“A phenomenal achievement. [Open Borders] is a landmark in economic education, how to present economic ideas, and the integration of economic analysis and graphic visuals. I picked it up not knowing what to expect, and was blown away by the execution . . . This book is one of the very best explainers of the gains from trade idea ever produced, and it will teach virtually anyone a truly significant amount about the immigration issue, as well as economic analytics more generally.”
