Here. He's got a really bothersome video posted that's worth watching just to get a sense of what Keen's position is. I have to say, my opinion of this guy has dropped like a rock ever since this Krugman/Keen thing started. I always gave him the benefit of the doubt because so many people spoke so highly of him. The blog back-and-forth made me leery, but I figured maybe they were just talking past each other. But this video is chock full of cases where Keen is either completely ignorant or completely disingenuous when it comes to mainstream economics.
One thing's for sure though - I'm really looking forward to my Macro Political Economy class in the fall now. It's basically a post-Keynesian political economy class.
I still have a lot of respect for most of the post-Keynesianism I've run across. But this Keen guy is really starting to rub me the wrong way.
