Ala Avoyan, Daniela Puzzello and James Walker received an NSF Conference grant to organize the Ninth Biennial Conference on Social Dilemmas at Indiana University. The ninth conference, which will be held in June 2025, builds upon a rich tradition of interdisciplinary collaboration initiated at Indiana University by the late Nobel Laureate Elinor Ostrom. This conference series, initiated in 2002, aims to deepen the understanding of collective action in social dilemma settings such as public goods provision, natural resource extraction, and climate change.
