Investigation of factors affecting the diffusion of mobile telephone services: An empirical analysis for Vietnam

This paper analyzes the diffusion of mobile telecommunications services in Vietnam and examines how telecommunications regulation and potential substitute/complement services affect the growth of the number of mobile telephone subscribers. Using a logistic diffusion model, it is found that fixed telephone services are a complement while data services have a negative relation to mobile telephone services in Vietnam. As for regulation, the policy of introducing competition has been found to be the most effective in influencing the adoption of mobile services. Another important result is that the estimated potential market is roughly 76% of the total population. The findings suggest that suitable regulation that guarantees competition in the mobile telecommunications market in a developing country such as Vietnam is one of the most important factors for a positive diffusion process.     

Critical reflections on research approaches, accounting regulation and the regulation of accounting

The design and choice of research approaches, the nature of accounting regulation and the reactions to these regulations in organisations, involving, in effect, the regulation of accounting, are three themes of considerable importance in accounting research. They are the three themes that have dominated the research agenda of the author throughout his academic career. This paper explores the nature of these three key research themes developing some critical reflections on what has been discovered about each of these themes using the author's sole and joint research and publications as a vehicle for this analysis.     

通道费的避税效应与规制

收取通道费在我国已成为零售企业的一种盈利模式,而零售商向供应商滥收通道费引起我国当前工商矛盾尖锐化。本文分析了我国通道费的概念和构成,发现零售商收取通道费具有避税效应,这是我国通道费盛行的原因之一。由于通道费构成的复杂性,解决通道费问题不宜硬性取消或强制采取控制的规定,政府可以采用征收通道费税的办法予以规制。本文通过模型设计,得出调节通道费的控制变量,设计了针对通道费的征税机制,为政府规制零售商收取通道费行为提供了依据。     

Telecommunications in the land of the Thunder Dragon: recent developments in Bhutan

This paper charts the development of telecommunications in Bhutan. Since the introduction of telecommunications services in 1963 Bhutan has faced many challenges as it has sought to roll out a network that covers the whole population and country. A small population, a mountainous geography, a transitional economy and a unique approach to development—Gross National Happiness—present many challenges that need to be overcome if the telecommunications industry is to develop further. Added to this is the decision of Bhutan to join the outside world through membership of the ITU, APT and WTO that has added liberalisation and privatisation to the challenges faced by Bhutan. This paper identifies two broad policy options that Bhutan could adopt—network expansion nationally or investment concentration towards urban areas. The authors conclude that due to the limited resources available to Bhutan these policies are contradictory and will take the telecommunications industry in quite different directions if adopted.     

投资者利益保护与新兴市场证券发行管制

本文构建了一个模型,说明在一个非有效程度比较高的证券市场中,公司可以通过发行新股融资侵占外部公众投资者的利益。此时,证券发行的门坎管制和规模限制对保护投资者利益是必要和有效的;如果事后的投资者利益的法律保护等监管制度的有效性弱, 证券发行管制就更有必要,以此来限制经营能力较差的公司为NPV<0的项目融资。对融资和投资分离的研究还表明,限制上市公司融资规模可以减少管理层基于自我利益的过度融资和低效投资。随着投资者保护的法律制度完善和执行有效,信息披露规范,加上机构投资者力量壮大,市场评价能力增强,可以放松证券发行事前的门坎限制和融资规模限制,逐步实现证券发行市场化。

Which firms engage small, foreign, or state banks? And who goes Islamic? Evidence from Turkey

We study a representative dataset from Turkey that identifies firm–bank connections. Banks in Turkey differ not only in size and nationality, but also in ownership and orientation (non-Islamic versus Islamic)—resulting in at least six distinct bank types. We estimate a multinomial logit of the choice by the firm of bank type. We document a strong correspondence between bank type and firm characteristics that is not always the same as has been documented so far for US datasets. For example, small firms engage large rather than small banks. Young, large, multiple-bank, and industry-diversified firms, that are located in or close to Istanbul, team up with foreign banks. Islamic banks mainly deal with young, multiple-bank, industry-focused and transparent firms.
