Abstract

In this paper, the information content of the volatility observed on portfolio flows is tried to be econometrically examined for the Turkish economy. Our findings employing EGARCH estimation methodology reveal that the volatility shocks on the portfolio flows seem to be of a quite persistent form and that the news impact extracted from the model is asymmetric such that the conditional variance of the net portfolio flows reacts more to past negative shocks than to positive innovations of the equal size. Such a result has been attributed to that inside the period under investigation an unanticipated decrease in net portfolio flows would lead to a higher level of uncertainty when compared with the uncertainty resulted from an unanticipated increase and that policy makers ought to be prudent against the increasing uncertainties in the economy especially if large portfolio outflows are to be experienced.
