This paper studies capital market integration in Middle Eastern and North African (MENA) countries and its implications for international portfolio investment allocation. Starting with four cointegration methodologies, we significantly reject the hypothesis of a stable, long-run bivariate relationship between each of these markets and the European Monetary Union (EMU), the United States, and a regional benchmark. This indicates the existence of significant diversification opportunities for three categories of investors (EMU, world, and regional investors). A recursive analysis based on Barari (2004) suggests that recently, the MENA markets have started to move toward international financial integration. Investigating the effect of selected financial, economic, and political events on such a process, we extend the methodology and find that the markets react heterogeneously to the different categories of shocks. They should therefore not be treated as a bloc for global allocation purposes. Finally, after adjusting the integration levels by relative market capitalization, Israel and Turkey are the most promising markets in the region, followed by Egypt, Jordan, and Morocco. Tunisia and Lebanon seem to be lagging behind. 相似文献

交叉销售视角下企业多元化战略风险研究 总被引:1,自引:0,他引:1
交叉销售在服务业和高科技行业的兴起,使得越来越多的企业开始从事基于交叉销售的多元化战略.这类多元化战略同时具有多元化战略的一般性特征,又带有交叉销售背景下的特殊性.本文在对多元化战略的风险及交叉销售相关研究加以逐一回顾的基础上,对基于交叉销售的多元化战略与一般性多元化战略的差异进行了比较,并对其所具有的风险进行了深入的探讨. 相似文献

笔者对在大学英语课堂教学中定期开展性教育的课程设计、教学方法、作业的实施以及学生在教学中的反应与意见进行了调查研究。研究发现,在大学英语教学课堂中适时对学生进行性教育,不仅可以培养学生形成正确、健康的性价值观,而且还能使学生在了解西方性文明的同时提高其学习英语的兴趣。由此可见,在我国大学生性教育需求日益凸显的今天,将正确的性知识、性观念、性道德及两性相处的知识融入到大学英语教学中,构筑多元化大学生性教育平台是必要和迫切的。 相似文献

Analyses were carried out on financial compensation to avoid loss of tropical forests and related carbon (C) emissions when marginal financial yield declined for land-use options with extended areas, and when a risk-averting perspective (modeled according to financial theory around the capital asset pricing model) is assumed. The approach in this study was to consider natural forest, forest plantation, pasture, and cropland simultaneously to investigate how an optimized land-use distribution may reduce the amount of compensation necessary to avoid C emissions from forest loss.The financial compensations derived were as high as US$ 176 per hectare per year when comparing natural forests only with the most profitable alternative (croplands). However, compensation decreased to US$ 124 for risk-neutral decision-makers, who would strive for optimized land-use allocation, and to only US$ 47 per hectare per year for risk-avoiders, who would look to maximize the reward-to-variability ratio. Sensitivity analyses indicated that the compensation under risk-aversion increased much less than under risk-ignoring when increased productivity of agricultural land-use or growing demand for agricultural products was simulated. It was concluded that considering appropriate diversification strategies and the well documented human behavior to avoid risks is an important step in developing cost-effective compensation policies. 相似文献

In this study, we provide support for the argument that patents are at their maximum value at those times when they are under litigation. We develop a heuristic procedure to determine the way in which such patents under litigation form a network of patent family members, and then go on to examine the priority patents involved. We subsequently attempt to develop a simple procedure to further identify both the ‘critical’ and ‘significant’ chains within our proposed patent priority network. We suggest that the ‘critical’ and ‘significant’ chains that are created within the above network provide companies with important information which will ultimately provide them with valuable support for the subsequent decision of their patent portfolio strategies. 相似文献
