We conduct a sensitivity analysis of a new type of integrated climate-economic model recently proposed in the literature, where the core economic component is based on the Goodwin--Keen dynamics instead of a neoclassical growth model. Because these models can exhibit much richer behavior, including multiple equilibria, runaway trajectories, and unbounded oscillations, it is crucial to determine their sensitivity to changes in underlying parameters. We focus on four economic parameters (markup rate, speed of price adjustments, coefficient of money illusion, growth rate of productivity) and two climate parameters (size of upper ocean reservoir, equilibrium climate sensitivity) and show how their relative effects on the outcomes of the model can be quantified by methods that can be applied to an arbitrary number of parameters.

短讯：综合气候经济模型的敏感性分析

SIAM 金融数学杂志，第 12 卷，第 2 期，第 SC-44-SC-57 页，2021 年 1 月。
我们对文献中最近提出的一种新型综合气候经济模型进行了敏感性分析，其中核心经济组成部分基于 Goodwin--Keen 动力学而不是新古典增长模型。由于这些模型可以表现出更丰富的行为，包括多重平衡、失控轨迹和无界振荡，因此确定它们对基础参数变化的敏感性至关重要。我们关注四个经济参数（加价率、价格调整速度、货币错觉系数、生产力增长率）和两个气候参数（上层海洋水库的规模、平衡气候敏感性），并展示它们对结果的相对影响。该模型可以通过可应用于任意数量参数的方法进行量化。
