异质信念下的气候变化适应
Climate Change Adaptation under Heterogeneous Beliefs
摘要：
我们研究了对未来气候影响有异质信念的企业之间的战略互动。为此，我们提出了一个古诺型均衡模型，企业选择缓解努力和生产数量，如在他们的主观信念，以最大限度地提高预期利润。它表明，最佳的缓解努力增加了不确定性的存在，并作为替代品;即，一家公司不采取缓解措施会激励其他公司采取更果断的行动，反之亦然。
英文摘要：
We study strategic interactions between firms with heterogeneous beliefs about future climate impacts. To that end, we propose a Cournot-type equilibrium model where firms choose mitigation efforts and production quantities such as to maximize the expected profits under their subjective beliefs. It is shown that optimal mitigation efforts are increased by the presence of uncertainty and act as substitutes; i.e., one firm's lack of mitigation incentivizes others to act more decidedly, and vice versa.
