<p>why are you interested in math-heavy economics courses? just take relevant math courses… (avoid this advice if your idea of “math-heavy” is econ 101a…)</p>
<p>good classes to consider are the ones you already knew, so yeah, 103, 104, and 141/142. </p>
<p>aside from that maybe dive around in some ODE/PDE classes </p>
<p>if you’re interested, try for math 105/202b.
if you’re bored, try for a mathy game theory class like stat 155.
maybe time series -stat 153, stochastic processes -stat 150 if you’re looking into grad school or a career in this direction.</p>
