<p>Is a standard BS in applied mathematics enough to prepare you for a decent program or should you plan on taking additional coursework?</p>
<p>Is a semester each of real analysis, topology and differential enough or should you really have at least of full year of each?</p>
<p>Would it be beneficial to do a masters in pure mathematics beforehand?</p>

<p>Also, read this book.</p>
<p>Yes, what you’ve listed sounds like it should be enough (disclaimer: I’m a stats guy, not econ, though I think the math pre-reqs are pretty similar). Many PhD programs want you to take their own math courses anyway.</p>
<p>Most of the base courses in an Economics Ph.D program, from what I understand, are basically Economics’ take on Statistics, which they call Econometrics.</p>
<p>In real analysis, you may benefit from a measure theory course, since this is something probability theorists like. The thing is applied math is, while clear in terms of what it means, not easy to pin down in terms of what exactly a program covers in it.</p>
<p>My familiarity is close second hand re a Top 10 program. Short answer: the more Math, the better. Complex Analysis is helpful. My D had a Math major but did not take DiffEQ, might rethink that one now. The highest Stats or Econometrics class <em>that you can do well in</em> would also be helpful. Game Theory would not be amiss.</p>
<p>Wouldn’t necessarily suggest a Masters in Math, but of your cohort, you will find that most of the international students already have a Masters in Econ or equivalent, therefore making much of the first semester, at least, review.</p>
