Dynamics of Hierarchical Coalition Formation — •Jobst Heitzig — Potsdam Institute for Climate Impact Research

In many situations of strategic interaction of many agents, complex coalition structures can form, and the question which coalitions will form can have considerable consequences, as is obvious from the ongoing international climate negotiations. Still, the dynamical process of coalition formation by boundedly rational agents is only understood quite rudimentary yet. We present first results of a new dynamical model of coalition formation that allows for hierarchical coalition structures (coalitions of coalitions). In particular, we argue that the possibility of first forming small regional coalitions and then forming an overarching global coalition later might increase the prospects of efficient climate mitigation.
