This essay critiques the Ramsey model, highlighting shortcomings in it and describing how to go beyond it towards more nuanced assessments through more accurate utility approximation and more diverse climate change mitigation strategies. This essay also critiques the 2 popular approaches for defining the model’s ethics, prescriptivism and descriptivism, both in and beyond the Ramsey model context. The descriptive approach is found to hold serious flaws and should be rejected. Despite the model’s various shortcomings, the climate change assessments using it provide a valuable applied ethics tool and bolster the case for climate change mitigation.
