This paper considers the ability of the Power ARCH model introduced by Ding, Granger and Engle (1993) to capture the stylised features of volatility in 17 heavily traded bilateral exchange rates. This Power ARCH model nests a number of models from the ARCH family. The relative merits of these...

The weekend effect is an empirical enomaly that has attracted substantial attention. Following the work of Connoly (1989) it is necessary to revisit previous empirical work. In this paper we examine the weekend effect in Malaysia over the period 1986-1993.

The modelling and forecasting of exchange rates and their volatility has important implications for many issues in economics and finance. This paper compares the ability of Autoregressive Conditional Heteroscedasticity, Autoregressive and Mean models to forecast the magnitude of change in 19...

This paper esplores the applicability of ARCH/ GARCH models to Australian financial structure data. In particular we focus on the extent to which the parameters of the models change over time by analysing the data contract. We find the results to vary over time and that simple models such as the...
