Three US-based economists have won the 2021 Nobel Prize for Economics for work on drawing conclusions from unexpected experiments, or so-called “natural experiments”.
The winner was David Card of the University of California at Berkeley; Joshua Angrist from the Massachusetts Institute of Technology; and Guido Imbens from Stanford University.
