Christopher A. Sims, an economist who shared the 2011 Nobel Prize with Thomas J. Sargent for devising statistical tools to guide economic policymakers, has died at 83. Born in Washington D.C., Sims was a professor at Princeton University and made significant contributions to understanding how policy choices affect the economy. His work focused on developing statistical models to help central bankers and policymakers steer the economy, particularly during the stagflation period of the 1970s and ’80s. Sims’ approach emphasized testing economic-policy prescriptions through long-term analysis and warned against relying too heavily on theories, a viewpoint that aligned with his independent views as a Democrat. His legacy in economics will continue to be felt, especially given the ongoing development of artificial intelligence in modeling the economy.
