Question

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 2, marginal abatement cost is MAC2 0.52Q2, while the total abatement cost is TAC2 0.26(Q2)2. where Q1 is the amount of pollution controlled (abated) by Polluter 1, and Q2 is the amount of pollution controlled (abated) by Polluter2 (a) What is the cost effective abatement allocation across polluting sources? What is the total cost to achieve this goal? (b) Assume that the government implements the 12-units standard uni- formly, requiring each polluter to abate by 6 units. What is the total cost to achieve this goal? Is it more / less than the total cost from part a)? Comment on your findings.

    Problem 1 Assume that there are two factories, each emitting 20 units of pollutants into the environment, for a total of 40 units in their region. The government sets an aggregate abatement standard (AST) of 20 units. The polluters' cost functions are as follows, where the dollar values are in thousands:             Polluter 1:       TAC1 = 20 + 0.75(A1)2,                      Polluter 2:       TAC2 = 15 + 0.5(A2)2,                                           MAC1 = 1.5A1,                                                           MAC2 = A2.

The government sets an aggregate abatement standard (AST) of 30 units (total in the region). The polluters' cost functions are as follows, where the dollar values are in thousands: Polluter 1: TAC1 = 15 + 1.5(A1)2, MAC1 = 3A1.

    Suppose you have 2 polluting sources in a region. With the objective to mitigate pollution, the government sets emissions limits as 10 units per company (Ast). As a market oriented policy, the government imposes an emission charge of $10 per unit (MT 10) of tax after MT MAC condition is met. The following functions are calculated for both polluters Polluter 1: MAC1 4.0(A1) Polluter 2: MAC2 2.4(A2) Total tax per pollutert(Ast - Ao) Where Ao Actual units abated The graphs...

    Two thermic power plants have the following marginal and total cost of abatement of nitrogen oxide (NOx) emissions. When faced with no restrictions each of them emits maximum 100 ppm (parts per million) of NOx. Firm 1: MAC1=5 A1 TAC1=2.5 (A1)^2 Firm 2: MAC2 = 10 A2 TAC2= 5(A2)^2 (8 pts) The EPA finds the total NOx emissions of 200 ppm too much and seeks for improvement in air quality by specifying the reduction of 40% in total emissions from...

The local government wants to limit the total pollution to 20 tons since health studies find no serious deleterious impacts on human health at these levels of pollution. Firm A's marginal cost of abatement is 5X and Firm B's marginal cost of abatement is 2x where X and Xare the tons of toxin abated...

    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...

    The use of energy is one of the major causes of pollution and greenhouse gases that lead to climate change. It is desirable to reduce the emissions from energy use.  Suppose there are two firms whose marginal abatements costs are as follows: MAC1=q1 and MAC2=q2 where q1is the amount of emissions reduction by firm 1 and q2is the amount of emissions reduction by firm 2. In the context of this question, what is “marginal abatement cost”? Draw the two marginal abatement...
