Scientists are embedded in a community in which knowledge is shared. While the importance of peer effects in science is well-established, the focus of this paper is novel in that it studies the influence of network position on these effects. Using a new measure, brokerage degree, I show that network position is crucial in determining scientific production by facilitating access to other scientists’ non-redundant knowledge through coauthorship links. Identification results from variation in the position of stars who died unexpectedly. Heterogeneity in treatment effects - losing a star-coauthor - is on the same order of magnitude as average treatment effects.
