An Introduction to Empirical Microeconomics by [Kahn, Matthew E.]

7. My New Book on Microeconomics Problems

This Amazon Book consists of many new applied micro questions to help young economists think about economic logic. The problems are not very challenging in terms of math content but they are meant to convey the power of price theory as a logical tool. The point of this book is to give readers a sense of how Gary Becker and Sherwin Rosen pushed students to think about interesting economics problems using the basic logic of microeconomics.
