Robert Frank (Econ prof at Cornell) has an interesting opinion piece in a recent LA Times. There are several parallels with this line of reasoning and the article I linked to in the last post. I'm not a fan of the political turn that Frank takes in the last two sentences. As you know, I think that our job as economists is to be as apolitical as possible, but I wanted you to read this.
Frank's article is based on his recent book "The Darwin Economy". John Whitfield of Slate reviews the book and provides another perspective (part critique, part agreement) on the issue.
