How well are international branch campuses serving students?

The academic literature and professional journals both reveal no shortage of criticisms of the international branch campus. Yet, each year, more branches are established all around the world, and existing campuses continue to expand. So, it seems that there must be a demand for these campuses. But how well are they actually serving students? It is interesting that the growth of student numbers at international branch campuses does not seem to have affected enrollments at the home campuses of Western universities. This implies that branch campuses have found a new, additional demand for higher education.
