Profiling mobile TV adopters in college student populations of Korea

By profiling demographic characteristics, perceived general adoption attributes, perceived value-based adoption attributes, motivational needs, mass media use, and content interest, this exploratory study examines the nature of four categories of mobile TV adopters — current, potential, continuous non-, and discontinuous user groups. Despite the limited sample size (N = 214), there are some meaningful findings. First of all, the non-adoption rate of mobile TV of the continuous non-, and discontinuous user groups is higher than the adoption rate of the current and potential user groups. Less than half of the respondents (N = 34) who had used TV on a mobile device were unwilling to use it again in the next twelve months, and almost half of those (N = 102) did not have the intention of using it within the coming year. The results suggest that the discontinuous group seems to have been dissatisfied with the actual mobile TV use when compared with their expectations and evaluations, while the potential user group is more likely to have high expectations and positive evaluations before the adoption and use of mobile TV. All user groups were unwilling to pay the fee, despite the current and potential user groups perceiving the exceptional values. No differences were found in the personality trait of innovativeness and mass media use behaviors among the four groups.     

Inside the learning dynamism inducing the resonance between innovation and high-demand consumption: A case of Japan's high-functional mobile phones

Confronting the simultaneous global economic stagnation that has resulted in diminishing consumption, a new driver which can instill in customers an exciting story with their own initiative and thrills them with gratification of consumption is essential. Japan's mobile phone driven innovation may provide a constructive suggestion to this requirement.On the basis of an empirical analysis focusing on the learning dynamism for innovative products in Japan's digital industry, this paper demonstrates the foregoing hypothetical anticipation. Based on measurement of dynamic learning coefficients for seven leading innovative products centered on mobile phones, the Granger causal test, Chow forecast test and wavelet analysis were conducted, and the significant role of mobile phones in leveraging broad dissemination, learning and absorption of core technologies essential to the advancement of digital industry was identified. Furthermore, significant role of demanding customers in inducing resonance between mobile phones learning and that of innovative products was demonstrated.

A Student Learning Inventory for Economics Based on the Students' Experience of Learning: A Preliminary Study

The authors present the initial development of a student learning inventory (SLI) that is specific to economics. This approach, which is based on the student experience of learning (SEL) literature, emphasizes aspects of prior knowledge in the learning history of entering first-year students. Preliminary insights from a first SLI suggest that on entry to university, students show considerable variation in their perceptions of what economics is and what economists do. From the SEL perspective, such variation affects student learning. It is argued that continued development of an economic-specific SLI may result in a better understanding of students' learning engagement with economics and ultimately assist instructors in better understanding student learning difficulties and increase student success in first-year economics.     

Dynamic technological learning trends in Turkish manufacturing industries

Efficient development of industries requires a broad range of technological capabilities which can be acquired only by a long process of learning. Continuous measuring and monitoring of the ever-changing technological learning would be useful for building technological capability and managing technological policies. Nevertheless, research on how to measure the technological learning over time at macro levels remains largely untouched. In this paper, by adding the experience curve into the multifactor productivity part of Neoclassical production function, we will develop a model which will allow one to estimate the technological learning levels over long periods. This model would allow a user to both estimate the past learning experiences and forecast its future path on a time varying basis. The model has been used and tested in the estimation of the annual technological learning values for 28 Turkish manufacturing industries from 1981 to 2000.     

The future of the mobile phone business

One of the fastest growing technologies of our times is that of mobile phones. In this article we use the assumption that the diffusion of mobile technology, as measured by the number of active mobile accounts, follows the well known S-curve of natural growth in competition systems. The accuracy of the logistic fit is tested against actual data for the whole world, Europe, China and the GSM system. Using the produced models predictions concerning the future of mobile business are deliberated.According to these models active mobile accounts around the globe are expected to grow from 1.7 billion in 2004 to approximately 2 billion in 2008, reaching a peak penetration of 29.2%. Growth barriers, apart from the age of the potential user, are also low income and extreme poverty. Europe, early adopter of mobile technology and leader in active mobile accounts against all other regions in the world, has apparently reached a peak with almost every European, apart from the very young or very old, using a mobile phone. The mobile market in China is anticipated to exceed 500 million active accounts and may increase even further depending on the economic and social reform that is currently under way in that part of the world. GSM will most likely remain the leading mobile technology in the future as it is today.The growth process for the world, Europe, and the GSM system is almost completed and during this stage instabilities may occur before the potential emergence of a new wave of growth.

Messy conversations and the willingness to be disturbed

We all long for a sense of community in our professional lives where we can bring our spirit, passion, and whole selves to work. When we work in environments of tribal warfare and clans carrying out subversive activities, we will choose to leave our souls at home to protect them from the toxicity of the work environment. For anyone who has been cared for by nurses who have left their soul at home, you have experienced the outcome of negative environments that cannot have effective conversations. Recently a nurse told about her experience of realizing one day that she had the right to be happy at work so that she could more effectively take care of her 5-year-old daughter when she returned home. When she saw this as a right, she made a decision to leave her organization and look for a place that valued conversations and harmony rather than aggression and lack of trust. The only way to improve the world is through relationships, and conversations are the prelude to creating that change. Having the courage to reach out and start the dialogue knowing full well that it might be very messy is the only way to end the fragmentation and loss of community we experience in our organizations. Wheatley (2002) describes the experience of "...sacred as a feeling that I belong here" (p. 133). In the process of conversations, we can explore and appreciate our differences but also feel more connected and one with each other as a result of having the courage to converse. When we see each other as equals, we also free ourselves to open up to new learning and relationships which can lead to excellence in clinical outcomes. It's all about the courage of conversations.$     

Economic determinants of global mobile telephony growth

This study examines the substitution effect between fixed-line and mobile telephony while controlling for the consumption externality associated with telephone networks. A dynamic demand model is estimated using a global telecommunications panel dataset comprised of 56 countries from 1995–2000. Estimation results show the presence of a substantial substitution effect. Additionally income and own-price elasticities are reported. Analysis of impulse responses for price, income and network size indicate substantial mobile telephone growth is yet to be realised. However, price ceilings imposed in the fixed-line network can retard the growth of the mobile network.     

Comparative Learning Dynamics*

We study economic environments in which agents make choices on the basis of relative performance criteria and call the associated class of dynamic adjustment rules comparative dynamics. We distinguish two classes of learning behavior: learning from the population experience (imitative dynamics) and learning only from one's own experience (introspective dynamics). Paradoxically, for a broad class of models, comparing stochastically stable states across dynamics, agent payoffs are lower for imitative than introspective dynamics—mimicking best practice in the population is counterproductive.     

Taxation of firms with unknown mobility

We analyze optimal business tax policy when some firms are able to escape taxation by moving abroad. In contrast to the existing literature, we assume that the true number of mobile firms is ex ante unknown. While the government may learn from the firms' location responses to past tax rate changes, firms may anticipate this and adjust their choices accordingly. We find that incomplete information on mobility substantially affects the properties and the implications of equilibrium policy choices. First, the government may find it optimal to set a tax rate that triggers partial firm migration but full revelation of the true number of mobile firms. Second, we show that, if the firms' outside option is attractive (i.e., relocation cost and foreign tax rates are low), expected tax rates and expected firm migration are higher if the degree of mobility is unknown. Third, there is a positive value of learning, i.e., commitment on future tax rates cannot increase the government's expected revenue. However, if the government can commit to a rule‐based learning mechanism, i.e., credibly tie its future tax policy to present policy outcomes, it may obtain a Pareto improvement.

Gross world product and consumption in a global warming model with endogenous technological change

This paper analyzes the macro-economic costs and effects on consumption and energy demand of limiting the global average atmospheric temperature increase to 2 °C. We use a macro-economic model in which there are two competing energy technologies (carbon and non-carbon, respectively), technological change is represented endogenously, and energy is aggregated through a CES function implying positive demand for the relatively expensive non-carbon technology. Technological change is represented through a learning curve describing decreasing energy production costs as a function of cumulative experience. We find that energy savings constitutes an important mechanism for decreasing abatement costs in the short- and medium-term, while the acquisition of additional learning experience substantially decreases abatement costs in the longer-term.     

Upstream regulation in mature network industry: evidence from Nordic mobile telecommunications markets

This article investigates the effects of upstream regulation that aims to create niches and attract new type of entrants on the competitive environment of downstream markets. Using unique cross-country data of Nordic mobile telecommunications markets, we show that upstream regulation leads to (i) increases in both number and aggregate market share of service-based providers in the downstream market, (ii) an increase in the number of service-based providers, thus increasing their aggregate market share, but no opposite direction of results and (iii) a lower retail price level, proxied by average revenue per user. Our findings imply that upstream regulation may be able to achieve better outcomes when the policy objectives are to revitalize mature network industries and to enhance consumer welfare.

Do Gatt Rules Help Governments Make Domestic Commitments?

We investigate empirically whether GATT rules may have helped the US government make trade policy commitments to its private sector. We study choices under two distinct environments. One environment is the determination of sectoral exclusions in the Tokyo Round of GATT negotiations. The other is the determination of tariff responses under GATT's escape clause. In each environment the US government was faced with a similar decision, but only in the former environment did GATT rules serve as a potential commitment device. Comparing decisions made across these two environments, we find evidence that GATT rules did help the US government make domestic trade policy commitments that it could not have made in the absence of these rules.     

Temptation and social security in a dynastic framework

We investigate welfare and aggregate implications of a pay-as-you-go (PAYG) social security system in a dynastic framework in which individuals have self-control problems. The presence of self-control problems induces individuals to save less because of their urge for temptation towards current consumption. Individuals' efforts to balance between the short-term urge for temptation and the long-term commitment for consumption smoothing result in self-control costs. In this environment PAYG social security works as a self-control cost reducing device. In contrast, the presence of altruism induces individuals to save more. This in turn mitigates the adverse effects of self-control problems and PAYG social security on savings but magnifies the self-control costs. We find that in our environment the adverse welfare effects of a PAYG system are further mitigated relative to the environments that incorporate altruism and self control issues separately. However, the level of mitigation is quite modest.     

体验消费与"享用"体验

体验消费是指在一定的环境氛围中,消费者对物品和服务的"享用"关系.体验消费可分为积极和消极的体验消费形式,其价值可区分为自我实现(1)和自我实现(2).体验消费凸显享用性,以其注重消费的内在化、精神化、生态化、创新化的特性而成为人们生活殷实的一个象征,并使体验者不断提升到更高的消费境界.在全面建设小康社会大背景下,企业提供能诱发和唤醒人们体验的产品和服务,等于为消费者提供了享用价值,也为我国经济增长提供了新的契机.
