中国会计准则国际协调效果的实证研究

自改革开放以来,我国进行了一系列旨在加强会计准则国际协调的改革,会计信息编报者和使用评价者都十分关心会计准则国际协调的效果。本文在借鉴国内外相关研究的基础上,采用实证研究方法从纵向上比较和分析AB股公司的净利润差异与会计信息价值相关性的变化,以期对我国会计准则国际协调的总体效果做出经验性评价。     

基于精算方法的信用风险的量化

比较了保险风险和信贷风险的基本特征后可以发现，精算模型的方法和思路可以用来描述商业银行的信用风险。可以通过定性分析和定量分析相结合的方式，推导出适用的信用风险量化管理模型。在数据整理和检验的基础上，借鉴寿险精算的生命模型思想可以建立“正常-损失”模型，进而实现对贷款损失率的解释；借鉴非寿险准备金测算的方法，可以采用链梯法测算商业银行短期贷款业务应提取的贷款坏账准备金数额。在上述方法的基础上，可以将“正常-损失”模型与链梯法结合起来，测算长期贷款的坏账准备金。

Evaluating a method of integrating generic skills with accounting content based on a functional theory of meaning

This paper documents and evaluates an intervention designed to integrate the learning of selected generic skills, particularly analytical thinking and written communication skills, with the learning of accounting content. The method used was to scaffold practice in analytical thinking skills through specially designed writing activities. Content‐focused learning materials adapted from task‐types currently used to teach language skills were used to facilitate the analysis and interrelation of accounting concepts, principles and problems in interpersonal communicative contexts typical of actual accounting practice. The materials, in three assignments, were designed to incorporate: (i) selected generic skills, taken from those listed by the professional accounting bodies; (ii) writing, both as communication and as an instrument for analytical thinking and learning; (iii) knowledge of accounting concepts and principles; and (iv) awareness of the interpersonal dimensions of professional communication. Overall, students showed improved learning outcomes, with improvements of 19 percentage points for non‐Australian students over the three assignments. We were also able to show significant positive relationships between the assessments of assignments 2 and 3 and performance in the knowledge‐based final examination. Improvements in the quality of learning were shown in students’ improved ability to assess their own work.     

Varying the VaR for unconditional and conditional environments

Accurate forecasting of risk is the key to successful risk management techniques. Using the largest stock index futures from 12 European bourses, this paper presents VaR measures based on their unconditional and conditional distributions for single and multi-period settings. These measures underpinned by extreme value theory are statistically robust explicitly allowing for fat-tailed densities. Conditional tail estimates accounting for volatility clustering are obtained by adjusting the unconditional extreme value procedure with GARCH filtered returns. The conditional modelling results in iid returns allowing for the use of a simple and efficient multi-period extreme value scaling law. The paper examines the properties of these distinct conditional and unconditional trading models. The paper finds that the biases inherent in unconditional single and multi-period estimates assuming normality extend to the conditional setting.     

The value relevance of top executive departures: Evidence from the Netherlands

On theoretical grounds, monitoring of top executives by the (supervisory) board is expected to be value relevant. The empirical evidence is ambiguous and we analyze three non-competing explanations for this ambiguity: (i) The positive effect on firm value of board monitoring is hidden in stock price effects due to the simultaneous occurrence of the positive real effect of monitoring and the opposing information effect. (ii) The combination of board monitoring and monitoring by other parties prevents assessing the value relevance of board monitoring in isolation. (iii) The confounding effect of a simultaneous successor appointment typically generates an upward biased estimate. Based on an analysis of price effects and trading volumes at announcement, we conclude that monitoring by the supervisory board is valued by investors: Forced departures of executive directors, also without a successor appointment, are value relevant in the Netherlands where external control mechanisms and shareholder control were virtually absent in the period studied (1991–2000).     

我国外汇储备货币组合的实证分析

截至2006年2月我国外汇储备达8536亿美元,超过日本成为世界外汇储备持有量第一大国,其后我国外汇储备也呈不断增长的态势,到2007年3月已达12020.31亿美元.外汇储备的持续增加意味着面临的风险也在持续增加.因此,如何确定合理的外汇储备币种组合成为目前需要迫切研究的课题.本文根据国内外已有研究确定了外汇储备货币结构的影响因素,结合因子分析法,得出了我国外汇储备币种组合的新选择,提出了我国外汇储备货币组合的对策建议.     

实行工程量清单招标中问题的探讨

在工程量清单招标过程中，由于施工企业对招标文件理解不足，又缺少企业内部定额，以及在管理体制和管理模式上存在着缺陷，所以制约了工程量清单报价的竞争性。在分析实行工程量清单招标中问题的基础上，提出了加强工程量清单报价的合理化建议。只有积极应对，才能适应工程量清单计价模式，增强企业竞争活力。     

地方公共服务、要素流动与要素空间配置——基于本地交易成本的均衡分析

通过"两区域、两要素与两部门"模型研究发现,即使存在区域内与区域间两类交易成本,增加公共服务仍有利于吸引要素流入,并产生要素空间聚集效应;增加公共支出以改善区内贸易条件对要素流动及其空间分布具有不同的影响;我国地方公共支出规模与全要素生产率之间存在明显的长期因果关系.     

中国宏观经济调控理论方法论研究

从经济学方法论角度看,理论的研究对象、研究内容和研究方法取决于其假设前提,本文认为生产力不平衡结构是我国宏观经济最基本的特征,也应该是进行我国宏观经济理论研究的基本假设条件。由于中西方理论基本假设的不同,本文认为我国进行宏观经济调控体系研究应该从生产力不平衡结构这一基本假设条件出发,主要采用结构分析方法进行。
