Negotiating Upstream-Downstream Environmental Agreements

We consider the outcomes of two versions of the “Bargain with your neighbors” protocol for two upstream-downstream games: the Seawall game (Delille and Pereau [2014]) and the Great Lakes game (Becker and Easter [1999]).

Resumo:We consider the outcomes of two versions of the “Bargain with your neighbors” protocol for two upstream-downstream games: the Seawall game (Delille and Pereau [2014]) and the Great Lakes game (Becker and Easter [1999]). In such a protocol, bilateral bargaining takes place with the players that are located immediately upstream or downstream (neighbors). While in the first version players bargain over actions and transfers simultaneously, in the second version players commit to an action if the subsequent negotiation over transfers is successful. We obtain different outcomes depending on the players’ beliefs about what happens when there is disagreement at one bargaining. The socially optimal outcome is obtained when players pre-commit actions and bargain over transfers in the case where one disagreement implies global disagreement. This implies that the institutional rule of the Great Lakes granting veto power to all its members is a necessary condition to reach socially optimal outcomes.
