Leadership on the Commons: Wealth Distribution, Co-provision and Service Delivery
通过纵向研究，发现集体行动结果不仅受异质性本身影响，更取决于其与生物物理和制度环境的互动过程，对贫困与非贫困资源用户的政策制定有启示。
There has been a long running debate among public choice theorists on the effects of heterogeneity on collective action. Our longitudinal study leads us to conclude that collective action outcomes are shaped not simply by the attributes of heterogeneity themselves but by the processes by which those attributes interact over-time with the bio-physical and institutional environment. From a methodological point of view how one integrates conceptualization of forms of heterogeneity with recognition of their axis of influence; themselves dependent upon attributes of field-level situations is crucial for analysis of collective action. These findings have public policy implications for targeting of poor and non-poor resource users and management of environmental feedback loops.
