The fact that weak instruments lead to spurious inference is now widely recognized. In this paper we ask whether spurious inference occurs more generally in weakly identified models. To distinguish between models where spurious inference will occur from those where it does not, we introduce the...

In this paper we consider a GARCH-in-Mean (GARCH-M) model based on the so-called z distribution. This distribution is capable of modeling moderate skewness and kurtosis typically encountered in financial return series, and the need to allow for skewness can be readily tested. We apply the new...

This paper examines stock market behaviour in India, Sri Lanka, Pakistan, and Bangladesh employing unit root tests, autocorrelation tests and spectral analysis. Evidence suggests that all markets exhibit a random walk. The multivariate cointegration tests based upon the Johansen Juselius (1988,...
