This paper examines the impact of foreign real estate on land prices in Mauritius. Using a panel dataset comprising price, quantity and other information for a variety of luxury villas and apartments, we show that the price of land paid by locals has been pushed up by a modest 4–22% in total as a result of these developments. We also examine the determinants of the prices of the dwellings in these schemes, finding that they are strongly related to the sizes of the plots, whether they have ocean views, and the desirability of the region in which they are sited, although there remains considerable unexplained heterogeneity.
