The junior seminar aims at gathering PhD students and post-docs whose research topics deal with game theory in a broad sense. During the seminar, the participants may present their works, advanced or in progress, to their peers. They may also present articles they believe are interesting (in a journal club fashion). They can be theoretical economists, mathematicians, and computer scientists. The seminar will take place around every two weeks on Mondays, 10am, before the senior game theory seminar. Participants who want to be speakers are most welcome and should contact the organizers.
The next issue is on January 12th, 10am at the IHP (room 201).
Diego San Roman will present his work "Multiplexed Network Formation".
Abstract: We study a non-cooperative game in which individuals participate in multiple costly activities they have preferences over, and choose how much of their limited time to spend on each activity. This gives rise to an endogenously formed, weighted multiplexed network. We first give a rationale for multiplexed networks. We then show that agents are better off when preferences, costs and strategic complementarity parameters are heterogeneous, than when they are homogeneous across activities. We furthermore provide comparative statics on welfare, and find that, when costs of performing activities are sufficiently large, only multiplexed networks maximize welfare. We finally show that utility, which is increasing in Bonacich centrality in simplex networks, is not necessarily so in multiplexed networks.
