"This paper investigates the lead-lag relationship in daily returns and volatilities between price movements of the FTSE/ATHEX-20 and FTSE/ATHEX Mid-40 stock index futures and the underlying cash indices in the relatively new futures market of Greece. Empirical results show that there is a bi-directional relationship between cash and futures prices. However, futures lead the cash index returns, by responding more rapidly to economic events than stock prices. This speed is much higher in the more liquid FTSE/ATHEX-20 market. Moreover, results indicate that futures volatilities spill information over to the corresponding cash market volatilities in both investigated futures markets, but volatilities in the cash markets have no effect on the volatilities of futures markets. Overall, it seems that new market information is disseminated faster in the futures market compared to the stock market. This implies that the futures markets can be used as price discovery vehicles, providing further evidence that derivatives markets contribute to completing and stabilising capital markets in Greece. A further finding of this study is that futures volume and disequilibrium effects between cash and futures prices are important variables in the explanation of volatilities in cash and futures markets."

The study explores the motives for providing voluntary accounting disclosures and investigates the financial differences between voluntary and non-voluntary disclosers. The study also examines the association between the provision of voluntary disclosures and earnings management. The findings show that voluntary disclosers exhibit higher profitability and growth and appear to be good news bearers. They also display a change in their management and a higher share trading volume. The results provide evidence that the provision of voluntary accounting disclosures is negatively associated with earnings management. The study indicates that sound financial indicators and good news and prospects are likely to motivate firms to provide voluntary disclosures in order to attract investors' attention and communicate their managerial superiority or potential. Less information asymmetry and earnings management would lead to the disclosure of informative accounting information and would subsequently assist investors in making efficient decisions.
