Analyzes collaboration on GitHub through gravity model typically used to analyze trade and migration. Uses data from GHArchive (commits) and GHTorrent (users; only a small subset identify location and these are used). Shows "flows" between jurisdictions from contributors to project maintainers. Among jurisdictions with the most users, flows are more heavily inbound to the US maintained projects and more heavily outbound from German contributors. Using a gravity model and the top 500 cities GitHub users identify as their locations, authors find statistically significant decrease in collaboration with increase in distance, though of lower magnitude than found in studies of trade and migration.
