There is a strong relationship between the study of the commons, collective action, and public policy analysis. Public policy is often justified as a means for governments to incentivize individuals to act in the public interest, which may involve creating new types of commons, fostering collective action, and/or regulating these activities through state mechanisms. Many analyses of commons governance explore the interaction between state and non-state actors, considering both informal norms and formal rules that enable diverse forms of cooperation to address complex social-ecological dilemmas, often referred to as state-reinforced self-governance. This subtheme encourages participants to submit presentation abstracts that explore a range of topics related to commons governance, the State, and public policy. Potential topics include institutional design, polycentric governance, co-management (e.g., co-provision and co-production), and interventions that facilitate diverse outcomes at the intersection of public policy and the commons. We are particularly interested in submissions that advance policy theory, methodology, or practice. Program Committee sub-theme members: Daniel DeCaro, Tanya Heikkila, Ilkhom Soliev
