<p>I found the article really interesting. I always thought undergrad econ would include quite a bit of mathematics because many economic formulas are derived through calculus; for example, the rule of 70 (one of the first formulas you learn in econ) is derived from the formula 2 = e ^ (rt) which gives you t = ln(2)/r and ln(2) is 0.693… or approximately 0.7. I’d assume undergrad would include a lot of math; it must be quite a shock to get into a phd program and then all of a sudden be bombarded with Calc/diffyQs. They should probably prepare students better and require more math for the econ major curriculum.</p>
