Environmental Agreements under Asymmetric Information
研究在减排成本为私人信息且参与自愿的情况下，谈判前阶段作为信息共享和认证机制能否恢复高效环境协议的可行性。
In a two-country model, I investigate the role of a pre-negotiation phase as an information-sharing and certification device to restore the feasibility of an efficient environmental agreement when countries’ abatement costs are private information and participation is voluntary. When uncertainty regarding abatement costs is high, the welfare gains of reducing information asymmetries and reaching the first-best agreement will be sufficiently large to design budget-balanced transfers that compensate both countries for the loss of the information rent they could obtain by staying privately informed. Both countries then accept to share and certify their abatement costs during the pre-negotiation phase.
