We analyze a two-stage coalition formation game in which the provision of the global public good is not only associated with variable costs but also with fixed costs. We consider the assumptions that signatories share or do not share fixed costs. We show that fixed costs may imply corner...

Abstract We analyze how geoengineering in the form of solar radiation management (SRM), associated with the potential of high collateral damages, affects the governance architecture of climate agreements. We investigate under which conditions signatories to a climate agreement can avoid the...

Solar radiation management (SRM), as one form of geoengineering, has been proposed as a last exit strategy to address global warming. Even though SRM is expected to be cheap, it may be risky and associated with high collateral damages. We analyze how SRM affects equilibrium mitigation...

We analyze how geoengineering, associated with a high risk of collateral damages, affects the governance architecture of climate agreements. We clarify under which conditions signatories to a climate agreement can avoid that non-signatories deploy risky geoengineering. We correct and qualify the...
