<p>I have read that someone going into grad study in econ should have a very good math background, but that their econ background is not that important (since they will learn the econ in grad school).</p>
<p>See, e.g., <a href=“Wesleyan’s Blog System”>Wesleyan’s Blog System; "Preparing: Math. The most important thing in admissions is your math background (more than economics itself I suspect most econ PhD programs would love physics and engineering majors). "</p>
<p>Also <a href=“http://economics.uchicago.edu/graduate/apply.shtml:[/url]”>http://economics.uchicago.edu/graduate/apply.shtml:</a> “Admission to graduate study requires a bachelors degree or equivalent. This degree need not be in economics, although some background in Economics is certainly desirable.”</p>
