MONETARY VALUATION OF INSURANCE AGAINST FLOOD RISK UNDER CLIMATE CHANGE*

Climate change is projected to increase the risk of natural disasters, such as floods and storms, in certain regions. This is likely to raise the demand for natural disaster insurance. We present a stated preference survey using choice modeling with mixed logit estimation methods in order to examine the effects of climate change and the availability of government compensation on the demand for flood insurance by Dutch homeowners. Currently, no private insurance against flood damage is offered in the Netherlands. The results indicate that there are opportunities for the development of a flood insurance market.     

我国区位优势对制造业集聚影响的实证研究

对我国29个省(自治区、直辖市)的区位优势和20个制造业细分行业的集聚水平进行了测算,采用系统广义矩估计方法实证分析了区位优势对制造业集聚的影响。结果表明:区位优势与制造业各行业的集聚程度显著相关:大多数现代制造业和依赖规模经济的制造业与区位优势正相关,大部分传统制造业与区位优势负相关;不同的制造业细分行业侧重不同方面的区位优势。     

A machine-learning method for improving crash injury severity analysis: a case study of work zone crashes in Cairo,Egypt

Abstract

The quality of vehicular collision data is crucial for studying the relationship between injury severity and collision factors. Misclassified injury severity data in the crash dataset, however, may cause inaccurate parameter estimates and consequently lead to biased conclusions and poorly designed countermeasures. This is particularly true for imbalanced data where the number of samples in one class far outnumber the other. To improve the classification performance of the injury severity, the paper presents a robust noise filtering technique to deal with the mislabels in the imbalanced crash dataset using the advanced machine learning algorithms. We examine the state-of-the-art filtering algorithms, including Iterative Noise Filtering based on the Fusion of Classifiers (INFFC), Iterative Partitioning Filter (IPF), and Saturation Filter (SatF). In the case study of Cairo (Egypt), the empirical results show that: (1) the mislabels in crash data significantly influence the injury severity predictions, and (2) the proposed M-IPF filter outperforms its counterparts in terms of the effectiveness and efficiency in eliminating the mislabels in crash data. The test results demonstrate the efficacy of the M-IPF in handling the data noise and mitigating the impacts thereof.     

论股东代表诉讼之判决既判力主观范围的扩张

股东代表诉讼判决既判力主观范围的扩张，包括向公司与其他股东二者的扩张。长期以来原告股东与公司的关系存在诉讼代理与诉讼担当之争，综合立法现状、制度渊源与改革成本等因素的考量，原告股东与公司的关系应定性为法定诉讼担当，从而为判决既判力向公司扩张提供正当理论支撑。但受制于股东代表诉讼前置程序形骸化，对原告股东起诉的正当性审查无从实现，公司与其他股东对于诉讼的获悉存在信息壁垒，由此应当通过诉讼告知程序为公司或其他股东作为有独立请求权第三人进入诉讼开辟通路。同时借由不起诉理由书与统一案件受理费等程序构建，作为其他股东进入诉讼的激励机制，进而为既判力的扩张提供有理性基础。     

辅助睢生金融机构发展与中小企业融资改善:台湾地区的经验与借鉴

我国台湾地区通过发展中小企业信用保证基金、农业信用保证基金、华侨贷款信用保证基金等辅?性金融机构,对改善中小企业融资发挥了较好的作用.中国大陆中小企业信用担保体系目前还存在着机构规模小、资金实力不足、相关制度缺位等不足之处.可借鉴台湾地区辅助性金融机构的经验,由国家财政和金融机构捐资,根据不同类型的中小企业设立全国性的专项担保基金,分别为不同类型的中小企业贷款提供信用保证.     

大数据驱动情景下企业商业模式创新的发生机理

大数据时代是当前企业面对的全新运营环境,同时,企业商业模式创新一直是学术和实务界的关注热点,但大数据驱动情景下企业商业模式创新的发生机理至今仍是一个未解“黑箱”。采用话语分析方法,基于100个大数据案例提炼了商业模式创新的发生机理。研究得到了集合数据、行为、属性和情景4个范畴共16个语素的驱动因子模型,并刻画了以上语素和范畴之间的关系路径。

通货膨胀影响工业经济运行效率吗?——基于中国工业数据的VAR分析

利用1957年～2010年中国工业经济数据,运用基于VAR的计量分析方法 ,研究中国工业经济运行效率与通货膨胀的关系。结果表明通货膨胀是中国工业经济运行效率的格兰杰原因,从脉冲响应上来看,通货膨胀对中国工业经济运行效率的负面影响主要在短期,从中长期来看适度的通货膨胀有助于中国工业经济运行效率的提升,但我们必须规避高通胀,从方差分解上来看,通货膨胀对中国工业经济运行效率的贡献约为8%,说明制约中国工业经济运行效率提升的根本性因素在于工业经济自身,而不是通货膨胀,因此转变工业发展模式,提升工业发展效率成为当前中国工业经济的重中之重。     

The case of market and system failures in services innovation

This paper reviews and analyses the rationale for an innovation policy in services. It focuses on the relevance of the various categories of market and system failures, on the basis of economic arguments and some empirical evidence at EU level. Results show that market and system failures affect service innovation, so that there are no economic reasons supporting any discrimination of policy actions against service activities. Moreover, some of the market and system failures may be even more relevant in the field of services than of goods, although differences between categories of services should be also taken into consideration.
