Americans share distinction for insights on climate, tech
Two Americans won the Nobel Prize in economics on Monday, one for studying the economics of climate change and the other for showing how to help foster the innovation needed to solve such a problem.
William Nordhaus of Yale University and Paul Romer of New York University will share the 9 million-kronor ($1.01 million) award, the Royal Swedish Academy of Sciences said.
Nordhaus has called for the world to combat climate change by imposing a universal tax on carbon. Carbon dioxide, which is emitted when fossil fuels are burned, is a heat-trapping “greenhouse gas” blamed for global warming, and a tax would make polluters pay for the costs imposed on society.
By using a tax rather than government edicts to slash emissions, the policy encourages companies to find innovative ways to reduce pollution.
Romer has studied the way innovation drives prosperity and has looked at ways to encourage it. He told a news conference Monday that his research had given him hope that people can solve a problem even as difficult as a warming planet.
“Many people think that dealing with protecting the environment will be so costly and so hard that they just want to ignore the problem. They want to deny it exists,” Romer said. “I hope the prize today could help everyone see that humans are capable of amazing accomplishments when we set about trying to do something.”
While the two academics worked separately, their research dovetails on an issue that has become pressing. The question of climate change remains politically sensitive, especially in big oil-producing countries like the United States, which President Trump has pulled out of the Paris accord on fighting climate change.
“It’s an ingenious pairing,” said David Warsh, author of the 2007 book “Knowledge and the Wealth of Nations” about the award. “Nordhaus has been concerned all along with repairing the damage” to the global environment. “Romer has been writing about the means at your disposal” to attack such a technological challenge.
Per Stromberg, head of the Nobel economics prize committee, said the award is “about the longrun future of the world economy.”
The prize comes just a day after an international panel of scientists warned that preventing an extra single degree of global warming could make a life-or-death difference in the next few decades for multitudes of people and ecosystems.
Nordhaus has argued that climate change should be considered a “global public good,” like public health and international trade, and regulated accordingly, but not through a command-and-control approach. Instead, by agreeing on a global price for burning carbon that reflects its whole cost, this primary cause of rising temperatures could be traded and taxed, putting market forces to work on the problem.
The economics prize is the last of the Nobels to be announced this year.
