Hi all,
I'm the Director of Graduate Studies in CU-Boulder's Political Science Department. While I certainly won't disagree with previous posts that Harvard, Wisconsin, and UCSD are the top places to study political economy, I'd also urge potential applicants to take a look at the quality of our faculty in the area. PE is one of our area's of strength, both in comparative and IR.
