Mystery at Harvard

Our story of the week concerns neither the Group of 20 meeting at Cannes, nor the Greek drama unfolding at Athens, nor the anonymous charges of sexual harassment against Herman Cain, nor even the prospect of a return to prison by Miss Lohan. Rather it turns out to be the mystery that has erupted at Harvard. It came into focus in the wake of the protest that took place Wednesday, when students of Professor Greg Mankiw walked out of his famous Economics 10 class because, in their reckoning, the professor, a former adviser to President George W. Bush, pays too much attention to Adam Smith and not enough to John Maynard Keynes and, in any event, fails to deal with the problem of the exploding inequality of incomes.
