Paul R. Milgrom shared the 2020 Nobel Prize in Economics for improvements to auction theory and inventions of new auction formats.
Milgrom studied how auction rules affect bidding behavior, prices, and the allocation of resources. His work addressed situations in which bidders value items differently and may possess related information about their potential worth.
He and Robert B. Wilson developed auction theory and helped design formats used in practice. Milgrom’s work included the simultaneous multiple-round auction, which was created to sell combinations of related licenses while allowing bidders to respond to changing information.
The prize recognized both theoretical advances and practical market design. Auctions are used for spectrum licenses, electricity, advertisements, financial assets, and many other goods. The 2020 award is distinct from the 2012 prize for market-matching systems associated with Alvin Roth and Lloyd Shapley.
