An economist gives the following advice to a museum director: “You should introduce “peak pricing”. At times when the museum has few visitors, you should admit visitors for free. And at times when the museum has many visitors, you should charge a higher admission fee.”

When the museum is quiet, is it rival or non-rival in consumption? Is it excludable or non-excludable? What type of good – public or private - is the museum at those times? What would be the efficient price to charge visitors, and why? (I.e., should the price = $0, or should it be >$0?)

When the museum is busy, is it rival or non-rival in consumption? Is it excludable or non-excludable? What type of good is the museum at those times? What would be the efficient price to charge visitors, and why?
