 Along with her husband Vincent Ostrom, Elinor Ostrom developed the idea of polycentric governance, according to which we are citizens of multiple, overlapping, and nested communities, from the smallest neighborhoods to the globe. Collective action problems are best addressed polycentrically, not reserved for national governments or parceled out neatly among levels of government. As president of the American Political Science Association and in other prominent roles, Ostrom advocated civic education that would teach people to address collective action problems in multiple settings and scales.
