilevel governance and broadband infrastructure development: Evidence from Canada

This paper investigates the contributions of digital infrastructure policies of provincial governments in Canada to the development of broadband networks. Using measurements of broadband network speeds between 2007 and 2011, the paper analyzes potential causes for observed differences in network performance growth across the provinces, including geography, Internet use intensity, platform competition, and provincial broadband policies. The analysis suggests provincial policies that employed public sector procurement power to open access to essential facilities and channeled public investments in Internet backbone infrastructure were associated with the emergence of relatively high quality broadband networks. However, a weak essential facilities regime and regulatory barriers to entry at the national level limit the scope for decentralized policy solutions.     

The impact of different fibre access network technologies on cost,competition and welfare

Using a novel approach to the evaluation of new network technologies that combines an engineering cost model with a differentiated multi-player oligopoly model with wholesale access regulation this article evaluates the choice among different Fibre-to-the-Home (FTTH) architectures. The cost modelling relies upon an engineering bottom-up approach that feeds into a competition model. For addressing competition the pyramid model was chosen, which is an extension of the Hotelling model to multiple firms/services. The paper solves for price setting Nash equilibria between an incumbent, wholesale-access-based entrants and cable as an additional fully integrated network competitor. Welfare tradeoffs are highlighted with respect to cost differences and QoS differences between the various FTTH architectures and between the modes of regulation. According to the analysis architectures that can be unbundled (and that allow for greater speeds) outperform, from a social welfare perspective, architectures that (realistically) allow only for bitstream access.     

Ultra-fast broadband access and productivity: Evidence from Italian firms

We study the impact of ultra-fast broadband (UFB) infrastructures on the total factor productivity (TFP) and labor productivity of firms. We use unique balanced panel data for the 2013–2019 period on incorporated firms in Italy. Using the geographical location of the firms, we merge firm-level data with municipality-level information on the diffusion of UFB, which started in 2015. We derive consistent firm-level TFP estimates by adopting a version of the Ackerberg et al.’s (2015) method, which also accounts for firm fixed effects. We then assess the impact of UFB on productivity and deal with the endogeneity of UFB by exploiting the physical distance between each municipality and the closest optical packet backbone node. Our results show an overall positive impact of UFB on productivity. Services companies benefit the most from advanced broadband technologies, as do firms located in the North-West and South of Italy. We further decompose the impact of full-fiber networks from mixed copper-fiber connections and find that the former significantly contribute to enhancing firm productivity. Finally, by exploiting Labor Force Survey data, we provide suggestive evidence that productivity increases from UFB might be related to structural changes at the workforce level.     

A retrospective study on the regional benefits and spillover effects of high-speed broadband networks: Evidence from German counties

This study aims to assess the economic benefits of high-speed broadband within and across neighboring counties in Germany. Utilizing a balanced panel dataset of 401 German counties with data from 2010 to 2015 as well as different panel estimation techniques, we find that an increase in average broadband speed has a significantly positive effect on regional GDP in the average German county. Furthermore, we find that broadband deployment in German counties induces not only substantial economic benefits in terms of direct effects within counties but also positive regional externalities across counties. According to our estimation results, an increase in average bandwidth speed by one unit (1 Mbit/s) induces a rise in regional GDP of 0.18%. This effect is almost doubled if we also take regional externalities into account (0.31%). Moreover, we find that regional agglomeraton effects are of particular relevance for rural counties. Our cost-benefit analysis of subsidies based on conservative estimates suggests efficiency gains, as the total economic per capita benefits (€164) of subsidy programs to encourage broadband expansion exceeded their associated per capita costs (€114).     

Investment flexibility and competition modeling for broadband business

In the new era of the telecommunications business field, a large number of potential investors are capable of entering into the market of the broadband services provision. This paper provides a model for analyzing the new perspectives for new investors in this field. It integrates compound Real Options and Game Theory techniques and adopts price competition analysis, for the broadband services provision, in order to find the optimal business strategy. Finally, it applies the analysis to a real life business case by formulating and solving it.     

Computing welfare losses from data under imperfect competition with heterogeneous goods

We study the percentage of welfare losses (PWL) yielded by imperfect competition under product differentiation. When demand is linear, even if prices, outputs, costs and the number of firms can be observed, PWL is arbitrary in both Cournot and Bertrand equilibria. If in addition the elasticity of demand (resp. cross elasticity of demand) is known, we can calculate PWL in a Cournot (resp. Bertrand) equilibrium. When demand is isoelastic and there are many firms, PWL can be computed from prices, outputs, costs and the number of firms. We find that price–marginal cost margins and demand elasticities may influence PWL in a counterintuitive way. We also provide conditions under which PWL increases or decreases with concentration.     

Network investment,access and competition

This paper analyzes the role of different contract types and access regulation on innovation and competition in telecommunications in the context of Next Generation Access Networks. Within a standard duopoly model, it is shown that ex-post access contracts lead less often to the duplication of investment, but to a wider roll-out compared to a market in which such contracts cannot be offered. In comparison to such ex-post contracts, ex-ante contracts lead to an even wider roll-out, but to a less frequent duplication of investments. Ex-ante contracts in particular, but also ex-post contracts, can be used to dampen competition.     

The broadband digital divide and the economic benefits of mobile broadband for rural areas

Broadband is becoming increasingly important to national economies and the personal lives of users. However, broadband availability and adoption are not diffusing in rural and urban areas at the same rates. This article updates the rural broadband digital divide, with special attention paid to mobility. Empirical estimations of broadband provision and usage in the US show that rural areas have fewer high-speed fixed and mobile providers but more slower-speed fixed providers than urban areas. While rural availability of mobile broadband is lower than in urban areas, it still helps fill in gaps in fixed broadband coverage in rural areas. The rural gap in fixed broadband usage remains, but the mobile broadband usage gap disappears after controlling for household demographics. The raw broadband usage gaps between rural and urban households are proportionally greater for low-income households. The potential for mobile broadband to benefit rural areas through economic development is also examined.     

How does broadband infrastructure promote entrepreneurship in China: Evidence from a quasi-natural experiment

Using the Broadband China strategy as a quasi-natural experiment, our study attempts to understand how broadband infrastructure (BI) impacts entrepreneurship in China. Employing a staggered difference-in-difference approach, we argue that BI significantly enhances entrepreneurship, and that this conclusion holds after considering the identification of assumptions and a range of other factors that may interfere with the estimation results. The mechanism exploration reveals that human capital agglomeration and financial development are the main pathways through which BI encourages entrepreneurial activities. Furthermore, the positive effects of BI are bigger in eastern cities, high market-oriented cities, and among cities with excellent traditional infrastructure. Our findings reveal the role of improving BI in facilitating the development of new ventures in China.     

Estimating the benefits from collaboration: The case of SEMATECH

SEMATECH (SEmiconductor MAnufacturing TECHnology) was established in 1987 as a not-for-profit research consortium with an original mission to provide a pilot manufacturing facility where member companies could improve their semiconductor manufacturing process technology. Since its inception, SEMATECH's mission has become more general. This paper presents the findings from a quantitative case-based analysis of the returns to member companies from their investments in SEMATECH. The findings suggest that SEMATECH has provided an organizational structure in which important processes and technologies have been advanced which could not have been justified on economic grounds outside of a collaborative research arrangement.     

An index for cross-country analysis of ICT infrastructure and access

The purpose of the present article is to devise an index for measuring and analyzing the divide among countries in the area of information and communication technology (ICT) infrastructure and access. Understanding the fact that there are many factors influencing the digital divide, this research is not intended to measure the digital divide in terms of different inequalities, but it rather attempts to take only one of the most important of these factors (maybe the most important of them) into consideration for measuring and analyzing divide between countries, that is, ICT infrastructure and access. In contrast to the majority of the indices in this context, the proposed index is built upon defining and conceptualizing ICT infrastructure and access. In addition, the index uses core ICT indicators on which the international community and experienced modelers have consensus that they measure the information society suitably. Therefore, the index can be exploited as the basis and standard for internationally comparable statistics in ICT infrastructure and access area. Moreover, it is the second index based on core ICT indicators after the Digital Opportunity Index (DOI) that was developed by the International Telecommunication Union (ITU) in 2005. However, in the current article, using Data Mining methods, Markov Chain Monte Carlo (MCMC) (to impute missing data) and Multi-Stage Factor Analysis (FA) (for aggregating the indicators), many problems and limits of the existing indices, the DOI in particular, such as the lack of data for analyzing ICT infrastructure and access, use of equal weighting or experts’ opinions to aggregate the indicators, are avoided. Since this index is developed by statistical procedures, it is flexible, adaptable, and modifiable over time while it sustains its original structure. It is comprised of two main dimensions: ‘ICT access’ and ‘coverage of mobile and access tariffs’ and 10 indicators. Finally, comparing the proposed index with the other indices in this field and gross national income (GNI) per capita of 150 countries, this index is tested; then, it is utilized to measure and analyze the divide between countries in the two dimensions, different geographical areas, economic conditions, and levels of ICT infrastructure and access.     

Competition,regulation, and broadband access to the internet

This paper reexamines the effect of the regulatory regime on both penetration and coverage of broadband access to the internet. The framework allows for an evaluation of policy initiatives, guidelines and measures to bridge the digital divide and to promote investment. A welfare analysis compares service-based with facilities-based competition and asks whether and how high-speed access to the internet should be subsidized. Using an approach similar to Valletti, Barros, and Hoernig (2002), the paper highlights the importance of population density for whether firms invest to provide internet access. The analysis reveals a trade-off between coverage and penetration.     

Economies and Diseconomies: Estimating Electricity Cost Functions

This paper presents estimates of the variable cost function ofelectricity generation. The cost function is estimated using a two dimensional definition of capacity utilization. Because electricity cannot be conveniently stored, generation facilities follow the load across demand cycles. Capacity utilization can be captured empirically in two ways. One is generation relative to capacity when a unit is connected to the system; the other is thepercent of time the unit is disconnected. The estimated cost function shows that both dimensions affect average cost, which generally declines as capacity utilization increases.     

Economic growth and broadband access: The European urban-rural digital divide

This paper estimates the regional effects of high-speed broadband coverage on economic growth in a panel of 1348 regions across all European Union Member States between 2011 and 2018. We distinguish between different connectivity speed levels by aggregating the available regional data across all existing broadband technologies, and investigate how regional differences in the contribution of broadband coverage to real economic growth can quantitatively explain the persistence of the European urban-rural digital divide. In order to make our results robust to endogeneity and disaggregated data availability issues, we employ a bootstrap-based bias correction for the dynamic fixed effects estimator. We find that expansions in the provision of lower-speed broadband access accelerated annual per capita growth in both urban and rural regions through diminishing returns to scale, but that the effects were weaker in those regions characterized by larger ruralization. High-speed broadband coverage, on the contrary, could only be significantly related to rural economic growth and had no impact within their urban counterparts. We find evidence that the costs of these high-speed rural connectivity expansions had not yet been offset, but that they exhibit increasing returns to scale with cut-off levels nearing full coverage. These results indicate that the high-speed digital expansion of rural Europe is a potential gamechanger for further rural development policies through its role as a general-purpose infrastructure, and consequently argue in favour of increased efforts to close the urban-rural digital gap.     

Bagging bundle benefits in broadband and media mergers: Lessons from Sky/Vodafone for antitrust analysis

The historic precedents in telecommunications antitrust findings have tended towards finding harm to competition when network operators integrate downstream and bundle the provision of applications and services. The reason for this is that market power in network provision is thought to be extended into the applications market(s). More recently however, proposed mergers have been between telecommunications and media distribution firms, both of whom have some degree of market power, already sell their own services in bundles, and who may or may not have been offering combined bundles already via contractual agreements. Examples include Sky/Vodafone in New Zealand, and Time Warner/AT&T in the United States as well as Vodafone/Unitymedia in Germany and Media Capital/Altice in Portugal. These complex proposed arrangements pose challenges to competition authorities, whose legal and procedural rules and precedents, especially those defining the relevant markets affected by the merger or vertical integration activity, have been developed from the analysis of simpler cases. These precedents may not be sufficient to analyse current cases, characterized by multiple products catering to heterogeneous consumer preferences, and consumers are not constrained to buying only one variant of the products in each of the upstream and downstream markets.We illustrate the challenges by way of a case study of the proposed merger between Sky and Vodafone, declined by the New Zealand Commerce Commission in February 2017. Limitations in existing market definition processes and the evaluation of market power where bundling already occurs risk overlooking complex demand-side interactions that influence the profitability and efficiency of various structural and contractual strategic choices. We propose that classic merger and antitrust analysis based on econometric cost-benefit analysis can be augmented by using simulation and numerical analysis of a range of bundle offers expected to be relevant in decision-making. We develop a simple model and use it to illustrate how it may be used to inform broadband and content mergers, and other complex antitrust cases, such the assessment of the effects of two-sided markets and firm pricing decisions.     

Standards, trade and competition in the emerging global information infrastructure environment

Decentralized construction of the Global Information Infrastructure (GII) is substituting market-driven, ‘de facto’ standards and voluntary agreements on standards for technical compatibility, in place of the engineering decisions once made by public (and quasi-public) telecommunications network operators. Due to strategic economic behaviours on the part of private businesses and national governments, the goal of a fully interoperable GII remains elusive. The Internet does not offer an entirely credible alternative model, as the standards that have facilitated its explosive growth also are contributing to serious congestion problems, and the solutions proposed point to the Internet's re-integration into the public switched telecommunications network. Technical standards will shape the GII's implications for international trade and competition, and thus raise important, but inadequately recognized issues for regulation, competition and trade policy.     

Access regulation, competition, and broadband penetration: An international study

The evolution of broadband penetration has shown substantial differences between OECD countries. This paper empirically investigates to what extent different forms of regulated competition explain these international differences. It distinguishes three modes of competition between broadband internet access providers that result from regulatory policies: (1) inter-platform competition; (2) facilities-based intra-platform competition; and (3) service-based intra-platform competition. In most countries these forms of competition co-exist although their intensity varies from country to country. Intra-platform competition may differ among countries depending on the degree of mandatory access obligations imposed by the regulator on the dominant network firm. Based on a sample of OECD countries, the analysis finds that inter-platform competition has been a main driver of broadband penetration. The two types of intra-platform competition have a considerably smaller effect on the broadband penetration. Linking these findings back to access regulation suggests that the “stepping stone” or “ladder of investment” theories might not provide the justification to impose extensive mandatory access obligations on DSL incumbents.     

Estimating willingness-to-pay for broadband attributes among low-income consumers: Results from two FCC lifeline pilot projects

Recent studies have confirmed that broadband adoption (as opposed to simply having access to broadband infrastructure) is positively linked with economic growth. In light of this, federal policy efforts have switched from focusing mainly on the provision of infrastructure to more explicit adoption-oriented efforts. One of those efforts was the Federal Communications Commission’s (FCC’s) Low-income Broadband Lifeline Pilot Projects, which ran from 2013 to 2014. The program worked with 14 private telecommunications firms to subsidize household broadband adoption for low-income households by providing discounted monthly and equipment costs. Low-income households are an important component of the broadband adoption puzzle: between 2003 and 2013, the adoption gap between low-income and high-income households actually increased by 5% points. This paper focuses on two specific FCC Broadband Lifeline Pilot projects that allowed consumers to make choices among different options, such as data allowance, speed, and wireless vs. wired connections. Conditional logit models are used to develop estimates of consumer’s willingness-to-pay for specific broadband attributes. The results indicate that low-income consumers have a preference for smartphone connections (versus aircards) – and that this effect is even more pronounced for those households earning less than $20,000; that low-income consumers have a preference for wired connections (versus wireless); and that there is evidence that low-income consumers are willing to pay for an extra GB of data each month – but not for the speed of their connection.
