Question 1

Determining a target level of environmental quality is an example of _______.

Accepted Answer

Determining a target level of environmental quality involves making a value judgment about what level of environmental quality is desirable. This is an example of normative policy analysis, which involves analyzing what ought to be done from a moral or ethical perspective, rather than simply describing what has happened or what the consequences of different policies might be (positive policy analysis). Benefit-cost analysis involves comparing the costs and benefits of different policy options, which may be one part of determining a target level of environmental quality, but it is not the only consideration. Positive economics involves studying the way the economy behaves, rather than making normative judgments about what it should look like.

Question 2

In the following figure,the total damage cost of 25 units of emissions is equal to _______.

Accepted Answer

Looking at the graph, we can see that the cost of damage for 1 unit of emissions is $5. Therefore, the total cost for 25 units of emissions would be:
25 x $5 = $125. So, the answer is B.

Question 3

The height of the marginal damage curve at a particular level of emissions shows how much total damages change if there is a small change in the quantity of emissions.

Accepted Answer

The marginal damage curve measures the change in total damages when there is a small change in the quantity of emissions. The height of the curve at a particular level of emissions represents the rate of change of total damages with respect to changes in emissions at that level, and therefore shows how much total damages change with a small change in emissions.

Question 4

For a firm with more than one source of emissions,the ________ states that the total costs of abating a given abatement target will be minimized when the marginal costs of abatement are ________ across sources.

Accepted Answer

The equimarginal principle holds that total costs of abating a given abatement target will be minimized when the marginal costs of abatement are equalized across sources. This means that the cost of abating a unit of emissions from one source should be equal to the cost of abating a unit of emissions from another source. Therefore, option A is the correct answer.

Question 5

In the following figure,the marginal abatement cost of abating the 20^th unit of emissions is _______.

Accepted Answer

The answer of In the following figure,the marginal abatement cost...

Question 6

Under what circumstances would a firm with more than one source of production minimize its total costs of production by setting production levels equal at each source?

Accepted Answer

When each source has identical marginal cost of production structures, setting production levels equal at each source results in the firm minimizing its total production costs. This is because producing more at one source than another would increase the marginal cost at the former and decrease the marginal cost at the latter, leading to an overall increase in total production costs. By setting production levels equal at each source, the firm can balance its production across its sources and avoid incurring unnecessary production costs.

Question 7

Describing and explaining economic events that have taken place in the real world is known as positive economics.

Accepted Answer

Positive economics is the branch of economics that deals with objectively describing and explaining economic phenomena that have taken place in the real world without making any value judgments or opinions.

Question 8

Question 9

The study of what ought to be such as determining the socially efficient level of emissions is known as normative economics.

Accepted Answer

Normative economics is concerned with what ought to be, while positive economics is concerned with what is. Therefore, determining the socially efficient level of emissions falls under the realm of normative economics.

Question 10

Accepted Answer

The answer of In the following figure,the uncontrolled level of...

Question 11

For certain pollutants with a(n)_______,emissions or ambient quality up to a certain level cause _________ damages.

Accepted Answer

Pollutants with a threshold have a level below which emissions or ambient quality do not cause damages, implying that up to a certain level, there are no damages.

Question 12

For a marginal damage cost function equal to: MD = 0.8E,the marginal damage cost of the 50^th unit of emissions is _______.

Accepted Answer

To calculate the marginal damage cost of the 50^th unit of emissions, we simply need to substitute E = 50^th into the given marginal damage cost function: MD = 0.8E MD = 0.8(50^th) MD = 40^th Therefore, the marginal damage cost of the 50^th unit of emissions is $40, which is option B.

Question 13

Suppose there are three polluting sources with MAC₁ = 100 - 4E,MAC₂ = 80 - 2E and MAC₃ = 60 - 0.5E.When MAC equals $10,the aggregate level of abatement for these sources would be _______.

Accepted Answer

To find the aggregate level of abatement we need to add up the individual level of abatements for each source at MAC=10. 
For MAC=10, 
source 1: 100-4E = 100-4*10 = 60 
source 2: 80-2E= 80-2*10 = 60 
source 3: 60-0.5E=60-0.5*10=55 
So, the level of abatement for each source would be: 
source 1: 100-60 = 40 
source 2: 80-60 = 20 
source 3: 60-55 = 5 
Thus, the aggregate level would be 40+20+5=65 units. 
Therefore, the correct choice is B) 157.5 units. 
(Note: The answer choices have incorrect values of aggregate level. The correct calculation of the aggregate level for MAC=10 gives 65 units, not any of the answer choices given.)

Question 14

In the following figure,the marginal damage cost of the 25^th unit of emissions is equal to _______.

Accepted Answer

From the graph, we see that the marginal damage cost curve intersects the x-axis at 25 units of emissions. This means that the 25th unit of emissions imposes no marginal damage cost. Therefore, the marginal damage cost of the 25th unit of emissions is equal to the area under the curve from 25 to 26 units of emissions, which is a rectangle with base 1 and height 10, equaling $10.

Question 15

A(n)________ shows how damages are related to the concentration of a waste product contained in the ambient environment.

Accepted Answer

An ambient damage function shows the relationship between the concentration of a waste product in the environment and the resulting damages, effectively linking environmental pollution levels to their impacts.

Question 16

Under what circumstances would a firm with more than one source of emissions minimize its total costs of abatement by setting abatement levels equal at each source?

Accepted Answer

If each source has identical marginal abatement cost structures, then setting abatement levels equal at each source will result in the firm minimizing its total abatement costs. This is because the firm can achieve the same reduction in emissions at each source at the same cost, so spreading the abatement evenly across sources minimizes the total cost of abatement.

Question 17

For a single,non-accumulative pollutant,when no threshold exists the marginal damage function begins at the origin.
When no threshold exists,the very first unit of emissions has an impact on the environment.

Accepted Answer

When no threshold exists for a single, non-accumulative pollutant, the marginal damage function begins at the origin, which means that even the first unit of emissions has an impact on the environment. Therefore, the statement is true.

Question 18

A marginal damage function that becomes vertical at high levels of emissions represents _______.

Accepted Answer

The answer of A marginal damage function that becomes vertical...

Question 19

For a firm with more than one source of output with differing cost structures,its ________ will be minimized when its ________ are equalized across sources.

Accepted Answer

For a firm with multiple sources of output, minimizing total production costs is achieved when the marginal production costs across all sources are equal. This is because, at the point where the marginal costs of producing an additional unit of output are the same for all sources, reallocating production would not reduce costs further.

Question 20

Suppose there are three polluting sources with MAC₁ = 75 - 0.25E,MAC₂ = 120 - 4E and MAC₃ = 50 - 0.5E.When MAC equals $20,the aggregate level of abatement for these sources would be _______.

Accepted Answer

To determine the aggregate level of abatement, we need to find the value of E (emission level) for each polluting source when MAC= $20. For MAC₁ = 75 - 0.25E, substituting MAC=$20 gives: $20 = 75 - 0.25E 0.25E = 55 E = 220 For MAC₂ = 120 - 4E, substituting MAC=$20 gives: $20 = 120 - 4E 4E = 100 E = 25 For MAC₃ = 50 - 0.5E, substituting MAC=$20 gives: $20 = 50 - 0.5E 0.5E = 30 E = 60 Therefore, the aggregate level of abatement = (220-20) + (120-25) + (50-60) = 200+95-10 = 305 units. So, the answer is C.
