This paper proposes a simplified multivariate GARCH model (the S-GARCH model) that involves the estimation of only univariate GARCH models, both for the individual return series and for the sum and difference of each pair of series. The covariance between each pair of return series is then...

This paper proposes a simplified multivariate GARCH model that involves the estimation of only univariate GARCH models, both for the individual return series and for the sum and difference of each pair of series. The covariance between each pair of return series is then imputed from these...

Despite significant theoretical and empirical developments in the capital structure literature, the trade-off theory and the related question of the optimality of the gearing ratio remain the subject of intense debate. The pecking order theory emerged to directly contrast with the implications...

We examine the impact of industry membership on the capital structure dynamics of UK quoted firms over the period 1968 to 2006 by analysing how the components of common gearing ratios are adjusted in relation to one another. More specifically, if we find evidence of a cointegrating relationship...

The authors propose a simplified multivariate GARCH (generalized autoregressive conditional heteroscedasticity) model (the S‐GARCH model), which involves the estimation of only univariate GARCH models, both for the individual return series and for the sum and difference of each pair of series....
