SUMMARY:CERNA Research Seminar will welcome Nicolas Schutz (Mannheim)
DESCRIPTION:We are pleased to announce that Nicolas Schutz (Mannheim) will be the next speaker in our CERNA Research Seminar. The seminar will take place on Tuesday\, April 15\, 2025\, at 12 AM in Salle Vendôme. \n\nNicolas will present his paper: \n  \nOligopoly\, Complementarities\, and Transformed Potentials \n(joint with Volker Nocke) \n  \nWe adopt a potential games approach to study multiproduct-firm pricing games where products can be local complements or substitutes. We show that any such game based on an IIA demand system admits an ordinal potential\, giving rise to a simple proof of equilibrium existence. We introduce the concept of transformed potential\, and characterize the class of demand systems that give rise to multiproduct-firm pricing games admitting such a potential\, as well as the associated transformation functions. The resulting demand systems allow for substitutability or complementarity patterns that go beyond IIA\, and can resemble those induced by “one-stop shopping” behavior. \n  \nThe paper Nicolas will present is below in case you want to have a look at it in advance. \nPaper of  Nicolas Schutz-Jan2025 \n
