Demand for telecommunication services in developing countries

Living standards and economic growth in developing countries are invariably linked to the availability and use of telecom services. Effective policy decisions require the best estimates of the drivers of these services. In this paper, telecommunications demand is estimated in models for residential mainline and mobile telephone service for developing countries for the period 1996–2003. The paper tests for cross-price effects between mainline and mobile service and its findings have important policy implications. It finds residential monthly price elasticity to be insignificant for developing countries, but the connection elasticity is larger than generally found in the literature. Mobile monthly price elasticities are very large. A new and important empirical finding is that although wireline phones are substitutes in the mobile market, the contrary is not true—mobile phones are not substitutes in the wireline market, and in fact may be considered complements. This lack of symmetry has important implications for properly defining telecom markets. Universal service subsidies and competitive market initiatives should be reevaluated in light of the paper's elasticity estimates. Increased competition, income growth and enhanced education may be the ultimate universal service promoters.     

Investigation of factors affecting the diffusion of mobile telephone services: An empirical analysis for Vietnam

This paper analyzes the diffusion of mobile telecommunications services in Vietnam and examines how telecommunications regulation and potential substitute/complement services affect the growth of the number of mobile telephone subscribers. Using a logistic diffusion model, it is found that fixed telephone services are a complement while data services have a negative relation to mobile telephone services in Vietnam. As for regulation, the policy of introducing competition has been found to be the most effective in influencing the adoption of mobile services. Another important result is that the estimated potential market is roughly 76% of the total population. The findings suggest that suitable regulation that guarantees competition in the mobile telecommunications market in a developing country such as Vietnam is one of the most important factors for a positive diffusion process.     

Leveraging the EU regulatory framework to improve a layered policy model for US telecommunications markets

What is the best way to overhaul the current telecommunications legislative framework in the United States? This is an ongoing debate among telecom policy analysts and many others affected by the legacy of regulatory compromises that govern US telecommunications (and related information and media) industry sectors. This paper compares a Layered Model for US telecommunications policy with the regulatory framework adopted by the European Union. Both approaches focus on service characteristics rather than underlying technological traits.¹ It becomes clear that the Layered Model could be adopted to move away from sector-specific regulation, and could successfully use conventional market analysis criteria.     

Multihoming, content delivery networks, and the market for Internet connectivity

Peering points between different Internet service providers (ISPs) are among the bottlenecks of the Internet. Multihoming (MH) and content delivery networks (CDNs) are two technical solutions to bypass peering points and to improve the quality of data delivery. So far, however, there is no research that analyzes the economic effects of MH and CDNs on the market for Internet connectivity. This paper develops a static market model with locked-in end users and paid content. It shows that MH and CDNs create the possibility for terminating ISPs to engage in monopolistic pricing towards content providers, leading to a shift of rents from end users and content providers to ISPs. Implications for future innovations are discussed.     

Implementing policy on next-generation broadband networks and implications for equity of access to high speed broadband: A case study of Australia's NBN

Next generation telecommunications infrastructure is expanding and supporting rapid growth of broadband technologies and a digital economy. In this context, digital information and communications technologies (ICTs) are of increasing importance as a means for people to gain access to health or social services, employment opportunities, information and social networks. In this article we draw on our recent case study research to examine the policy (and politics) shaping implementation of Australia's National Broadband Network (NBN) and its likely effects on equity of access to high speed broadband (HSB) services. We monitored NBN policy and implementation from 2015 to 2018 through policy documents, reports, and media. To assess likely effects of NBN policy on implementation and subsequently on equity of access to HSB we: a) applied a framework defining four elements of equity of access; and b) analysed stakeholder views drawn from media articles and 22 interviews with experts on NBN policy including politicians, government staff, and industry representatives. We found that equity considerations competed with political and commercial imperatives during the rollout of the NBN. This resulted in positive and negative consequences for equity of access to HSB, with a change in policy and implementation in 2013 bringing greater risks to equity of access. The case study provides a framework for considering equity in the implementation of next generation telecommunications infrastructure and highlights the importance of considering equity in the evaluation of telecommunications infrastructure.     

Using the Hicks formula to evaluate an estimate of the elasticity of derived demand for toll-free numbers

Duffy-Deno & Parsons D-D & P (2012) estimated the coefficient for the price elasticity of demand for toll-free numbers (TFNs) at between −0.04 and −0.05. Here, the Hicks formula for derived demand is used to check the range of likely demand elasticity for TFNs given the special characteristics of this market. This approach suggests that the demand for TFNs is likely not more elastic than estimated by D-D & P. Therefore, the premise is sound for D-D & P's discussion of the public policy implications of highly inelastic demand for TFNs. The use of industry information for all four parameters of the Hicks formula to check a derived demand elasticity is the first of its kind in the published literature.     

Friending the taxman: On the use of social networking services for government eID in Europe

The provision of identities online continues to be a fiercely debated topic in policy circles, with proposals emerging for public sector organizations to leverage pre-existing social networking services for their own identity management purposes. Within the broader context of private sector organizations springing up as identity providers, this article explores — from a socio-legal perspective — the merits and drawbacks of using social networking services for government eID in Europe. It then reviews the present and future European policy environment concerning official use of social networking credentials. We focus specifically on legislative measures currently being proposed in the EU to facilitate the Identification, Authentication and Signature policy, within the scope of the ongoing Electronic Signatures Directive revision process and the launch of the proposed Electronic Trust Services Regulation.     

Testing alternative theories of the firm: transaction cost,knowledge-based,and measurement explanations for make-or-buy decisions in information services

Firms boundary choices have undergone careful examination in recent years, particularly in information services. While transaction cost economics provides a widely tested explanation for boundary choice, more recent theoretical work advances competing knowledge-based and measurement cost explanations. Similar to transaction cost economics, these theories examine the impact of exchange attributes on the performance of markets and hierarchies as institutions of governance. These theories, however, offer alternative attributes to those suggested by transaction cost economics or offer alternative mechanisms through which similar attributes influence make–buy choices. Traditional empirical specifications of make–buy models are unable to comparatively test among these alternative theories. By developing and testing a model of comparative institutional performance rather than institutional choice, we examine the degree of support for these competing explanations of boundary choice. Hypotheses are tested using data on the governance of nine information services at 152 companies. Our results suggest that a theory of the firm and a theory of boundary choice is likely to be complex, requiring integration of transaction cost, knowledge-based, and measurement reasoning. © 1998 John Wiley & Sons, Ltd.

Willingness to pay for over-the-top services in China and Korea

The increasing penetration of broadband and multiscreen availability has encouraged the development of premium video consumption through over-the-top (OTT) services. Netflix, the leading global OTT provider, is aggressively expanding its international operations and has ambitiously entered the Asian market. To prepare for the shift that the streaming service giant will bring, a proper understanding of consumer acceptance and intent to pay for OTT services is crucial. Therefore, this empirical study uses conjoint analysis to investigate the key attributes and to examine consumers’ marginal willingness to pay (WTP) for OTT services. We identified recommendation systems, resolution, and viewing options as important product attributes of OTT services that influence the WTP of Chinese and Korean consumers. The most important attribute for Chinese consumers of OTT services was resolution, followed by the recommendation system and viewing options. For Korean consumers, the recommendation system was ranked as the most valuable attribute, followed by viewing options and resolution. The overall WTP of Chinese consumers was 22.6 yuan (3.4 USD) per month, while Korean consumers’ intent to pay amounted to a total of 3530 won (3.1 USD) for OTT services.     

Consumers’ willingness to pay for eco-friendly apples under different labels: Evidences from a lab experiment

An experiment was conducted in France to evaluate the impact of health and environmental information on consumers’ choices between conventional and organic apples. Results show that additional and precise messages about both pesticides use and pesticides residues significantly impact consumers’ choices between both products. The experiment also studied the effect of a new label signaling apples that only use few pesticides compared to conventional apples. With elicited willingness-to-pay, we show that the introduction of this new label increases the average participants’ surplus whatever the information context for participants, because of a higher quality compared to conventional apples and a lower price compared to organic products. In order to complement this label, a minimum-quality standard imposing the use of few pesticides is socially optimal when initial participants’ knowledge is limited.     

Combining participatory crop trials and experimental auctions to estimate farmer preferences for improved common bean in Rwanda

Participatory crop improvement raises the prospects for developing seed varieties that meet the needs of subsistence farmers but may face challenges regarding preference elicitation, particularly in complicated policy environments. We integrate binding experimental auctions with participatory variety selection to elicit farmers’ preferences for improved common bean varieties in Rwanda. We find that auctions reveal farmer preferences more accurately than stated nonbinding rankings in this context and that participatory on-farm crop research is essential to understanding how farmers evaluate tradeoffs between multiple crop attributes. We also find that farmers highly value intercrop yield despite government policy that encourages farmers to monocrop.
