The government of Rosenia is considering the construction of a highway. This highway costs $8 million to build and once built it is non-rival in consumption and has no maintenance costs. The government can either finance its construction by charging a toll for the use of the highway or by doubling the existing tax rate in the market for books (and not charging a toll). The demand curve for highway use is given below.
