Nonetheless, some people have argued that carbon pricing is an essential GHG reduction policy, suggesting that sincere politicians must do carbon pricing no matter how politically difficult. But the claim that carbon pricing is essential is factually incorrect. Deep decarbonization can be achieved entirely with regulations. Regulatory policies are unlikely to be as economically efficient as carbon pricing. But not all regulations perform identically when it comes to the economic-efficiency criterion. Flexible regulations have some attributes that make them low cost relative to regulations that require adoption of specific technologies.This talk provides evidence that assesses both the relative economic efficiency of policies and their relative political acceptability. The findings reported here suggest that some kinds of flexible regulations can perform significantly better than explicit carbon pricing in terms of relative political cost per tonne reduced while performing only marginally worse in terms of economic cost per tonne reduced. Presumably, this type of trade-off information could be of value to politicians who sincerely want deep decarbonization but would also like to be rewarded with re-election so that they and competing politicians see the value in ambitious and sustained GHG reduction efforts.

Conference paper, Annual Modeling and Simulation Conference (ANNSIM'25) Abstract The application of Agent-Based Modeling and Simulation (ABMS) has few established guidelines and oftensuffers from insuffdifferent types of model documentation in light of the European Union’s AI Act (AI Act). Our analysisreveals that best practices are often implemented together but ultimately reinforce the pre-existing viewthat ABMS frequently lacks adequate model documentation. This deficiency hinders evaluability, makingit difficult to conduct quality assurance prior to application and meaningful evaluation post application.We propose a framework that highlights the importance of different types of model documentation and theattributes they enable, which are valuable to both modelers and policy actors, albeit for different reasons.The AI Act provides a valuable opportunity to improve model documentation. By proactively developingand establishing guidelines, we can stay ahead of emerging legal requirements.
