最优环境政策的设计继承了模型的不确定性。我们在一个简单的线性模型中研究了这些后果,其中决策者的目标是稳定大气中的碳含量。我们使用汉森和萨金特(2003,2008)的方法研究决策者对稳健性的关注如何改变政策。分析表明,政策制定者,谁担心模型的错误设定,应该更积极地应对大气碳储量的变化,并减少排放量更强。
The design of optimal environmental policy inherits model uncertainty. We investigate the consequences in a simple linear model, where the aim of the policymaker is to stabilise the atmospheric content of carbon. We study how decision-makers’ concerns about robustness alters policy using the Hansen and Sargent (2003, 2008) approach. The analysis shows that a policymaker, who fears about model misspecification should react more aggressively to changes in the stock of atmospheric carbon and reduce emissions stronger.
