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.
