Dear all,
you are all invited to participate to the following seminar on *Tuesday 23th of January 2023 at 16:00* in Aula Seminari Demografica 2062 at University of Milano Bicocca (via degli Arcimboldi 8, Milano - building U7, 2nd floor):
Speaker: *Alessandro Doldi* (University of Florence)
Titolo: *Collective Arbitrage and the Value of Cooperation*
Abstract: The paper aims at extending the classical Arbitrage Pricing Theory to a scenario where N agents engage in financial market investments and are permitted to collaborate through exchanges. Within this framework, we introduce the concepts of Collective Arbitrage and Collective Super-replication. Subsequently, we establish versions of the fundamental theorem of asset pricing and the pricing-hedging duality tailored to this cooperative setting. Illustrative examples demonstrate the advantages of our proposed approach. The novel notions of Collective Arbitrage and Collective Super-replication highlight the pivotal role of cooperation and the multidimensional aspect. Notably, when there is only a single agent involved, the theory reduces to the classical one.
Best wishes,
Emanuela
