A monopolist faces the inverse demand for its output: p = 30 - Q
The monopolist also has a constant marginal and average cost of $4/unit. The government is seeking ways to collect tax revenue from the monopolist and faces two proposals:
i. Impose a specific tax of t on the monopolist.
ii. Impose an ad valorem tax of a on the monopolist.
a) Suppose the government imposes a 20% ad valorem tax on the monopolist. What price and quantity does the monopolist choose and how much revenue does the government generate from the tax?
b) Rather than an ad valorem tax, what is the government's revenue from a specific tax of t imposed on the monopolist? Your answer should be in terms of ‘t'.
c) Show that a specific tax of $3.70/unit generates the same revenue as a 20% ad valorem tax (approximately).
