Economic Freedom of the World
The foundations of economic freedom are personal choice, voluntary exchange, and open markets. As Adam Smith, Milton Friedman, and Friedrich Hayek have stressed, freedom of exchange and market coordination provide the fuel for economic progress. Without exchange and entrepreneurial activity coordinated through markets, modern living standards would be impossible.
Potentially advantageous exchanges do not always occur. Their realization is dependent on the presence of sound money, rule of law, and security of property rights, among other factors. Economic Freedom of the World seeks to measure the consistency of the institutions and policies of various countries with voluntary exchange and the other dimensions of economic freedom. The report is copublished by the Cato Institute, the Fraser Institute in Canada and more than 70 think tanks around the world.
