Solving Nash Equilibria in Nonlinear Differential Games for Common-Pool Resources
Yongyang Cai, Anastasios Xepapadeas, Aart de Zeeuw
Many resources are provided by an ecological system that is vulnerable to tipping when exceeding a certain level of pollution, with a sudden big loss of ecosystem services. An ecol…
Concentrated siting of AI data centers drives regional power-system stress under rising global compute demand
Danbo Chen, Zijun Zhou, Yongyang Cai +3
The rapid rise of generative artificial intelligence (AI) is driving unprecedented growth in global computational demand, placing increasing pressure on electricity systems. This s…
Dynamics of Global Emission Permit Prices and Regional Social Cost of Carbon under Noncooperation
Yongyang Cai, Khyati Malik, Hyeseon Shin
We develop a dynamic multi-region climate-economy model with emissions trading and solve for the dynamic Nash equilibrium under noncooperation, where each region follows Paris Agre…
Modeling Uncertainty in Integrated Assessment Models
Yongyang Cai
Integrated Assessment Models (IAMs) are pivotal tools that synthesize knowledge from climate science, economics, and policy to evaluate the interactions between human activities an…
Long Coalition Leads to Shrink? The Roles of Tipping and Technology-Sharing in Climate Clubs
Lei Zhu, Zhihao Yan, Hongbo Duan +2
Global cooperation is posited as a pivotal solution to address climate change, yet significant barriers, like free-riding, hinder its realization. This paper develops a dynamic gam…
