Aus der Einleitung:

In the following this paper explores how a global climate constitution may emerge as a sequence of accessions given that, in each round of negotiations, sovereign states are free to join or to maintain their independence. The aim is to unveil the determinants of the progress towards a global climate constitution. To that aim we study a sequential game (with myopic players). The game is introduced in the next section. Section 3 discusses how the game is solved. Section 4 provides simulation results that illustrate the findings. Section 5 draws conclusions for climate policies.
