As Steven Levitt and his blockbuster book Freakonomics and Tyler Cowen and his recently published and wonderful-to-read Discover Your Inner Economist have shown, there still is some role for microeconomic analysis when thinking about individual behavior, especially if the goal is to entertain and sell books.
