We demonstrate the importance of ‘social connections’ in the labor market using a novel dataset where we study the placement outcomes of doctoral students in Economics. We show that a PhD adviser’s connectedness in the co-author network matters for her student’s academic placement. An adviser’s connectedness is measured by her Eigenvector centrality rank in the co-author network defined by more than 100,000 coauthored research articles. Students of more connected advisers obtain a better initial placement compared to students of less connected advisers. We identify the impact of adviser connectedness via changes in the centrality of the adviser’s co-authors in a model with adviser-fixed effects. Additionally, we use the deaths of faculty members as an exogenous shock to show that the probability of a student being placed at a particular department reduces when the collaboration intensity between the student’s school and that department decreases due to the death. Our results contain a more general insight into any labor market with information frictions - even indirect connections can significantly affect job market outcomes.
