Pair win Nobel for improving auctions
STOCKHOLM — Auctions are everywhere. They determine how Google sells ads, what price consumers end up paying for electricity, and the way governments sell off the public airwaves to telecom companies and broadcasters.
For helping make auctions run more efficiently, two Americans on Monday won the Nobel prize for economics.
The discoveries of Paul R. Milgrom and Robert B. Wilson, both of Stanford University, “have benefited sellers, buyers and taxpayers around the world,” the Nobel Committee said.
Wilson, 83, was once Milgrom’s Ph.D. adviser, and the two happen to be neighbors. Reached by phone at his home in California, Milgrom, 72, 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.
Security camera footage at Milgrom’s home captured the moment. Wilson knocked on Milgrom’s door in the dead of night and spoke into the intercom. “Paul,’’ he said. “It’s Bob Wilson. You’ve won the Nobel Prize.’’ Awakened, Milgrom stammered and then said: “Wow.’’
The two tackled the tricky problem of making auctions work efficiently. The committee said Wilson’s work showed “why rational bidders tend to place bids below their own best estimate of the common value” — which could mean the item goes for less than it’s worth and perhaps not to the buyer who most wants it, neither of which is supposed to happen if the auction is working properly.
