The Social Network of Intellectual Collaboration (2009-2011)
We assume a weighted but undirected link between two researchers whenever one acknowledges the other on a published research paper. The weight corresponds to the inverse number of authors. Additionally, we assume an undirected link of weight 1 between every pair of authors. Weights are additive.
We have used all acknowledgments from all published research articles published in six journals: The Journal of Finance, The Review of Financial Studies, the Journal of Financial Economics, the Journal of Financial Intermediation, the Journal of Money, Credit & Banking, and the Journal of Banking and Finance.
