"This paper studies the optimal provision mechanism for multiple excludable public goods when agents' valuations are private information. For a parametric class of problems with binary valuations, we demonstrate that the optimal mechanism involves bundling if a regularity condition, akin to a...

This paper provides an economic explanation for the increasing reliance of the state on revenue from user charges on excludable public goods. We develop a model with many identical countries. The government of each country levies a capital tax on the domestic production sector and supplies an...
