Permit Trading and Stability of Climate Agreements
We analyze the implication of different allocation schemes of CO2-emission permits for stability and the success of international climate agreements. Our model combines a game theoretical with an empirical module that comprises 12 world regions and captures important dynamic aspects of the climate change problem. We consider seven different permit allocation schemes. Two “pragmatic schemes” allocate permits according to a uniform emission reductio quota, five “equitable schemes” allocate permits based on some normative criteria frequently discussed in the literature permit trading can raise participation and the success of climate agreements, but pragmatic schemes are superior to equitable ones.
