外资企业财务的汇率风险管理分析

近年来,在人民币升值预期的背景下,中国的外资企业面临着前所未有的汇率风险,因此,企业的汇率风险财务管理就具有了重要的理论价值与现实意义。基于外汇资产与负债的敞口风险管理和金融衍生工具的应用,针对外资企业财务的汇率风险进行了深入分析。结合外资企业的经济业务数据,对汇率风险管理进行了实证检验,并对外资企业如何降低汇率风险损失提出了相关的建议。     

人民币升值与中国国际贸易顺差的相关性分析

近年来,中国国际贸易呈现出显著的顺差趋势,这引起了国际贸易逆差国对人民币汇率的指责:人民币汇率低估导致其廉价的出口商品占据他国市场.事实上,一国的客观经济基础决定了其汇率对国际贸易的影响.而人民币汇率是由客观经济基础自发形成的,不存在任何形式的操纵.选取2005-2009年的宏观经济数据,针对人民币升值与国际贸易顺差的相关性进行了深入分析,并对如何改善国际贸易格局提出了相关的政策性建议.     

Fine-scale conservation planning outside of reserves: Cost-effective selection of retention patches at final harvest

Retaining forest patches at final harvest is a key conservation measure in boreal forests, but guidelines for how to increase its cost-effectiveness are lacking. In a study in boreal Sweden, we compared the cost-effectiveness of three different approaches a forest owner may use to select patches: selection based on the conservation value of patches alone, economic cost alone or both of them combined. We also compared the cost-effectiveness of six different common types of patches. Conservation value was measured as species richness of bryophytes and lichens and as structural characteristics of patches. Compared to the selection approach in which both conservation value and cost were used, cost-effectiveness was 5-14% lower when only conservation value was used, depending on how conservation value was measured. On the contrary, using only the economic cost decreased the cost-effectiveness by only 1-2%. Among the patch types, swamp forest areas and deciduous tree groups were cost-effective types to retain. However, the patch types were complementary in their species composition and all hosted unique species. We argue that, ideally, assessments of both conservation values and economic costs of retaining patches should be made prior to harvest to enable planners to make well-informed and cost-effective decisions.     

大学生社会主义核心价值观内化的策略研究

市场经济条件下,多元文化的冲击使当代大学生的价值目标从理想主义趋向关注现实,使大学生的价值观念由集体主义趋向关注个人。在大学生价值观教育中,要实现社会主义核心价值观的内化,应坚持整体性原则,营造良好的育人环境;要发挥榜样激励作用,开展典型示范教育;要积极搭建社会平台,加强大学生社会实践;要创新教育形式,发挥新媒体的优势。     

酒店管理专业实习过程管理研究

专业实习是酒店管理专业学生学习过程中必不可少的实践教学环节,从形式上来说,几乎所有的酒店管理专业都比较重视专业实习环节,但通常情况下,实际的实习效果和预期的实习目标之间还存在着较大偏差。针对酒店管理专业实习现存的各种问题,通过问卷调查、实习日志阅读、师生交流等方式进行信息搜集和探索研究,意在为酒店实习的过程管理提供相应对策,改善实习效果,实现酒店管理专业的可持续发展。     

《大乘大义章》与印度佛教中国化

《大乘大义章》是研究罗什与慧远佛学思想的重要著作,也是研究印度佛教思想和印度佛教中国化的重要著作。《大乘大义章》显示出罗什与慧远在佛学思想上的差别,同时也反映出中印佛教文化在本质上的不同。这两种不同文化的冲突预示着印度佛教中国化的发展方向。     

Repeat‐Sales Indexes: Estimation without Assuming that Errors in Asset Returns Are Independently Distributed

This article proposes an alternative specification for the second stage of the Case‐Shiller repeat‐sales method. This specification is based on serial correlation in the deviations from the mean one‐period returns on the underlying individual assets, whereas the original Case‐Shiller method assumes that the deviations from mean returns by the underlying individual assets are i.i.d. The methodology proposed in this article is easy to implement and provides more accurate estimates of the standard errors of returns under serial correlation. The repeat‐sales methodology is generally used to construct an index of prices or returns for unique, infrequently traded assets such as houses, art and musical instruments, which are likely to be prone to exhibit serial correlation in returns. We demonstrate our methodology on a data set of art prices and on a data set of real estate prices from the city of Amsterdam.     

Non-convexities and the gains from concealing defenses from committed terrorists

How should countries defend against committed terrorists who attack until defeated? We identify a fundamental non-convexity—one only needs to defeat the terrorist once. Consequently, provided a country values targets similarly, it should conceal defenses and allocate defense resources randomly.     

CHH际资本流入的贸易增长效应分析

以汇率和经济增长作为国际短期资本影响国际贸易的中间变量,采用Eviews6．0,从总体上考察国际资本流入对我国进出口的影响。从模型得出,随着FDI的增加,我国的出口额会增加,进口额会减少,而短期内FDI的增加对我国的进出口都起着促进作用;人民币实际有效汇率的贬值无论在长期和短期都对出口起着促进作用,对进口起着抑制作用。因此,在国际资本大量流入的情况下,只有积极吸引FDI,有效防范短期资本大幅度波动,才能保持贸易收支的相对稳定。     

双边间接网络效应对平台产品扩散与定价的作用研究

本文在BASS扩散模型的基础上,引入双边间接网络效应的作用,建立平台产品的扩散模型。研究发现:双边间接网络效应产生潜在的市场规模扩张,其和市场单边自扩散共同作用,使得平台产品的扩散形态可能呈单峰或多峰形状。按双边扩散表现为相互制约还是相互促进,平台产品市场扩散可分为潜在市场规模扩张起飞前和潜在市场规模扩张起飞后两个阶段。平台运营者需要正确判断产品扩散所处的阶段,谨慎制定正确的定价策略。
