This study examines the published estimates on the relationship between economic freedom, as measured by the Economic Freedom of the World (EFW) index, and measures of growth, income, investment, and inequality. We obtained 696 point estimates for economic freedom-growth from 54 articles, 386 estimates for economic freedom-income from 23 articles, 343 estimates for economic freedom-investment from 32 articles, and 759 estimates for economic freedom-inequality from 26 articles. The published estimates support the view that economic freedom is positively related to growth, income, and investment. The level of economic freedom appears to be simply unrelated to inequality, though increases in economic freedom may correlate with higher inequality.

经济自由与增长、收入、投资和不平等：文献的定量总结

本研究考察了已发表的对经济自由度（以世界经济自由度 (EFW) 指数衡量）与增长、收入、投资和不平等衡量标准之间关系的估计。我们从 54 篇文章中获得了 696 点对经济自由增长的估计，从 23 篇文章中获得了 386 点对经济自由收入的估计，从 32 篇文章中获得了 343 点对经济自由投资的估计，从 26 篇文章中获得了 759 点对经济自由不平等的估计。公布的估计支持经济自由与增长、收入和投资正相关的观点。经济自由水平似乎与不平等无关，尽管经济自由的增加可能与不平等加剧相关。
