在模拟创新对边际减排成本（MAC）曲线的影响时，环境经济学的许多研究都隐含或明确地假设了一致的向下移动。本文的目的是彻底调查这一主张在一个简单的理论框架，通过引入创新的价格，污染企业的生产函数在四个经济上有意义的方式。我们建立的MAC曲线上的创新的影响，关键取决于特定类型的创新，只有在终端的管道技术的创新导致MAC曲线的均匀下移。第二类结果表明，对于整个生产过程中的其他类型的创新，MAC曲线响应创新向上移动的范围在理论上更容易证明。这些结果要求重新评估的各种结果，在环境政策中获得的理论工作依赖于这一假设。
When modeling the effects of innovation on the marginal abatement cost (MAC) curve, many studies in environmental economics have posited, implicitly or explicitly, a uniform downward shift. The purpose of this paper is to thoroughly investigate this claim in a simple theoretical framework by introducing innovation in the production function of a price-taking, polluting firm in four economically meaningful ways. We establish that the effects of innovation on the MAC curve depend critically on the specific type of innovation, and that only innovation in end-of-pipe technology leads to a uniform downward shift of the MAC curve. A second class of results points to the fact that for other types of innovation in the overall production process, the scope for an upward shift of the MAC curve in response to innovation is easier to justify theoretically. These results call for a re-appraisal of various results in environmental policy obtained in theoretical work relying on this postulate.
