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…
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…
Two Margins of Climate Cooperation: Emissions and Coalition Membership under Tipping
Lei Zhu, Zhihao Yan, Yaofeng Cui +3
We study climate coalition stability with endogenous temperature and stochastic tipping. In our dynamic game, rising temperature widens the emissions gap between members and nonmem…
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…
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…
The Social Cost of Carbon with Economic and Climate Risks
Yongyang Cai, Kenneth L. Judd, Thomas S. Lontzek
There is great uncertainty about future climate conditions and the appropriate policies for managing interactions between the climate and the economy. We develop a multidimensional…
