This paper uses Monte Carlo techniques to assess the loss in terms of forecast accuracy which is incurred when the true data generation process (DGP) exhibits parameter instability which is either overlooked or incorrectly modelled. We find that the loss is considerable when a fixed coefficient...

This paper examines the dynamic interactions between mutual fund flows and security returns in an emerging capital market, namely the Greek one. It adopts a testing strategy not requiring pre-testing (which might generate severe biases) but simply augmenting the system (Toda and Yamamoto, 1995,...
