Nobel Prize for three US-based economists

Current GK ( Master) Awards

Three US-based economists won the 2021 Nobel Prize for economics on Monday for pioneering research on the labour market impacts of minimum wage, immigration and education, and for creating the scientific framework to allow conclusions to be drawn from such studies that can’t use traditional methodology.
Canada-born David Card of the University of California at Berkeley was awarded one half of the prize, while the other half was shared by Joshua Angrist from the Massachusetts Institute of Technology and the Netherlands-born, Guido Imbens, 58, from Stanford University.
“Card’s studies of core questions for society and Angrist and Imbens' methodological contributions have shown that natural experiments are a rich source of knowlege,” said Peter Fredriksson, chair of the Economic Sciences Committee. “Their research has substantially improved our ability to answer key causal questions, which has been of great benefit for society.” Card worked on research that used restaurants in New Jersey and in eastern Pennsylvania to measure the effects of increasing the minimum wage.
He and his late research partner Alan Krueger found that an increase in the hourly minimum wage did not affect employment, challenging conventional wisdom.
