Generating pairs of focal papers.

On the left, five focal papers are illustrated, together with their keywords (ki) and the share of male-authored citing papers (in %). The table on the right shows all pairs of focal papers such that one paper of a pair is female-authored and the other paper is male-authored. Column D shows the difference in the share of male-authored citing papers for a pair, which is used as an indicator for the degree of gender homophily. Column S shows the number of shared keywords, which is used as an indicator for the similarity between two papers.
