存贷款利差定价分析

存贷款利差合理水平取决于违约率、损失率、流动性风险、资本缓冲与信贷类资产的比率,以及无风险基准利率。银行业内部管理水平不足和存贷款市场的总体失衡会导致利差水平扩大和提高。我国当前的存贷款利差水平相对于其合理水平而言过低,不仅不利于银行业长期健康发展,而且也对整个金融体系累积了巨大的体系性风险。     

基于动态贝叶斯网络的邻近下穿隧道深基坑施工风险分析

为了减小邻近既有下穿隧道深基坑施工风险及灾害损失,科学预防施工安全事故,提出了一种基于动态贝叶斯网络（DBN）的深基坑施工风险分析模型。首先,运用BWM（best worst method）确定准则的权重;其次,基于关联规则挖掘风险因素间的相互关系,并以此构建DBN结构模型;最后,以新建厦门北站地下一层社会连廊深基坑工程为例,对提出的方法进行有效性和适用性检验。结果表明：基坑围护结构的安全度在静态被评为“较高”和“极高”的概率分别为34.6%和36.1%,且此结果随着输入风险证据发生动态变化,运用反向推理也能迅速找出围护桩渗水风险;提出的模型能明确邻近既有下穿隧道深基坑施工风险传递过程中的关键风险点,并能进行动态风险预测以及事故后致因诊断,从而实现邻近既有下穿隧道深基坑施工风险的动态管控。所提出的优化DBN模型对工前风险评估、先验分析和风险诊断有较好的适用性和较高的准确性,可为邻近既有隧道深基坑施工过程中的安全管控提供有效的决策支持,大幅提高风险控制效率。     

基于系统动力学的危险化学品运输风险因素研究

为了降低危化品运输事故频次,规避危化品在运输过程中的风险,基于系统动力学模型,从人、机、环、管4个维度构建危化品运输风险因素指标体系,使用AHP法对指标权重进行赋值,结合风险因素间的因果关系构建参数方程,利用Vensim软件仿真模拟危化品运输风险水平的变化趋势,确定单因素变量值和人、机、环、管风险子系统权重的变化对危化品运输风险系统动力学模型的影响程度。结果表明：安全意识薄弱、设备故障等风险因素的变动以及人、机、环、管风险子系统的权重变动都会影响危化品运输风险水平,人、机、环、管4个子系统对危化品运输风险的影响程度从高到低依次是人、管、环、机。研究结果可为降低危化品运输过程中的风险和制定危化品运输事故预防策略提供一定参考。     

‘RE‐OPENING THE BLACK BOX’: THE STORY OF IMPLEMENTING A RISK ANALYSIS METHOD IN A FRENCH LOCAL GOVERNMENT

This research is a study of the implementation of a risk analysis method (RAM) in a French local government. Based on the sociology of translation framework, this study shows that the success of the implementation of this management device is due to the transformation of its initial characteristics. Indeed, the RAM was initially designed to analyze the risks of outsourcing public services and thereby to aid elected officials with decision making. But in the hands of the actors in charge of its implementation, it progressively became a means for the members of the administrative services to inform elected officials about the consequences of their choices. This paper thus describes the ‘trajectory’ of this management device in a local government and, in doing so, emphasizes how it progressively became what it is (and what it is not) at present in this local government.

THE INFLUENCE OF FUNDAMENTALS ON EXCHANGE RATES: FINDINGS FROM ANALYSES OF NEWS EFFECTS

Abstract As we survey the literature of macroeconomic news in the foreign exchange market, we can by now look back on nearly 30 years of research. The first studies which analysed news effects on exchange rates were established in the early 1990s (see, for example, Dornbusch). Almost at the same time Meese and Rogoff published their influential paper, revealing the forecasting inferiority in exchange rates of structural models against the random walk. This finding has shocked the pillars of exchange rate economics and thus cast general suspicion on research focusing on fundamentals in this field. The eventual rising popularity of event studies can partly be attributed to the re‐establishment of the raison d’être of exchange rate economics. This work focuses on systematically surveying this literature with particular respect to its primary goal, i.e. shedding light on the analytical value of fundamental research. Thus, its major findings are, first, fundamental news does matter, whereas non‐fundamental news matters to a lesser degree. Second, news influences exchange rates via two separated channels, i.e. incorporating common information into prices directly or indirectly based upon order flow. Third, with a few exceptions the impact of fundamental news on exchange rates is fairly stable over time.     

Determinants of smallholder farmers' perceptions of risk in the Eastern Highlands of Ethiopia

This paper reports findings from a study of 178 farm households from two contrasting areas in the Eastern Highlands of Ethiopia. It examines risk perceptions of smallholder farmers under varying contexts. The study utilized both qualitative and quantitative methods of data collection and analysis. It was hypothesized that human capital and household characteristics and orientation, access to resources, infrastructure, information and environmental factors influence perceptions of risks in different ways. Data reduction for independent variables was done by factor analysis (principal component extraction method). Factor analyses identified factors influencing smallholder farmers' perceptions of sources of risks. Logistic regression analyses were used to study the relationships of identified principal components to perceived frequencies of occurrences and consequences of various sources of risks. Logistic regression analyses revealed that asset endowments, locational settings and livelihood diversification strategies pursued determine smallholders' perceived risks. Key findings from the informal survey point out differentiation in perceptions of causes and sources of risks by different actors.

Linking Ethics and Risk Management in Taxation: Evidence from an Exploratory Study in Ireland and the UK

Ethical dilemmas involving tax issues were identified by members of the American Institute of Certified Public Accountants as posing the most difficult ethical problem for them (Finn et al., Journal of Business Ethics 7(8), pp. 607–609, 1988). The KPMG tax shelter fraud case proves that the tax profession has not gone untainted in the age of numerous accounting and corporate scandals, such as the Enron débacle (Sikka and Hampton, Accounting Forum 29(3), 325–343, 2005). High-profile scandals serve to highlight the problems caused by differences in ethical judgement among accountants and tax practitioners and the issue of ethics has been brought publicly to the forefront of the profession. Nevertheless, the nature and dimension of ethical issues in tax practice have been largely unexplored (Erard, Journal of Public Economics 52(2), 163–197, 1993; Marshall et al., Journal of Business Ethics 17(12), 1265–1279, 1998; Frecknall Hughes, Unpublished PhD Thesis, The University of Leeds, 2002). This research aims to contribute to the debate on ethics in tax practice by reporting interview data on tax practitioners’ perceptions of ethics in the jurisdictions of Ireland and the United Kingdom and exploring the link or equation of ethics with risk management.     

Corporate Risk Management under Information Asymmetry

This paper examines the financial and operational hedging activities of US pharmaceutical and biotech firms that are subject to a high level of information asymmetry stemming from R&D investments during 2001–2006. We find evidence in support of the information asymmetry hypothesis à la Froot, Scharfstein and Stein (1993) that hedging helps mitigate the under‐investment problem. Specifically, we find that the use of financial derivatives is associated with greater firm value and that the value enhancement is larger for firms subject to greater information asymmetry and better growth opportunities. There is a synergy between financial hedging and operational hedging where the latter is used to counter product development risk. The results are robust with respect to alternative performance measures, industry‐specific growth measures, and the endogeneity problem. Our work is differentiated from existing studies that examined commodity‐based industries without addressing information asymmetry.
