Economists Card, Angrist and Imbens win 2021 Nobel prize

Economists David Card, Joshua Angrist and Guido Imbens won the 2021 Nobel economics prize, the Royal Swedish Academy of Sciences announced on Monday. They see a winners' share of 10 million Swedish crowns ($1.14 million).

Canada-born Card took half the prize for his empirical contributions to labour economics, the academy said, while Angrist and Imbens shared the other half for their methodological contributions to the analysis of causal relationships.

"2021 economic sciences laureates Joshua Angrist and Guido Imbens showed what conclusions about cause and effect can be drawn from natural experiments. The framework developed by them has been widely adopted by researchers who work with observational data," said the academy.


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.

The prestigious prizes for achievements in science, literature and peace were created and funded in the will of Swedish dynamite inventor and wealthy businessman Alfred Nobel.

They have been awarded since 1901, though the economics prize - created through a donation from Sweden's central bank on its 300th anniversary - is a later addition that was first handed out in 1969.
