We report evidence indicating that Bitnet adoption facilitated increased research collaboration between US universities. However, not all institutions benefited equally. Using panel data from seven top engineering journals, Bitnet connection records, and a variety of institution ranking data, we...

This paper provides evidence that students in the mid-1990s learned to use the Internet at university and then continued use after graduation, highlighting a micro-level role for institutions in diffusion. In particular, it shows that university attendance in the mid-1990s had a larger effect on...
