Efficient Mechanisms for Public Goods with Use Exclusions
研究在偏好为私人信息时，如何有效提供可排他的公共物品，发现最优机制可近似为固定数量加固定用户费，且当名字不反映偏好时支持平均成本定价。
Constrained efficient provision of an excludable public good is studied in a model where preferences are private information. The provision level is asymptotically deterministic, making it possible to approximate the optimal mechanism with a mechanism that provides a fixed quantity of the good and charges fixed user fees for access. In general, the fixed fees involve third degree price discrimination, but, if names are uninformative about preferences, the analysis provides a justification for average cost pricing.
