Mattauch et al.(2020)声称，Lemoine和Rudik(2017)中的定量结论--此后称为LR17--对于使用与最近的科学结果一致的气候模型并不可靠。我们观察到，LR17实际上分析了一个更现实的碳模型的扩展，该模型产生了一个非常类似于Mattauch等人的有效排放税轨迹。(2020)，我们在这里表明，LR17温度模型的简化不会定性地影响他们的政策结论。计入惯性后，初始排污税减少42%，减排成本现值减少39%。(JEL H23、Q54、Q58)
Mattauch et al. (2020) claims that the quantitative conclusions in Lemoine and Rudik (2017)—henceforth, LR17—are not robust to using a climate model consistent with recent scientific results. We observe that LR17 in fact analyzes an extension to a more realistic carbon model that generates an efficient emission tax trajectory very similar to that in Mattauch et al. (2020), and we here show that simplifications in the temperature model of LR17 do not qualitatively affect their policy conclusions. Accounting for inertia reduces the initial emission tax by 42 percent and reduces the present value of abatement cost by 39 percent. (JEL H23, Q54, Q58)
