We examine whether the differences in the legal origins of countries (Common Law versus Civil Law) can explain the variations in the price efficiencies of the stock markets of different countries. Based on multifractal detrended fluctuation analysis of the daily stock indices of 34 countries over 21 years, we find that the stock price indices in Common Law origin countries show greater price efficiency than the stock price indices in Civil Law countries. These results provide additional evidence that the legal origins of countries affect their economic activities and outcomes.

This paper links banking system development to the colonial and legal history of African countries. Based on a sample of 40 African countries from 2000 to 2018, our empirical findings show a significant dependence of current financial institutions on the inherited legal origin and the colonization type. Findings also reveal that current financial legal institutions are not major determinants of banking system development, and that institutional development and governance quality are more important. A high share of government spending relative to GDP also positively affects banking system development in African countries.
