Then along came Elinor "Lin" Ostrom and her 1990 work "Governing the Commons." In it, Ostrom presented game theory approach to commonly owned resources, explaining how people as self-interested rational actors could avoid the logical trap of over exploitation. And then she did Hardin one better: she detailed the workings of actual extant commons which, according to Hardin and every neoliberal since, should not exist.
Ostrom illustrated what anthropologists and people in stateless societies have known for generations: people are perfectly capable of working out rules to sustainably manage shared resources. In her book, Ostrom detailed one common pasture in Switzerland that has been in continuous use since the 1500s. She also described shared fishing rights in Turkey, shared agricultural and forest land in Japan, and shared irrigation systems in Spain. There is no tragedy.
