### Summary of the study
- Authors: Dennis Essers, Francesco Grigoli, Evgenia Pugacheva
- Date: July 24, 2020
- Core objective: Study the determinants of new and repeated research collaborations using the co-authorship network of the IMF Working Papers series.
- Key context: The IMF Working Papers series is an outlet where authors express their views on topics of interest and IMF staff are not subject to “publish-or-perish” conditions, making it an appropriate testing ground to examine the endogenous nature of co-authorship formation.

### Main findings
- Network structure:
  - The co-authorship network is characterized by many authors with few direct co-authors, yet indirectly connected to each other through short co-authorship chains.
- Determinants of starting collaborations:
  - A shorter distance in the co-authorship network is key for starting research collaborations.
  - Higher research productivity helps to start collaborations.
  - Being employed in the same department helps to start collaborations.
  - Having citizenship of the same region helps to start collaborations.
- Determinants of repeating collaborations:
  - Higher research productivity helps to repeat collaborations.
  - Being employed in the same department helps to repeat collaborations.
  - Having citizenship of the same region helps to repeat collaborations.
- Cross-network-size collaborations:
  - Authors with different co-authorship network sizes are more likely to collaborate, possibly reflecting synergies between senior and junior staff members.
