The Defense Advanced Research Projects Agency (DARPA) is seeking insights through a Request for Information (RFI) titled "Geoeconomic Modeling for National Security." The RFI aims to gather information on the current state of geoeconomic modeling, focusing on the capabilities and limitations of existing models, the availability and quality of data used for calibration, and best practices for user interaction with these models to enhance decision-making in national security contexts. Accurate geoeconomic models are crucial for understanding the impacts of economic policies and technology on global dynamics, including predicting the effects of economic sanctions and identifying potential conflict triggers. Responses to the RFI are due by October 15, 2024, and interested parties can contact the RFI Coordinator at DARPA via email at DARPA-SN-24-104@darpa.mil for further information.
