and Ng (1996) to detect the causality in variance. We find evidence of strong contemporaneous causality that is indicative … of the mixture of distribution hypothesis of information flow. We also detect, although not as strong, lagged causality … futures, where bi-directional causality has been reported. We hypothesize that this is probably due to the special nature of …

The efficient-market hypothesis (EMH) is one of the most important economic and financial hypotheses that have been tested over the past century. Due to many abnormal phenomena and conflicting evidence, otherwise known as anomalies against EMH, some academics have questioned whether EMH is...

As this error-correction mechanism appears to be rather symmetric, and as the Granger causality tests … suggest different causality patterns for individual stocks, none of the two markets emerges as the dominant one.

The goal of this paper is to assess the money market in the Czech Republic from 1993 to 1997. The specific interest is in interactions between short and long interest rates, and between exchange and interest rates. During the financial crisis of 1997 the prevailing links among monetary variables...

There has been a common belief among stock market practitioners that stock prices move along with trading volume creating certain patterns in price and volume formation. Nevertheless, the above argument was hardly recognised by the academic community since for a number of years statistical...

Tests of causality in variance in multiple time series have been proposed recently, based on residuals of estimated … GARCH (or BEKK), and construct a Wald test on noncausality in variance. We compare both approaches to testing causality in …
