Improving accuracy, complexity and policy relevance: a literature survey on recent advancements of climate mitigation modeling by Chen Chris Gong, Behnaz Minooei Fard, Ibrahim Tahri

“…ABM highlights the decision-making processes and behaviors of heterogeneous agents, while game theory examines market dynamics, such as newcomer vs. incumbent competition, strategic pricing, and resource extraction. While these models cannot replace IAMs, they can broaden the scenario design space and improve the complexity and policy relevance of IAM-based mitigation modeling.…”
