I was accepted into an MA in economics at a very prestigious school without funding and a PhD in politics at a reputable state school with full funding/stipend. My intended research in the PhD program is political behavior/behavioral economics, and the MA training would probably enhance my PhD research as it covers formal economic knowledge that wouldn't be covered in my PhD studies + more rigorous than the economics classes available at the state school. Would it be possible to complete both programs simultaneously, e.g. take a 1-year deferral from the MA, start the PhD, and then start the MA as a 2nd year PhD when there is more teaching/research and not as many classes left to attend?
Obviously, if I go through with this, I will make sure that both programs are ok with this, so my question is more about the feasibility of studying in 2 programs simultaneously and completing them successfully. The universities are within 2 hours commute from each other, so it is feasible from the perspective of commute. The MA is not as research-focused, so it's basically attending classes and taking exams.
As a side note - yes, I have a major FOMO about not having a fancy diploma from a prestigious university. It's just that, given the competitive state of PhD admissions, it seems dumb to give up on a top-30 PhD program that aligns perfectly with my interests (and seems quite eager to have me too).
