金融危机后的俄罗斯银行业结构变迁与绩效改善

本文分析了俄罗斯银行体系的改革及银行业的重构，1998年金融危机后俄罗斯银行业的变化以及2004年“银行信任危机”及其深远意义。至于的银行体制改革和制度建设未来将走向何方？笔者认为，俄罗斯将进一步完善二级银行体制，一方面加强中央银行和政府（财政部）两个宏观调控主体的协调；另一方面加强中央银行的调节和监督职能。     

What drives the choice of the type of partner in R&D cooperation? Evidence for Spanish manufactures and services

We analyse the heterogeneity in firms’ decisions to engage in R&D cooperation, taking into account the type of partner (competitors, suppliers or customers, and research institutions) and the sector to which the firm belongs (manufactures or services). We use information from the Technological Innovation Panel (PITEC) for Spanish firms and estimate multivariate probit models corrected for endogeneity which explicitly consider the interrelations between the different R&D cooperation strategies. We find that placing a higher importance to publicly available information (incoming spillovers), receiving public funding and firm size increase the probability of cooperation with all kind of partners but the role is much stronger in the case of cooperative agreements with research institutions and universities. Our results also suggest that R&D intensity and the importance attributed to the lack of qualified personnel as a factor hampering innovation are key factors influencing positively R&D cooperation activities in the service sector but not in manufactures.     

New development: The conceptual underpinnings of international public sector accounting

The conceptual underpinnings of accounting standards are potentially very important for the future of public sector accounting internationally. The authors explain why and comment on the implications for public sector accounting.     

不良贷款约束下的中国银行业效率——基于方向性距离函数的实证分析

运用方向性距离函数方法测度中国银行业2000～2006年包含不良贷款的技术效率及规模效率得出,在平均意义上,考虑不良贷款后,国有和股份制银行在生产前沿上的数目增多,中国银行业的效率水平提高并且效率值变化近似于V字型;在最大化减少不良贷款和投入同时增加好产出时得到的效率值较高;中国银行业处于规模报酬递减区域,但从长远看,规模效率有上升的趋势。     

The Subprime Panic*

Understanding the ongoing credit crisis or panic requires understanding the designs of a number of interlinked securities, special purpose vehicles, and derivatives, all related to subprime mortgages. I describe the relevant securities, derivatives, and vehicles to show: (1) how the chain of interlinked securities was sensitive to house prices; (2) how asymmetric information was created via complexity; (3) how the risk was spread in an opaque way; and (4) how trade in the ABX indices (linked to subprime bonds) allowed information to be aggregated and revealed. These details are at the heart of the origin of the Panic of 2007. The events of the panic are described.     

How supply chain oriented is the port sector?

The current literature recognizes the relevance of supply chain orientation for ports and terminals. However, there is very little empirical study on the issue, particularly in relation to whether in fact ports are supply chain oriented. This paper contributes to the empirical literature by considering the port of Incheon as a case in point and by measuring the degree of its supply chain orientation based on certain valid indicators drawn from the current literature. Further, unlike the previous empirical literature, this paper examines both operator and user perspectives. The findings of this study have significant strategic policy implications and shed more light on the role of supply chain orientation in practice.     

Mixed Market Competition in a Quality Differentiated Duopoly Model An Approach to Banking Sector

This paper attempts to develop a theoretical framework to investigate the competitive implications of quality choices of financial institutions whereby they charge prices to consumers based on their willingness to pay for the service qualities in the mixed market scenario under vertical product differentiation model. Initially, it analyzes benchmark equilibrium solutions of monopoly and duopoly to establish the degree of quality differentiation between two private banks in an uncover market configuration. Further, it estimates the quality differentiation between private and public banks, and examines the interaction between two market structures keeping public bank as both leader and follower, and then measures the social welfare from different prospectives. The explicit operation of two stages Nash equilibrium game forecasted that public banks＇ monopoly seems to be still better than a private banking, and it is socially optimal. The outcome demonstrates a significant importance of vertical quality differentiation for policy implication in banking industry and provides an insight on the reasons of particular co-existence of public and private banking services in the specified location. In this context, it is concluded that the presence of public banks in banking industries is a crucial condition for obtaining the higher range of social welfare.     

Empirical of the Taiwan stock index option price forecasting model – applied artificial neural network

This work presents a novel neural network model for forecasting option prices using past volatilities and other options market factors. Out of different approaches to estimating volatility in the option pricing model, this study uses backpropagation neural network to forecast prices for Taiwanese stock index options. The ability to develop accurate forecasts of grey prediction volatility enables practitioners to establish an appropriate hedging strategy at in-the-money option.     

货币危机与银行危机共生因子实证分析——国别比较的视角

共生危机的事实表明,货币危机与银行危机共生的现象在不同类型的国家均可能出现,而非某一类国家所特有的现象.基于对共生性货币银行危机触发机制国别差异的考察,文章在对1980～2006年间60个国家共生危机发生情况识别的基础上,分别构建了工业化国家和发展中国家共生危机生成的逐步Logistic回归模型.研究表明,工业化国家的共生危机主要是经济中各类矛盾累积的结果,发展中国家则主要源于本国制度缺陷,而采用滞后一期的变量来解释工业化国家共生危机时,效果不显著.
