Natural experiments in economics: a blog for the Lindau Nobel Foundation

Three professors who have spent their careers carrying out experiments in real life is the mark of the supremacy of the so-called “credibility revolution” in economics were awarded the Sveriges Riksbank Prize in Economic Sciences in November 2021.

David Card, a professor at the University of California, Berkeley, shared the prize with Massachusetts Institute of Technology professor Joshua Angrist and Stanford University professor Guido Imbens. Half of the prize was awarded to Card and the other half jointly to Angrist and Imbens.

For three decades they led the charge away from a focus on economic theory towards showing what conclusions about cause and effect can be drawn from natural experiments — real-life situations where chance events or policy decisions create similar conditions to those of a clinical trial.

Auctions and why they matter: a write up for Lindau Nobel Foundation

US academic Robert B. Wilson and his long-time collaborator and friend – and now neighbour – Paul R. Milgrom, won the Sveriges Riksbank Prize in Economic Sciences this year for their work on auction theory and how to improve them in action.

In the official announcement, the members of the Prize Committee said the pair’s insights had led to the design of new auction formats for goods and services that are difficult to sell in a traditional way, such as radio frequencies. Their discoveries have benefited sellers, buyers and taxpayers around the world, they said.
