Introduction to the Oliver E. Williamson memorial issue.

Oliver E. Williamson, who died on May 21, 2020 at the age of 87, was one of the most influential social scientists of modern times. In 2009, he was co-recipient of the Nobel Prize in Economics. As of mid-October 2021, he had been cited an astonishing 317,838 times according to Google Scholar. His measured influence outdistances that of even his fellow Nobel Laureates Elinor Ostrom (230,667), Douglass C. North (187,577) and Ronald H. Coase (123,686). This special issue of the Journal of Institutional Economics brings together a distinguished roster of scholars to remember Williamson, to elucidate some of his key ideas and influences, and to extend the reach of his ideas to new arenas.
