Internet telephony: Costs,pricing, and policy

This article analyzes Internet Service Provider costs and regulatory and policy issues raised by Internet telephony. Transport and non-technical items such as customer service, sales and marketing, represent a substantial portion of an ISP’s costs with Internet telephony. Pricing models and yield management techniques supporting Internet voice services might be employed for other Internet differentiated services as well. An integrated regulatory framework will be required, because of convergence, to formulate policies for multimedia services. We conclude that governments should develop appropriate policies without introducing economic and technical distortions into the nascent Internet telephony market.     

Diffusion of mobile telephony: An empirical study in Taiwan

Mobile telephony penetration is a major indicator of mobile telephony diffusion. Taiwan had a mobile telephony penetration of 108% in 2002, ranking first in the world. This study analyzes this accelerated diffusion in terms of growth model and determinants of the diffusion rate. To eliminate the inherent uncertainty associated with choosing the optimal growth model, this study compares the performance of three conventional models, namely Gompertz, Logistic and Bass, to identify the most appropriate model, and to distinguish the forces driving the diffusion rate. Empirical results indicate that the most appropriate model is the Logistic model. Network externalities, which this study shows to be the same as the imitation effect in the Bass model, explain the superiority of the Logistic model. Moreover, market competition, which markedly reduces service prices, is identified as a primary driver of the diffusion rate of mobile telephony in Taiwan. Economic conditions, technological innovation and number of operators are insignificant factors. Finally, mobile telephony is a substitute for fixed-line telephony in Taiwan.     

Collaborative approaches to public sector innovation: A scoping study

In the last 15 years, European countries have invested considerable resources to provide e-government services. Despite of its increasing availability, its level of adoption has not been satisfying. On the other hand, over the last years, coinciding with the web 2.0 trend, the e-government services co-produced by citizens start to appear, often without the support, acknowledgement and even awareness of the government. This trend stems from a well-established tradition of offline co- production of public services, i.e. services provided by the voluntary sector, but brought to an unprecedented scale thanks to the advent of web 2.0. Still, the concept remains not well-defined and its impact is not yet well studied. The paper explores on a limited sets of cases what does it mean to collaboratively deliver online public services; what are the success factors based on the cases under study and what are the incentives for service providers (other than public administration), citizens as users and public administration. The authors propose an ostensive definition of the collaborative delivery of public services: collaborative public services are created and run by government, civil society or by private sector building on the re-use of government data or citizens data. Those services are focused on public goods delivery (e.g. health, education, public transport) and are meant to change the traditional government services by engaging in an open dialogue with public administration about the best way to deliver those services. The analysis of six case studies of innovative collaborative online public services suggests that the online collaborative public service delivery increases its quality with the users׳ growth contrary to the traditional offline service delivery. The study results indicate that the current developers interest lies in delivering complementary services to the government run services rather than substitutive services. The authors propose also the initial list of success factors, enabling conditions, and benefits for all main stakeholders (users, innovators and public administration).     

A comparative analysis of new product development by Italian and Japanese manufacturing companies: A case study

Based on survey data from Italian and Japanese companies, six measurement scales are developed for practices, process, strategic guide, and capabilities for new product development as potential determinants of its financial performance, that is, attainment of profit goals and revenue goals. By employing a regression model with a country dummy variable, the differential determinants of financial goals attainment between Italian and Japanese samples are estimated. A significant difference can be found in the impact of new product development capabilities on profit goals attainment only. Then, we evaluate the level of improvement in explanatory power by dividing the pooled sample into two and enabling regression coefficients to take different values, and find no evidences of the significant improvement. Technology and marketing capabilities concerning new product development are demonstrated to be overwhelmingly important to financial performance.     

Convergence and diversification in cable industry: An empirical analysis of the deployment pattern of cable telephony in US local telecommunications markets

The primary purpose of this study is to examine the deployment pattern of cable telephony in the US local telecommunications market. A model is established stressing that the size of local markets and the specific cost advantages of local cable systems are associated with the deployment of cable telephony by cable operators.     

Cost allocation and regulatory pricing in telecommunications : A UK case study

This article describes the application of alternative cost allocation methodologies to the Hull telephone system, which provides service to a small area of the UK independently of British Telecom. The article first discusses alternative uses of and methods for allocating costs among access, local usage and trunk usage. It then implements the fully distributed cost approach, using accountancy data provided by the company. In addition, several illustrative calculations are shown which cost individual services on a stand-alone basis using different technologies. The results broadly suggest that, on a full distributed cost basis, access costs exceed existing average tariff levels. The article concludes with some illustrative calculations showing the rebalancing of access and usage charges which would generate the same revenue but bring them more in line with costs.     

The role of the Internet in new product performance: A conceptual investigation

Past research has extensively investigated the role of the Internet in enhancing the effectiveness and efficiency of the new product development (NPD) process. Although the process implications of the use of the Internet in NPD have received considerable attention in the literature, very little is written about the Internet's performance implications in NPD. Recognizing the importance of new product success and the growing trends in the use of the Internet in NPD, this paper investigates the role of the Internet in new product performance. Building on previous studies, this article develops theoretical explanations for the impacts of the use of the Internet in NPD on new product success and presents testable research propositions. It also outlines relevant conditions that might moderate the strength of the impacts.     

Singapore-based subsidiaries of US multinationals and singaporean firms: A comparative management study

The objective of this exploratory study is to compare and contrast various aspects of US management with Singapore management. One hundred and four top managers, 99 middle managers and 780 operating employees from 20 manufacturing companies participated in the survey. The chief executive of each company was contacted by mail before the survey was begun.Hypotheses concerning the management philosophies, management practices and management effectiveness were tested for differences between US subsidiaries and Singaporean firms.The results of the research indicate significant statistical differences for the two groups of companies with respect to the management variables. Explanations regarding these differences are presented.A paper comprising a substantial portion of this article was presented by the author at the43rd National Academy of Management Conference held in Dallas, Texas between August 14 and 17, 1983.The author is grateful to Dr Bruce W. Stening, of the Department of Management at the University of Western Australia for his perceptive guidance during the study. The author is with the Department of Management, University of Western Australia.     

Control-trust interplays and the influence paradox: A comparative study of MNC-subsidiary relationships

This study focuses on the interplay and possible coexistence of control and trust when influencing others and when being influenced. The paper presents an analysis of change processes whereby an actor becomes ‘a trusted influenced other’. This occurs due to the controls that take place, rather than despite of these. It is suggested that intended purpose and perceived legitimacy need to be considered, as well as the type and level of control. Moreover, imbalanced interactions whereby the other actor is prevented from becoming a source of influence may negatively impact the overall development and exploitation of knowledge. A second dimension in the studied relationships is when the other becomes ‘a trusted source of influence’, not only a ‘trusted influenced other’.     

Regulatory factors influencing Internet access in Australia and China: a comparative analysis

Internet access is determined by a combination of a widely available telecommunication infrastructure and affordability of Internet services, which are closely related to government policies (IT Group. (1999). Like other countries, both Australia and China have considered the Internet a powerful tool for national development economically and socially. As Internet growth becomes more and more significant, it becomes important to address the extent to which the underlying communication policies influence current growth rates.This paper provides a comparative review of policy approaches to regulating the Internet in both China and Australia. This study aims to identify the regulatory factors affecting Internet access in terms of availability and affordability, especially those factors which encourage the creation of a policy and regulatory environment favourable to the development of Internet infrastructure and access.This paper examines the linkages between regulatory regimes, market environments and Internet access in both China and Australia. The preliminary result suggests that government policies governing the telecommunications service market and promoting information infrastructure have a significant impact on the affordability and availability of Internet access. The most significant factor is the level of competition permitted in the telecommunication sector. It has become clear that further regulatory initiatives such as deregulatory mechanisms and interconnection regimes are needed to establish a more competitive environment for Internet access in both countries, and more particularly in China.     

Exploring the ethical behavior of managers: A comparative study of four countries

Donaldson and Dunfee's (1994) social contracts theory of economic ethics was subjected to empirical scrutiny to determine whether it can explain differences in behavior between cultures. Data collected utilizing a series of vignettes developed by Fritzsche and Becker (1984) were examined for differences in indicated ethical behavior among American, Japanese, Korean and Taiwanese managers. Rationale for the behavior was classified according to hyper and community norms which were supported or violated. The results suggest that the three East Asian countries do not neatly cluster together in relation to the U.S. in terms of their patterns of ethical behavior. Nonetheless, when we examined the specific rationale for the decisions provided by the managers, the effects of Asian cultural characteristics became more notable. We also found that the social contracts theory provided a much needed bridge between ethical universalists and relativists. The specific reasons underlying their decisions are discussed in the light of cultural and social differences.This research project was partially supported by a research grant from the School of Business and Management, The Hong Kong University of Science and Technology.     

Purchasing's role in computer buying: A comparative study

The sale of Electronic Data Processing (EDP) equipment represents a large and growing market both in number of dollars and products. This article analyzes the purchaser's perceived role in the EDP acquisition process from both public and private sector perspectives. Major public and private sector purchasing differences are discussed in terms of their implications for improving EDP marketing success. Differences discussed include: purchaser influence in the EDP decision process, necessity of seller-buyer interface, method of purchase, and purchasing's organization structure for buying EDP equipment.     

Quality of working life in the automobile industry: A Canada-UK comparative study

The paper examines the impact of lean production on indicators of the quality of life at work in the automotive industry and finds that it varies across companies and to a lesser extent between countries. The paper explains this by arguing that lean production seeks to impose new employment standards. This is a contested process where management's capacity to shift to new standards and labour's ability to protect its interests vary across workplaces.     

Espoused drum-buffer-rope flow control in serial lines: A comparative study of simulation models

This paper documents an investigation of drum-buffer-rope (DBR) scheduling and flow control methodology in single-product serial production lines. In particular, DBR flow control is reviewed and the importance of correctly representing this type of flow control mechanism in serial lines is discussed. Departures from valid DBR conceptual and simulation modeling are illustrated. It is shown that the model of a previously published paper is a push system not a DBR system, and that related conclusions regarding protective capacity and constraint location are unsupported. Correct modeling of DBR flow control is shown using discrete simulation experiments that compare the DBR model and a similar push model. Suggestions for additional research are offered.     

Communications and telecommunications: Integrated approaches to communications planning

The author argues for an integrated approach to the formulation of communication policies. He suggests that the term ‘communication planning’ signals changes in attitudes to planning in general, breaking through the boundaries of technical or quantitative exclusivity into a broader, more interdisciplinary approach. After describing the main characteristics of the integrated approach, he examines the Unesco Afghanistan survey as an example of recent work on the methodology of overall communication system planning. The author then discusses the issue of technology transfer in the context of communications, and concludes with an analysis of the trend towards the international coordination of planning approaches.     

Contestability and creative destruction: Two approaches to monopoly

The theory of contestability ’attempts to base a model of economic efficiency on oligopolistic markets, thereby justifying adoption of laissez-faire policies in the absence of atomistic competition. The analysis is similar to Schumpeter’s condemnation of government intervention in the theory of creative destruction: both theories claim that superior economic performance is associated with concentrated rather than competitive market structures. Yet in many respects the contestability analysis is less convincing than Schumpeter’s. Whereas Schumpeter admitted the existence of short rum profits and restrictive strategies, arguing that these inefficiencies, are outweighed in the long run, the theory of contestable markets is based on short run efficiency and cannot accommodate evidence of excess profits nor many of the existing models of oligopolistic strategies, including collusion and predatory pricing. Furthermore, the theory lacks a logical explanation of investment, by entrants and convincing empirical support for its claim that concentrated markets maximize consumer welfare.     

Upward and downward influence tactics in managerial networks: A comparative study of Hong Kong Chinese and Americans

This paper reports an empirical investigation of individual preferences in the use of managerial influence tactics by Hong Kong Chinese and Americans. Subjects in a cross-cultural scenario study were asked to evaluate alternative upward and downward influence tactics in terms of their preferred usage. The findings indicate a main effect for culture and for direction of influence attempt. In addition, direction of influence attempt interacts with subject gender and culture on a tactic-by-tactic basis to reveal differences in influence preferences. Implications of the findings and directions for future studies are discussed.This research was supported by The Chinese University of Hong Kong. The special assistance of Mimi Kam and Ricky Lam in back-translation of the research instruments is appreciated, as are the contributions of Joseph Raelin of Boston College and Harold Welsch of Depaul University in data collection.     

The buying network in international project business: A comparative case study of development projects

While previous research has found project buying to be distinct from other buying situations, in that it typically involves a multi-organizational network, to date there has been very little empirical research on this phenomenon. Our aim in this paper is therefore to investigate the structure and decision-making processes of the project buying network during the project cycle and its interactions with project sellers. We first develop a preliminary conceptual framework for analyzing the project buying network, which is then applied to a comparative case study of three development projects. The findings from the case study allow us to propose a revised conceptual framework for analyzing the dynamics of the project buying network during the project cycle, as well as interaction with sellers. Our findings also contribute an understanding of development projects, in particular the role of financiers.     

The cultural milieu of management: A comparative study of the role of management in ASEAN

The role of a business school and form of management education in any country must depend on the specific role of management in the economy. This, in turn, depends on the milieu or business ambience in which management must operate. A set of types of milieu can be distinguished for ASEAN countries which form a sequence approximately correlated with the process of modernisation. The different tasks and required traits for management in the various milieus are discussed and some implications for management schools and education noted.
