The stochastic volatility model usually incorporates asymmetric effects by introducing the negative correlation between the innovations in returns and volatility. In this paper, we propose a new asymmetric stochastic volatility model, based on the leverage and size effects. The model is a generalization of the exponential GARCH (EGARCH) model of Nelson (1991). We consider categories for asymmet...

This study employs the asymmetric threshold cointegration test suggested by Enders and Siklos (2001) and creates EC-EGARCH(1, 1)M model to investigate the pass-through of money market rate to banking retail rates in Taiwan and Hong Kong. It further explores the impact of interest volatility on interest rates. Over the period of February 1988 to December 2004, we find that the interest pass-thou...

In this paper, we investigate the long run dynamics of the intraday range of the GBP/USD, JPY/USD and CHF/USD exchange rates. We use a non-parametric filter to extract the low frequency component of the intraday range, and model the cyclical deviation of the range from the long run trend as a stationary autoregressive process. We find that the long run trend is time-varying but highly persisten...
