Nobel for climate change economists

Nobel for climate change economists


American economists William Nordhaus and Paul Romer, pioneers in adapting economic theory to take better account of environmental issues and technological progress, shared the 2018 Nobel Economics Prize on Monday.

In an award that turned the spotlight on the global debate on climate change, the Royal Swedish Academy of Sciences said the laureates’ work helped answer fundamental questions on how to promote long-term sustainable growth and enhance human welfare.

The prize took Dr. Romer, of New York University’s Stern School of Business, by surprise. 'I got two phone calls this morning, and I didn’t answer either one because I thought it was some spam call, so I wasn’t expecting the prize,' he said.

'I think ... many people think that protecting the environment will be so costly and so hard that they just want to ignore (this)...,' he said.

'(But) we can absolutely make substantial progress protecting the environment and do it without giving up the chance to sustain growth.'

Dr. Romer had shown how economic forces govern the willingness of firms to produce new ideas and innovations, laying the foundations for a new model for development, known as endogenous growth theory.

Dr. Nordhaus, of Yale University, was the first person to create a quantitative model that described the interplay between the economy and the climate.

'Their findings have significantly broadened the scope of economic analysis by constructing models that explain how the market economy interacts with nature and knowledge,' the academy said in statement.

Hours before the award, the United Nations panel on climate changed warned of the risks of more frequent heat waves, floods and drought in some regions as well as the loss of species without a radical rethink in how societies operate.

Monday’s award also took place less than a month after the 10th anniversary of the collapse of investment bank Lehman Brothers. That triggered an economic crisis from which the world’s financial system is arguably still recovering.

The Nobel prizes for physiology or medicine, physics, chemistry and peace were awarded last week. The proceedings have been overshadowed by the absence of the literature prize, postponed to give the Swedish Academy time to restore public trust after a sexual assault scandal.
