Abstract: | This article analyzes local government fiscal sustainability as a common‐pool resource (CPR) problem. Comparing the experiences of Los Angeles County, San Bernardino City, and San Bernardino County, California, the analysis applies a framework developed from three decades of CPR research to show the importance of six micro‐situational variables—communications with the full set of participants, known reputations of participants, high marginal per capita return, entry or exit capabilities, longer time horizon, and agreed‐upon sanctioning capabilities—in shaping collective action dynamics and building the trust and reciprocity among stakeholders needed to achieve fiscal sustainability. The underlying contextual conditions for these micro‐situational variables vary based on specific socioeconomic and political settings, but the findings suggest that institutions and processes can be designed based on several well‐tested principles in CPR governance to encourage stakeholders to look beyond their immediate self‐interests and make decisions that account for the community's long‐term fiscal sustainability. |
