This empirical study investigates the nature of spillovers between precious metal prices, i.e. gold and silver, stock markets and a number of macroeconomic variables for the G7 countries over the period 1981 to 2010. Through the methodological approach of the factor-augmented vector...

This article develops a method of nonlinear modelling for the dividends of the Group of seven (G7) indexes using threshold techniques: Smooth Transition Autoregressive Models (STAR). First, smoothness and nonlinearity are justified by the presence of heterogeneous expectations and companies of...

In this article, we investigate the hypothesis of efficiency of central bank intervention policies within the current global financial crisis. We firstly discuss the major existing interventions of central banks around the world to improve liquidity, restore investor confidence and avoid a...

The aim of this article is to study linkages between equity and information technology sector prices. We thus investigate the price adjustment dynamics of the Information Technology (IT) sector in response to the 2007--2009 worldwide market shock for two representative developed countries...

This article studies the efficiency of the aluminium market based on contracts traded on the London Metal Exchange (LME) over the last 3 decades. We test for both short- and long-run efficiency using nonlinear cointegration and Error Correction Models (ECM). Our findings suggest the following...

Appropriate modelling of the process of volatility has implications for portfolio selection, the pricing of derivative securities and risk management. Further, a large body of research has suggested that both long memory and structural changes simultaneously characterize the structure of...

This study employs 14 global economic and financial variables to predict the return of the Islamic stock market as identified by the Dow Jones Islamic Stock Market (DJIM). It implements alternative forecasting methods and allows for nonlinearity in the multivariate predictive regressions by...

This article examines the existence of long memory in daily stock market returns from Brazil, Russia, India, China and South Africa (BRICS) countries and also attempts to shed light on the efficacy of autoregressive fractionally integrated moving average (ARFIMA) models in predicting stock...
