国内中小企业发展支持体系研究述评

中小企业是国民经济中一支活跃的力量.根据政府政策的变迁,本文将中小企业发展的政策和服务体系的国内研究划分为四个阶段.以政策时期为线索,本文回顾了关于中小企业发展的政策和服务支持体系的研究文献.其中,政策支持体系包括产业、法律、财税和国际化支持四个方面;服务支持体系包括金融、信息咨询和技术服务三个方面.     

脆弱性分析和制图系统在中国扶贫项目的应用

介绍了联合国世界粮食计划署在选择粮食援助项目受援地区和人群时,采用的脆弱性分析和制图系统（Vulnerability Analysis and Mapping）及其在中国扶贫项目区选择中的应用,特别是在确定了项目县后,通过脆弱性分析,进一步进行了项目乡镇的选择,对于提高扶贫资源的效率、扶助最需要帮助的人群起到了重要的作用。     

发展山西现代农业的财政政策浅探

发展现代农业是社会主义新农村建设的首要任务,是以科学发展观统领农村工作的必然要求.近年来,山西省农业发展情况反映出由传统农业向现代农业演进的特点,但在此过程中仍存在着基础设施建设落后、农业生产科技水平低、社会化服务体系薄弱、农业产业化程度不高等问题.针对这些问题,应给予财政支持,促进传统农业向现代农业的转变.

本文从实证的角度出发,以大陆上海地区、江苏地区以及台湾地区的企业为研究对象,收集244份有效样本,以LISREL结构方程式为分析工具,企图建立企业文化、企业培训与组织绩效等构面完整的理论模型,并运用大量数据进行统计分析,以解释高阶主管支持、企业文化强度对企业培训、组织绩效的影响。     

论虚拟仿真技术与群体支持系统在工程管理中联合应用

工程施工计划是一项复杂的工作，不断增长的复杂因素决定了工程管理人员需要采取新的、从未被用过、检测过的工程施工方法。缺乏便于工程策划人员进行评估和确认施工计划是否合理的工具，会在工程施工阶段造成许多重复性工作，造成成本浪费。虚拟现实技术为解决上述问题提供了一个很好的方法，会生成虚拟环境，允许项目决策人员在施工之前合理优化和选择施工方案，资源优化，降低成本，从而获得更好的投资效益。利用群体支持系统建立与工程施工计划相呼应的模型，工程数据作为其处理问题与人机交互的依据，辅助人员决策，进行项目的预算和分析，提高工程项目的价值管理。     

Are stock markets really so inefficient? The case of the “Halloween Indicator”

The old and simple investment strategy “Sell in May and Go Away” (also referred to as the “Halloween effect”) enjoys an unbroken popularity. Recent studies suggest that the Halloween effect even strengthened rather than weakened since its first publication by Bouman and Jacobsen (2002). We implement regression models as well as Hansen’s (2005) “Superior Predictive Ability” test to analyze whether stock markets are really so inefficient. In line with the predictions of market efficiency, our results reject the hypothesis that a trading strategy based on the Halloween effect significantly outperforms.     

Institutions,moral hazard and expected government support of banks

We model the expected support of banks with credit ratings from Moody's and Fitch, taking explicitly into account the capacity and willingness of governments to provide support in case of need, as well as their concerns about moral hazard (i.e., that the expected support may induce banks to assume bigger risks). Our results suggest that moral hazard concerns are relatively weak. In addition, a substantial part of the expected support can be attributed to the quality of a country's institutions. These findings have important implications for the dynamics of banking crises, the value of the ‘fair’ insurance premium banks might be called upon to pay for the expected support, as well as for ways to reduce the resulting negative externalities.     

Computing the finite-time expected discounted penalty function for a family of Lévy risk processes

Ever since the first introduction of the expected discounted penalty function (EDPF), it has been widely acknowledged that it contains information that is relevant from a risk management perspective. Expressions for the EDPF are now available for a wide range of models, in particular for a general class of Lévy risk processes. Yet, in order to capitalize on this potential for applications, these expressions must be computationally tractable enough as to allow for the evaluation of associated risk measures such as Value at Risk (VaR) or Conditional Value at Risk (CVaR). Most of the models studied so far offer few interesting examples for which computation of the associated EDPF can be carried out to the last instances where evaluation of risk measures is possible. Another drawback of existing examples is that the expressions are available for an infinite-time horizon EDPF only. Yet, realistic applications would require the computation of an EDPF over a finite-time horizon. In this paper we address these two issues by studying examples of risk processes for which numerical evaluation of the EDPF can be readily implemented. These examples are based on the recently introduced meromorphic processes, including the beta and theta families of Lévy processes, whose construction is tailor-made for computational ease. We provide expressions for the EDPF associated with these processes and we discuss in detail how a finite-time horizon EDPF can be computed for these families. We also provide numerical examples for different choices of parameters in order to illustrate how ruin-based risk measures can be computed for these families of Lévy risk processes.
