I never liked economics because it seemed so imprecise. Real world predictions seem to be limited. Recently, however, I’ve been paying more attention to Krugman, Thaler, Shiller, Krueger, etc. Now, I feel like ignoring the topic was a bad decision. Any recommendations on great books, blogs, etc to learn more about economics?
