When Paul Krugman and Robin Wells published their new economics textbook, I noticed some similarities to mine. So maybe I shouldn't be surprised to learn over at Amazon that they have added me as a coauthor.
I am a professor and chairman of the economics department at Harvard University, where I teach introductory economics (ec 10). I use this blog to keep in touch with my current and former students. Teachers and students at other schools, as well as others interested in economic issues, are welcome to use this resource.
