Purpose -- the objective of this thesis is to empirically test the level of interdependence across commodity markets in terms of return volatility spillover, namely, corn, wheat, soybeans and soybeans oil, and to uncover the impact of macroeconomic announcements on the measurement of integration among those commodities. This will help us to investigate the extent to which different agricultural commodities can be considered as an asset class and to determine whether portfolio diversification across different agricultural commodities can still lead to risk reduction benefits, in light of the ...

Purpose – This thesis has two objectives. The first one is to test empirically the level of interdependence across major stock markets returns, namely, US, EU, and Asia in terms of return and volatility spillover. The second one is to evaluate the impact of news announcements on their stock market volatility. Design/methodology/approach – To model the volatility of the three above mentioned stock markets we apply a battery of univariate time series models from the GARCH family. Dickey Fuller unit root test is used in order to ensure that the three return series are stationary. The mean equation ...

Purpose: The purpose of this study is to empirically test the level of interdependence between three major assets: Gold, crude oil and USD index in terms of the return volatility spillover effects. This helps investors managing their portfolios and provides them with sense of direction on how to use these assets in portfolio diversification leading to a risk reduction benefits. Design/methodology/approach: Gold, oil and USD index volatilities are estimated using EGARCH (1, 1) model after detecting the stationarity and heteroskedasticity of the sample using the following diagnostic tests: Augmented ...
