Two Updates

A couple of weeks ago, I mentioned the Harvard students walkout on Mankiw's introductory economics class. Gabriel Bayard and Rachel Sandalow-Ash, apparently two Harvard undergrads, had an article in the Harvard Crimson a couple of tuesdays ago. This article has better points than the "Open Letter to Greg Mankiw" closer to the date of the walkout. Daniel MacDonald has other links.

Last October, I briefly surveyed some experimental evidence, including a paper by Romer and Romer, demonstrating the existence of the Keynesian multiplier. Christina Romer has a more comprehensive presentation of the evidence. (Hat tip: Paul Krugman.)
