Dear all,<\/p>\n
We are pleased to announce that Maximilian Schaefer <\/strong>(IMT)\u00a0<\/strong>will be the next speaker in our CERNA Research\u00a0Seminar<\/strong>. The\u00a0seminar\u00a0will take place\u00a0Thursday<\/strong>\u00a0(not Wednesday this time) May 7, 2026 <\/strong>at 4 PM <\/strong>in Salle Chevalier.<\/p>\n Max will present his paper:<\/p>\n Generative AI and the Division of Labor in Knowledge Work<\/strong><\/p>\n Open source development is a key input to collective innovation and production of digital commons. Generative AI coding assistants are reshaping how developers write and maintain code, while major digital firms have expanded their open source footprint, altering the balance between corporate and community participation. This paper studies how the release of ChatGPT-3.5 in November 2022 modified the patterns of open-source activity and whether these changes differed between institutional (firm-linked) and independent developers. Using data on 1M GitHub developers and their activity on the platform, we classify contributors as institutional or independent and estimate a difference-in-differences model with two-way fixed effects. We find that public open source activity declines after the AI shock, as measured by the number of public repositories per developer, while surviving projects tend to be of higher quality: they receive more stars, are more likely to be outgoing forks, and show higher contribution volumes. Institutional developers reduce their public footprint more intensely but experience larger gains in visibility and quality.<\/em><\/p>\n There will be an opportunity to schedule individual meetings and\/or join dinner with Max before the seminar.<\/p>\n
