In this study, we used the PSTR (panel smooth transition regression) model to investigate the nonlinear relationship between beta (systematic risk) and returns (world market excess returns) for net oil export and net oil import groups. We set the volatility of world market excess return as the...

This study proposes a process for observing evidence of insider trading in the Athens Stock Exchange (ASE). This is performed by building an environment which, based upon previous research, common sense and information technology, may be used for observing such evidence. It is designed to be...
