Book excerpt: Economic theory and a growing body of empirical research support the idea that economic freedom is an important ingredient to long-run economic prosperity. However, the determinants of economic freedom are much less understood than the benefits that freedom provides. Economic Freedom and Prosperity addresses this major gap in our knowledge. If private property and economic freedom are essential for achieving and maintaining a high standard of living, it is crucial to understand how improvements in these areas have been achieved and whether there are lessons that can be replicated in less free areas of the world today. In this edited collection, contributors investigate this research question through multiple methodologies. Beginning with three chapters that theoretically explore ways in which economic freedom might be better achieved, it then moves on to a series of empirical chapters that examine questions including the speed and permanence of reform, the deep long-run determinants of economic freedom, the relationship between voice and exit in impacting freedom, the role of crises in generating change, and immigration. Finally, the book considers the evolution of freedom in China, development economics, and international trade, and it concludes with a consideration of what is necessary to promote a humane liberalism consistent with economic freedom. Economic Freedom and Prosperity will be of great interest to all social scientists concerned with issues of institutional change. It will particularly appeal to those concerned with economic development and the determinants of an environment of economic freedom.
