This paper presents and implements a number of tests for non-linear dependence and a test for chaos using transactions prices on three LIFFE futures contracts: the Short Sterling interest rate contract, the Long Gilt government bond contract, and the FTSE 100 stock index futures contract. While...

Many popular techniques for determining a securities firm's value-at-risk are based upon the calculation of the historical volatility of returns to the assets that comprise the portfolio and of the correlations between them. One such approach is the JP Morgan RiskMetrics methodology using...

This paper examines the transmission of shocks between the US, Japanese and Australian equity markets. Tests for the existence of linear and non-linear transmission of volatility across the markets are performed using parametric and non-parametric techniques.

A number of recent papers have employed the BDS test as a general test for mis-specification for linear and nonlinear models. We show that for a particular class of conditionally heteroscedastic models, the BDS test is unable to detect a common mis-specification. Our results also demonstrate...

There is much evidence in the literature that the volatility of asset returns, in particular those from stock markets, show evidence of an asymmetric response to good and bad news. This paper considers the impact of news on time varying hedges for financial futures. The models are compared with...

The usual measure of the undiversifiable risk of a portfolio is its beta. Recent research has allowed beta estimates to vary over time, often based on symmetric multivariate GARCH models. There is, however, widespread evidence in the literature that the volatilities of asset returns, in...
