Thanks for the response. I actually have applied to, and been accepted into, NYU's Global Health MPH program for this fall, as that was alternate route I was considering. Deadline to accept or enroll is April 18th for me. I have (so far) decided on a masters in economics as it would present me as a more unique candidate for medical schools. I came to this conclusion after speaking several physicians on admission committees. They informed me they would take a second glance at someone with an average (for them) MCAT score and a masters in a subject that is not directly related to Medicine, as nearly half of their applicants have MPHs. At the end of the day, what will matter most is my MCAT and GPA, and I feel as long as I do well with my masters program, that will benefit my GPA.
At the end of the day, I am not fully committed to a PhD in economics, which is why I want to pursue a masters. . If I do not do well on my entry exam for med school, a masters in economics is still useful for either a PhD or a JD. I do want to stress, I feel equally torn between all three fields (medicine, law, economics), but given my recent work in EMS I want to see if I am cut out for medicine. I am very fortunate that I have been given a large scholarship from the NSSR, so the degree is actually less expensive than if I went to an in-state program. The one thing I am concerned about is getting into a PhD program outside the heterodox community if I complete a masters at the NSSR.
