William D. Nordhaus, PhD ’67, a scholar known for his work on the long-term interaction of climate change and the economy, will share the 2018 Nobel Prize in economic sciences with Paul M. Romer of New York University’s Stern School of Business, who also did graduate work at MIT. The Royal Swedish Academy of Sciences announced that the two economists have “significantly broadened the scope of economic analysis by constructing models that explain how the market economy interacts with nature and knowledge.”
In Nordhaus’s case, the academy cited his pioneering development of an “integrated assessment model” representing “the global interplay between the economy and the climate.” Nordhaus has refined multiple iterations of his model. He has also written about climate and economics for a broad audience as the author of several books.
Nordhaus, who is a professor of economics at Yale University, completed his PhD dissertation at MIT under the supervision of Robert M. Solow, himself the 1987 winner of the economics Nobel. Multiple winners of this award, including Peter Diamond, George Akerlof, and Joseph Stiglitz, have also had Solow as their principal advisor in MIT’s graduate program. Additionally, MIT biology professor H. Robert Horvitz ’68, a Nobel laureate in 2002 in the category of Physiology or Medicine, wrote his undergraduate thesis in economics under the direction of Solow.
