Pricing of mobile phone attributes at the retail level in a developing country: Hedonic analysis

This study has been undertaken to determine the effect of mobile phone attributes on their retail market prices. A log-linear hedonic price model was fitted to a total of 348 handsets, for which data were collected about various attributes from different websites, while the price data were obtained from mobile phone retailers in two major cities of Pakistan from November 2016 to February 2017. Results indicate that brand, battery capacity, weight, operating system, RAM, memory size and display size have a significant positive effect on mobile phone prices. Given the significant premium associated with various characteristics, manufacturers need to formulate strategies to emphasize the battery capacity of 2000-3000?mAH, RAM of more than 1GB, screen size of more than 5 inches, memory size of more than 8GB, back camera of over 15MP, 4G network mode, front camera and FM radio.

Quality-adjusted international price comparisons of mobile telecommunications services

Many countries' policymakers have conducted international price comparisons of mobile telecommunications services to prevent service operators from overcharging subscribers. However, those comparisons have become more complicated because of the escalation in service usage and telecommunications expenditures spurred by the proliferation of smartphones and broadband LTE wireless internet service networks. The basket-based methodologies that have been widely used for international price comparisons are also limited—first, because the baskets for comparison may not be representative of actual service usage patterns in some countries; second, because they are difficult to apply to highly differentiated service plans due to the significant increase in wireless internet service usage and widely used plans with unlimited voice call service and SMS/MMS; and third, because they cannot consider the quality of service, such as upload and download speed in various service environments, at all. As an alternative, this paper proposes a hedonic pricing model that accounts for service quality and its variation in potentially disruptive environments, as well as fixed charge for a mobile phone additional to the price of service plans. The model was used to derive quality-adjusted price indices of mobile telecommunications services for twelve cities in ten countries with broadband LTE wireless internet service. The empirical results confirmed that the price index of each city varied significantly across the specifications,—both within the United States and internationally—depending on whether the model was constructed to reflect service quality and its variation on roads, in buildings, and in subways. The price index of each city also varied depending on whether the subsidized price of a mobile phone was considered part of the monthly price of a service plan. These results have important implications for policymakers seeking to understand the ultimate level of mobile telecommunication service prices for their country in a global context.     

Is better access to mobile networks associated with increased mobile money adoption? Evidence from the micro-data of six developing countries

In several developing countries in Sub-Saharan Africa, accessibility to digital financial services is increasing because of the development of mobile money services. People previously excluded from the financial system have started to have access to financial services such as receiving and sending remittances, saving, and borrowing. This study examines the effect of network accessibility on the use of mobile money in six developing countries (Bangladesh, Kenya, Nigeria, Pakistan, Tanzania, and Uganda) using GPS information on each household and mobile phone network coverage maps. We find that among these six countries, network accessibility is associated with the use of mobile money in a robust way only in Pakistan and Tanzania. In those two countries, when a household location becomes 10 km closer to the center of the area with multiple mobile networks, the probability of using mobile money increases by 10 percent. In the other countries, we did not find a robust relationship between the use of mobile money and network accessibility. This suggests that increasing network accessibility may not be an efficient method for increasing mobile money adoption in certain countries. The fact that mobile money use rates differ between Tanzania and Pakistan also suggests that the effect of mobile networks is unrelated to the overall level of mobile money adoption.     

Predation and network based price discrimination in Chile

This paper uses a model of strategic interaction among firms –that set discriminatory and nonlinear prices– in addition to public information on prices of the plans marketed by the three major mobile phone companies, to assess the extent to which on-net/off-net price differentials in the plans they offered could represent predatory practices in the mobile telephony market in Chile. The results show that the largest companies offered a few plans with an off-net/on-net price differential larger than what a competitive theoretical model predicts. This larger differential is consistent with the notion of predation defined by Hoernig (2007) as reducing a competitor's profits. Despite the fact that these plans were a small fraction of all the plans mobile phone firms offered, they were recently banned by the antitrust authority because of their potential anticompetitive effects.     

The emerging value network in the mobile phone industry: The case of Japan and its implications for the rest of the world

This paper considers how the mobile phone industry is changing from a value chain to a value network using the Japanese market as an example. Value networks involve a larger number of firms, a more complex set of relationships between them, and agreements on a greater number of interface standards than do value chains. Building from this concept of a value network, the paper shows how: (1) agreements on many of these interface standards are enabling connections to be made between the mobile phone and other industries; (2) the resulting products and services often reflect the technological capability of phones and the existing products and services in these “other” industries; (3) each new interface standard requires a new critical mass of users; and (4) a critical mass of users for a new interface standard partly builds from previously created critical masses of users. On a practical level, this paper's analysis adds to a growing list of evidence that the growth in Western mobile Internet markets is nowhere near its potential and that the change from a value chain to a value network requires a different form of standard setting, policy making, and management than are currently used in the mobile phone industry.     

Competition between multiple asymmetric networks: Theory and applications

This paper presents a tractable model of network competition with many firms, elastic subscriber demand, off-net price discrimination, call externalities, and cost and market share asymmetries. We characterize stability in expectations and equilibrium under firm- and market-level network effects. The model is applied to simulate the effects of termination rates, market maturity, and retail pricing strategies. We show that predictions based on duopoly models can be misleading, in particular concerning the effects of termination rates.     

Vertical Ownership,Program Network Carriage,and Tier Positioning in Cable Television: An Empirical Study

Using a 2004 cross-sectional database of digital cable systems in the U.S., we provide new evidence that the effects of vertical ownership ties between systems and programming suppliers persist in spite of extensive channel capacity expansion, as well as new competition from direct broadcast satellites. Focusing on four program network groups (basic outdoor entertainment, basic cartoon, basic movie, and premium movie), we generally find that integrated cable systems carry their affiliated networks more frequently and carry unaffiliated rival networks less frequently—a pattern identified by previous studies using data prior to DBS or the capacity expansion effects of digital cable. We also find that integrated systems that do carry rival networks often position them on digital tiers having more limited subscriber access, a pattern not investigated in previous studies.     

Hedonic prices in the German market for mobile phones

This paper provides a hedonic price analysis of mobile telephones for the German market, based on data of 302 different handsets from 25 manufacturers over the period from May 1998 to November 2003. By measuring shadow prices for different product characteristics, the authors find that volume, for example, has a negative effect on the price of a mobile handset, while the number of ringtones and the talk time battery life relative to the handset's weight positively affect mobile phone prices. Perhaps somewhat surprisingly, radiation is statistically insignificant. Also handsets have become cheaper over time, and handsets with additional features, such as MMS, MP3 or Bluetooth, command a higher price. In addition, there are positive brand name effects for some brands. According to the estimations presented in this paper the brand name premiums may range from 57 to 172 euro.     

An estimate of the average cumulative royalty yield in the world mobile phone industry: Theory,measurement and results

An influential literature argues that dispersed patent ownership may lead to royalty stacking and excessive running royalties, thus increasing the long-run marginal cost of manufacturing phones and their prices. One set of estimates claims that the royalty stack is on the order of 20–40 percent of the value of the average phone. In order to assess this claim, we estimate the average cumulative royalty yield—the sum total of patent royalty payments earned by licensors, divided by the total value of mobile phones shipped— in the world mobile phone industry between 2007 and 2016.We “follow the money” and identify, with varying accuracy, 39 potential licensors in the smartphone value chain. We find that, of these, only 29 charged royalties in 2016, running from a low of $1.6 million to a high of $7.7 billion, summing to $14.2 billion in total, which compares with $425.1 billion in mobile phone sales. The average cumulative royalty yield in 2016 was 3.3 percent or $7.20 per phone. If we restrict this only to smartphones, the result would be $9.60 per phone, roughly 3.4 percent of the average selling price. A sensitivity analysis shows that even under a very restrictive set of assumptions, the average cumulative royalty yield on a smartphone would not exceed 5.6 percent.     

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.     

Characteristics and mobile Internet use intensity of consumers with different types of advanced handsets: An exploratory empirical study of iPhone,Android and other web-enabled mobile users in Germany

This work explores personal characteristics and mobile Internet (MI) use behaviors of consumers equipped with four distinct types of advanced handsets for accessing the Internet via cellular radio infrastructures of mobile network operators (MNO). Furthermore, it investigates the extent to which personal and mobile appliance characteristics explain variance in actual MI use intensity. Data on two demographic variables, three MNO relationship characteristics and actual MI use intensity (average monthly volume of mobile IP traffic generated by a subscriber in May and June 2011) of 9321 adult consumers with a flat MI pricing scheme are extracted from customer files of the German subsidiary of a large international MNO. 959, 2213, 2410 and 3739 of the sample members use an Apple iPhone 3, an Apple iPhone 4, a model running with Google’s Android operating system (OS) and other MI-enabled mobile OS/phone types, respectively. Compared to the adult population in Germany, persons at least 50 years of age are clearly underrepresented among MI adopters with the four studied device types. Differences between the four phone type groups with regard to gender, age, time from enrollment and MI use experience emerge as statistically significant, but they achieve only minor substantial relevance. MI use intensity is highly positively skewed: In each of the four appliance groups, a small number of users disproportionately add to the total MI traffic generated by the subjects. Consumers’ advanced OS/handset type strongly contributes towards explaining MI use intensity variance. iPhone subscribers generate more traffic than Android customers who in turn show a higher MI activity level than individuals running other web-enabled mobile models. Age is the only studied personal characteristic consistently showing a (negative) association with MI usage, which both is statistically and materially significant. Conclusions are drawn for MNO on MI marketing issues. Implications of study limitations for research on MI adoption and use behaviors on the MI are also outlined.

Estimating demand for cellular phone services in Japan

Since the 1990s, the telecommunications industry has changed dramatically with the wide diffusion of mobile telecommunications. In spite of this, the nature of the cellular phone market has not yet been explored sufficiently. This paper analyzes the demand for cellular phone services using data on the Japanese cellular phone market in the late 1990s. It finds that the market is highly product-differentiated and conventional network externalities are no longer decisive factors in choosing a mobile phone carrier. The evidence also shows that the demand for cellular phone services is quite price-elastic, with estimated elasticity from 1.30 to 2.43 in absolute value.     

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.     

Business case evaluations for LTE network offloading with cognitive femtocells

Mobile networks are increasingly becoming capacity limited such that more base stations and smaller cells or more spectrum are required to serve the subscribers’ increasing data usage. Among several challenges, the establishment of new base station sites becomes challenging and expensive. This study proposes and analyzes critical aspects of a business case where a mobile operator offloads its mobile LTE network by deploying cognitive femtocells. When aided by a sensor network the cognitive femtocell will be able to use frequencies other than the mobile network and hence increase its power to cover outdoor areas and neighbour buildings. This cognitive femtocell strategy will be compared with an alternative strategy where an operator deploys conventional femtocells and has to build additional base stations to meet the traffic demands. The business case analysis illustrates that there is a potential for cost savings when offloading the mobile network with cognitive femtocells when compared to the alternative strategy. It must be emphasized that the studied concept is innovative and that the business case period starts in 2017, hence, parameter assumptions are uncertain. Therefore, as the most important message of this work, sensitivity analysis is used to reveal the most critical aspects of the cognitive femtocell business case. It is found that the most critical parameters regarding the cognitive femtocell are the price for backhauling, the number of users supported and the coverage. Furthermore, an optimal coverage radius for the cognitive femtocell for lowest possible costs is found. Costs related to the fixed sensor network are found to be less critical since sensors are embedded in the cognitive femtocells. Sensitivity analysis is also presented for spectral efficiency, cognitive and conventional femtocell offloading gain, sensor density and price, customer density and price for base station site establishment.     

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.     

Coordination in inter-network co-opetitition: Evidence from the tourism sector

In this paper, we investigate whether and to what extent formal governance forms such as contracts are a necessary condition to manage coopetitive interactions among networks. We situate our analysis within the tourism sector where we gain insights from an in-depth exemplar case of co-opetition among nearby Italian tourism destinations conjointly developing and marketing an event, the Pink Night Festival. We suggest that coordination mechanisms with varying degrees of formality seem to play a crucial role to manage coopetitive interactions. Subsequently, we identify eight key drivers of formalization of coordination mechanisms in inter-network co-opetitition: 1) leadership; 2) brokerage and pivotal attitude; 3) power asymmetry; 4) focus on strategic thinking; 5) maturity of network management approach; 6) maturity and distance of the marketing approach; 7) past experience working together; 8) cultural, functional and organizational similarities. Last, we develop a conceptual framework highlighting that each stage of the evolution of an inter-network coopetitive relationship has key features in terms of the underlying coordination mechanisms.     

Network effects and preference heterogeneity in the case of mobile telecommunications markets

This paper demonstrates how revealed- and stated-preference analyses can be used for modeling network effects in the field of mobile telecommunications. The aim of this study was to verify if network effects may still play a role in the Polish mobile telecommunications market, measure their strength, identify their sources and variability across consumers by accounting for consumers' observable and unobservable preference heterogeneity, evaluate their monetary value to consumers, and finally, to verify if the marginal utility associated with network effects is constant. The analysis of consumers' revealed choices (currently used mobile telephone operator) allowed the identification of major differences between customer bases of incumbent and new entrant operators, and insight into the business strategies adopted in the presence of asymmetric regulation of mobile termination rates. The second part of the study—the analysis of the consumers' stated choices (made in carefully prepared and designed hypothetical choice situations, known as the choice experiments) made it possible to directly model consumers' utility functions and, in this way, investigate the nature of network effects in mobile telecommunications markets. From the results, the presence of strong network effects, which are related to the ratio of consumers' social network group using the same operator, and to the magnitude of on-net price discounts, is confirmed. These network effects can be disaggregated to pecuniary and non-pecuniary effects. Through the utilization of the random parameters multinomial logit model, consumers' observable and unobservable preference heterogeneity can be accounted for, which proved a scientifically revealing and potentially policy-relevant approach. The results might be of a particular interest to other researchers aiming at modeling consumers' preferences as well as to mobile telephone operators and regulatory authorities—it is shown that capacity for vigorous price competition between mobile operators is limited by non-price factors, which affect subscriber's choices, especially in the presence of asymmetric mobile termination rates.
