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.     

The Stock Price-Volume Linkage on the Toronto Stock Exchange: Before and After Automation

This paper investigates the information content of trading volume on the Toronto Stock Exchange before and after the move towards fully electronic trading. It is argued that if price discovery improves under electronic trading, the predictive power of volume should be less significant. The empirical analysis supports more accurate price discovery under electronic trading. Results from both the structural and vector autoregression models indicate that the predictive power of volume for price variability disappears after full automation.     

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.

县乡财政:困境与出路

近年来,我国的财政收入以年均20%的速度增长。但在财政收入总量增长的同时,基层财力不足问题严重。主要表现为县乡财政困难和庞大的债务问题。据不完全统计,目前我国县乡政府的债务总规模在4000亿元到1万亿元之间。县乡财政困难不仅严重影响基层经济的发展和公共物品的提供,同时也制约了我国社会整体发展水平的提高,更不利于全面建设小康社会。解决县乡财政困难问题已刻不容缓。本文在考察了县乡财政困难具体情况的基础上,从我国现行财税体制、经济和社会因素等方面进行了多角度的原因分析,力图为县乡财政解困提出一些切实可行的政策建议。     

基尼系数与企业内部薪酬分配合理性研究

本文试图把基尼系数从宏观引向微观，探讨用基尼系数来反映企业内部收入分配的合理性问题。论文先从理论上分析了企业内部影响基尼系数的因素，企业分配政策对基尼系数的影响：然后根据实际数据对三个组织的内部收入分配的基尼系数进行计算，证明了在企业应用基尼系数的可行性：最后得出结论：目前社会上存在的不公平，并不是工资差别引起的，而是由灰色收入、城乡差别、行业差别等其他因素引起的。     

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.
