A curated collection from the most readable economics blog in the universe. Over the past decade, Levitt and Dubner freely admit that most of their posts were rubbish. But now they've gone through and picked the best of the best. You'll discover what people lie about, and why; the best way to cut gun deaths; why it might be time for a sex tax; and, yes, when to rob a bank. (Short answer: never; the ROI is terrible.).
