Robert B. Wilson and Paul R. Milgrom win 2020 Nobel Prize in Economics

  

For their pioneering work in auction theory, Paul R. Milgrom and his doctoral advisor Robert B. Wilson are awarded the most prestigious award of economic sciences, becoming the latest Nobel Laureates in economics.

  • Wilson and Milgrom are honored “for improvements to auction theory and inventions of new auction formats.”
  • Auction theory has many real-world applications, for example government bonds or CO2 emissions allowances.
  • Wilson and Milgrom are both professors at Stanford University in California.
  • Wilson is the doctoral father of three Nobel economists so far, Alvin Roth (2012), Bengt Holmström (2016) and co-Laureate Paul Milgrom (2020).

How do you find out you won the 2020 Nobel prize?

“Paul? It’s Bob Wilson. You won the Nobel Prize.” It was probably the most unusual way economist Paul Milgrom was ever awakened from his sleep. In front of his house was Robert Wilson, his doctoral father and neighbor next door, who had just received the news that he and Milgrom were the 2020 Nobel Laureates in Economic Sciences.

The Nobel Committee had been unable to reach Milgrom because during the night his mobile phone was set not to take calls from unknown numbers.

It’s not known whether the two new Nobel Laureates toasted to their accomplishment after the nightly wake-up call, but they had every reason to do so. Awarded is their fundamental work in the area of auction theory, a sub-area of market design.

Definition: What is Market Design?

Market design deals with the design and analysis of market mechanisms. Its definition of a market is rather broad in the sense that it can include markets in which prices play a role as well as a market for organ donation or choosing between different colleges.

Answer: Market Design.

Wilson and Milgrom, as well as their colleague and friend Alvin Roth, who was awarded the Nobel in 2012, are pioneers in the field of market design.

“Market design is an ancient human activity,” explains Roth. “Market design is about understanding and facilitating that very human process of how we coordinate with other people.”

“The big revolution that market design brings is this notion that the design of the market matters,” adds Milgrom. “It’s not just a matter of people coming together and making whatever trade works. It’s a matter of the market being designed to make that possible.”

“Auctions are everywhere.”

An auction market is a market with competitive bids where an auctioneer comes together with several different bidders. While most people probably think of scenes from movies where expensive jewelry or art goes under the hammer, auction theory has a number of less exquisite but important real-world examples.

“Auctions are everywhere,” said a member of the Nobel Committee at the Prize announcement. CO2 emissions allowances and government bonds are sold on auction markets. Auctions also determine the company that manages home refuse collection, the frequency a mobile provider can offer to customers, or the price that we pay for using electricity.

Fixing real-world problems

The new auction formats developed by Wilson and Milgrom are used across the globe today, after being introduced for the first time in the U.S. in 1994 when radio frequencies were sold to telecom operators in the first radio spectrum auction.

For Milgrom, the real-world application of his work is crucial. “Creating theories that have a direct application more or less immediately and taking problems so directly from the real world, it’s amazing. We’re solving problems and it’s exciting.”

“It’s economic engineering,” adds Roth. “It’s not always simple and it’s not always elegant, but it’s getting things done with the full complexities of the problem.”
