The 2025 Sveriges Riksbank Prize for Economic Sciences in Memory of Alfred Nobel has been awarded to three researchers who have shown how technological and scientific innovation, coupled to market competition, drive economic growth. One half of the prize goes to economic-historian Joel Mokyr of Northwestern University in Evanston, Illinois, and the other half is split between the economic theorists Philippe Aghion of the Collège de France and the London School of Economics and Peter Howitt of Brown University in Providence, Rhode Island. "I can't find the words to express what I feel," Aghion said. He says he will use the money for research in his laboratory at the Collège de France.
