An EGARCH model in which the conditional distribution is heavy-
tailed and skewed is proposed. The properties of the model, including
unconditional moments, autocorrelations and the asymptotic distribu-
tion of the maximum likelihood estimator, are obtained. Evidence for
skewness in conditional t-distribution is found for a range of returns
series and the model is shown to give a better t than the correspond-
ing skewed-t GARCH model.
