Economists have more empirical tools—more data and more sophisticated ways of testing those data—than ever before. But unless those who employ these techniques also practice what the authors call “mainline” economic thinking, these new empirical methods are liable to generate more heat than light. In this book, Matthew D. Mitchell and Peter J. Boettke summarize the ideas of mainline economics. They begin with a puzzle that has vexed economists for more than 200 years: Why are some societies fabulously wealthy while others are miserably poor? They briefly survey the empirical tools that might answer this question and show that this puzzle cannot be understood without grounding the analysis in theory, suggesting that the first place to start is with mainline economic theory. Throughout the discussion, they offer the reader examples of how these tools have helped researchers and policy analysts bridge the gap between ideas and real-world problems.
