商业银行中间业务的合作与竞争研究

近年来，大力发展中间业务成为国内商业银行的共识。合作与竞争应该是商业银行中间业务共同发展、谋求内外部效率最优的发展模式。国内商业银行需要从排他性竞争走向合作竞争，建立全新的合作竞争的共赢关系。本文引入合作竞争的理论，运用厂商理论、资源依赖性观点、博弈论和交易成本学的观点来分析国内商业银行在中间业务上竞争合作的动因，提出通过竞争合作促进国内商业银行中间业务发展的具体策略，并对在构建共赢关系过程中应注意的问题进行了深入探讨，就WTO后国内银行如何实施更为有效的中间业务发展战略提出了方案建议。     

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.     

Knowledge Disclosure and Transmission in Buyer–Supplier Relationships

A buyer’s technical knowledge may increase the efficiency of its supplier. Suppliers, however, frequently maintain relationships with additional buyers. Knowledge disclosure then bears the risk of benefiting one’s own rival due to opportunistic knowledge transmission through the common supplier. We show that in one-shot relationships no knowledge disclosure takes place because the supplier has an incentive to transmit and, anticipating that, buyers refuse to disclose any of their knowledge. In repeated relationships knowledge disclosure is stabilized by larger technological proximity between buyers and suppliers and destabilized by the absolute value of the knowledge.      

论商标禁用权范围的判定

商标权包括专有使用权和禁用权两方面的内容。混淆理论是划定商标禁用权范围的理论基础。基于混淆理论,商标禁用权在商标权域外也具有一定的排他效力,主要表现在商标权的禁用权扩张,延伸至商号、域名、商品名称或者商品装潢等领域。     

论预约定价的民法适用

预约定价作为税法开拓的新领域,尽管起步较晚,但发展却异常迅速。与预约定价实践迅速发展形成鲜明对比的是预约定价的理论研究却异常缓慢,在中国如此,在世界亦如此。通过对预约定价的概念进行界定,建议运用法学多学科的视角对预约定价进行理论分析,并大胆把民法、行政法和公共管理的相关理论援引到预约定价中,来分析预约定价的民法适用问题。     

Acceptability and Ethics of Product Placement in Sport Video Games

Product placement in sport video games is an emerging area of marketing and advertising communication, but it also raises controversial ethical issues. In order to investigate these issues from a consumer perspective, this study examines the perceptions of the acceptability of product placement in sport video games (SVGs). Data were gathered from 253 sport video gamers using an online survey. The results indicate that while sport video gamers generally have favorable attitudes toward product placement in sport video games, ethically-charged products such as alcohol, cigarettes, and guns are perceived as less acceptable than other products. Individual differences among sport video gamers are found based on their related attitudes, hours of playing sport video games, and gender. Also, sport video gamers who have favorable attitudes toward product placement, in general, are more likely to intend to purchase a product or brand which may be placed in sport video games.     

原型范畴理论视角下的英语时态认知解读

原型范畴理论作为认知语言学概念的基础近年来逐渐得到了语言学家的重视。原型范畴理论可以用于英语教学并对英语时态具有一定的解释力,从而为英语时态教学开辟新视角。本文以一般现在时态、一般过去时态、一般将来时态为例,探索原型范畴理论在英语时态教学中的应用。希望能推动该理论在英语时态教学中的应用。

市场分割的制度基础与概念内涵——基于组织社会学制度理论的视角

中国的市场分割是中国经济转型在特定阶段出现的一种市场结构或状态。从组织社会学制度理论的视角看中国市场分割可以发现:中国的市场分割存在着行为权力的分割现象,市场分割不仅源于制度和政策的差异,同时也有制度与政策执行中的差异。市场分割中的地区性行政垄断、地方保护主义行为及非整合状态,反映出现阶段的中国经济体制中存在的问题。
