The Becker-Posner Blog, founded by Nobel Prize-winning economist Gary S. Becker and renowned jurist and legal scholar Richard A. Posner, banks its reputation on lively, thought-provoking commentary on current events, along with pithy and profound weekly essays highlighting the value of economic reasoning when applied to unexpected topics. Uncommon Sense gathers the most important and innovative entries from the blog, arranged by topic, along with updates and even reconsiderations when subsequent events have shed new light on a question. Whether it's Posner making the economic case for the legalization of gay marriage, Becker arguing in favor of the sale of human organs for transplant, or even the pair of scholars vigorously disagreeing about the utility of collective punishment, the writing is always clear, the interplay energetic, and the resulting discussion deeply informed and intellectually substantial.
