Question 4 [30 points] Externality and Tax This is an extension of the previous problem. Solving it before attempting this one is not required but might help your intuitions. In a market for electricity where energy sources come from two distinct producers—fossil fuel and renewable energy—the dynamics of pricing, production, and externalities are critical. Now suppose this market also features renewables, which operate under different cost structures and are influenced by varying policy incentives. The two producers of electricity have the following relationships between price (in cents) and quantity (in kilowatt-hours) supplied: • Fossil Fuels: $Q_{FF} = 2P - 2$ • Renewables: $Q_R = P - 4$ The total market demand for electricity is given by $P = 30 - Q$, where $P$ is the price in cents and $Q$ is the quantity in kilowatt-hours. Suppose Fossil fuel producers create external damages of 2 cents per kilowatt-hour of electricity they produced. a) (10 points) Determine the equilibrium price and total quantity of electricity in the market. Find the quantity produced by both fossil fuel and renewable energy producers. Illustrate this equilibrium graphically. In the context of a mixed energy market, analyze what the equilibrium allocation of fossil fuel and renewable energy implies about the cost competitiveness and market share of each producer type. b) (10 points) Suppose the government imposes a tax of 2 cents per kilowatt-hour only on fossil fuel producers. What price will consumers now pay for electricity, and what will be the new quantity of electricity consumed? How does the tax affect consumer behavior—does it incentivize a shift toward renewables? c) (10 points) Analyze the impact of the tax on the production of fossil fuel and renewable energy, specifically calculating the change in quantity produced by each. What implications does this shift have for the market share of each energy source? Bonus 5 points Challenging. This question is a bonus question and is not a required question. Suppose the government wants to make the 2-cent tax on fossil fuel producers revenue-neutral by transferring the tax revenue to renewable energy producers as a per-kilowatt-hour subsidy. Determine the new equilibrium price and the quantities produced by fossil fuel and renewable energy producers under this revenue-neutral system.
