In 2009, Ostrom became the first woman to receive the Nobel Memorial Prize in Economic Sciences. The Royal Swedish Academy of Sciences cited Ostrom "for her analysis of economic governance", saying her work had demonstrated how common property could be successfully managed by groups using it. Ostrom and Oliver E. Williamson shared the 10-million Swedish kronor (€990,000; $1.44 million) prize for their separate work in economic governance. As she had done with previous monetary prizes, Ostrom donated her award to the Workshop she helped to found.
