I have and had a number of great PhD students (12 finished and 2 ongoing). Some have stayed in academia, many have gone into the private sector (consulting mostly). Here are some of the papers that came out of their PhD theses.
Current PhD students
Valeriia Chukaeva (working on issues in political economy) and Elshan Garashli (working on strategic information transmission)
