Three United States-based economists shared the Nobel Prize in economics for a study on raising the minimum wage and a study on immigration in the workforce.

David Card, an immigrant from Canada working at the University of California, Berkeley, received half the award for his studies on the effects of raising the minimum wage. The foundation said Joshua Angrist from the Massachusetts Institute of Technology and Dutch American Guido Imbens from Stanford University received credit “for their methodological contributions to the analysis of causal relationships.”
