We spoke during the European winter meeting of The Econometric Society 2023 in Manchester this December in a session on relational contracting chaired by Sarah Auster (University of Bonn) and featuring very interesting papers by Peter Wagne (University of York), Mathieu V. Leduc (Paris School of Economics) and Johannes Schneider (Universidad Carlos III de Madrid). Our paper tackles contracts with interdependent preferences and answers the question on how one can incentivize a group of rational agents (rather than single agents independently).
