This study considers the linkage of the Russian equity market to the world market, examining the international transmission of the Russia's 1998 financial crisis utilizing the GARCH–BEKK model proposed by Engle and Kroner [Engle, R.F., Kroner, K.F., 1995. Multivariate simultaneous generalized ARCH. Economet. Theor. 11, 122–150]. We find evidence of direct linkage between the Russian equity market with regards to returns and volatility, while the weakness of the linkage suggests that the Russian equity market was only partially integrated into the world market. At the time of the crisis, evidence of contagion is clear. 相似文献

Can Normality of Yields Be Assumed for Crop Insurance? 总被引:2,自引:0,他引:2
Normality of crop yield residuals pooled to the state and regional level is examined using a procedure that accounts for trend and heteroscedasticity. Normality tests are conducted using farm-level yield data from over 200,000 producers of six crops in seven U.S. states. The results indicate consistent non-normality of crop yields. The effects of assuming normality on insurance premium rates are examined. Assuming normality is found to generate premiums that can differ substantially from premiums derived using data-based empirical distributions.

Les auteurs ont analysé la normalité du rendement résiduel des cultures à l'échelon de l'État et à l'échelon régional au moyen d'une méthode tenant compte des conjectures et de l'hétéroscédasticité. Ils ont utilisé les données sur le rendement fournies par plus de 200 000 cultivateurs produisant six cultures dans sept États américains pour effectuer des tests de normalité. Les résultats révèlent l'anormalité constante des rendements. Les auteurs s'interrogent sur les conséquences d'une normalité hypothétique sur les primes d'assurance. En supposant des rendements normaux, on obtient des primes sensiblement différentes de cedes calculées avec une distribution empirique des données. 相似文献

A dynamic bio‐economic model is used to show that, without technological and policy intervention, soil loss levels, income and nutrition could not be substantially or sustainably improved in a highland area of Ethiopia. Although cash incomes could rise by more than 40% over a twelve‐year planning period, average per ha soil losses could be as high as 31 tonnes per ha. With the adoption of an integrated package of new technologies, however, results show the possibility of an average two‐and‐a‐half‐fold increase in cash incomes and a 28% decline in aggregate erosion levels even with a population growth rate of 2.3%. Moreover, a minimum daily calorie intake of 2000 per adult equivalent could be met from on‐farm production with no significant increases in erosion. However, higher rates of growth in nutritional requirements and population introduce significant strains on the watershed system. From a policy perspective, there is a need for a more secure land tenure policy than currently prevailing to facilitate uptake of the new technology package, and a shift from the current livestock management strategy to one that encourages livestock keeping as a commercial enterprise. It would also imply a shift to a more site‐specific approach to land management. 相似文献

Money donations intentions among Muslim donors: an extended theory of planned behavior model 下载免费PDF全文

- The investigation into determinants of money donation intentions while employing an extended theory of planned behavior model is limited to developed country contexts. However, given the challenges facing charitable organizations and scant theoretical evidence from developing world, such an examination can contribute pragmatically. The current study establishes the impact of subjective norms, perceived behavioral control, past behavior, and attitude on respondents' money donation intentions to charities in Pakistan. The respondents (N = 223), a non‐student population living in the city of Gujranwala, completed a survey. The collected data are analyzed by means of a multivariate analysis, which was comprised of regression and correlation. The results reveal a strong support to the extended theory of planned behavior model in establishing the relationship between identified independent and dependent variables in a developing country context of Pakistan. The study contributes to the establishment of a few strategies, which are useful for managers working in charitable organizations to attract and retain donors to support several causes.

AbstractIn the era of the Internet and networking, stakeholders increasingly acquire power by influencing brand value and meanings. However, this does not imply that marketing managers have lost their power over brand creation and management. Thus, the aim of this study is to explore brand power relationships taking the co-evolutionary perspective as conceptual lenses. In particular, this article seeks to address the competitive relationship between the corporation and its stakeholders in determining the corporate brand evolution over time, suggesting that corporate brand management is successful when co-evolving power relationships are established. The relational interplay between managers and stakeholders is framed into the Brand Power Relationship Model that suggests four potential evolutionary paths. It offers new brand typologies supported by examples from business practices, which mirror four different ways of managing and adapting brands over time; namely, through the None’s Brand, the Managers’ Brand, the Stakeholders’ Brand, and the Co-Evolutionary Brand. Focusing on the latter, this study depicts managers and stakeholders as having reciprocal influences and co-determining themselves, thus triggering interrelated relational effects that influence corporate brand evolution over time. The bilateral power of managers and stakeholders is framed into a further model, focused on corporate brand co-evolution. It is proposed that corporate brands can successfully co-create their value and meanings over time only if corporations co-evolve with their environment—in this study, multiple external stakeholders. 相似文献

The importance of information retrieval systems is unquestionable in the modern society and both individuals as well as enterprises recognise the benefits of being able to find information effectively. Current code-focused information retrieval systems such as Google Code Search, Codeplex or Koders produce results based on specific keywords. However, these systems do not take into account developers’ context such as development language, technology framework, goal of the project, project complexity and developer’s domain expertise. They also impose additional cognitive burden on users in switching between different interfaces and clicking through to find the relevant code. Hence, they are not used by software developers. In this paper, we discuss how software engineers interact with information and general-purpose information retrieval systems (e.g. Google, Yahoo!) and investigate to what extent domain-specific search and recommendation utilities can be developed in order to support their work-related activities. In order to investigate this, we conducted a user study and found that software engineers followed many identifiable and repeatable work tasks and behaviours. These behaviours can be used to develop implicit relevance feedback-based systems based on the observed retention actions. Moreover, we discuss the implications for the development of task-specific search and collaborative recommendation utilities embedded with the Google standard search engine and Microsoft IntelliSense for retrieval and re-engineering of code. Based on implicit relevance feedback, we have implemented a prototype of the proposed collaborative recommendation system, which was evaluated in a controlled environment simulating the real-world situation of professional software engineers. The evaluation has achieved promising initial results on the precision and recall performance of the system. 相似文献
