西三角经济圈发展中政府间合作的困境及其消解

基于区域经济一体化的"西三角"经济圈的成立有利于西部大开发的深入。但是借鉴已有的合作经验与教训,西三角经济圈内各政府的合作存在一些必须消除的困境,需要从组织机构形式、制度保障、多元化合作主体参与等方面采取措施来解决。     

基于ObjectARX的露天矿三维建模技术与可视化研究

本文提出了一种建立带有约束条件的Delaunay三角网方法,即集成了矿山中的散点数据和线状数据,使模型更接近实际,精度更高,完成建立露天矿的三维模型。本论文以魏家峁露天煤矿为应用实例,对三维可视化系统的部分功能进行了开发,包括现状图数据处理、带有约束条件Delaunay三角网的建立、边界处理以及采场三维模型的建立等功能。该系统是以AutoCAD为开发平台,以面向对象的编程语言ObjectARX对平台进行二次开发。系统在魏家峁露天煤矿得到了较好的应用,表明系统具有实用性强、易于操作、模型可靠等特点。     

基于整体性治理的新型农村公共服务体系研究——以“服务三角”模型为分析框架

公共治理的碎片化和分散化是导致城乡及区域之间教育、医疗、社会保障、基础设施以及劳动就业等基本公共服务非均等化的根本原因。借鉴整体性治理理论,构建以＂服务三角＂为宏观旨趣的新型农村公共服务体系的操作策略是：按照农民需求强弱分类提供公共服务,实行政府主导、市场运作和社会协同的服务政策,建立＂市、县、乡（镇）、村＂一体化服务网络,营造＂跨界合作＂的公共服务组织文化。     

测试条件对测定橡胶相对体积磨耗量的影响

采用在不同磨损行程和不同试样伸出长度的情况下测定了橡胶试样的相对体积磨耗量;并在标准环境温度条件下,在不同相对湿度的情况下测定橡胶试样的相对体积磨耗量。根据实验结果,分析了测试条件对橡胶试样相对体积磨耗量试验结果的影响。     

Valuing Loss Firms: What Can Be Learned From Analysts' Forecasts?

Prior research documents an anomalous negative price–earnings relation when a simple earnings capitalization model is estimated for loss‐making firms. Collins et al. (1999 ) suggest that the model is misspecified due to the omission of book value of equity. However, results from previous studies are confusing. We try to enrich prior literature by focusing on analysts' forecasts. In particular, we assess the role of earnings and book value in valuing loss firms using several measures based on the information provided by analysts. We hypothesize that the role of accounting figures depends on whether the loss firm is supported or not by investors. According to this argument, we construct several measures of investor support based on analysts' forecasts, and then test the value relevance of accounting information depending on the degree of support. Our results confirm the usefulness of the notion of ‘investor support’. For those loss firms that are expected to liquidate, we find that the inclusion of book value of equity in the model removes the negative sign on the earnings coefficient. However, for those loss firms that are expected to reverse current losses, we find that the coefficient on earnings remains negative despite the inclusion of book value.     

Endowment effect theory,prediction bias and publicly provided goods: an experimental study

Many studies report on a systematic disparity between the willingness to pay for a certain good (WTP) and the willingness to accept retribution payments in exchange for giving up this good (WTA). Thaler [Thaler RH (1980) J Econ Behav Organ 1:39–60] employs prospect theory to explain this disparity. The literature contains two different interpretations of his endowment effect theory. Accordingly, the disparity is caused either by the disutility from parting with one’s endowment and/or by an extra utility from ownership which is not anticipated by individuals who are not endowed with the good. So far, the empirical evidence on the applicability of endowment effect theory is limited to private goods. This paper reports on an experiment which finds a significant ownership utility effect for a publicly provided good. This result indicates that prospect theory applies to publicly provided goods even though consumers do not have exclusive property rights.      

衍生品市场风险案例总结评析

我国将推出衍生品市场的重要品种股指期货。为借鉴历史,促进我国衍生品市场的稳健发展,对曾爆发的衍生品交易亏损事件、与衍生品有关的金融危机总结,指出衍生品具有的高风险性、杠杆性、虚拟性、国际性等特征决定了衍生品市场本身潜藏的风险;亏损事件体现了对衍生品的不当使用;金融危机与国际投机者的攻击、危机发生国自身的经济金融安排有关;衍生品市场不是这些事件、危机的根本原因,必须辩证看待,予以科学管理和合理利用。     

基于损失分布的产险公司保险保障基金构成机制研究

保险保障基金制度是为了确保保单持有人利益和完善保险企业退出机制而建立的特殊制度。保险保障基金的筹集是保险保障基金制度的核心内容，它直接关系到保险保障基金制度的有效运行。本文以产险公司为例，通过拟合损失分布，从保单定价的盈亏平衡原理和产险公司实际偿付能力出发，给出了产险公司破产时，保险保障基金的期望损失计算公式，并提出相关参数的估计方法，对建立保险保障基金的风险缴纳比例机制有一定的借鉴意义。     

居民金融素养与家庭诈骗损失

本文基于中国家庭金融调查(CHFS)的数据,采用工具变量法,从微观层面研究了居民金融素养对家庭遭遇诈骗产生损失概率的影响。研究发现:(1)居民金融素养水平的提高可以显著降低家庭因诈骗产生损失的可能性,即家庭具备的金融素养越多,越不会在诈骗中受损。(2)家庭收入在居民金融素养和家庭诈骗受损概率关系中起显著负向调节作用,当家庭收入越高时,其在诈骗中遭受损失的可能性受居民金融素养水平的影响越小。进一步的异质性研究表明,金融素养对不同教育水平家庭诈骗受损概率都具有显著的负向影响,但是影响效果存在差异。
