Piotr Dworczak presented the paper "Redistributive Allocation Mechanisms" at the Becker Friedman Institute at the University of Chicago. He also covered the applications to vaccine allocation ("An Economic Framework for Vaccine Prioritization") and energy pricing ("A market-design response to the European energy crises"). The audience consisted of the current and former BFI fellows who are mostly not theorists---always exciting to present the IMD agenda to a wider audience!
