This paper explores the effects of limited experience resulting from professional immobility on faculty teaching and research role orientations and faculty productivity. The correlates of institutional inbreeding treated as a form of immobility are examined. Data are provided from a large-scale, nationally representative survey of college and university faculty members. This study examines a broad array of dependent variables, including time spent in research, self-reported commitment to teaching, and total number of published articles during a scientists' professional lifetime.
