As you may imagine, I enjoy reading the popular press books and articles describing new economic research. Some are better than others. Most recently, I finished Tim Hartford's The Logic of Life, which is amongst the best popular press economics books (also amongst the best are Freakonomics and Super Crunchers). Some of the topics include game theory and poker, the market for marriage and divorce, the job market (and why your lazy boss is paid so much), rational racism (rational not good), and why subsidizing city living would be good for the environment. It's worth a read.
