Potential user factors driving adoption of IPTV. What are customers expecting from IPTV?

Internet Protocol Television (IPTV), the convergence services of television and Internet, is being rapidly developed around the world. The advent of digital technologies has changed the convergence market dramatically with the wide diffusion of the convergent services. Using the Technology Acceptance Model as a conceptual framework and method of logistic regression, this research analyzes the demand for IPTV by drawing data from 452 consumers. Individuals' responses to questions about whether they accept IPTV are collected and combined with observations of their socio-economic status and intrinsic/extrinsic factors modified from the Technology Acceptance Model. Results of logistic regression show two variables (intrinsic and extrinsic factors) that seem to explain what influences consumer behavior towards adopting IPTV. Overall, the logistic regression model explains over 50% of the variance in the IPTV adoption. The variances shed light on the multi-open platform environment that IPTV will forge.

An instrumental variable approach for panel unit root tests under cross-sectional dependence

For dynamic panel models with cross-sectional dependence, several unit root tests are constructed using a Huber-type instrument, whose null asymptotics are standard Gaussian and do not depend on nuisance parameters. A Monte-Carlo simulation shows that the proposed tests have better sizes and comparable powers relative to other two existing tests developed for cross-sectionally dependent dynamic panel models.     

The rationality and efficacy of decisions under uncertainty and the value of an experiment

Summary A decision maker faces a known prior distribution over payoff relevant states. We compare the expected utility of this individual under two scenarios. In the first, the decision maker makes a choice without further information. In the second, the decision maker has access to an experiment before choosing an action. However, the decision maker does not know the true joint distribution over states and messages. The value of the experiment as measured by the difference in the two utility levels can be negative as well as positive. We give a condition which is necessary and sufficient for the experiment to be valuable in our sense, for any decision problem.An earlier version of this paper was circulated under the title Noisy Bayes Updating and the Value of Information. We have gained from the comments of Stephen Coate, John Geanakoplos, Larry Samuelson, Timothy Van Zandt and seminar participants at Harvard Business School, Princeton, Boston University, the international conference on game theory at Stony Brook 1992 and the Winter meeting of the Econometric Society at Anaheim 1993.

Project Management Characteristics and New Product Survival

We develop a conceptual model of new product development (NPD) based on seminal and review articles in order to answer the question, “What project management characteristics will foster the development of new products that are more likely to survive in the marketplace?” Our model adopts Ruekert and Walker's theoretical framework of situational dimensions, structural/process dimensions, and outcome dimensions as an underlying structure. We conceptualize their situational dimensions more narrowly as project management dimensions, allowing us to examine more specifically how project management practices affect the NPD process. In our model, project management dimensions include project manager style, project manager skills, and senior management support. Structural/process dimensions include cross‐functional integration and planning proficiency. Outcome dimensions include process proficiency and new product survival. Our empirical analysis finds support for 20 hypotheses, a reversal of one hypothesis, and nonsignificant results for one hypothesis. These results show that projects are best led by managers with strong technical, marketing, and management skills, using a participative style and enjoying early and continuous support from senior management. These project management dimensions promote cross‐functional integration and planning, which are important to process proficiency and new product survival. Our study suggests two broad conclusions. First, it confirms the links in the extant literature between situational (project management) dimensions, structural/process dimensions, and outcome dimensions in NPD. Second, firms can improve cross‐functional integration and planning through various project management practices. Generally, we find that firms interested in improving both proficiency in their development process and the survival rate of new products should take steps to promote cross‐functional integration and to improve their planning processes. While the linkage between cross‐functional integration and NPD outcomes is well established in the literature, the impact of the planning process on NPD outcomes is a research area ripe with opportunity. Our study highlights three aspects of planning that contribute to NPD outcomes. Plans should be detailed, team members should participate actively in the planning process, and teams should be given flexibility and autonomy to respond to unanticipated issues as they appear.

The Effects of Oil Price on the Korean Economy: A Global VAR Approach

This article empirically explores the effects of oil price on the Korean economy using a Global VAR model. First, we evaluate the average connectedness of oil price with the Korean domestic variables over the precrisis period. We then investigate the time-varying contribution of oil price to the Korean financial and real sectors during and after the global financial crisis through recursive estimation. It is found that the contribution of oil price becomes very large in the case of real exports, equity prices, and real output, but plays a much less prevalent role in the remaining cases. In the meantime, the time-varying contribution of oil price to the Korean economy has not changed during and after the global financial crisis. Interestingly, we find that the Korean economy is affected mostly by overseas financial conditions in the short-term but it becomes more susceptible to oil price fluctuations in the long run, suggesting that Korea’s reliance on energy imports leaves the economy exposed to volatility in energy prices.     

Reconstructing Urban Politics with a Bourdieusian Framework: The Case of Local Low‐Income Housing Policy

This research aimed to reconstruct a local urban politics and develop a meso–micro‐level model of urban politics through a case study, drawing on a Bourdieusian relational framework. To this end, it investigated the case of local low‐income housing policy — inclusionary zoning — in Madison, Wisconsin, USA. It historicized the path of the local low‐income policy issue through document analysis and qualitative media content analysis. Through multiple analyses, the study revealed that urban politics consists of complex interlinkages among stakeholders with shared values or interests from different social domains, created in order to dominate the policy issue. The study further investigated, on the basis of Bourdieu's concepts of capital and habitus, what elicited different political strategies from key community leaders.     

Impacts of household loan regulation on financial stability: evidence from Korea

The paper examines whether banking regulations and monetary policy contributed to controlling the fragility of household debt in Korea. The results show that housing loan regulations such as debt to income regulation contributed to a lower household debt delinquency ratio. Lowering the target interest rate provided additional stabilisation of the delinquency ratio. It is recommended that the government adopt an appropriate mix of regulation and monetary policy to control household financial fragility. The financial supervisory services need to be involved in managing debt to income regulation and minimising financial instability and financial market distortions. Further, the monetary authority has to adopt a more effective position in controlling the real lending interest rate and the delinquency ratio of household loans. Such a policy mix will improve effectiveness in controlling financial fragility, especially at a time of financial crisis.
