This story is last week's news, but I thought it was interesting. A group of students in Mankiw's introductory economics class walked out on him, and posted this statement in the Harvard Political Review. Here's a story in the Harvard Crimson, and this is an interview with Mankiw on NPR.
Basically, the students are accusing Mankiw of bias. They seem to think that he might be making stuff up, there's too much Adam Smith and not enough Keynes in his course, and they're worried about the "corporatization of higher education." I think of Mankiw's intermediate macro text, for example, as pretty middle-of-the-road, and very heavy on Keynes for my taste. Obviously these students are very confused and, I think, biased. My guess is that, if I showed up to teach Mankiw's class with my non-Ivy League ways, told them I was a Democrat, and taught out of Mankiw's book, that they would not be complaining about me.
What these students don't get is that taking Mankiw's class will actually give them the knowledge they need to be more effective political leaders, in a movement that looks quite ineffective and rudderless. A good dose of serious economics can help them isolate the defects in economic policies, and can show them how they can help poor people in effective ways. Knowledge is power, as I like to tell Ron Paul's supporters, who are equally confused.
