PRICING REGULATIONS AND NETWORK TECHNOLOGY INVESTMENTS: A RETROSPECTIVE EVALUATION

This article evaluates the impact of the introduction of incentive regulation on technology deployment, as evaluated using two technology deployment metrics, among the population of local exchange carriers in the USA between 1988 and 2001. The regulatory schemes are disaggregated into five categories, permitting examination of heterogeneity among regulatory schemes. The results show that the rate of return method and the other intermediate incentive schemes implemented have had a negative impact on technology deployment. Conversely, the introduction of pure price caps schemes had a positive and significant impact on firms’ technology deployment. These results highlight the importance of appropriate incentive compatible mechanism design in motivating firms to adopt the new and important technologies that have been developed.     

The role of HR practices in developing employee resilience: a case study from the Pakistani telecommunications sector

Abstract

There has been increasing interest in understanding the factors that contribute to the development of employee resilience. Despite such interest, there is a dearth of research examining the contributory role played by HR practices in enhancing employee resilience. Looking at the context of Pakistan’s telecommunications sector and deploying a qualitative methodology, this paper examines the impact of HR practices on employee resilience. The findings indicate that four key areas of HR practices – job design, information sharing and flow within an organisation, employee benefits (monetary as well as non-monetary), and employee development opportunities – enable the development of employee resilience. Consequently, the effective implementation of HR practices in these areas has been the key factor for the development of employee resilience.     

Modelling and forecasting national introduction times for successive generations of mobile telephony

An accurate prediction of the timing of a country's introduction of a new generation of mobile telephony benefits numerous agents including suppliers of network and consumer equipment, regulators, and network planners. We consider the estimation and prediction of the time interval between the international introduction of a generation of mobile telephony and its introduction into a specific country when a decision maker judges the introduction of a newer technology a worthwhile investment. Using literature-based socio-economic and geographical variables, we examine how well variation in international introduction times of four generations of mobile telephony in 172 countries can be explained and forecast. We model and forecast introduction times at two levels of granularity: we use Cox's proportional hazards model for the introduction time; we partition countries into introduction time-based segments and model segment membership using multinomial logistic regression. Our modelling of each generation considers three subsets of explanatory variables: All variables, socio-economic Covariates only, Regional dummies only. Over successive generations, the Covariates only models reveal the changing relevance of each socio-economic covariate. Model-based forecasting of the introduction time of the next generation is performed under three hypotheses making different uses of the information available at the time the relevant generation is launched internationally. However, changing socio-economic environments coupled with changing models impair forecasting accuracy, the lower accuracy of modelled introduction times is concentrated in 20% of countries. We speculate about the nature of the unobserved factors affecting these countries' decision processes.     

Productivity Growth And Market Structure In Telecommunications

This study examines sources of telecommunications sector productivity growth. Total factor productivity (TFP) growth is calculated using the Malmquist productivity index for a sample of 74 countries for the period 1991 through 1995. An econometric model is estimated which relates TFP growth to output growth, network digitisation, telecommunications development, output-mix, the business cycle and market structure. Model estimates suggest that higher digitisation rates dampen TFP growth in the short run, and cross-subsidisation of services creates inefficiency. However, developing countries can increase TFP growth through catch up, and increased privatisation and competition are conducive to productivity growth.     

Compatibility Standards And Industry Competition: Two Case Studies

Case histories of two data communication interfaces provide evidence of complex strategic behavior in the setting of voluntary compatibility standards. These cases show how subtle differences in the design of standards development organizations affect incentives to cooperate, giving rise to systematic venue preferences. Dominant firms prefer more bureaucratic procedures offering greater protection for the status quo. The two interfaces, FDDI (under development in X3) and DQDB (under development in the IEEE) shed light on competition between the computer and telecommunications industries and the evolution of our communications infrastructure. They demonstrate the importance of standards for intra- and inter-industry competition.     

我国电信基础业务FDI壁垒及行业影响

本文的目的是分析加入世贸组织以来我国电信业基础业务开放的情况,并测量电信基础业务市场FDI壁垒及其对行业发展的影响。非政策性壁垒确定主要基于2010年对电信业中外资服务商的第一手调研资料,利用Warren壁垒评分标准和层次分析方法测算综合壁垒指数。研究结果表明,加入世贸组织以来我国基础电信开放的政策性环境有了明显改善,同时非政策性壁垒的影响开始显现,成为客观评价行业开放度的重要因素。研究还表明,通过扩大开放、提高利用外资水平来进一步促进行业发展仍有较大的空间。     

Restructuring in Telecommunications and its Market Impacts: An Event-Study Analysis

This study presents an assessment of the changes in the telecommunications industry and their impact on market returns. Events were identified from a sample of global telecom companies and assessed in terms of their favorable or unfavorable impacts. Based on event-study analysis with generalized autoregressive conditionally heteroskedastic specification, the impact was tested after incorporating dummy variables of different lengths. The results show interesting patterns in how the market views restructuring in the business model of telecom companies, organizational structure, alliances and mergers, and technological platform changes. Countries differ in how they view telecoms restructuring and what changes are considered beneficial by investors.

State Ownership, Privatization and Performance in Singapore: An Exploratory Study from a Strategic Management Perspective

This paper considers the ownership debate with regard to state-owned enterprises (SOEs) performance, that is, whether superior performance of SOEs can be achieved under state ownership. While the traditional belief has been, supported by empirical work, that private ownership is generally associated with superior performance, the experience of Singapore is a clear example to the contrary. We outline global privatization trends and discuss the impact of privatization programs. We then discuss Singapore Telecom as a case where state ownership combined with several contextual and firm-related factors, especially firm strategy, has led to sustained world-class performance. We develop a theoretical framework for this analysis based on the strategic management field. We lastly outline some theoretical and practical implications of the analysis.
