To celebrate my first day Visiting NUS next week, I will be giving away free copies of my Fundamentals book on Monday 8/26/13. The new version now includes a good example of a regression discontinuity design (for testing for whether California's energy efficiency laws have caused the Rosenfeld Curve) and many other ideas that closely link micro environmental economics to basic econometrics. Since 99.9% of the economics profession has never read an environmental textbook, I figure that there are a lot of possible sales here.
