Hi folks,
I am a double Bus. (Finance in particular) and Econ major. My goal is to pursue a PhD in econ but I've been looking at some PhD in bus programs lately. I have a few questions that I would really appreciate it if you can answer me (I know you guys will

)
1. Do you need (and need a lot) of math? Like in Econ, I know that you need at least 3 Cal classes, Linear Alg, Diff equations, Real analysis (and more). Do you need those math classes to apply for a PhD in bus? If not, what level of math do you need? At my school, to get a BS in Bus Admin, you just College alg and basic Cal which are so easy
In addition, is there any certain courses that you need to take or you need to take just enough for a major? (is there any course in the econ dept or any other dept that is required?)
2. Why don't most Bus schools accept GRE instead of the GMAT?
3. Correct me if I'm wrong but I think I've seen PhDs in econ teach courses in Bus school but I don't think I've seen people with PhD in finance or any other aspect of business teach in an Econ Dept. Is it because of the nature of the science or what?
Thanks a bunch!!!!!!!
