1. Negative externalities Consider two firms, each owning an oil refinery that both produce fuel. Fuel...
Consider two firms (i.e., firms 1 & 2) with heterogeneous marginal abatement cost functions: MAC1=12 - 2E1 MAC2 =10 - E2 Assume the marginal external damages from emissions are: M E D = 1/2 E A . where EA is the sum of the two firms’ emissions. What quantity of emissions do firms produce in the absence of government intervention? What are the total external damages? What are the total abatement costs? Derive the aggregate marginal abatement cost function (Hint:...
For questions (2) and (3) suppose the government imposes an emission standard on the firms requiring Firm 1 to reduce emissions by 30 tons and Firm 2 to reduce emissions by 20 tons. Question 2 10 pts Does the emission standard bring about a cost-effective allocation of pollution control responsibility? Yes NO Question 3 10 pts Calculate the total cost of pollution control for Firm 1 and for Firm 2. TCC1 - $ TCC2 = $ rvices Consider an industry...
Consider two firms (i.e., firms 1 & 2) with heterogeneous marginal abatement cost functions: MAC1 =12−2E1MAC2 =10−E2. Assume the marginal external damages from emissions are: M E D = 12 E A . where EA is the sum of the two firms’ emissions. What quantity of emissions do firms produce in the absence of government intervention? What are the total external damages? What are the total abatement costs? Derive the aggregate marginal abatement cost function (Hint: This will be a...
1. Suppose an economy consisting of two factories and two neighbours in which these factories are all polluters with e is the quantity of emissions generated by each factory. Firm 1 has an abatement cost function of AC (e) = 0.5e 2 -5e while the abatement cost for Firm 2 is AC (e)= e 2 – 8e. Marginal damage for each consumer is defined by MD(e) = e, where e here is the total amount of emissions the consumer is...
7. Correcting for negative externalities - Taxes versus tradable permits Power stations emit sulfur dioxide as a waste product. This generates a cost to society that is not paid for by the firm; therefore, pollution is a negative externality of power production. Suppose the U.S. government wants to correct this market failure by getting firms to internalize the cost of pollution. To do this, the government can charge firms for pollution rights (the right to emit a given quantity of...
Correcting for negative externalities - Taxes versus
tradable permits
Power stations emit sulfur dioxide as a waste product. This
generates a cost to society that is not paid for by the firm;
therefore, pollution is a negative externality of power production.
Suppose the U.S. government wants to correct this market failure by
getting firms to internalize the cost of pollution. To do this, the
government can charge firms for pollution rights (the right to emit
a given quantity of sulfur...
2. There are only two polluting sources in the region, each of which generates 10 units of pollution for a total of 20 units released into the environment, The government determines that emissions must be reduced by 12 units across the region to achieve the "socially desirable level of pollution". Each firm faces different abatement cost conditions modelled as follows: for Pol- luter 1, marginal abatement cost is MAC1-2.6Q1, while the total abate- ment cost is TAC1 1.3(Q1)2. For Polluter...
There are two firms producing cement. Each produces 20 units of pollution, and each has the ability to reduce pollution (abate) their emissions by operating some machine. The marginal damage of each unit of pollution to society is $3 (i.e., the marginal benefit of each unit of abatement is $3). The total cost of firm 1 is where denotes the amount of abatement of firm 1. The total cost of firm 2 is where denotes the amount of abatement of...
Exercise 11.3 Consider the following duopoly model. There are two firms sup- plying a market where demand is given by p(Q)- a-bQ. Firm i produces qi units of output and so the total level of production is q1q2. Both firms face the same constant marginal cost, so the cost of producing qi for firm i įs cqỉ. Thus the profit functions of firms 1 and 2 respectively, are given by: (a) Suppose that each firm takes the output of the...

5. Correcting for negative externalities - Regulation versus tradable permits Suppose the government wants to reduce the total pollution emitted by three local firms. Currently, each firm is creating 4 units of pollution in the area, for a total of 12 pollution units. If the government wants to reduce total pollution in the area to 6 units, it can choose between the following two methods: Available Methods to Reduce Pollution 1. The government...
