On May 12-14, Tim Büthe, associate professor of political science and public policy, attended the lead authors' meeting in Geneva for "Varieties of Global Governance," chapter 12 of "Rethinking Society for the 21st Century", the report of the International Panel on Social Progress (IPSP). The IPSP is tasked to harness insights from across the social sciences to develop "research-based, multi-disciplinary, non-partisan, action-driven solutions to the most pressing challenges of our time." The only political scientist among the multi-disciplinary panel on global governance (and one of two Duke faculty among the 250 lead authors for the IPSP), Büthe was appointed at the recommendation of the IPSP advisory committee, led by Harvard economist Amartya Sen, and the IPSP Steering Committee, spearheaded by Princeton's Marc Fleurbaey.
