I am currently getting my masters in Public Policy and considering getting a PhD in the near future. I'm looking for advice on whether to pursue a PhD in public policy or economics. I've heard that public policy phds are not as well received as econ phds on the job market. My fear with applying to the econ phd program is that I have not taken the advanced course work in linear algebra, matrix theory, real analysis and the other standard econ prerequisites. I will say though that a majority of my courses in my masters program have been quantitatively focused, having passed the equivalent of calc I and II, but my concern is that they are not in depth enough to make me a competitive candidate for admission.
Would something like coursera or MIT open courseware math courses in these subjects be sufficient? or should I take something for credit at a local college?
Appreciate the advice!
