E-business processes between insurance companies and their private customers allow — in comparison to conventional business processing — savings in administrative expenses up to 30 per cent. However, today’s e-business processes are often described as little transparent and stereotyped. Users, therefore, complain them being far to complex and, as a consequence, do not accept them. Relating to research in the field of customer behaviour, it has been proved that even in e-business processes customers like to be contacted and treated individually. This can be reached by corresponding to the cognitive ability and the personal involvement of each customer. By using those mechanisms information processing becomes ?hospitable‘ or even ?human-alike‘. Chatter-bots simulate human behaviour in e-business processes and will possibly replace personnel in certain areas. Therefore, chatter-bots seem a suitable instrument to introduce successfully e-business processes between insurance companies and their private customers. Two positive consequences could be reached: first, process efficiency could be raised and second, cost-savings in processing could be gained. 相似文献

本文回顾了适用于严格固定货币汇率的技术方法,并从对货币联盟通过货币汇率严格固定所获得的利益与付出的代价的研究中给出证明。事实上,丧失货币主权而付出的代价由于有效资本市场和劳动力市场的形成而降低了。本文还讨论了一个被忽略的实行严格货币固定的好处,即小国因此而事受到更好的货币政策。完善的货币政策得以形成是因为小国将其货币主权交托于大型机构(大国央行或是货币联盟央行)后,其货币政策将免受政治因素的影响;另外部分原因在于大型机构拥有更多的金融和人力资源去设计和执行最佳的货币政策。由于在联盟内部实行区内贸易和资本流动,因此即便太央行的货币政策出错。对于它所服务的成员国来说,造成的影响也较小。 相似文献

The amount of customisation to an enterprise resource planning (ERP) system has always been a major concern in the context of the implementation. This article focuses on the phase of maintenance and presents an empirical study about the relationship between the amount of customising and the resulting support effort. We establish a structural equation modelling model that explains support effort using customisation effort, organisational characteristics and scope of implementation. The findings using data from an ERP provider show that there is a statistically significant effect: with an increasing amount of customisation, the quantity of telephone calls to support increases, as well as the duration of each call. 相似文献

In today's tough economic environment, governments at all levels face significant budget shortfalls and public rail transit systems must compete with other public services for government subsidies. It is critical that public rail transit systems be concerned with their operational performance and efficient use of resources. In this paper, we develop a methodology that measures a rail transit system's performance relative to that of other rail transit systems, compares its performance to an appropriate efficient benchmark system, and identifies the sources of its inefficiency. We analyze the relationship between public subsidies and operational performance of public rail systems and show an inverse relationship between subsidization and efficiency. 相似文献

This research examines the effect of the abolition of user fees in South Africa, a policy implemented in 1994 for uninsured children under the age of six and the elderly uninsured, as well as pregnant and nursing mothers. The analysis focuses on the implementation of the policy and the use of curative public healthcare services by children following strict and fuzzy regression discontinuity designs. The estimates point to statistically insignificant average and local average policy effects, even though the policy appears to have been implemented reasonably effectively, albeit imperfectly. In other words, the policy did not, on average, affect the use of curative public healthcare, at least for those children who should have benefited from the policy. 相似文献

Internal rate of return (IRR) is one of the most common and important indicators in investment analysis because it is often used by managers and practitioners as a decision-making criterion. Moreover, the IRR reflects the financial cost in financing decisions and it helps to answer the following question when comparing different financing alternatives: “Which loan is the cheapest?” Among the different types of loans in Brazil, there is a financial product called a prepurchase financing pool (PPFP) that is generally regarded as the best option for financing or loans. The objective of this article is to use the prepurchase financing pool to show the flaws of IRR in financial analysis. In particular, when IRR is used to evaluate the prepurchase financing pool, one finds problems of reliability regarding (i) existence, (ii) uniqueness, and (iii) economic interpretation of the rate. The results show that the prepurchase financing pool is relevant evidence that the IRR flaws are found in financial products. 相似文献

By the start of the twenty‐first century, the once dominant historical downtown core of Johannesburg had lost its privileged status as the center of business and commercial activities, the metropolitan landscape having been restructured into an assemblage of sprawling, rival edge cities. Real estate developers have recently unveiled ambitious plans to build two completely new cities from scratch: Waterfall City and Lanseria Airport City (formerly called Cradle City) are master‐planned, holistically designed ‘satellite cities’ built on vacant land. While incorporating features found in earlier city‐building efforts, these two new self‐contained, privately‐managed cities operate outside the administrative reach of public authority and thus exemplify the global trend toward privatized urbanism. Waterfall City, located on land that has been owned by the same extended family for nearly 100 years, is spearheaded by a single corporate entity. Lanseria Airport City/Cradle City is a planned ‘aerotropolis’ surrounding the existing Lanseria airport at the northwest corner of the Johannesburg metropole. These two new private cities differ from earlier large‐scale urban projects because everything from basic infrastructure (including utilities, sewerage, and the installation and maintenance of roadways), landscaping, security services, the regulation of common spaces, and selling and branding the city are firmly in the hands of private profit‐making corporate entities and outside the mandate of public authorities. 相似文献
