So this may be an odd question, but I figure I may as well go for it. So I am currently in a PhD program at a 50-70 school (I was waitlisted at two Top 40-50 schools, but didn't get in). I am wondering if it is realistic to get into a PhD program for business, public policy, statistics, or applied math upon the completion of my current Econ PhD program in order to get a job at a research school? How likely to a Top ~20 program accept someone with a Econ PhD (especially for business or policy)? Or would I be better off doing a postdoc instead?
