Evaluating the efficiency change and productivity progress of the top global telecom operators since OTT's prevalence

The telecommunications industry has undergone significant evolvement from fixed to mobile substitution (FMS) to fixed mobile convergence (FMC) and now to over-the-top (OTT) services due to the huge rise in data usage. This paper explores efficiency variation during the period 2012–2017 for the top 41 global telecom operators in Forbes Global, 2000. Based on the data envelopment analysis (DEA) meta-frontier approach to reflect differences in production functions, the empirical results herein show that the number of operators achieving technical efficiency with respect to the meta-frontier fell from 13 firms in 2012 to 10 firms in 2013 to 8 firms in 2014 to 8 firms in 2015 and then to 7 firms in 2016, but then rose to 11 firms in 2017, displaying the impact from rise in OTT. For the mobile-only group, the average technical efficiency with respect to the meta-frontier is 0.841, which is superior to the fixed-mobile group's 0.774 and the fixed-only group's 0.714, and the group difference is significant among the three facilities-based groups. The meta-frontier estimation suggests that the fixed-mobile group has the highest meta-technology ratio (MTR) of 0.901 versus the mobile-only group's 0.886 and fixed-only group's 0.718. The empirical results offer policy implications for regulators to encourage telecom operators to have fixed-mobile operations. We further suggest that telecom operators cooperate with OTT service providers and invest in them in order to take advantage of people's more personalized digital life.     

Competition reform and household welfare: A microsimulation analysis of the telecommunication sector in Ethiopia

This paper presents a novel simulation method for estimating the likely welfare effects of policy reforms aimed at increasing competition in strategic economic sectors such as mobile phone services. The proposed method relies on a partial equilibrium simulation approach and estimates the welfare impacts on current consumers and the potential welfare effects among new consumers brought into the market by changes in prices due to competition. This approach is applied to the information and communication technology (ICT) sector in Ethiopia, one of the three countries in the world with a monopoly in the market for mobile phone services. Based on household budget survey data for 2015/16 and departing from a baseline reform scenario that dilutes the market share of the state-owned monopoly to 45 percent, the simulation model estimates a 25.3 percent reduction in the price of mobile services and an increase in 5.7 million new users of mobile services. The predicted drop in prices and increased users would generate a combined relative welfare gain of 1.18 percent (1.09 percent among current users and 0.09 percent among new users), that could be translated into a 0.31 percentage point decline in the national poverty rate and equivalent to lifting about 275,000 people out of poverty. Alternative reform scenarios that dilute the market share of the monopoly to 75 percent and to 30 percent are expected to reduce poverty rate in 0.13 and 0.52 percentage points, respectively. The method proposed in this study represents a useful tool for promoting competition reforms in developing countries, particularly in sectors known for excluding significant segments of the population because of high consumer prices.     

Understanding the trend to mobile-only internet connections:A decomposition analysis

A growing portion of internet users rely solely on mobile devices such as smartphones for their online access. The percentage of “mobile-only” households increased from 9% in 2011 to 20% in 2015, more than doubling in only four years. As this shift continues, it leads to the question of what factors are driving the rise in mobile-only adoption. Using nationally representative data, this study uses logistic regressions and a decomposition technique to understand the trend. The decomposition reveals that a significant portion (65%) of the growth was due to an increase in the download speeds of mobile networks. An increased acceptance of mobile-only access by households aged 55 and older was also partly responsible. Understanding (and developing a response to) the trend towards mobile-only adoption will be important as organizations and governments continue to work to close the digital divide.     

Consumers’ valuation for food traceability in China: Does trust matter?

Food safety is a very important topic in China. We investigate Chinese consumers’ preferences and willingness to pay (WTP) for food traceability using a choice experiment. Given that consumers’ trust in the food system may affect their preferences and WTP, we also assess the interaction between consumers’ trust in government’s supervision of food safety and food labels and consumers’ preferences for traceable food products. Using data collected from a choice experiment on Fuji apples in a face-to-face survey in six Chinese cities, the results show that (i) consumers are willing to pay for traceable food but their valuations can differ upon the degree of their trust in government’s supervision of food safety and food labels; (ii) consumers are willing to pay for traceability with strong evidence of preference heterogeneity; (iii) government is not the most trusted safety inspection and certificate authority as found in prior studies using animal food products in China.     

Comparing consumer preferences for color and nutritional quality in maize: Application of a semi-double-bound logistic model on urban consumers in Kenya

Consumer preferences for white maize in East and Southern Africa concerns developers of maize biofortified with provitamin A carotenoids, since carotenoids impart a yellow or orange coloration. Urban consumers’ willingness to pay (WTP) for yellow maize was estimated, using a semi-double-bounded logistic model, based on a survey of 600 maize consumers in Nairobi, Kenya, at posho mills, kiosks and supermarkets. Consumers showed a strong preference for white maize. Only a minority would buy yellow maize at the same price as white maize, and fewer consumers in the posho mills (24%) and kiosks (19%) than in the supermarkets (34%) would do so. On average, consumers need a price discount of 37% to accept yellow maize. This discount was less at the posho mills (35%) and kiosks (37%) than in the supermarkets (48%). Most respondents (76%) were aware of the existence of fortified meal and the generally showed an interest. The average premium for fortified maize was much less than the discount for yellow: 5.9% for those aware and 7.4% for those unaware. Consumer preferences were influenced by socioeconomic factors such as gender, education, income and ethnic background. Women have a stronger preference for both white maize and fortified maize than men, and consumers with more education have a stronger preference for white. Income decreases the WTP for yellow maize as well as the price elasticity, but increases the WTP for fortified maize. Consumers originating from Western Kenya have a lower preference for white, while those from Central Kenya had a stronger preference for fortified maize.     

Estimating consumer surplus in the mobile telecommunications market: The case of Korea

This paper estimates consumer surplus in the Korean mobile telephone services (MTS) market. The Korean mobile telecommunications market has grown rapidly since 1997 when competition was introduced and Code Division Multiple Access (CDMA) technology was commercialized. Because consumer surplus is relevant to the controversy over establishing an appropriate price level between consumers and service providers, the need for a robust measurement of benefit from MTS is increasing. The measured net consumer surplus estimated by means of elasticities of demand reached about US$48.8 billion in the period 1996–2004 and the changes amounted to about US$8.8 billion during the same period. In particular, after competition was introduced into the market with an accompanying price decrease and increase in the number of subscribers, consumers have benefited greatly. Therefore, it can be inferred that a facility-based competition policy and the reduction in price of access such as handset subsidies all played a positive role in the early diffusion of MTS in Korea. The estimated consumer surplus in this paper does not include network externality (option externality); if this were considered, the total social welfare of the consumer would be larger.     

移动健康“玩”起来

移动健康行业开始尝试“游戏化”的方式,希望将顾客转变成粉丝,将健康过程变成一种享受。 移动健康（mHealth）概念自2007年被首次提出后,就犹如移动互联世界的“一匹黑马”——GSM协会最近在开普敦举办的移动健康峰会上预计,到2015年,移动健康所涉及的广泛电子健康市场,规模有望达到1600亿美元。不过要想在这个产业中分食一样羹,参与者还有许多脑筋要动。例如,以什么方式能够让人们主动提交他们所有的健身和健康数据？有什么办法可以增进用户与产品之间的感情,提升他们的参与度并留住他们？     

Consumer willingness to pay for traditional food products

Reflecting the growing interest from both consumers and policymakers, and building on recent developments in Willingness to Pay (WTP) methodologies, we evaluate consumer preferences for an archetypal traditional food product. Specifically we draw on stated preference data from a discrete choice experiment, considering the traditional Hungarian mangalitza salami. A WTP space specification of the generalized multinomial logit model is employed, which accounts for not only heterogeneity in preferences but also differences in the scale of the idiosyncratic error term. Results indicate that traditional food products can command a substantial premium, albeit contingent on effective quality certification, authentic product composition and effective choice of retail outlet. Promising consumer segments and policy implications are identified.     

Telecommunications services and economic growth: Evidence from India

This paper estimates the growth contributions of telecom services by public and private sectors and distinguishes it from the information technology services. Socio-economic determinants of demand for telecom services are estimated for fixed and mobile phones in the framework of a Logit model and using data from a small-household sample survey in India. Estimation results show a significant negative impact of price and a positive impact of income variables; distinguish the importance of social caste, education level, nature of occupation, age of household head and family size between fixed and mobiles phones and offer evidence for substitutability of mobile phones for fixed phones. These results add to the empirical knowledge of socio-economic determinants of telecom demand and have implications for selective design of policies towards promotion of higher demand and attainment of higher economic growth by fixed and mobile services in India and other developing countries.     

Switching mobile operators: Evidence about consumers’ behavior from a longitudinal survey

The rate at which consumers switch providers is a key indicator of the level of competition among mobile telephone operators. This paper uses a longitudinal survey of 4110 mobile users in Spain in 2015 and 2016 to analyze what drives consumers’ decisions to switch mobile operators. After controlling for a number of individual characteristics, including gender, age, education level and employment status, switching was found to be significantly less common among satisfied customers and those whose mobile service was bundled with fixed services. Moreover, the more complex the bundle was, the lower the rate of switching was. Considerable consumer inertia was also found: inattentive consumers and those who had not switched previously were much less likely to switch. The implications of these results for regulators and operators are discussed.     

How does income inequality affect market outcomes in vertically differentiated markets?

The distribution of consumer incomes is a key factor in determining the structure of a vertically differentiated industry when consumer's willingness to pay depends on her income. This paper computes the Shaked and Sutton (1982) model for a lognormal distribution of consumer incomes to investigate the effect of inequality on firms' entry, product quality, and pricing decisions. The main findings are that greater inequality in consumer incomes leads to the entry of more firms and results in more intense quality competition among the entrants. More intense quality competition raises the average quality of products in the market as firms compete for the shrinking share of higher-income consumers. With zero costs of quality improvements and an upper bound on the top quality or when costs of quality are fixed and rise sufficiently fast, greater heterogeneity of consumer incomes also reduces firms' incentives to differentiate their products. Competition between more similar products tends to reduce their prices. However, when income inequality is very high, the top quality producer chooses to serve only the rich segment of the market and charges a higher price. The conclusion is that income inequality has important implications for the degree of product differentiation, price level, industry concentration, and consumer welfare.     

Assessing holistic economic value for multifunctional agriculture in the US

This study used contingent valuation method to shed light on public preferences on the multifunctional roles of the US agriculture and to present a holistic estimate of the economic value of the nonmarket goods and services of US agriculture. Contingent valuation survey instrument was administered to a sample composed from the Ipsos web-based panel. Fishbein’s model of reasoned behavior and mediation hypothesis were combined to model the relationship between WTP (behavioral intentions) and sets of explanatory variables including attitudes, perceived attributes (about family farms, farmland preservation programs, government involvement in agricultural markets, and ecological state of our world), and socio-demographic profiles. Results show that, while exerting a highly significant impact on WTP, attitudes mediate the effects of the attribute variables on WTP: i.e., the attributes influence WTP directly as well as indirectly through attitudes. The estimated mean WTP was $515 per taxpayer annually. Aggregating individual WTPs across the US taxpayers above 20 years old produces $105 billion, representing a crude estimate of the economic value that the US consumers place on the multifunctional roles of US agriculture.     

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.     

Competition in Korean mobile telecommunications market: business strategy and regulatory environment

After the launch of PCS in 1997, the Korean mobile telephony market achieved a remarkable subscriber base growth. The market is composed of a differentiation advantage seeker, SK Telecom; a cost advantage seeker, LG Telecom; and three other carriers: Hansol PCS, Korea Telecom Freetel, and Shunsegi Telecom that do not show clear adherence to any type of advantage. Despite large growth in subscribers, price competition has not occurred after the competition except in handset subsidies. New restrictions on handset subsidies, closing the only door for price competition, favored a differentiation seeker at the expense of a cost advantage seeker. The Ministry of Information and Communication’s provisional plan for quality evaluation without price deregulation runs the risk of quality over-provision that is sub-optimal, and may further distort the business performance of carriers. Overall complete deregulation is necessary, in order to enhance the competitiveness of the Korean mobile telephony industry and to increase consumer welfare.     

Impacts of handset bundling on mobile data usage: The case of Finland

Promotion of the adoption of new services has emerged as a possible driver for the regulation of handset bundling and subsidies. Handset bundling, however, has complex implications not only on mobile data service adoption, the focus of this research, but also more broadly on the mobile market dynamics. Due to the complexity, regulators have difficulties in anticipating the possible resulting impacts. Using a case study, expert interviews, and usage measurements as research method, an empirical framework was constructed to make the service usage impacts more explicit. The framework enables the identification of the regulator's steering options and their qualitative impacts. Results are based on observations before and after the change of law on handset bundling in the Finnish market. According to the findings, handset bundling regulation is a possible but risky tool for steering the market.     

Fixed-to-mobile substitution in the European Union

This paper analyzes substitution between access to fixed-line and mobile telephony in the European Union using cross-section panel data on households’ choices of telecommunications technologies in years 2005–2010. We estimate a structural model of household?s demand for access to: (i) fixed-line only; (ii) mobile only; and (iii) both fixed-line and mobile. We find that growing Internet usage increases the share of ‘fixed + mobile’ households, which suggests that households keep their fixed-line connection to access Internet. However, the spread of 3G and cable broadband access decreases the share of ‘fixed + mobile’ households and increases the share of ‘mobile only’ households. Hence, fixed-to-mobile substitution was slowed down by the spread of Internet but it may continue with the spread of mobile broadband. Furthermore, bundling of telecommunications services increases the share of ‘fixed + mobile’ households and decreases the shares of ‘mobile only’ and ‘fixed only’ households. Therefore, operators which can bundle fixed-line connection with Internet or mobile services may slow down fixed-to-mobile substitution.     

Me and you and everyone we know: An empirical analysis of local network effects in mobile communications

This paper investigates the importance that consumers assign to local network effects, i.e. the extent to which they take account of their contacts’ mobile operators when choosing a provider for themselves. The authors identify individual characteristics that affect the importance consumers attach to local network effects. The study relies on a survey of 193 Italian students. The results show that consumers are highly heterogeneous with respect to the importance they give to the operators chosen by their friends/family members in choosing which provider to use. This heterogeneity is associated with individual innovativeness and patterns of mobile phone usage. For instance, consumers who are more interested in local network effects are typically more-aware users, who use voice services quite intensively. These consumers, who pay attention to local network effects, spend comparatively little proportional to the intensity of their mobile usage.
