Robert Wilson and Paul Milgrom won the 2020 Sveriges Riksbank Prize in Economic Sciences on Monday. What followed after shows the excitement and camaraderie the two Stanford University professors share. The 72-year old Milgrom was informed about winning the prize by his 83-year old co-winner Wilson by a 2:15 am knock at the former’s door.

Incidentally, they live on the same street.

The exact moment of Wilson telling his neighbour about their achievement was captured on a security camera and was shared by Stanford University.

“Paul,” Wilson calls, knocking on the door.

“Paul, it’s Bob Wilson,” he says.

“You won the… you won the Nobel Prize,” he continued.

“And so, they’re trying to reach you, but they cannot. They don’t seem to have a number for you.”

“We gave them your cellphone number,” says Mr Wilson’s wife.

“Yeah, I have? Wow,” Mr Milgrom could be heard saying.

“Will you answer your phone?” Mr Wilson’s wife asks.

When Milgrom was informed, his wife was in Stockholm, the University said. She received a security-camera notification on her phone and watched live when Wilson told her husband that he had won the Nobel Prize.

The video has been watched over 3.3 million times and retweeted over 25.3K times.

Milgrom and Wilson won the Nobel for work on commercial auctions, including for goods and services difficult to sell in traditional ways such as radio frequencies, the Nobel Committee said.

The Royal Swedish Academy of Sciences noted that the discoveries by the duo “have benefitted sellers, buyers, and taxpayers around the world,” it said in a statement.

The winners will share the prize sum of 10 million Swedish kronor (about $1.1 million)
