Sustainability of Cooperation in Dynamic Games Played over Event Trees
Georges Zaccour (École des Hautes Études commerciales de Montréal)
A well-known problem in dynamic cooperative games is the sustainability of cooperation over time. The literature addressed this issue following different approaches, namely, the design of time-consistent payments, incentive equilibrium strategies and trigger strategies that deter credibly and effectively deviation from cooperation. In this talk, I will apply these different approaches to dynamic games played over event trees, that is, stochastic games where the uncertainty is not influenced by players' actions but it is nature's decision. After introducing the main elements of this class of games, I will introduce node-consistent cooperative payments based on the Shapley value and imputations in the core as means for sustaining cooperation over nodes (and time). Further, I will show how incentive and trigger strategies can be constructed to strategically support the cooperative agreement designed at the starting date of the game.
