PPE ( Politics, philosophy, and economy) vs political science vs political economy?
Most employable
Highest salary
Note: I am interested in all of those, but can’t choose.
Majors don’t earn salaries; jobs do. These three majors are very similar to each other and it is unlikely that the job prospects among them vary very much. The political economy major and potentially PPE may include more economic analysis classes with quant training, but then again you can also take those classes in a straight-up political science major if you want, so it won’t matter.
Thing is, though, PPE and political economy are far less common than political science.
