"A delightful tour of the arguments and evidence behind the debate [around open borders]... What's refreshing about the way that Caplan responds to the likely criticisms of his thesis is that he's thoughtful and generous. Nobody is accused or racism or some other less-than-pure motivation." --Bloomberg Opinion

"[Caplan's] numbers-don't-lie arguments are supported by comprehensive research...makes easy dismissal impossible. His partner-in-insight Weinersmith provides crisp, easy-to-grasp artistic support, with his own occasional insertions of humor." --Booklist, starred review

"A highly effective way to talk about an issue that remains a nonstarter for so many nationwide." --Kirkus

"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." --Tyler Cowen, Marginal Revolution

"An easy-to-read contrarian take from an economist who is right about most everything." --John Stossel

"A welcome counterpoint to the rampant fear-mongering that all too often dominates airwaves and political campaigns." --Paste Magazine

"A compelling contribution to the debate over one of the most significant issues of our time." --Reason

"Just like John Stuart Mill's The Subjection of Women 150 years ago, this book advances a sustained argument so compelling that it just might shift the moral foundations of the world." --Scott Aaronson, University of Texas at Austin

"A tour de force graphic novel illustrating one fundamental truth: there's nothing more American than being an immigrant." --Jeff Atwood, cofounder of Stack Overflow and Discourse.org

"Caplan and Weinersmith have pioneered a new format: a comic book that's quantitative and informative while remaining thoroughly entertaining. Whether you support more migration or not, Open Borders will quickly give you a balanced understanding of what serious research has to say about how open borders would affect America." --Robert Wiblin, director of research, 80,000 Hours

"A clear and inescapable economic, moral, and political case for reopening the borders that artfully counters the common objections." --John H. Cochrane, Hoover Institution at Stanford University
