William Nordhaus is an American economist renowned for pioneering the integration of climate change into long-run macroeconomic analysis. A Sterling Professor of Economics at Yale University, his development of quantitative models that assess the interplay between the economy and the climate has fundamentally shaped global environmental policy. He was jointly awarded the Nobel Memorial Prize in Economic Sciences in 2018 for modeling the greenhouse effect within economic frameworks.

Early life and education

Born in Albuquerque, New Mexico, Nordhaus grew up in a family with strong academic ties, including his brother, the noted physicist Robert Nordhaus. He completed his undergraduate studies at Yale University, earning a Bachelor of Arts degree in 1963. He then pursued graduate work at the Massachusetts Institute of Technology, where he studied under future Nobel laureate Robert Solow. Nordhaus received his Ph.D. in Economics from MIT in 1967, with a dissertation that explored theories of economic growth and technological change.

Academic career

Nordhaus began his long-standing affiliation with Yale University immediately after completing his doctorate, joining its faculty in 1967. He has held numerous prestigious positions there, including serving as the Provost of the university from 1986 to 1988. He is a longtime associate of the Cowles Foundation for Research in Economics at Yale and has been a research associate at the National Bureau of Economic Research for decades. His academic work has spanned macroeconomics, productivity, and the economics of technological change, but he is most celebrated for his later environmental contributions.

Contributions to climate change economics

Nordhaus's most influential work began in the 1990s with the creation of the Dynamic Integrated model of Climate and the Economy (DICE) and its regional counterpart, the Regional Integrated model of Climate and the Economy (RICE). These integrated assessment models were the first to combine basic economic principles with geophysical science from fields like climatology and chemistry. The models simulate the global costs and benefits of reducing carbon dioxide emissions, providing a framework for calculating an optimal carbon price or carbon tax. His research has been central to debates at institutions like the Intergovernmental Panel on Climate Change and informed international agreements such as the Paris Agreement.

Nobel Memorial Prize in Economic Sciences

In 2018, Nordhaus was awarded the Nobel Memorial Prize in Economic Sciences, sharing the honor with Paul Romer for his work on endogenous growth theory. The Royal Swedish Academy of Sciences specifically cited Nordhaus for "integrating climate change into long-run macroeconomic analysis." His modeling work provided the tools to analyze how economic activity causes climate change and to design policy remedies like carbon pricing. The award solidified his status as a foundational figure in the field of environmental economics.

Other research and policy work

Beyond climate economics, Nordhaus has made significant contributions to other areas. He served as a member of the President's Council of Economic Advisers under President Jimmy Carter from 1977 to 1979. His research has also delved into the economics of health care, the measurement of economic welfare, and the "Nordhaus effect" related to political business cycles. He has been a prolific author, co-authoring the influential textbook Economics with Paul Samuelson for many editions and publishing in leading journals like the American Economic Review.

Personal life and legacy

Nordhaus is married to Barbara Nordhaus, and they have one child. His legacy is defined by transforming climate change from a purely scientific concern into a central question of economic policy and welfare. His models remain critical tools for governments, the United Nations, and researchers worldwide. He continues to be an active scholar and advocate for evidence-based climate policy, influencing generations of economists at Yale University and beyond.
