不确定生产率下共有池资源的收入分享
Income sharing for common pool resources with uncertain productivity
摘要
We address the interconnected issues of externalities in the use of a natural common‐pool resource system and adverse effects of environmental uncertainty on risk‐averse resource users. We set up a simple analytical model and derive conditions such that insurance by means of an income sharing mechanism mitigates externalities and hence achieves a socially optimal outcome. For this to materialize, we show that the sharing rule must be sufficiently sensitive to individual contributions and specifically show that a simple proportional sharing rule can provide incentives for both efficient contributions to the income pool and efficient use of the resource system.
中文摘要
本文探讨了自然共有池资源系统使用中的外部性问题，以及环境不确定性对风险规避型资源使用者造成的不利影响，并分析了两者之间的相互关联。我们构建了一个简单的分析模型，推导出相应条件，使得通过收入分享机制实现的保险能够缓解外部性，从而实现社会最优结果。为使之成为现实，我们表明分享规则必须对个体贡献足够敏感，并具体证明简单的比例分享规则能够为有效贡献收入池和有效使用资源系统提供激励。
