Plants A and B emit 12 tons and 6 tons of carbon dioxide (CO2), respectively. MAC(marginal abatement costs) for a = 12 - Ea, MACb=12-2Eb MD(marginal damage) = 1/3*E (E indicates CO2 emission) Suppose the government decides to introduce a carbon tax on CO2 emissions. What is the tax amount (ie tax rate) per optimal ton of CO2 emissions? And what is the total revenue that would make the government sufficiently capable of introducing a carbon tax?
Consider a firm that emits pollution into the air. Suppose that the marginal damage costs associated with the emissions are given by MDC -15+ 4 c, where e is the quantity of the emissions. The firm's marginal costs of abatement are given by (a) (b) 390 (c) MAC 1200 - 20 c. Determine the quantity of emissions that the firm would discharge in the absence of government policy. Determine the socially efficient level of emissions. Calculate the total costs to society for both a and b and draw a diagram illustrating these costs.
The figure to the right shows the marginal cost of pollution abatement for two firms, A and B. The firms were initially abating 46 units of pollution each. Now they can trade pollution permits at a price of $22. As a result, firm A sells permits and firm B buys permits. Both firms are now better off and their total saving will be $ (Enter your answer rounded to the nearest whole number.)

Imagine a firm with a marginal abatement cost (MAC) function equal to: MAC = 32 - 4E. The government offers a $8 per-unit subsidy for abatement. In principle, the firm could ignore the subsidy and continue to emit as many emissions as it was in the absence of government intervention, but there is money to be made from cutting back its emissions. Compared to ignoring the subsidy, how much money could a cost-minimizing firm save or make by cutting back its emissions? (Hint: remember that firms trade off the benefits of the subsidy with the costs of abatement when deciding how much to abate) Answer:
No hand written solution Afirm has an industrial plant that emits pollutants into a town’s lake. The plant’s marginal abatement function is MAC= 200 – 0.5E and damages caused by its emissions are given by MD = 2E where emissions are in kg. per day. What is the socially efficient level of emissions from this plant? Illustrate this in a graph. As an incentive to reduce emissions to the socially efficient level, government offers to pay the firm for each kg. of emissions it abates per day from this plant. What subsidy per kg. should the government offer? If the plant abates to the socially efficient level of emissions, what total subsidy payment would the firm receive? Identify the area in your graph. How much better or worse off would the firm be compared to if it did no abating? Identify the area in your graph. What would be the net benefit to society if we pay the firm to reduce the plant’s emissions to the socially efficient level? Identify this area in your graph.
Draw a diagram of the marginal abatement cost curve described by: MAC = 100 - 2E. What is the uncontrolled level of emissions? What is the marginal abatement cost of the 40thunit of abatement? What is the total abatement cost of 40 units of abatement?
Suppose we are happy with the current level of total emissions across two firms but, the current marginal abatement cost for firm 1 is $200 and the current marginal abatement cost for firm 2 is $250. Have we divided total emissions in the best way? Why or why not?
MAC = 50 - 5E. The government offers a $30 per-unit subsidy for abatement. In principle, the firm could ignore the subsidy and continue to emit as many emissions as it was in the absence of government intervention, but there is money to be made from cutting back its emissions. Compared to ignoring the subsidy, how much money could a cost-minimizing firm save or make by cutting back its emissions?
Individuals go for flu injection not only protect themselves against flu but also help to prevent the disease from spreading in the community. (a) What type of externality occurs in the flu injection market? (b) Is the market outcome efficient? (c) What can the government do to rectify the externality issue?
Suppose the marginal damage cost is estimated to be MD = 0.8E and the marginal abatement cost is estimated to be MAC = 90 - E. Find the following: a) The socially efficient level of emission b) How much emission could be reduced from the uncontrolled level? c) the Total Social Costs d) Draw the graphs and show your calculations.
Which of the following are practical and effective policies to deal with carbon emissions caused by driving a car? A) A quota on individuals to limit their driving B) A tax on petrol C) Ownership of all affected assets D) Coasian bargaining (one side paying the other side to drive or not to drive)
The demand for energy-efficient TV is P = 100/Q, while the supply (marginal private cost) is MPC = Q. By reducing demand on the electricity network, energy- efficient TV generate an external marginal benefit, MEB = eQ. (a) What is the equilibrium quantity and price of energy-efficient TV in the private market? (b) If the socially efficient number of energy-efficient TV is Q = 20, what is the value of e? (c) If the government subsidized production of energy efficient TV by $S per unit, what level of the subsidy would induce the socially efficient level of production?
