Hundreds of studies find economic freedom works

Economic Freedom in the Literature: What Is It Good (Bad) For?

Hundreds of studies in top-ranked academic journals show that economic freedom leads to positive outcomes for people, whether in increased prosperity, reduced conflict, or stronger human rights. Scholars such as Adam Smith, David Ricardo, Ludwig von Mises, F.A. Hayek, Milton Friedman, among others, argue that an economic system based on private property, competitive markets, and free trade would yield good outcomes: not only prosperity but human flourishing in many dimensions. Other scholars, among them Karl Marx, J.M. Keynes, Abba Lerner, and Joseph Stiglitz, argue that economic freedom leads to bad, or at least sub-optimal, outcomes. Ultimately, whether economic freedom yields positive or negative outcomes is an empirical question.

This chapter examines over 1,300 peer-reviewed journal articles that have cited the index published in Economic Freedom of the World: 2022 Annual Report (EFW). Of these, over 700 articles looked at the impact of economic freedom on the human condition and most find a link between high or increasing levels of economic freedom with gains in prosperity and other measures of well-being; less than one in 20 find negative consequences.

The study uses the Fraser Institute’s EFW index as its measure of economic freedom. It measures limits to freedom whether caused by overly powerful government or crony elites. The determination of “positive” outcomes—such as increased prosperity, human rights, and social development—and “negative” outcomes—such as poverty, conflict, and reduced life expectancy—is based on 721 papers in academic journals between 1996 and early 2022 that undertook fact-based studies of the impact of economic freedom, as listed in the Social Science Citations Index (SSCI).

Just over half, 50.6%, found economic freedom was related to “positive” outcomes while only 4.6% found “negative” outcomes; 44.8% did not find a clear relationship between economic freedom and either “positive” or “negative” outcomes. Economic benefits were particularly pronounced. Two thirds of the relevant studies found that economic freedom was positively related to economic growth, 72.5% to increased incomes and productivity, and 62.9% to increased entrepreneurship.
