Event Series Industrial organisation

The CEPR Virtual IO Seminar

Series started 22 September 2021

The CEPR Virtual IO Seminar (VIOS) was created to provide an alternative to IO seminars cancelled due to travel restrictions brought on by the Coronavirus. The long-run goal, however, is to turn it into a permanent platform for sharing the benefits of regular IO seminars. Seminars are balanced between both theoretical and empirical approaches to IO. Presentations last for about 45 minutes, followed by 5 minutes of formal discussion and then 10 minutes of Q&A.

All seminars take place on Wednesdays at 3PM (Paris time) on Zoom.
