Information Content of Earnings and Earnings Components of Commercial Banks: Impact of SFAS No. 115

SFAS No. 115 modified classification of debt and equity securities held by firms and also modified the reporting format for unrealised gains/losses on security transactions (URGL). This study investigates whether implementation of SFAS No. 115 improved information content of earnings and earnings components of commercial banks. Improvement in the information content is measured by comparing the association between equity returns and earnings and earnings components of the post-adoption period of SFAS No. 115 with the pre-adoption period.The test results indicate that the association of equity returns with earnings components and aggregate earnings is significantly stronger in the post-adoption period compared to the pre-adoption period. The improvement is especially evident for the components of URGL and non-interest revenues. These results suggest that information provided by earnings components is considered more value relevant for investment decision after implementation of SFAS No. 115. Findings on non-interest revenues indicate that revenues from banking activities other than lending also play an important role in the commercial banks' profitability.     

Aging and Retirement: Evidence Across Countries

How do demographic factors influence retirement? Using a large cross-country data set, I show that in countries with a larger share of elderly in their population the length of retirement is longer. This result holds true if I control for wealth effects, and when the effective labor force participation rate of the elderly is used instead of the official retirement age. Retirement policies and the social security size are strictly related: a new variable, representing the aggregate relevance of retirement policies, turns out to be significant in explaining the size of social security. Finally, the total amount of social security transfers is positively related with the increase of the elderly population, while in per capita terms this relation is not significant.

Dynamic volatility and external security related shocks: The case of the Athens Stock Exchange

This paper analyses the impact of exogenous national security related shocks on the time-varying volatility structure of the Greek stock market. Alternative autoregressive conditional heteroscedastic models are estimated, in order to identify the best fit that adequately describes return volatility behavior, testing symmetric as well as asymmetric innovation responses. An external national security related shock factor is included as well as a military crisis dummy, in order to depict possible implications for the conditional variance. The empirical findings appear to support a statistically significant impact of both national security related factors on the Athens stock market returns.

论中国的石油安全问题

目前，石油问题引起了业内各界人士的普遍关注，关于石油战略储备的话题沸沸扬扬。中国石油能源面临的主要问题，并不是世界石油资源的短缺或长期供应能力不足；也不是由于政治、军事冲突而对我国可能实行的石油禁运，中国石油能源面临的最大问题是中东地区突发事件引起的国际油价波动，以及其他国家间的重大冲突造成短期石油供应受阻而波及中国。我国的当务之急是尽快建立石油战略储备体系，而且应根据我国的生产和消费状况确定合理的储备规模和储备方式。     

An integrated system for information security management with the unified framework

Information security management plays an essential role for drawing the roadmap of information security; thus, many theoretical methodologies and practical standards are brought into this domain. However, many standards and methodologies are too cumbersome to be adopted by an organization. Additionally, there is no unified framework to systematically handle the tedious tasks of information security management. This study’s primary goal is to design an integrated system for information security management (ISISM) that aims to use current methodologies and standards to solve the above-mentioned issues. Because business impact analysis and risk analysis are the most important areas within this domain, we carefully select the related methods and then integrate them into a unified framework, upon which the proposed ISISM depends. To achieve this outcome for this study, security requirement engineering is adopted, which enables the designed system to support system users in generating risk assessment reports with related information security policies.
