Insurance with Frequency Trading: A Dynamic Analysis of Efficient Insurance Markets

This paper extends existing insurance results on the type of insurance contracts needed for insurance market efficiency to a dynamic setting. It introduces continuously open markets that allow for more efficient asset allocation. It also estimates the role of preferences and endowments in the classification of risks, which is done primarily in terms of the actuarial properties of the underlying risk process. The paper further extends insurability to include correlated and catastrophic events. Under these very general conditions the paper defines a condition that determines whether a small number of standard insurance contracts (together with aggregate assets) suffice to complete markets or one needs to introduce such assets as mutual insurance.

中小非上市公司信用风险的评价研究——基于WEB与FAHP的视角

信用是人类社会最古老的词汇之一,而信用风险的管控是现代社会经济生活关注的核心问题之一。中小企业既是资本主义社会也是社会主义社会向前发展的源驱动力,中小企业的发展离不开现代信用体系的支撑。在文章中,中小企业按其信息的披露程度分为上市公司与非上市公司,相对于中小企业上市公司来说,由于交易的参与人信息不对称,中小非上市公司信用风险评估是交易双方以及各类金融机构最关心和最难解决的难题之一。在现代信息网络技术普遍化的背景下,利用人工以及机器搜索策略,充分挖掘中小非上市公司信息风险元和分类整理,并在此基础之上进行模糊综合评估,最后通过算例说明基于WEB对中小非上市公司信用风险的模糊综合评价的方法行之有效。     

Industry risk transmission channels and the spillover effects of specific determinants in China’s stock market: A spatial econometrics approach

This paper uses a spatial econometrics approach to study the industry risks in China’s stock market. We comprehensively consider the real linkage and information risk transmission channels and analyze the risk spillovers of specific determinants. Our empirical results show the following: 1) The real linkage channel and information channel are both effective transmission channels for driving spillover effects, and the information channel is of the utmost importance. 2) The spillover effects of specific determinants exist and are persistent. The superposition of spillover effects may lead to extreme risk. 3) The transmission channels and spillover effects are asymmetric in different regimes.     

Skill transferability,regret and mobility

After graduation many students start working in sectors not related to their field of study or participate in training targeted at work in other sectors. In this article, we look at mobility immediately after graduation from the perspective that educational choices have been made when these pupils had little experience of the actual working life in these professions. We develop a model where students accumulate partially transferable human capital but also learn about their professional preferences at the university and during the first years in the labour market. As a consequence of this newly acquired insight, these young workers might realize that working in another occupational field would better fit their preferences, although they are better equipped to work in their own field. The empirical analysis reveals that if wages are 1% lower due to lower skill transferability, the probability that a graduate who regrets his choice actually switches decreases by 1.4 percentage points, while those who switch on average take 0.3 months additional education.     

基于风景健康的海南省自贸区人居环境 空间研究

海南经过30年的经济特区建设已正式迈入自贸区建设的新时代，所面临的地区发展与生态维育矛盾逐步加剧。为保育海南优良的生态品质，提升海南人居环境空间质量，基于“健康、生态、人居”三元耦合与互动多赢的发展关系，提出与之适宜的风景园林健康理论；结合前人经验，以人居环境空间规划为切入点，解析人居环境空间研究内容。运用ArcGIS 10.2.2空间分析和Fragstats 4.2景观格局分析，解析海南省域三生空间敏感性、资源利用效率可持续性，以及资源服务范围与开发建设空间适宜性，结合人居环境空间发展特征，提出从全岛国土空间、资源统筹和空间营造3个方面进行规划引导，并提出以下观点：1)人类活动对资源环境和空间利用的合理性是有效保障海南人居环境空间的前提基础；2)遵循风景园林健康理论指导的全域国土空间规划、资源统筹规划和空间营造规划是提升海南人居环境空间的根本路径；3)“健康、生态、人居”三元耦合和互动多赢的关系均衡与协调是提升海南人居环境空间的终极目标。     

Impact of remittances on household health care expenditure: Evidence from the Nepal Living Standards Survey

This paper examines the effect of remittance inflows on health care expenditure in Nepal using the Nepal Living Standards Survey 2010–2011. Using the recursive three‐stage least square regression method, the propensity score matching method, and the Oaxaca–Blinder decomposition method, we find a positive and significant effect of remittances on health care expenditure. In particular, our analysis shows a 0.099% increase in health care expenditure for every 1% increase in overall remittances. This effect increases to 0.189% for earned remittances (remittances received from a household member). We also find that remittance‐receiving households with at least one migrant family member have different health care spending behavior than those with no migrant members.     

降低电网企业垄断程度的改革策略分析

电网一般认为是自然垄断经营的.降低电网垄断经营的主要手段之一是输配分开.输配分开是我国电力体制改革存在争议的热点问题,具有较高的改革成本和风险.分析了自然垄断行业的模拟竞争,提出模拟竞争是在自然垄断行业引入竞争的主要方式;通过总结分析国外改革情况,提出输配分开并不是电力改革的必然选择;全面分析了输配分开的改革成本和改革风险,如输配电界限的动态变化、降低电网经营的规模效益等,指出了输配分开的改革成本和改革风险;最后分析了输配分开的期望效益.

房地产信托投资非预期风险评价方法及应用研究

房地产信托投资所具有的投资大、周期长、项目质量要求高、同业竞争激烈、流动性较弱等特征,决定了其面临的风险更多地表现为非预期性。本文从行业、项目、开发商、信托公司等方面分析了房地产信托投资非预期风险的成因,并归纳了非预期风险因素的构成因子,根据多级模糊综合评价原理,以某房地产信托投资业务为研究对象,在充分调研和对数据资料实施规范化处理的基础上,构建了非预期风险评价模型,对各类非预期风险因素进行了三级模糊综合评价,识别了各非预期风险因素的重要性程度,为房地产信托投资机构评价、监测、控制房地产信托投资业务的非预期风险提供了重要的信息支持。     

The effects of health aid on child health promotion in developing countries: cross-country evidence

Although epidemiological knowledge in relation to child health has improved in the last few decades, around 3 million children die each year in developing countries from preventable diseases. The international development community views increased immunization coverage for children as an important step in eliminating or reducing these deaths. Many developing countries have very limited resources to tackle major health problems and have to rely on external finance. This article examines the impact of foreign aid devoted to the health sector on child health promotion in developing countries. Two proxies for child health promotion are used: (a) immunization against measles and (b) immunization against Diphtheria–Pertussis–Tetanus (DPT). A range of model specifications and panel data econometric techniques are applied to data covering the period 1990 to 2005. This article finds a positive and statistically significant link between health aid and the measures of child health promotion.
