American duo wins Nobel for economics
AMERICANS William Nordhaus and Paul Romer, pioneers in adapting the Western economic growth model to focus on environmental issues and sharing the benefits of technology, won the 2018 Nobel Economics Prize yesterday.
In a joint award that turned the spotlight on a rapidly shifting global debate over the impact of climate change, the Royal Swedish Academy of Sciences said the duo’s work was helping to answer basic questions over how to promote long-term, sustainable prosperity.
Romer, of New York University’s Stern School of Business and best known for his work on endogenous growth — a theory rooted in investing in knowledge and human capital — said he had been taken by surprise by the award, but offered a positive message.
“I think one of the problems with the current situation is that many people think that protecting (the) environment will be so costly and so hard that they just want to ignore them,” he said.
“We can absolutely make substantial progress protecting the environment and do it without giving up the chance to sustain growth.”
Hours before the award, the United Nations panel on climate change said society would have to radically alter the way it consumes energy, travels and builds to avoid the worst effects of global warming.
The panel declined to comment on yesterday’s award.
US President Donald Trump has repeatedly called climate change a hoax, and last year announced that he would withdraw the United States from a global pact to combat it reached in 2015, calling the deal’s demands for emissions cuts too costly.
Nordhaus, a professor of economics at Yale University, was the first person to create a quantitative model that described the interplay between the economy and the climate, the Swedish academy said.
“The key insight of my work was to put a price on carbon in order to hold back climate change,” Nordhaus was quoted as saying in a Yale publication this year. “The main recipe ... is to make sure governments, corporations and households face a high price on their carbon emissions.”
Nobel committee chair Per Stromberg said yesterday’s award was honoring research into two big global questions: how to deal with the negative effects of growth on the climate and “to make sure that this economic growth leaves prosperity for everyone.”
Romer had shown how economic forces govern the willingness of firms to innovate, helping some societies grow many times faster than others. By understanding which market conditions favor the creation of profitable technologies, society can tailor policies to promote growth, the academy said.
Romer’s career has taken him outside the academic world. While on leave from the Stern School, he served as chief economist and senior vice president at the World Bank until early this year.
His work on endogenous growth theory is not universally admired.
Fellow Nobel economics Laureate Paul Krugman told the New York Times in 2013 that too much of it involved “making assumptions about how unmeasurable things affected other unmeasurable things.”
