Long-time NBER research associates Joshua Angrist , David Card , and Guido Imbens have been awarded the 2021 Nobel Prize in Economic Sciences in recognition of their contributions to labor economics and the analysis of natural experiments.
In announcing the prize, the Royal Swedish Academy of Sciences explained that “Card’s studies of core questions for society, and Angrist and Imbens’ methodological contributions, have shown that natural experiments are a rich source of knowledge. Their research has substantially improved our ability to answer key causal questions, which has been of great benefit to society.”
Angrist is the Ford Professor of Economics at MIT, Card is the Class of 1950 Professor of Economics at the University of California, Berkeley, and Imbens is the Applied Econometrics Professor and Professor of Economics at the Stanford University Graduate School of Business. All three are affiliated with the NBER Labor Studies Program, which Card directed for nearly a decade. Angrist and Card are also affiliated with the NBER programs on Children and Education, and Card with the Economics of Aging program.
The laureates delivered their prize lectures on December 8, 2021.
