Identifying crime generators and spatially overlapping high-risk areas through a nonlinear model: A comparison between three cities of the Valencian region (Spain)

The behavior and spatial distribution of crime events can be explained through the characterization of an area in terms of its demography, socioeconomy, and built environment. In particular, recent studies on the incidence of crime in a city have focused on the identification of features of the built environment (specific places or facilities) that may increase crime risk within a certain radius. However, it is hard to identify environmental characteristics that consistently explain crime occurrence across cities and crime types. This article focuses on the assessment of the effect that certain types of places have on the incidence of property crime, robbery, and vandalism in three cities of the Valencian region (Spain): Alicante, Castellon, and Valencia. A nonlinear effects model is used to identify such places and to construct a risk map over the three cities considering the three crime types under research. The results obtained suggest that there are remarkable differences across cities and crime types in terms of the types of places associated with crime outcomes. The identification of high-risk areas allows verifying that crime is highly concentrated, and also that there is a high level of spatial overlap between the high-risk areas corresponding to different crime types.     

商业银行内部控制低效的成因及模式重构

我国商业银行金融风险的产生多是由内部控制低效造成,而内部控制低效又源于控制模式的不规范.因此,研究这一课题具有重要的理论价值和现实意义.为探索提高内部控制效果的有效途径,本文在分析我国商业银行内部控制低效成因的基础上,根据COSO报告和ERM的要求,构建了要素式动态控制的立体模式,并对这一模式的构成及其运行方式等进行了深入研究,为商业银行规范内部控制行为和降低金融风险提供了一种行之有效的管理手段.

董事会治理、高管薪酬对内部控制有效性的影响——来自沪、深两市采掘业上市公司2008～2010年经验数据

本文为研究董事会治理、高管薪酬与内部控制有效性的关系,选取2008～2010年沪深两市采掘业上市公司为样本数据,构建内部控制指数,从董事会治理和高管薪酬两个方面来考察对内部控制有效性的影响。研究发现,董事会治理和高管薪酬对内部控制有效性有一定影响。合理的董事会治理结构是企业增强竞争力和提高经营效率的必要条件,同时高管薪酬在某种程度上也影响着公司内部控制有效性的实现。

Evaluating flood risk management options in Scotland: A participant-led multi-criteria approach

The characteristics of flood risk management include complexity, large spatial scales, inter-temporal issues, plural values and conflicts of interests. It is argued that issues with such characteristics require public participation in the decision making process. This study builds on existing deliberative processes to develop a new participant-led multi-criteria method to evaluate flood risk management options in Scotland. The results show that participants preferred regeneration or planting of native woodland to other flood management options, and least preferred building flood walls and embankments. The design of the workshops allowed a rich dataset to reveal the thinking behind such results and provided a deeper understanding of why participants came to these conclusions.     

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.

The impacts of SOX and SEC investigation on the corporate governance of option backdating firms

This study investigates the combined impact of the Sarbanes-Oxley Act of 2002 (SOX) and the subsequent related Securities and Exchange Commission's (SEC) initiatives on the corporate governance characteristics of firms that had historically backdated stock options. Our results show that backdating firms had both weaker board-level and committee-level corporate governance characteristics than control firms in the pre-SOX period. In contrast, backdating firms dress up their board-level governance to meet regulatory requirements but still feature weaker committee-level corporate governance in the post-SOX era.     

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。     

Ross risk vulnerability for introductions and changes in background risk

We present two theorems that provide necessary and sufficient conditions for an expected utility maximizer to become more risk averse in the sense of Ross with respect to bearing a foreground risk after the introduction of any independent fair or unfair additive background risk. We call these decision makers Ross risk vulnerable, and show that Ross decreasing absolute risk aversion and Ross decreasing absolute prudence are jointly sufficient for Ross risk vulnerability. Restrictions on utility necessary and sufficient for Ross risk vulnerability with respect to stochastic dominance deteriorations of an existing background risk are also presented. Our analysis concludes with applications of Ross risk vulnerability.
