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.
Canadian-born David Card of the University of California, Berkeley, was awarded one half of the prize for his research on how minimum wage, immigration and education affect the labour market, while the other half was shared by Joshua Angrist from the Massachusetts Institute of Technology and Dutch-born Guido Imbens from Stanford University for their framework for studying issues that can't rely on traditional scientific methods.
The Royal Swedish Academy of Sciences said the three have completely reshaped empirical work in the economic sciences.
The prize, formally known as the Sveriges Riksbank Prize in Economic Sciences in Memory of Alfred Nobel, is the last of this year's crop of Nobels and sees the winners share a sum of 10 million Swedish crowns (USD 1.14 million).
Cards studies of core questions for society and Angrist and Imbens methodological contributions have shown that natural experiments are a rich source of knowledge, 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 studied what happened when New Jersey raised its minimum wage from USD 4.25 to USD 5.05, using restaurants in bordering eastern Pennsylvania as a comparison group.
Contrary to previous studies, he and his late research partner Alan Krueger found that an increase in the minimum wage had no effect on the number of employees. Card later did further work on the issue. Overall, the work concluded that the negative effects of increasing the minimum wage are small and significantly smaller than believed 30 years ago, the Nobel committee said.
Card also found that the incomes of those who are native-born in a country can benefit from new immigrants, while immigrants who arrived earlier are the ones at risk of being negatively affected.
Angrist and Imbens won half of the award for working out the methodological issues that allow economists to draw solid conclusions about cause and effect even where they cannot carry out studies according to strict scientific methods.
Speaking by phone from his home in Massachusetts, Imbens told reporters that he had been asleep when the call came.
I was just absolutely stunned then to get a telephone call" he said. “And then I was just absolutely thrilled to hear the news, a particular kind of hearing that I got to share this with Josh Angrist and David Card were both very good friends of mine.”
Unlike the other Nobel prizes, the economics award wasn’t established in the will of Alfred Nobel but by the Swedish central bank in his memory in 1968, with the first winner selected a year later. It is the last prize announced each year.
Last week, the 2021 Nobel Peace Prize was awarded to journalists Maria Ressa of the Philippines and Dmitry Muratov of Russia for their fight for freedom of expression in countries where reporters have faced persistent attacks, harassment and even murder.
Ressa was the only woman honoured this year in any category.
The Nobel Prize for literature was awarded to UK-based Tanzanian writer Abdulrazak Gurnah, who was recognized for his uncompromising and compassionate penetration of the effects of colonialism and the fate of the refugee.
The prize for physiology or medicine went to Americans David Julius and Ardem Patapoutian for their discoveries into how the human body perceives temperature and touch.
Three scientists won the physics prize for work that found order in seeming disorder, helping to explain and predict complex forces of nature, including expanding our understanding of climate change.
Benjamin List and David WC MacMillan won the chemistry prize for finding an easier and environmentally cleaner way to build molecules that can be used to make compounds, including medicines and pesticides.
