STOCKHOLM: Two American economists won the Nobel Prize for improving how auctions work, research that underlies much of todays economy from the way Google sells advertising to the way telecoms companies acquire airwaves from the government.
The discoveries of Paul R. Milgrom and Robert B. Wilson, both of Stanford University, have benefitted sellers, buyers and taxpayers around the world, the Nobel Committee said.
Wilson was once Milgrom’s Ph.D. adviser, and the two also happen to be neighbors. Reached by phone at his home in California, Milgrom said he received news of their win in a strange way.
I got a knock at my door from Bob Wilson, he told The Associated Press.
Milgrom, 72, said students, friends and colleagues had long suggested he and Wilson, 83, might be due for the prize.
“Its nice to have their respect but their affection as well, he said.
Technically known as the Sveriges Riksbank Prize in Economic Sciences in Memory of Alfred Nobel, the award was established in 1969 and is now widely considered one of the Nobel prizes.
The two men tackled the tricky problem of making auctions work efficiently. The committee said Wilsons work showed why rational bidders tend to place bids below their own best estimate of the common value.
The effects of their work can be seen all around. Online advertising is sold at auction,” said David Warsh, who tracks economic research at his blog Economic Principals. That Google was able to adopt the method so quickly and seamlessly depended entirely on theory developed by Milgrom and his competitors and their students.”
The work is about more than money. Some governments, for example, auction off the right to pollute in hopes of reducing emissions; cleaner companies can resell unneeded rights to dirtier ones, creating a financial incentive for companies to make their operations greener. The objective is not always to maximize the revenue for the seller but also can have a societal objective,” said Nobel Committee member Ingrid Werner.
One problem in auctions is the so-called winner’s curse. If buyers are vying to purchase, say, fishing rights, they have to make bids without knowing what the price of fish will be in the future. They begin to worry that they will only prevail by overpaying, and they can respond by scaling back their offers. The problem is especially acute when some bidders have more information than others.
A solution to the curse, Wilson and Milgroms research showed, is for the seller to provide as much information as possible before the bidding begins, perhaps providing an independent appraisal of the value of the item being sold.
They also tackled the snake in the grass strategy, Wilson said. This involves a company keeping its interest in the item being sold secret for most of the auction and then making the winning bid at the last minute.
Its like sniping an eBay auction, Wilson told the AP, adding that they designed rules that force bidders to reveal their interest earlier on.
Their research has had a big impact on the telecommunications industry, where private companies seek licenses from the government to use publicly owned radio frequencies for everything from mobile phone calls to internet payments.
Before the 1990s, the U.S. government essentially conducted beauty contests to hand out the frequencies, letting companies make their case for getting the licenses. The approach encouraged aggressive lobbying but didnt raise much money for the Treasury.
In 1994, the U.S. government turned to auctions. Milgrom and Wilson (with help from Preston McAfee, now at Google) designed an auction format in which all the licenses were sold in one go. That format discourages speculators from buying up frequencies in a specific geographic area and then reselling them to big telecommunications companies seeking to patch together national or regional networks.
The auction raised $617 million selling frequencies that previously were handed out for virtually nothing and became a model for countries from Canada to India. The format has also been used to auction off electricity and natural gas.
Wilson said that he thought the time for winning a Nobel Prize had already passed.
Speaking to reporters in Stockholm by phone after learning of his win, Wilson struggled to think of a recent auction he himself had participated in. But then added: My wife points out to me that we bought ski boots on eBay.
Wilson described Milgrom as sort of the genius behind all of this auction work. Milgrom developed a more general theory of auctions.
Americans have figured prominently among this years Nobel winners. Leaving aside the peace prize, which went to the U.N.s World Food Program, seven of the 11 laureates have been Americans.
Goran Hansson, secretary-general of the Royal Swedish Academy of Sciences who announced the award, said that reflected American investment in research after WWII. And well see how that trend may change,” he added.
Last years award went to two researchers from the Massachusetts Institute of Technology and a third from Harvard University, for research into efforts to reduce global poverty.
The award comes at a time of dramatic economic upheaval that few economists could have predicted last fall: In the face of the coronavirus pandemic, governments have closed borders, imposed lockdowns and ordered other measures, triggering a sharp dip in business activity.
Wilson said that, given the ongoing pandemic, he had no immediate plans for what to do with his share of the the 10-million krona ($1.1 million) cash prize that comes with the award, along with a gold medal.
Probably Ill just save it for my wife, my children, he said.
Last week, the Nobel Committee awarded the prize for physiology and medicine for discovering the liver-ravaging hepatitis C virus. The prize for physics honored breakthroughs in understanding black holes, and the chemistry prize went to scientists behind a powerful gene-editing tool.
The literature prize was awarded to American poet Louise Glck. The World Food Program won the peace prize for its effort to combat hunger.
