    The Japanese mobile market has recently shown a remarkable growth in the last decade, with more than 106.2 million 3G (3rd Generation, or W-CDMA) subscribers and 4.4 million 2G (2nd Generation, or PDC) as of December 2009. This paper attempts to analyze factors promoting Japanese mobile phone, focusing on 3G technologies. Factors promoting it can be summarized as follows: (1) deregulations by government, such as MNP (Mobile Number Portability) and collocation; (2) competition among carriers, such as introduction of new charge plans; (3) technological development, such as connection speed; and (4) contents and applications. This paper utilizes the panel data of three main carriers of the mobile phone market, namely, NTTdocomo, au (KDDI), and Softbank. As for a model for estimation, we apply that of Madden and Coble-Neal [2004] which studied the relationship between fixed and mobile phone with the panel data by the dynamic random effects estimation. Dynamic models are based not only on the assumption such that carriers do not instantaneously adjust to satisfy their long-term demand but also on network externalities. Besides, the paper applies a dynamic panel data model in order to take care of the endogeneity problem. This paper deals with this problem rigorously by applying Arellano-Bond estimator (Arellano and Bond [1991] and Arellano and Bover [1995]) which estimates exogeneous or predetermined variables, in addition to instrumental variables, using the two-step generalized method of moments (GMM). Based on this framework, this paper identifies service innovations such as entertainment, flat rate charges are found significant for the 3G mobile phone diffusion. --dynamic panel data analysis,competition policy,network externalities,endogeneity,m-commerce,e-entertainment,MNP

    Changes in consumers' behavior when a vertically integrated service is separated —The case of Japanese mobile phone services—

    Get PDF
    In this paper, I empirically examine the consumer behavior change in the case that the current vertically integrated Japanese mobile phone market was separated by employing the stated preference survey. As a hypothetical vertically separated situation, I assumed the introduction of contents compatibility and handsets compatibility among different mobile phone carriers. My analysis also assumed the introduction of mail address portability. My estimation results yield the following implications: (1) handset compatibility, contents compatibility, and mail address portability reduces consumer's switching costs, and (2) current contents incompatibility is offsetting the network quality difference among carriers.Telecom market, Mobile Phone, Switching costs, Vertically Integrated market, Compatibility, Conjoint analysis, Discrete choice model, Mixed logit model

    Every year we see a new dimension of the ongoing Digital Revolution, which is enabling an abundance of information to move faster, cheaper, in more intelligible forms, in more directions, and across borders of every kind. The exciting new dimension on which the Aspen Institute focused its 2006 Roundtable on Information Technology was mobility, which is making the Digital Revolution ubiquitous. As of this writing, there are over two billion wireless subscribers worldwide and that number is growing rapidly. People are constantly innovating in the use of mobile technologies to allow them to be more interconnected. Almost a half century ago, Ralph Lee Smith conjured up "The Wired Nation," foretelling a world of interactive communication to and from the home that seems commonplace in developed countries today. Now we have a "Wireless World" of communications potentially connecting two billion people to each other with interactive personal communications devices. Widespead adoption of wireless handsets, the increasing use of wireless internet, and the new, on-the-go content that characterizes the new generation of users are changing behaviors in social, political and economic spheres. The devices are easy to use, pervasive and personal. The affordable cell phone has the potential to break down the barriers of poverty and accessibility previously posed by other communications devices. An entire generation that is dependant on ubiquitous mobile technologies is changing the way it works, plays and thinks. Businesses, governments, educational institutions, religious and other organizations in turn are adapting to reach out to this mobile generation via wireless technologies -- from SMS-enabled vending machines in Finland to tech-savvy priests in India willing to conduct prayers transmitted via cell phones. Cellular devices are providing developing economies with opportunities unlike any others previously available. By opening the lines of communication, previously disenfranchised groups can have access to information relating to markets, economic opportunities, jobs, and weather to name just a few. When poor village farmers from Bangladesh can auction their crops on a craigslist-type service over the mobile phone, or government officials gain instantaneous information on contagious diseases via text message, the miracles of mobile connectivity move us from luxury to necessity. And we are only in the early stages of what the mobile electronic communications will mean for mankind. We are now "The Mobile Generation." Aspen Institute Roundtable on Information Technology. To explore the implications of these phenomena, the Aspen Institute Communications and Society Program convened 27 leaders from business, academia, government and the non-profit sector to engage in three days of dialogue on related topics. Some are experts in information and communications technologies, others are leaders in the broader society affected by these innovations. Together, they examined the profound changes ahead as a result of the convergence of wireless technologies and the Internet. In the following report of the Roundtable meeting held August 1-4, 2006, J. D. Lasica, author of Darknet and co-founder of Ourmedia.org, deftly sets up, contextualizes, and captures the dialogue on the impact of the new mobility on economic models for businesses and governments, social services, economic development, and personal identity

    Analysis of roles and position of mobile network operators in mobile payment infrastructure

    Get PDF
    A number of different mobile payment solutions have been presented the last decade. The phone subscription with its security mechanisms are used for user identification and payments. This is the case for SMS based payment and ticketing systems that are getting more and more popular. However, there are other ways to implement a Trusted Element (TE) , where a SIM card architecture is only one. It can be in the mobile phone, as a separate integrated circuit, as an optional customer deployed plug-in device (e.g., microSD) or be running as an application on a server existing entirely as software. In this paper we analyze what roles and responsibilities different actors have in different types of mobile payments solutions. The main focus is on the implications for the mobile operator business. It turns out that new types of intermediary actors in most cases play an important role. Sometimes mobile operators are not even involved. The emergence of new payment together with other non-SIM card based TE solutions opens up for many different market scenarios for mobile payment services. --

    History of communication in Malaysia (1940-2008)

    The Second World War was, in some ways, one of the lowest points in Malaysia's history. Japanese forces landed on the northeast border of Malaya on 8 December 194 1 and, in one month, succeeded in establishing their control of both Peninsula Malaya and Sabah and Sarawak. On 15 March 1942, Singapore surrendered. Singapore was renamed Shonan and became the centre of a regional administrative headquarters that incorporated the Straits Settlements, and the Federated Malay States and Sumatra. Much like the British who had installed residents in the Malay ruling houses fifty years earlier, the Japanese appointed local governors to each state. The only difference was that this time, it was the Sultans who were placed in the positions of advisors. The Unfederated Malay States, Perlis, Kedah, Kelantan and Terengganu found themselves back under the sovereignty of Thailand in 1942, when Thailand declared war on Britain and the USA. Most large scale economic activities grounded to a halt during the period of the War. The production of tin which was already falling before the War stopped almost completely. People turned their occupation away from the cultivation of commercial crops, concentrating instead on planting rice and vegetables to ensure they did not go hungry. [1

    An analysis of mobile internet service in Thailand: Implications for bridging digital divide

    Get PDF
    Mobile Internet is growing around the world without exception for developing countries like Thailand by passing the poor legacy wired infrastructure. This study attempts to provide guidance to a national regulatory agency (NRA) by addressing the following question: What are the key determining factors to explain the probability that individual consumer will use mobile Internet? The discrete choice model is employed to empirically examine whether the service and application attributes, socio-economic variables and service provider has systematic link with the decision of consumer. The data from a national survey in 2010 commissioned by the National Telecommunications Commission (NTC) of Thailand is used for the analysis. Based on the findings, fixed telephony, e-mail, age, area of living and mobile operator are recognized as the strongest determinants for mobile Internet adoption. The findings suggest that the mobile Internet becomes an alternative technology to bridge the digital divide since a group of people who have no fixed Internet connection at home they can connect the Internet via mobile Internet. As such, telecom regulator and policy makers need to consider the policies regarding to infrastructure investment frequency allocation, content and application development and competition in order to stimulate the growth of mobile Internet adoption and close the digital divide within country. --Mobile Internet,digital divide,developing country

    With its growing usage, mobile technology is greatly improving disaster relief and public safety efforts. Countries around the world face threats from natural disasters, climate change, civil unrest, terrorist attacks, and criminal activities, among others. Mobile devices, tablets, and smart phones enable emergency providers and the general public to manage these challenges and mitigate public safety concerns.In this paper, part of the Brookings Mobile Economy Project, we focus on how mobile technology provides an early warning system, aids in emergency coordination, and improves public communications. In particular, we review how mobile devices assist with public safety, disaster planning, and crisis response. We explain how these devices are instrumental in the design and functioning of integrated, multi-layered communications networks. We demonstrate how they have helped save lives and ameliorate human suffering throughout the world
