Political pressures and the credibility of regulation: can profit sharing mitigate regulatory risk?

When price-cap rules determine the structure of prices for a long period, they suffer a credibility problem and introduce an element of risk especially if a firm’s profits are “too large”. Profit sharing may be seen as a device to pre-determine price adjustments and thus to decrease regulatory risk. We analyse the effects of profit sharing on the incentives to invest, using a real option approach. Absent credibility issues, a well designed profit sharing system may be neutral relative to a pure price cap. With regulatory risk, profit sharing is preferable to a pure price-cap one, if it intervenes for high enough profit levels.

Effects of employees' perceived dependability on success of enterprise applications in e-business

Electronic business (e-business) plays a major role in modern economic networks due to its shorter cycle time and faster information transactions. Building enterprise applications that can coordinate activities, decisions, and knowledge across many functions is a good solution for e-business. Hence, how to implement enterprise applications successfully has become an increasingly important management issue. Although success of information systems (IS) has received fairly extensive attention from prior research, issues regarding whether functions and service delivered by systems can be justifiably relied on by users are seriously ignored, especially complex systems like enterprise applications. Thus, this paper attempts to extend this kind of concept, perceived dependability, into DeLone and McLean's IS success model to explore how it influences success of enterprise applications. Results from a survey of 170 respondents taken from six internationalized e-businesses in Taiwan strongly support that perceived dependability is indeed an important factor for success of enterprise applications. Additionally, over and beyond the effects of dependability on success of enterprise applications, it can help practitioners and managers get deep insights into how to implement e-business successfully.     

Technical efficiency and use of information and communication technology in Spanish firms

The literature concerned with the relationship between performance and information and communications technology (ICT) is usually focused on the ICT investments. This paper shows that it is the level of use of ICT within organisations, with preference as regards the expenses of ICT, which is responsible for the effect on performance. A general sample of 2255 Spanish companies has been used. Firms’ performance is measured as technical efficiency, which is determined by a data envelopment analysis (DEA), in which special attention is paid to the problem of the outliers. Finally, the analysis of the level of use of ICT is focused on a key area of the organisations, the supply chain, which affects the technical efficiency of the firms analysed. Results show that there is evidence of a positive effect of the use of ICT on technical efficiency. This effect is especially notable at intensive use levels in activities related to operations/manufacturing, purchasing or sales.     

On regulations for 5G: Micro licensing for locally operated networks

Future 5G networks aim at providing new high-quality wireless services to meet stringent and case-specific needs of various vertical sectors beyond traditional mobile broadband offerings. 5G is expected to disrupt the mobile communication business ecosystem and open the market to drastically new sharing based network operational models. 5G technical features of network slicing and small cell deployments in higher carrier frequencies will lower the investment barrier for new entrants to deploy local radio access networks and offer vertical specific services in specific areas and allow them lease the remaining required infrastructure on demand from mobile network operators (MNO) or infrastructure vendors. To realize the full vision of 5G to benefit the society and promote competition, innovation and emergence of new services when the 5G end-to-end network spans across different stakeholders administrative domains, the existing regulations governing the mobile communication business ecosystem are being refined. This paper provides a tutorial overview on how 5G innovations impact mobile communications and reviews the regulatory elements relevant to 5G development for locally deployed networks. This paper expands the recent micro licensing model for local spectrum authorization in future 5G systems and provides guidelines for the development of the key micro licensing elements. This local micro licensing model can open the mobile market by allowing different stakeholders to deploy local small cell networks with locally issued spectrum licenses ensuring pre-defined quality guarantees for the vertical sectors’ case specific needs.     

创新团队公平感知与知识共享行为关系研究——以成员信任为中介变量

创新团队组织形式的蓬勃发展使得团队成员的绩效激励方式成为众多管理者的研究课题。团队中掌握独特隐性知识的成员往往不愿意共享自身的有利于团队的创新知识,从而给团队的发展带来困难。如何针对这类员工做出有利于团队整体绩效提升的激励活动,是创新团队管理者和所有创新团队工作模式研究者的共同目标。通过数据模型的回归,得出如下结论:创新团队的成员公平感知与成员知识共享行为正向相关,成员对互动公平的感知对知识共享行为的影响最为显著。验证了创新团队成员信任在成员公平感知与知识共享行为之间的中介效用。     

企业员工知识分享媒介及其对工作效果的影响——以财会人员为例

通过对财会人员的访谈,将知识分享媒介划分成五种类型:各式书面信息、正式制度下的人际接触、正式制度下的信息科技、非正式制度下的人际接触以及非正式制度下的信息科技。一般企业在进行知识分享时会遇到知识流失与被盗取的障碍。知识分享媒介的性质不同,所能增进的工作效果亦有所不同。正式制度的人际接触是最普遍的,深获企业员工的好评,其所能增进的工作效果非常多元;非正式制度的信息科技,则视员工个人的使用习惯与学习态度而定,对于各项工作效果的提升情形差异很大。

证券交易信息系统与交易运行模式辨析

首先对证券交易信息系统的特性进行了阐述,介绍了证券公司交易系统的主要模式。现行的证券交易系统主要分为两类:以单营业部为基础的独立式交易系统和以中心营业部为基础的集中式交易系统。两种不同特性的交易系统又决定了不同的证券交易运行模式,文章的重点在于对不同的交易模式进行对比分析,并结合实际运行情况,找出能适应证券公司发展的、行之有效的交易模式。最终的结论是集中式交易模式是适应市场发展和公司经营的正确选择。
