Institutional Inbreeding Reexamined

Data from the 1977 Survey of the American Professoriate were used to examine the relationship between origin and productivity and institutional rewards. The analyses indicated that inbred and noninbred faculty were not significantly different on standard measures of scholarly productivity. However, when an adjustment was made for the confounding effects of time allocation, the groups could be differentiated, and inbred faculty were found to be more productive in all areas of scholarly research. Despite the results on productivity, the analyses showed that inbred faculty are paid significantly less than noninbred faculty.
