Research Productivity in a System of Universities

James Adams and Zvi Griliches

Annals of Economics and Statistics, 1998, issue 49-50, 127-162

Abstract: This paper considers research performance of U.S. universities for eight science fields. At the aggregate level we find that research output follows a constant returns to scale process. However, for individual universities we find evidence of diminishing returns. We offer two explanations for these differing results. First, data errors are more important at the individual level. Second, research spillovers exist between universities and fields that are captured only at the aggregate level.
