Blogging will be slow over the next week or so. I will be busy reading the new Harry Potter book--out loud to my older son, as I read the previous six volumes. He can now read them himself, but reading them out loud together has become a tradition for us.
Addendum: Megan McArdle explains that she is not a Potter-head because J.K. Rowling falls short on basic economic principles.
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.
