Would it be fairly easy to transition from Econ and Public Policy over to Political Science for a PhD? Here's my profile if it makes it any easier:
Undergrad at Arizona State: BA Economics (3.85 GPA), minor Political Science
Economics: Macro Principles (A), Micro Principles (A), Intermediate Micro (A), Immigration & Econ (A+), Intermediate Macro (A), Money & Banking (A+), Labor Economics (A), Game Theory (B), Capstone (A+), International Economics (A)
Math: Calc 1 (A), Calc 2 (C), Statistics (A), Calc 3 (B), Proofs (A-), Econometrics (A+), Linear Algebra (B+), Real Analysis (B+), Differential Equations (A)
Grad at Arizona State (Master of Public Policy): GPA 3.98
Public Service Research I (basically applied econometrics) (A), Microecon of Public Policy I (A+), Public Service Research II (A+), Program Evaluation (A+), Public Policy Analysis (A), Microecon of Public Policy II (B), Applied Econometrics (A-), Public Budgeting and Finance (A), Advanced Policy Analysis (A), Capstone (A)
GRE:
165 Q, 160 V, 4 AW
My letter of recommendations would come from professors in the School of Public Affairs, not the Econ department (although I could probably get one if I really tried from the Econ department, but it probably wouldn't be as good as my MPP recommenders). I could also get one from a research fellowship I am currently doing at George Mason University in Political Economy.
I have a paper published in a lower-tier Public Policy journal of which I am the sole author and will have some experience with research with my fellowship at George Mason.
I also have 2 years of work experience, some research experience at a think tank and 1.5 years in state government as an Analyst.
From what I've read, work experience can be helpful for Public Policy, but for other fields like Econ and Poly Sci it doesn't really matter unless it's research in the field. Would it be a safer bet for me to stay Public Policy or switch to Poly Sci or back to Econ?
