美国银行信用风险与宏观经济变量的实证研究

以2005年到2012年美国综合银行不良贷款的相关数据为样本，对影响美国银行信用风险的宏观经济变量进行实证检验。研究结果表明：美国综合银行的信用风险水平比较高，其信用风险水平与失业率有着显著的强正相关关系，而与 GDP增长率、消费者物价指数增长率、生产者物价指数增长率和广义货币增长率无关。实际上，美国银行业的信用风险经过金融衍生品分散转化后并没有消除，只是被隐藏起来了，并且逐步累积。有鉴于此，提高我国银行业信用风险管理水平措施包括：一是着重研究宏观经济波动以及政策的实施对信用风险的影响；二是提高就业率，保持宏观经济环境的良好状态；三是借鉴西方发达国家较为成熟的理论体系，形成适合我国的风险管理控制方法；四是提高对住房贷款业务的风险认识；五是重视信用文化建设和银行信用制度创新。     

Morality and Nuclear Energy: Perceptions of Risks and Benefits,Personal Norms,and Willingness to Take Action Related to Nuclear Energy

We examined factors underlying people's willingness to take action in favor of or against nuclear energy from a moral perspective. We conducted a questionnaire study among a sample of the Dutch population (N = 123). As expected, perceptions of risks and benefits were related to personal norms (PN), that is, feelings of moral obligation toward taking action in favor of or against nuclear energy. In turn, PN predicted willingness to take action. Furthermore, PN mediated the relationships between perceptions of risk and benefits and willingness to take action. In line with our hypothesis, beliefs about the risks and benefits of nuclear energy were less powerful in explaining PN for supporters compared to PN of opponents. Also, beliefs on risks and benefits and PN explained significantly more variance in willingness to take action of opponents than of supporters. Our results suggest that a moral framework is useful to explain willingness to take action in favor of and against nuclear energy, and that people are more likely to protest in favor of or against nuclear energy when PN are strong.     

Risk Perception in a Developing Country: The Case of Chile

In this work we characterize risk perception in Chile, based on the psychometric paradigm, exploring the difference between perceived social and personal risk. For this purpose, we conducted a survey including 54 hazards, 16 risk attributes, and 3 risk constructs. The survey, divided into four parts, was administered to 508 residents of Santiago, Chile. Using factor analysis, three main factors, which accounted for 80% of the sample's variance, were identified: factor 1, commonly called "Dread Risk" in the literature, explained 37% of variance; factor 2, "Unknown Risk," explained 28%; and factor 3, which we called "Personal Effect," explained 15% of the variance. On average, individuals perceived themselves as less exposed to risk and with more control and knowledge about them than the general population. OLS regression models were used to test the association of perceived risk with the three main factors. For social risk, factor 1 had the greatest explanatory power, while factor 2 had a negative sign. For personal risk, only factors 2 and 3 were significant, with factor 3 having the greatest explanatory power. Risk denial (defined as the difference between perceived personal and social risk) was associated with factors 1 and 2 only, with factor 2 having a negative sign. The difference between desired and actual regulation levels proved positive for all hazards, thus indicating that Chileans are dissatisfied with the current regulation level for all the hazards analyzed. The comparison of data at the aggregate and at the individual subject's level suggests that while the aggregate analysis overestimates the magnitude of the correlations it still reflects the tendency of the individual responses.

论我国股票市场的运行效率

股票市场的效率在于能够最大限度地融集资金并在产业和企业间进行有效分析；能够提供资金最大流动性，降低股票交易的成本，实现资源的有效配置。为此，必须从提高股票市场的效率入手，尽快完善我国股票市场的运行机制，使股票市场充分发挥资源配置和分散风险两大功能。     

高校举债办学风险分析及防范措施

随着高校招生规模的扩大,在校学生人数不断增加,原有的设施已不能满足目前学校发展的需要,高校为了吸引更多的人才,纷纷向银行大量举债,建设新校区和基础设施,高校贷款资金在改善高校办学条件、满足学生基本需求的同时,随着学校还贷高峰的到来和还贷能力的约束,巨额本息的支付使高校面临严峻的财务风险。因此,现在阶段必需规范高校贷款行为,强化高校举债规模的评估与控制,合理有效的使用银行信贷资金,防范和化解出现的各种风险。     

扶贫移民适应期生计风险、扶持资源承接与政策优化

扶贫移民兼具扶贫和生态保护功能,有效破解区域生态可持续和社会经济发展矛盾的同时也会出现目标的“反功能”现象。基于适应期扶贫移民生计特征归纳,寻求可能遇到的丧失发展资源、失去公共服务、社会关系网络受损、边缘化等生计损失及致贫风险,针对扶贫移民适应期生计发展扶持政策实施过程中存在的“政策对接有落差、政策衔接有缝隙、政策承接有障碍”等资源承接问题,尝试提出提高移民发展可行能力、注重产业发展、整合发展扶持政策与资源、强化移民专业经济组织建设、健全农村要素市场、促进发展要素整合联动等建议,以促进扶贫移民安稳致富奔小康。     

Expanded renal transplantation: a competing risk model approach

Multi-state models (MSMs) are useful to analyze survival data when, besides the event of main interest, one or more intermediate states of the individual are identified. These models take the several existing states and the possible transitions among them into account. At the same time, covariate effects on each transition intensity may be investigated separately and, therefore, MSMs are more flexible than the standard Cox proportional hazards model. In this work, we use MSMs to investigate the impact of the quality of a transplanted kidney for a group of patients at the Hospital Universitario Central de Asturias. Specifically, we use an illness-death model to study the evolution of patients with kidney disease who received a renal transplant after a dialysis period. The intermediate state is defined as the failure of the received organ, while the terminating state is the death of the patient. In order to increase the potential number of organs available for transplant, the standards of quality for the transplanted kidneys were relaxed (the new criteria are labeled expanded criteria), and these ‘expanded kidneys’ were transplanted in appropriate candidates (older patients, with higher prevalence of diabetes mellitus). Results suggest that the expanded kidneys have a minor effect on survival, while both the kidney mortality and the risk of death increase with the patient's age and the serum creatinine and serum hemoglobin levels.     

Computation of Sharp Bounds on the Expected Value of a Supermodular Function of Risks with Given Marginals

We show that the rearrangement algorithm (RA) introduced in Puccetti and Rüschendorf (2012 Puccetti, G., Rüschendorf, L. (2012). Computation of sharp bounds on the distribution of a function of dependent risks. Journal of Computational and Applied Mathematics 236(7):1833–1840.[Crossref], [Web of Science ®] , [Google Scholar]) to compute distributional bounds can be used also to compute sharp lower and upper bounds on the expected value of a supermodular function of d random variables having fixed marginal distributions. Compared to the analytical methods existing in the literature the algorithm is widely applicable, more easily obtained and gives insight into the dependence structures attaining the bounds.
