Bivariate error correction FIGARCH and FIAPARCH models on the Australian All Ordinaries Index and its SPI futures
نویسنده
چکیده
In this paper we extend the univariate FIGARCH and FIAPARCH models to a bivariate framework. We estimate bivariate error correction FIGARCH and FIAPARCH models between the All Ordinaries Index and its SPI futures using constant correlation and diagonal parameterisations. We therefore employ a flexible estimation approach that captures the long run equilibrium relationship between the two markets, bi-directional return causality, long memory and asymmetries in volatility, and time varying correlations. The results strongly support the use of this approach. Strong bi-directional return causality exists with the index bearing the burden of adjustment to deviations from long run equilibrium. The results also illustrate the importance of allowing for long memory, asymmetries in volatility, and time varying correlations. JEL classification: GO; C3; C51

Basis convergence and long memory in volatility when dynamic hedging with SPI futures
This paper examines the importance of basis convergence and long memory in volatility when estimating minimum variance hedge ratios (MVHRs) using SPI futures. The paper employs a bivariate FIGARCH model with a maturity effect to model the joint dynamics of the Australian All Ordinaries Index and the basis. This new approach allows for long memory in volatility, time varying correlations and the...
متن کاملLong term hedging of the Australian All Ordinaries Index using a bivariate error correction FIGARCH model
This article compares the performance of bivariate error correction GARCH and FIGARCH models when estimating long term dynamic minimum variance hedge ratios (MVHRs) on the Australian All Ordinaries Index. The paper therefore introduces the bivariate error correction FIGARCH model into the hedging literature, which to date has only employed the GARCH class of processes. This is important for tho...
متن کاملBivariate FIGARCH and fractional cointegration
We consider the modelling of volatility on closely related markets. Univariate fractional Ž . volatility FIGARCH models are now standard, as are multivariate GARCH models. In this paper, we adopt a combination of the two methodologies. There is as yet little consensus on the methodology for testing for fractional cointegration. The contribution of this paper is to demonstrate the feasibility of...
متن کاملLong memory mean and volatility models of platinum and palladium price return series under heavy tailed distributions
South Africa is a cornucopia of the platinum group metals particularly platinum and palladium. These metals have many unique physical and chemical characteristics which render them indispensable to technology and industry, the markets and the medical field. In this paper we carry out a holistic investigation on long memory (LM), structural breaks and stylized facts in platinum and palladium ret...
متن کاملDynamic Hedging using a Bivariate Markov Switching FIGARCH model
This paper develops a bivariate Markov Switching FIGARCH (MS-FIGARCH) process with constant and time varying transition probabilities as a way of modeling spot futures dynamics. An application of the model illustrates that the S&P500 and its futures exhibit long memory in volatility and structural breaks that are driven by changes in the cost of carry. The model with constant transition probabi...
