This paper deals with on-line computation—or step-wise learning—of Pareto optimal insurance contracts. Our approach tolerates that the loss distribution might be unknown, intractable, or not well specified. Thus we accommodate fairly inexperienced parties. Losses are here simulated or observed, one at a time, and they cause iterated revisions of the premium. The mechanical and global nature of probability calculus thereby yields to more tentative, myopic procedures, possibly closer to how humans operate or reason in face of risk. Sequential revisions may also reduce the expense of insurers' time and money in seeking sufficient statistics. Emphasized below is the remarkable simplicity and stability of the resulting adaptive procedures. Special attention goes to catastrophic risks, and to subsidized or competitive insurance. 相似文献

Analysis of the US cruise line industry 总被引:1,自引:0,他引:1
J. S. Perry Hobson 《Tourism Management》1993,14(6)
The cruise line industry has been through a metamorphosis. From being a declining mode of travel in the 1960s, the cruise line industry turned the corner in the 1970s and became one of the fastest growing segments of the wider tourism industry during the 1980s. This paper examines the reasons behind this growth, the current structure of the US cruise industry and the issues facing the industry in the 1990s as it heads towards the next century. 相似文献

There has been an extensive body of research conducted into the technical aspects of the just-in-time (JIT) manufacturing methodology, particularly prior to 1990. It is only in more recent times that the focus has turned toward the more subtle people-related aspects. The recognition of JIT as a truly holistic approach to managing manufacturing operations has led to an appreciation of the importance of the role played by the human variable as well as an emphasis on the impact that organisational structure and management style can have on successful operation. This article examines and analyses the content of a wide range of articles related to issues such as: the need for change in corporate culture, the role of organisational structures, factors significantly impacting chances of success, the importance of employee involvement, how best to involve employees, the importance of training, how/whom/when to train, different team-based organisational structures, the impact of changing roles on various levels of the organisation and the appropriateness of particular change management strategies. An overall picture of the current state of thinking on these issues is thus developed and the importance of these factors to the successful implementation and operation of JIT highlighted. Opportunities for further research in this important area are identified. 相似文献

This paper presents the development andvalidation of new measurement tools to exploreself-efficacy toward service and toward civicparticipation. We developed and administereda survey to 851 students in an AACSB-accreditedcollege of business at a comprehensive publicuniversity located in the Midwest. Traditionalscale development methodologies plusconfirmatory factor analysis and simultaneousfactor analysis in several populations wereused to analyze both a primary sample and aholdback sample. Results strongly support thevalidity and reliability of the surveyinstrument. Future use for the instrumentincludes verification of the effectiveness ofpedagogies designed to increase self-efficacytoward service and motivation for civicparticipation in business students. 相似文献

The author addresses the question of how to use value-learning processes to integrate corporate social responsibility (CSR) in organizations as an interesting challenge in (higher) education. Two strategies have been proposed for the issue of CSR: a compliance strategy and a cultural change strategy (Karssing, 2001). This article focuses on the ethical and philosophical presuppositions of these different approaches. The incorporation of CSR in organizations cannot be accomplished by means of a compliance strategy only. Rather, it needs to be supplemented by a strategy aimed at stimulating a transformation process on the corporate culture level. The perspective of change through dialogue is proposed as a means of innovating the curriculum and the primary processes of student education. This organizational change perspective is demonstrated by describing how (ethical) reflective aspects are integrated in the curriculum of the Free University of Amsterdam. An additional case study on organizational value learning is presented to illustrate the thesis that CSR presupposes that university is an adequate context where life-long learning begins. 相似文献

The margin system is the first line of defense against the default risk of a clearinghouse. From the perspectives of a clearinghouse, the utmost concern is to have a prudential system to control the default exposure. Once the level of prudentiality is set, the next concern will be the opportunity cost of the investors, because high opportunity cost discourages people from hedging futures, and thus defeats the function of a futures market. In this article, we first develop different measures of prudentiality and opportunity cost. We then formulate a statistical framework to evaluate different margin‐setting methodologies, all of which strike a balance between prudentiality and opportunity cost. Three margin‐setting methodologies, namely, (1) using simple moving averages; (2) using exponentially weighted moving averages; (3) using a GARCH approach, are applied to the Hang Seng Index futures. Keeping the same prudentiality level, it is shown that the one using a GARCH approach by and large gives the lowest average overcharge. © 2004 Wiley Periodicals, Inc.

This paper examines a wide range of issues relating to the mix between loans and grants as well as the degree of concessionality of loans. A number of empirical tests are carried out based on annual panel data over 1970 to 1999 for 22 donor countries and 72 recipient countries. Based on the tests, we observe that for bilateral donors, past grant‐loan mix (and, hence, reflows from past transfers) do not influence the volume of current resource transfers. Our tests also show that the rate of official borrowing by the recipients (and, by deduction, the extent of their past debt burden) is positively influenced by the extent of the concessionality of such loans – irrespective of whether it is in the form of subsidised interest rates or longer grace periods. The paper concludes with a review of the circumstances in which grants, soft loans and non‐concessional loans might have their respective comparative advantage, as well as a discussion of the need, so as to overcome the negative incentive problems of soft loans, for a typical concessional loan package to be separated into two constituent parts. This would enable the recipient to be given the grant component and the option to take from the non‐concessional loan component as much as desired. 相似文献

Vendor Managed Inventory (VMI) involves the vendor making the replenishment decision for products supplied to a customer based on various inventory and supply chain policies. Information sharing between supply chain members is required in VMI. Sometimes VMI decisions are delayed and/or the information shared is inaccurate. This research examines the effects of information delay and accuracy, and the sharing of sales and forecast information in a VMI environment facing stationary and nonstationary demand. The simulation experiments show the impact of information delay, information inaccuracy, and information sharing on a variety of performance measures, including inventory levels and fill rates. 相似文献

This study examines how two dimensions of strategic orientation (customer and competitor orientation) influence logistics and market performance. Two capabilities, operational flexibility and collaboration, are studied. Data were collected from manufacturers working with third party logistics providers. The findings suggest that customer and competitor orientations have different influences upon performance when leveraged through the capabilities. Competitor orientation, while having a detrimental direct effect on logistics performance, appears to be the better strategic approach, when supported with operational flexibility since it results in enhanced logistics (efficiency) and market (effectiveness) performance. Customer orientation, on the other hand, greatly improves logistics performance, i.e., internal efficiency. 相似文献

Several papers have been published demonstrating the positive effects a single, reputable ally has on evaluations of a focal brand. Interestingly, little research has been published examining the effects of multiple brand allies. We examine the effect of an alliance with two, one, or zero well-known brand allies on evaluations of a previously unknown focal brand. The presence of a single brand ally significantly increased perceived quality and hedonic and utilitarian attitudes. While multiple alliances improved focal brand evaluations relative to the no ally condition, the second ally did not increase evaluations relative to the single ally condition. 相似文献
