Thank you.
I anticipated that question might come, because I noted it had been raised before, so I did a little quick checking. The fact is that concentration is not a new phenomenon. In 1997, if you look at total federal support for university research, the top 15 institutions accounted for 75%. In 1991, the top 15 accounted for 74.5%, and in 2004-05 they accounted for 76%. At the bottom of that list of 15, some move in, some move out, but concentration is not new. It happens in other countries as well.
That said, our view is that excellence does not have an address. You will find pockets of research excellence, or the potential, in small, medium, and large institutions. The key is to ensure that those institutions have the capacity to compete in national peer-reviewed positions on the basis of their own excellence.
