We propose a new methodology for decomposing the persistence of deviations from purchasing power parity (PPP). By directly comparing the impulse response function (IRF) of a vector autoregressive (VAR) model, where the real exchange rate is Granger caused by a set of candidate variables, with...

This paper investigates the effects of imposing invalid cointegration restrictions or ignoring valid ones on the estimation, testing and forecasting properties of the bivariate, first-order, vector autoregressive (VAR(1)) model. We first consider nearly cointegrated VARs, that is, stable systems...

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,...

In this paper we provide some empirical evidence on the casual relationship between stock prices and exchange rates volatility in four East Asian countries. In order to test for causality-in-variance, we use a GARCH model for which a BEKK representation is adopted, and then test for the relevant...
