Is the Tragedy of the Commons Likely? Factors Preventing the Dissipation of Fuelwood Rents in Zimbabwe
研究津巴布韦农村薪柴资源虽名义上开放获取，但社会规范与用户异质性阻止了经济租金消散，随机效用模型显示这些因素显著影响选址，福利测度表明存在正向场地租金，公地悲剧不太可能发生。
<i>Although village “rules” classify fuelwood resources in rural Zimbabwe as being open-access, theory suggests that social norms and/or heterogeneity among users prevents rents from being dissipated. Results from a Random Utility Model suggest that social norms and heterogeneous travel costs significantly influence site choice. Welfare measures suggest that there are positive site rents, and that these rents vary because social norms and/or heterogeneity are preventing rent dissipation at some sites more than others. Given the prevalence of social norms and heterogeneity in costs, the “tragedy-of-the commons” is unlikely.</i>
