Deidre makes an excellent point about Lucas. An outstanding MA student here at UConn went to Chicago for his doctorate. He called me after taking macro at Chicago to say how grateful he was that our Master's course had covered each school in macro--so he had context (history) to frame what Lucas was teaching. He told me it was tragic to see that his fellow students understood nothing about the different approaches to macro--and many would end up re-inventing earlier ideas out of ignorance. Fred Carstensen
