What Determines Australia's Foreign Equity Investment?

Abstract

In light of the recent changes to superannuation policy in Australia, the corresponding heightened exposure to equity markets has highlighted the importance of portfolio diversification as a means to reduce income risk. The International Capital Asset Pricing Model of Sharpe (1964) and Lintner (1965) suggests that in order to obtain maximum gains from diversification, investors hold too little wealth in foreign assets. This large discrepancy between theory and data is known as the home income bias puzzle and still remains robust despite the recent liberalisation of financial markets and removals of direct barriers to investment. This thesis empirically investigates the distribution of Australian holdings of foreign equities and considers the determinants of equity home bias for a sample of 25 countries. The IMF's high quality Coordinated Portfolio Investment Survey (CPIS) dataset is appropriate for this purpose and is utilised over the period 2001 to 2005. The key findings are that indirect barriers to international investment and information costs are important factors behind international investment patterns and the home bias puzzle.
