<p>I happen to be applying to all three of these schools (and Georgetown, go figure)...AND I'm a prospective econ major, AND I've done a lot of research, so I can tell you a lot.</p>
<p>Georgetown is, as I said earlier, one of the most policy-oriented econ programs out there. The focus is less on math and the nitty-gritty and more on practical applications. However, there's A LOT of really cool specific classes </p>
<p>FOR EXAMPLE: typical classes include "Economic Development in Southeast Asia", "Economic Issues of Social Reform", and "Assessing US and Japan Foreign Relations"</p>
<p>Northwestern is a polar opposite. Very mathy and very few super-specific "niche" classes...a solid, pure, no-frills econ program that I've heard is very rigorous. Over the past 2 years Northwestern's econ dept. has only offered about 40 classes (compared with nearly 80 for Duke) because you won't find super-specific classes offered...NWestern considers them frivolous</p>
<p>FOR EXAMPLE: Northwestern offers a class in "Econometrics" AND a separate class in "Mathematical Economics"...and no class is more specific/niche-y than "Economics of Nonprofit Organizations"</p>
<p>Duke is in the middle of the spectrum between left- and right-brained apporaches. Two things that set Duke apart are the super-vamped research initiative and also the ridiculous amount of courses Duke's econ dept. offers (alluded to above). Some are really neat, some seem too specific and niche-y to be useful. The major's core is pretty rigid and stacked...there's a lot of classes you have to take to get your degree, making this second to only Nwestern in perceived rigor.</p>
<p>FOR EXAMPLE: Courses include "Economics, Society, and Morality in the 18th Century", "Term Structure of Credit Risk", "Microfinance"</p>
<p>Cornell is also a bit like Duke in that there's LOADS of classes, though I find the selections at Cornell to be more relevant than those offered at Duke. If you're into it, there's a lot of agricultural, resource, and environmental economics at Cornell. Pretty math-y, more so than Duke and Georgetown, but less so than Nwestern.</p>
<p>FOR EXAMPLE: Classes offered include "Industrial Organization I" AND "Industrial Organization II", "Income Distribution", "Game Theory" AND "Game Theoretic Methods"</p>
<p>Hope this helps.</p>
