In this paper we give upper bounds for both the Value at Risk VaR α , 0 < α < 1 , and for ruin probabilities associated with the supremum of a process driven by a Brownian motion and a compound Poisson process. We obtain lower bounds for the same Value at Risk, and for different cases we discuss the behavior of the bounds for small α. We prove our bounds are "asymptotically" optimal, as α tends to zero. The ruin probabilities obtained are related to other bounds found in recent literature. 相似文献

This paper is an analysis of the likelihood for repeat visits to a sun and sand destination by tourists. For this purpose, an empirical study was conducted using tourists who had visited the destination. The analysis took into account the travelling group composition. The results showed that, for the total tourist sample, overall satisfaction had the biggest influence on the decision of whether to revisit a destination, while the least important influence was the tourist's perceived image. These influences varied, however, when different travelling group compositions were considered. The results are of vital importance in tourism management policies, because they can contribute to the better design and development of tourism promotion strategies. 相似文献

Although NPD collaboration with external partners has become the next generation in NPD practice, the discussion concerning how to organize collaboration so as to obtain better results is far from over. Since communication is the most important element in successful interfirm exchange, this study focuses on the impact of collaborative communication and its facets—frequency, formality, reciprocal feedback, and rationality—on NPD collaboration results. In order to explain how collaborative communication can best be managed to enhance NPD collaboration results, this research combines the relational and resource‐based views, proposing the existence of two routes of influence: the direct resource‐based route and the indirect relational route mediated by trust. Using a sample of 207 NPD collaboration projects of innovative firms, empirical findings indicate that reciprocal feedback–rationality and frequency play an important role in product quality and adherence to budget and schedule, respectively, even without trust. Moreover, the trust between partners substantially reinforces the positive influence of reciprocal feedback–rationality on NPD collaboration results and makes the effect of formality significant. Therefore, the two alternative routes are confirmed as important paths to new product success, which provides relevant managerial implications. 相似文献

Research design is quasi-experimental, field, with four longitudinal assessments for two groups (one experimental and one control) of students with irregularity student. Intervention, learns listen-think-write (lltw) method. population, 488 students. With a sample conditioned (students with irregular registration) of 170 students from two university careers of accounting and administration, both manner, 24.3 years old.

The impact obtained by the intervention (LLTW) was 23%, significant difference between follow-up evaluation 6 and 12 months. Regarding the improvement of learning skills in post-test measurement showed a general increase in average by 28%. Also it is necessary to say, the decline was failed subjects in the two groups evolving 12 months in control group was 3 to 4 and the experimental group was 1 to 2. 相似文献

On the Asymmetric Recognition of Good and Bad News in France, Germany and the United Kingdom 总被引:1,自引:0,他引:1
We investigate whether accounting systems recognise bad news more promptly in earnings than good news, where news is proxied by changes in share price. The analysis is based on a sample of firm/years drawn from France, Germany, and the UK during 1990 to 1998. These three countries are the originators of three distinct legal traditions. Previous studies have argued that asymmetric recognition, one manifestation of conservative accounting, is sensitive to legal background and history. We find that in all three countries the contemporaneous association between earnings and returns is much stronger for bad news (i.e. when price changes are negative) than for good news, and although the results are strongest for the UK, and then France, the inter-country differences are not statistically significant. The stronger reaction to bad news is more pronounced for firms with relatively low capitalisation. We also find that the relative persistence of profits and losses are consistent with asymmetric recognition in France and the UK, but not in Germany, and that the more timely recognition of bad news is maintained even when we control for earnings persistence. When we extend the model to include price changes from previous periods, we see that the stronger reaction to bad news decays over time. The results from this model also suggest that 'pervasive' conservatism, unrelated to news, is observed in Germany and France, but the UK results are consistent with optimism. Although asymmetric recognition is generally strongest in the UK and weakest in Germany, and this broadly conforms to our expectations, the differences are less clear than the results from earlier periods. 相似文献

This article is an introduction to the selection of papers on "Business Ethics in Spain" included in this monographic issue of the Journal of Business Ethics. Specifically, this article is a survey of the development of the social, political, cultural and economic background of business in Spain since 1940, in order to show how the ethical values, attitudes and problems of the Spanish managers changed in these years. First, the global evolution of this background is explained, and then several relevant problems are discussed, namely those of the attitudes of business towards the State and the law (with an aside on the attitudes of society towards profit and wealth), corruption, and the grey economy, taxes, and irregular labour. The article concludes with a survey of the scientific developments of business ethics in Spain. 相似文献

This study reports the results of an experiment that analyses the behavioural effect of relative performance feedback (RPF) on individual performance when compensation is based on team performance. Specifically, it investigates whether RPF affects individual performance differently when the comparison focuses on other members of that individual’s team (within-group RPF) or on other teams (between-group RPF). We predict a negative effect of within-group RPF on individual performance. We also predict that between-group RPF moderates that negative effect, since it encourages individuals to focus on group goals rather than individual goals. Consistent with our predictions, results show that the negative effect of within-group RPF on individual performance is mitigated by between-group RPF. Our results can help accountants to better understand how the effects of relative performance feedback differ according to the predominant comparison target. 相似文献

AbstractThis study investigated the importance given by two groups of pre-service teachers of primary education from Spain and Portugal to seismic risk in a framework of different natural risks, both in personal terms and as future teachers. A questionnaire was used for data collection. Some questions about the seismic phenomenon were also included. The sample groups consisted of 110 students from an institution in Spain and 121 from one in Portugal. Both institutions are in cities affected by the historic Lisbon earthquake of 1755. The results showed that the risk of forest fire was the first choice for classroom study in both cases. The Spanish group was also more focused on the importance of other risks like flood and drought. The Portuguese group showed a greater concern with seismic risk, frequently referring to their own historic earthquake of 1755. A few gaps in knowledge concerning earthquake prediction and comparing seismic risk in different regions of their own countries were also found. In accordance with the results, it is suggested that training courses for primary school teachers should include Disaster Risk Education in Science Education for a better understanding of the impact of various hazards and a greater concern with seismic risk due to its particular features, especially in regions where the seismic pattern is characterized by long seismic cycles with major earthquake episodes. 相似文献
