One way to fund a public good is to charge for admission. But, we argued in class that this doesn't necessarily lead to efficiency. One problem is that the price that is needed to fund the good might be higher than the willingness to pay of some uses. Excluding those users is inefficient for a good without congestion. Furthermore, if some people aren't willing to pay the entrance fee and are excluded, then the efficient quantitycontingent on the users who would access itwould be different. This represents another aspect of potential inefficiency. Let's assume that our public good is excludable-we can restrict access to it and there- fore we could charge users for access. Continue to assume that N=5. 5. If N=5 and the efficient level of the public good is provided, what is the minimum price that would provide enough revenue from selling access if all 10 users pay
