I just submitted to a journal my review of the book written by Robert Frank, "The Darwin Economy". My conclusion is that it is an excellent book, but that as a colleague told me, there is a significant oportunity cost to having bright academics having to spend time arguing that government is necessary. It is the existence of anti-government zealots that causes such a misallocation of resources. The book presents very interesting links among the thoughts of scholars such as Darwin, Smith, Stuart Mill and Coase. Althoug the author says that he has criticisms both for the right and for the left, don't feel guilty, the book has been written to fight the extreme right.
