Law, finance, and emerging market returns

This paper investigates how legal foundation influences the return distribution, the growth rate of market capitalization, the ratio of market capitalization to gross domestic product (GDP) and the correlation structure of emerging market indices with developed market indices. Using a sample of 24 emerging markets, we find that emerging markets from the French [civil] law systems earned higher returns, have higher correlations with the world market portfolio, higher average growth rates in market capitalization and lower average market capitalization to GDP than their English common law counterparts. Finally, most emerging markets returns are more highly correlated to the returns of developed markets with an English common law tradition. Our results suggest that diversification potential is highest with the English common law emerging markets but that the diversification benefits come at the cost of reduced returns.
