The limitations of market-based regulation of the electronic communications sector

The European Union has recently implemented a system of regulation for the sector based on principles of competition law. The regulatory framework includes 18 markets where Regulatory Authorities should consider imposing ex ante obligations on dominant players. The paper explores the economic methodology being employed in particular to define market boundaries and concludes that the sector is too unstable for this approach to provide predictability and encourage long-term investment. In particular, emerging infrastructures and services can easily be captured while legacy networks remain subject to perpetual regulation. There are significant costs of excessive regulation and alternative approaches may be better.     

Is telecommunications regulation efficient? An international perspective

This article addresses the efficiency of regulation policy in the telecommunications sector. First, the concepts of static and dynamic efficiency are reviewed, with the main policies used into achieve these goals identified, while distinguishing effective competition from industrial policy. Indicators are proposed that enable assessment of components of sector efficiency. These indicators are used to empirically investigate the link between regulation policy and economic performance for OECD Member Countries. The investigation is based on national differences in regulation policy and efficiency indicators. The results support the notion that asymmetrical ex ante regulation alone is not necessarily efficient, and that an ex ante policy, integrating an industrial policy, could favor dynamic efficiency.     

The role of competition and regulation in stimulating innovation – Telecommunications

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.     

Total factor productivity enablers in the ICT industry: A cross-country firm-level analysis

Advancements in productivity in the digital economy constitute an important engine for economic growth. What drives productivity dynamics in the information and communication technology (ICT) sector? This study examines the productivity dynamics of ICT firms across countries from the perspective of corporate balance sheets. We study the effects of intangible assets and leverage on productivity growth using firm-level panel data from five industrialized countries. We find that intangible assets positively affect the total factor productivity in the ICT sector. The positive effect of intangible assets on total factor productivity growth is larger for ICT manufacturing firms than for ICT service firms. We also find that leverage has a positive relationship with total factor productivity development in the ICT sector. In addition, our empirical results substantiated that productivity is catching up to the technological frontier. Furthermore, larger firms and/or younger firms generally show higher total factor productivity growth than their peers. Economies of scale are more prominent in the ICT service sector than in the ICT manufacturing sector. Our findings contribute to the understanding of cross-country productivity dynamics in the ICT sector at the firm level in the digital economy.     

A CDS approach to induce facilities-based competition over NGA networks

The current regulatory framework in the European NGA market provides the basic principles for the gradual migration from service-based competition over the legacy copper access networks to facilities-based competition over fiber-based Next Generation Access (NGA) networks. This paper initially reviews the related literature and shows that: (i) an unbundling policy that boosts entry by alternative operators promotes service-based competition but provides operators with disincentives to invest in network upgrade; (ii) there is no consensus about the optimal regulatory policy that promotes competition and encourages investments in NGA networks; and (iii) the reviewed research articles are not consistent with the current regulatory framework in the European NGA market in terms of both the evolution of the regulatory goals over time and the recommended regulatory settings. This paper aims to propose a novel approach in order to effectively meet the current regulatory goals using the recommended settings. It is shown that the proposed approach, which is based on the basic principles governing a Credit Default Swap (CDS), provides an effective migration path towards facilities-based competition over NGA networks.     

Strategic investments under competition for access provision

We examine competition for access provision when symmetric vertically integrated firms invest in infrastructure upgrades. Spillovers through access have two effects (a wholesale-profit effect and a retail-production effect) on infrastructure investment made by vertically integrated firms. When the vertically integrated firms freely set access charges, due to the dominance of the wholesale-profit effect, quality differentials endogenously occur between these firms (asymmetric equilibria). When access charges are regulated, symmetric equilibria occur with multiple equilibrium investments due to the retail-production effect. Because competition for access provision induces a strong incentive for infrastructure investment, it also achieves a higher social welfare than does access regulation.     

Foreign direct investment,information technology and economic growth dynamics in Sub-Saharan Africa

The research assesses how information and communication technology (ICT) modulates the effect of foreign direct investment (FDI) on economic growth dynamics in 25 countries in Sub-Saharan Africa for the period 1980–2014. The employed economic growth dynamics are Gross Domestic Product (GDP) growth, real GDP and GDP per capita while ICT is measured by mobile phone penetration and internet penetration. The empirical evidence is based on the Generalised Method of Moments. The study finds that both internet penetration and mobile phone penetration overwhelmingly modulate FDI to induce overall positive net effects on all three economic growth dynamics. Moreover, the positive net effects are consistently more apparent in internet-centric regressions compared to “mobile phone”-oriented specifications. In the light of negative interactive effects, net effects are decomposed to provide thresholds at which ICT policy variables should be complemented with other policy initiatives in order to engender favourable outcomes on economic growth dynamics. Practical and theoretical implications are discussed.     

Productive efficiency and firm exit in the food sector

This work examines the effects of productive efficiency on the survival of firms in the Greek food sector. Technical and scale efficiency scores are computed within a data envelopment analysis (DEA) framework and are used as explanatory variables in a parametric (Weibull) survival model. High technical efficiency increases the median survival time and lowers the hazard rate of exit. As the scale efficiency of a firm operating either at increasing or decreasing returns to scale approaches one (1), its theoretically maximum value, the expected median survival time, is maximized for all types of exits. Developments in biotechnology, the evolution of alternative food supply networks, innovations in the food sector and competition policy are likely to affect technical and scale efficiency of food manufacturing firms. Results unraveling the effects of technical and scale efficiency on the survival of firms in the food sector are of particular relevance to food policy makers.     

Inequalities of opportunity in the access and use of telecommunication services in Togo

The liberalization of the telecommunications sector in Togo aimed at ensuring access to a better quality of telecommunication services at affordable prices to everyone. While the liberalization policy has increased competition in the sector and reduced significantly telecommunication services prices charged to costumers, statistics on the access and use of telecommunication services in Togo reveal disparities with respect to individuals' socio-economic characteristics which could be an indication of the existence of inequalities of opportunities in the access and use of these services.This paper investigates the inequalities of opportunity in the access and use of telecommunication services in Togo using a parametric approach. The results of estimations indicate that, inequalities of opportunities are larger for men and the elderly than respectively women and youths and are more pronounced in urban areas and regions such as the Plateaux and Savanna regions. Moreover, the circumstance variables such as the ‘place of residence’ and the ‘region’ are the key variables in explaining the inequalities of opportunities in the access and use of telecommunication services in Togo. So, policies toward reducing inequalities of opportunity in the access and use of telecommunication services in Togo should be designed with regards to men, the elderly, and people living in urban areas and regions such as the Plateaux and Savanna regions.     

Foreign Direct Investment,Imports and Innovations in the Service Industry

The paper analyses for the first time empirically the impact of foreign competition due to inward foreign direct investment and imports on the innovation activities using data of German service firms. Based on the hypothesis that foreign competition has a disciplining effect on domestic markets derived from the manufacturing sector, a positive impact can be expected on innovation in the service sector, while other theoretical considerations do not absolutely support this optimistic view. In the empirical analysis, variants of two probit models are estimated for a sample of 2,019 service firms to explain their product and process innovation activities. The results show that both foreign direct investment and imports have highly significant positive effects on product and process innovations. Vice versa, the export and foreign production activities of domestic firms support innovations, too.     

Exploring the structural effects of the ICT sector in the Greek economy: A quantitative approach based on input-output and network analysis

The aim of this paper is to present a quantification approach for the calculation of the ICT sector's structural effects in the economy, focusing on the case of Greece. We construct a composite sector using a hypothetical extraction methodology based on the most recent Greek input-output table and structural business statistics at the national level. Our framework builds on the formal definition of the ICT sector provided by OECD and includes two distinct sub-components, ICT manufacturing and ICT services. In the second stage of this study, we explore the production linkages among ICT services, ICT manufacturing and the rest of the Greek industries using input-output-based and network analysis-based metrics that build on the intermediate transactions of an expanded input-output table of the Greek economy that includes the two sectors. Our empirical findings suggest that the total ICT sector has a major contribution to the Greek economy in terms of GDP and employment, but this is driven mainly by the ICT services component. We further identify that ICT services are more integrated in the Greek production network compared to ICT manufacturing, but their production linkages are underperforming in terms of meaningful contribution to the activity of the rest of the sectors. These results reflect the low integration of digital technologies and can be further embedded in a discussion on the ICT deficiencies of the Greek economy and the need for targeted regulatory and financial interventions.

Fiber vs. vectoring: Limiting technology choices in broadband expansion

The upgrade of legacy infrastructure is a challenging undertaking in general. The underlying issues are especially prominent for telecommunications networks outside of urban areas. Using German micro-level data, we identify the structural determinants for fiber optics deployment and its extent. We also measure the role of technology competition from the existing infrastructures, VDSL-Vectoring and TV-Cable. In this setting and exploiting a natural experiment, a technologically restrictive policy as proposed by the European Commission is found to be ineffective in promoting fiber deployment. Policy interventions in the form of subsidies targeted at specific local infrastructure projects, however, raise the likelihood of fiber deployment by a substantial margin. A targeted, proactive policy approach is therefore needed to overcome structural and geographical disadvantages.     

Being a woman in an ICT job: an analysis of the gender pay gap and discrimination in Spain

Despite policy initiatives aimed at promoting female access to jobs, the information and communication technology (ICT) professions have traditionally been largely monopolised by men. Segregation, gendered stereotypes and environmental factors have a clear impact on educational and professional choices, as well as on working conditions. The spread of ICT to all economic activities has meant that ICT specialists are now to be found everywhere, not only in the ICT sector where many stereotypes related to technical jobs persist. This work aims to analyse the gender wage gap and discrimination in ICT professions, with the emphasis on how working in an ICT-intensive industry might affect that situation. The study uses the Spanish Earning Structure Survey data for 2014, and applies wage decomposition techniques to the wage distribution. The results show that female ICT professionals face unfavorable working conditions, especially in highly qualified jobs and in ICT-intensive industries.     

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.     

Access regulation and geographic deployment of a new generation infrastructure

This paper addresses the impact of regulatory policy on levels of infrastructure deployment and derived welfare in the telecommunications sector. The model considers two potentially coexisting and partially competing technologies (the “old generation network” – OGN – and the “new” generation network – NGN). This framework allows us to show that the “regulation defining access charge in order to maximize infrastructure deployment” is strictly equivalent to the case in which “no regulation applies”. We also derive from the model that these two types of regulation induce higher social welfare, but lower numbers of NGN consumers, compared to the “ex post access prices” regulation. Finally, we show that the level of infrastructure deployment (as well as social welfare and number of NGN consumers) will be highest if both investment and access charge decisions are taken by the welfare maximizing regulator. This suggests that the social optimum will be achieved through a calls-for-tender process that includes deployment and access charge requirements.     

ICT governance: South Africa

Formal ICT governance structures exist although the efficacy of both the regulator and parliamentary oversight committee remain contentious. On the other hand, the Minister of Communications exercises a strong policy oversight that is viewed as not leading to the envisaged growth in competition and investment in the sector. Consumer protection is also weak.     

An experiment on spatial competition with endogenous pricing

Hotelling's (1929) principle of minimum differentiation and the alternative prediction that firms will maximally differentiate from their rivals in order to relax price competition have not been explicitly tested so far. We report results from experimental spatial duopolies designed to address this issue. The levels of product differentiation observed are systematically lower than predicted in equilibrium under risk neutrality and compatible with risk aversion. The observed prices are consistent with collusion attempts. Our main findings are robust to variations in three experimental conditions: automated vs. human market sharing rule for ties, individual vs. collective decision making, and even vs. odd number of locations.     

Intangible capital,ICT and sector growth in China

This paper explores how intangible capital affects the growth of ICT-intensive sectors in China by examining 29 sectors in 30 regions for the years 2003–2015. It is shown that the value added in ICT-intensive sectors in China will grow faster in regions with faster development of intangible capital. This effect is robust to alternative measures of intangible capital and ICT intensity indicators, and even if other region-level determinants of sector growth such as human capital, non-ICT physical capital and financial market development are taken into consideration. The findings imply that Chinese policy makers should aim for not only more ICT investment but also the development of intangible capital.     

Efficient division of profits from complementary innovations

Many products—including microprocessors, telecommunications devices, computer software, and on-line auction services—make use of multiple technologies, each of which is essential to make or sell the product. The owner of one technology benefits from the existence of complementary technologies. We show that, despite this externality, the structure of payoffs that support efficient R&D investment by duopolists racing to discover a single innovation generalizes to the structure that supports efficient investment for complementary innovations. The paper also examines how alternative intellectual property regimes and legal institutions affect R&D investment in complementary technologies. The results have policy implications for the organization of R&D, the assessment of damages for patent infringement, and allocations of value in patent pools.
