The Economic Freedom of the World (EFW) index has annually provided a measure of the consistency of a nation's policies and institutions with economic freedom. With data going back to 1970 and coverage of over 100 countries, the EFW index has become an important tool for scholars studying a wide range of economic and social outcomes around the world. This book highlights contributions made to this literature that were published originally in one of the most important journals in this field, the Journal of Private Enterprise, bringing together a wide variety of studies on the role of economic freedom on economic growth, income equality, political freedom and other social goals.
