Economics Major with WANTING TO sorta Major in MATH

Hello had a quick question.

So I wanted to change from my current B.A in economics with math minor to applied mathematics with an emphasis in economics B.S. However I am past my second year and if I do make a switch I would have to take a bunch of GE’s like Physics, and chem.

So an alternative solution that I came up is the following. Continue being a B.A in Econ, but take more math classes than required for the minor. I plan to take 7 upper-division math courses. (the math major asks for 7 upper divs). I plan to either go to graduate school in economics or become an actuary(something along those lines). Would I be in some disadvantage in some way, just because I wouldn’t be an official Math Major, even though I took all the Math courses required? Do grad school, or businesses need to see that degree or does courses work?

By the way I already took up to vector calculus and Linear Algebra and Introduction to differential equations

The upper division math classes I plan to take are

Linear Analysis
Numerical Analysis
Real Analysis
Modern Applied Statistics
Mathematical Modeling
Complex Numbers
Ordinary Differential equations

Upper division Econ classes

Micro
Macro
Econometrics
advanced Econometrics
game theory
organizational strategy
industrial organization

Make sure you take a mathematical Probability course. Immediately after that course, take the Actuary P exam. My son did that last year and passed it with very little studying since the material was fresh. He is not sure about being an actuary, but its a good option to have. His school offers an Actuary degree which he is not doing. Your classwork looks similar to their requirements. I’m not sure you need Real Analysis unless you are considering a grad degree in Math.

The coursework is generally what is important. @NoKillli has good advice, except I would take real analysis. It’s highly recommended for those considering a graduate degree in economics. Many graduate economics programs would like to see that you have taken real analysis, multivariate calculus (calc 3), diff eq, and linear algebra.

You will need differential equations in graduate economics.

Here is what one economics department recommends for undergraduate students preparing for PhD study in economics:

So would you think that it wouldnt be at a disadvantage to the applied math majors given my plan of Econ B.A degree and all the upper div Math classes minues the GE’s?

That Berkeley list looks like a combo Pure and Applied degree. A Math degree looks to be almost a requirement.

Real 1&2, Complex, and Topology? Yikes!
