基于时变参数Copula的ΔCoVaR度量技术

采用基于时变参数Copula的ΔCoVaR度量方法,以动态参数Copula模型描述金融变量间的相依结构、以GARCH类模型描述各金融变量的边际分布,通过构建的联合分布计算ΔCoVaR。利用此方法度量中国大陆与美国、香港的股票市场间的极端风险溢出。实证结果表明:通过此方法计算的ΔCoVaR能同时反映时变波动性与时变相依性,可更灵敏准确地度量危机时的极端风险溢出。     

基于VaR风险控制的半log-最优资产组合模型

通过建立基于VaR风险控制下的单周期半log-最优资产组合数学模型,证明了最优解的存在性与唯一性。利用遗传算法对半log-最优资产组合模型进行了实例计算与分析,并与log-最优资产组合模型进行了比较,结果表明半log-最优资产组合模型具有计算方便的特征。     

风险社会背景下大学生的信仰危机

当今,世界正由工业社会向风险社会过渡,信仰危机是当代人类面临的全球性问题,信仰危机的出现要求我们关注信仰教育。受全球化的影响,中国也处于风险社会之中。大学生作为我国社会主义事业的接班人,其信仰状况直接关系到国家的前途和命运。本文首先阐述了信仰以及信仰危机的含义,然后分析了我国大学生当前存在的信仰危机及其产生的原因,最后对于解决我国大学生的信仰危机提出了几点建议。     

中国老年人虚弱指数与死亡风险及队列差异

利用中国老年人健康长寿影响因素调查（ CLHLS ）2002－2011年跟踪调查数据,通过多种健康指标构建中国老年人虚弱指数,运用增长曲线模型和Cox等比例风险函数的研究方法,对中国老年人虚弱指数和死亡风险及其队列差异进行了深入分析。研究发现,女性虚弱指数比男性高,增长速度也比男性快,但是死亡风险比男性低;出生较晚的队列与出生早的队列相比,虚弱指数会更高,他们的增长程度更快;受教育程度高的老年人虚弱指数低,但是其增长速度却比受教育程度低的老年人要高。     

Transfer Pricing in Transition Economies: Evidence from Ukraine

Faced with possibilities and challenges of doing business under different regulatory regimes, transnational corporations have developed a number of transfer mechanisms to take advantage of profit maximization opportunities. Transfer pricing is a transfer mechanism widely used by transnational corporations. Implications of transfer pricing for profitability and the need for transfer pricing regulation are well understood by national governments, which is reflected in the fact that more than 60 governments have introduced some form of transfer pricing controls. Transfer pricing is a challenging issue for transition economies as their transfer pricing regulatory systems are less mature than those of developed countries. The authors have initiated an empirical study on transfer pricing strategies in the Ukrainian market. In addition, the national regulatory regime for transfer pricing was evaluated compared to international best practices. This article is an attempt to draw attention of the research community and Ukrainian policy-makers to transfer pricing issues in Ukraine.      

释放国债风险的策略选择

改革开放以来 ,我国重新启动公债的发行。特别是 1 994年以来 ,政府债务收入迅速增长 ,成为政府可支配资源的重要组成部分。公债作为政府调控市场、应对经济周期的重要手段 ,起到了非常重要的作用。如何判断我国的政府债务收入 ,确定适度的国债规模和发债空间 ,释放国债风险 ,是一个不容忽视的问题     

建立河南省高新技术产业风险投资体系的设想

河南省发展风险投资有十分重要的现实意义。为此,我们要多渠道开辟风险投资来源,实现投资主体多元化;积极发展风险投资基金;鼓励发展风险投资公司;培养既精通金融又懂技术、熟悉实业投资的风险投资专门人才;开拓风险投资保险业务,并创造有利于风险投资的宏观环境。此外,在规范发展河南省风险投资过程中,还应注意将风险投资体系建立在市场经济机制基础上,按市场经济规律运作等问题。     

Gender roles,HIV risk behaviors,and perceptions of using female condoms among college students

The purpose of this study was to examine relationships between gender roles and HIV risk behavior, and perceptions and acceptance of the female condom among college students (n = 410). It was hypothesized that high hyperfeminine females and high hypermasculine males – those adhering to traditional gender roles – would engage in more HIV risk behaviors, including alcohol and drug use and various sexual practices, than those with lower hyperfemininity and hypermasculinity. It was also hypothesized that higher hyperfeminine females as well as higher hypermasculine males would perceive the female condom more negatively and would be less likely to view the female condom as a viable form of protection in the future. It was also hypothesized that high hyperfeminine females and high hypermasculine males would not accept the female condom as an alternative form of protection. Implications for prevention interventions are discussed.     

防范和化解地方政府债务风险研究

针对目前中国在防范与解决地方政府债务风险、完善社会保障体系、缓解现实债务压力和潜在财政风险、缓解其与社会经济稳定之间的矛盾中存在的问题,提出了防范和化解地方政府债务风险的建议,从而建立一套科学的防范政府债务风险的机制,强化地方财政风险预警体系,实行政府债务报告制度,确保政府债务始终处于安全线之内。     

风险社会理论视角下政府危机管理能力创新的思考

风险社会理论重塑着人类的风险意识与危机应对观念,如果说危机意识有助于我们防患于未然,但风险的潜在性与不可避免性,风险与危机的不可控性与紧急性,让我们在突发的危机到来时,不能不直面风险与危机。我国现行危机管理机制刚刚起步,公共危机的突发性、紧急性与危害性,决定了在危机爆发之后,公共危机管理中应急协调机制的健全是应急处理阶段的关键环节与核心所在。而现行危机管理应急机制的健全既包括应急管理机构设置,也应包含应急机制功能的有效发挥,其中政府“应急协调”专业化能力的增强是有效发挥应急机制功能的重要途径。
