Keeping Negotiations in the Dark: Environmental Agreements under Incomplete Information
This paper investigates the role of uncertainty as a tool to support cooperation in international environmental agreements. We consider two layers of uncertainty. Under unilateral uncertainty treaties become successful with positive probability in the signaling game, even under parameter conditions for which no agreement is reached under complete information. Under bilateral uncertainty, a separating equilibrium emerges where the leader participates in the treaty only when its environmental concerns are high. We show that the agreement is signed for larger sets of parameter values under unilateral uncertainty. We then show that further layers of uncertainty might enhance social welfare.
