Concentration and Diversification in a small island economy : Mauritius

The objectives of this paper are partly to add to the worldwide literatureon contemporary levels of concentration – but in our case for a small islandeconomy, and partly to provide a reference study which yields a concise andaccessible source for anyone interested in gaining a quick picture of the state ofconcentration and diversification of the leading firms in Mauritius. In the main, wehave confined ourselves to fact-finding at this stage, and the novelty of the worklies in the descriptive statistical framework within which it is presented.Nevertheless, it is inevitably policy relevant. In our opinion it suggests the needfor continuing vigilance of concentration in individual markets, but also moreresearch in the potential competition implications of the fact that the very largestfirms have leading, possibly dominant, market shares in more than one industry –is such diversification a cause for competition concern?
