Journal article: In the last years, there has been a shift toward more private financing of higher education in many countries. At the same time, student mobility has substantially increased. This paper analyzes in a two-region model the impact of student mobility on region-specific higher education quality with private funding. Individuals decide whether and where to study based on their individual ability and the implemented quality. We show that mobility of students affects educational quality in very differ-ent ways depending on the probability of return migration. With full return migra-tion, quality is optimally provided which is in stark contrast to the underprovision result in the case of tax financing. On the contrary, low return migration and thus more competition for students countervail the efficient provision of quality and result in too little differentiated levels or too high symmetric levels. This is in line with the overprovision result with tax financing.
