<p>I'll have to respectfully disagree with UCLAri. While an understanding of macro and microeconomic concepts is of benefit to any student of international relations, the study of international relations/studies/concepts does not necessarily have to focus on quantitative coursework. </p>
<p>IR scholars focus on different things -- if the OP's interest is not in economics/trade/etc. and is, instead, say, in refugee studies, cultural conflicts, child soldiering, etc. then I don't see why he should take any more thant he required econ courses for his IR major at Tufts/Gtown/JHU or wherever he may go. Instead, try to fulfill your economics requirements within your IR major with classes that relate to your interests. For example, my interest in IR is in refugee studies, so I took (in addition to basic micro/macro course), upper-level courses in the economics of migration, etc.</p>
