The Conditional Heteroscedasticity Of The Yen-Dollar Exchange Rates, Yiu Kuen Tse

This paper examines the conditional heteroscedasticity of the yen-dollar exchange rate. A model is constructed by extending the asymmetric power autoregressive conditional heteroscedasticity model to a process that is fractionally integrated. It is found that, unlike the equity markets, the appreciation and depreciation shocks of the yen against the dollar have similar effects on future volatilities. Although the results reject both the stable and the integrated models, our analysis of the response coefficients of the past shocks and the application of the models to the estimation of the capital requirements for trading the currencies show that there are no substantial …
Term Structure Of Interest Rates In The Singapore Asian Dollar Market, Tom K. Y. Lee, Yiu Kuen Tse
Term Structure Of Interest Rates In The Singapore Asian Dollar Market, Tom K. Y. Lee, Yiu Kuen Tse
Research Collection School Of Economics

The extended models permit autocorrelation, skewness and leptokurtosis in the residuals. The robustness of the empirical tests with respect to alternative specifications of the ARCH process is examined. It turns out that there is significant time-varying term premium, and this conclusion is independent of the hypothesized ARCH model.
