Subpart (a):

To determine

Multiplier, MPC and change in GDP.

Subpart (a):

Expert Solution

Explanation of Solution

Multiplier can be calculated as follows:

Multiplier=11−MPS=11−0.4=2.5

Multiplier is 2.5. If the MPS is 0.4, the multiplier will be 2.5.

If the MPS is 0.6 then the multiplier can be calculated as follows:

Multiplier=11−MPS =11−0.6 =1.6667

If MPS is 0.6, the multiplier will be 1.667. If the MPS is 1 then the multiplier will be infinity or undefined.

Economics Concept Introduction

Concept Introduction:

Multiplier: Multiplier refers to the ratio of change in the real GDP to the change in initial consumption at constant price rate. Multiplier is positively related to the marginal propensity to consumer and negatively related with the marginal propensity to save.

Marginal propensity to consume (MPC): Marginal propensity to consume refers to the sensitivity of change in the consumption level due to the changes occurred in the income level.

Marginal propensity to save (MPS): Marginal propensity to save refers to the sensitivity of change in the saving level due to the changes occurred in the income level.

GDP (Gross Domestic Production): GDP refers to the market value of all final goods and services produced in an economy during an accounting year, at particular price.

Subpart (b):

To determine

Multiplier, MPC and change in GDP.

Subpart (b):

Expert Solution

Explanation of Solution

If MPC is 1, then the multiplier will be infinity or undefined. If MPC is 0.90, then the multiplier can be calculated as follows:

Multiplier=11−MPC =11−0.90 =10

Hence, when MPC is 0.90, then the multiplier will be 10.

If MPC is 0.67, then multiplier can be calculated as follows:

Multiplier=11−MPC =11−0.67 =3.0303

Hence, when MPC is 0.67, then the multiplier will be 3.

If the MPC is 0.50, then the multiplier can be calculated as follows:

Multiplier=11−MPC =11−0.50 =2

Hence, when MPC is 0.50 the multiplier will be 2.

If MPC is 0, then the multiplier can be calculated as follows:

Multiplier=11−MPC =11−0 =1

Hence when MPC is 1, then the multiplier will be 1.

Just Part D please, this is for environmental economics

3. Consider a single firm that manufactures chemicals and generates pollution through its emissions E. Researchers have estimated the MDF and MAC curves for the emissions to be the following: MDF = 4E and MAC = 125 – E Policymakers have decided to implement an emissions tax to control pollution. They are aware that a constant per-unit tax of $100 is an efficient policy. Yet they are also aware that this policy is not politically feasible because of the large tax burden it places on the firm. As a result, policymakers propose a two- part tax: a per unit tax of $75 for the first 15 units of emissions an increase in the per unit tax to $100 for all further units of emissions With an emissions tax, what is the general condition that determines how much pollution the regulated party will emit? What is the efficient level of emissions given the above MDF and MAC curves? What are the firm's total tax payments under the constant $100 per-unit tax? What is the firm's total cost of compliance…

2. Answer the following questions as they relate to a fishery: Why is the maximum sustainable yield not necessarily the optimal sustainable yield? Does the same intuition apply to Nathaniel's decision of when to cut his trees? What condition will hold at the equilibrium level of fishing in an open-access fishery? Use a graph to explain your answer, and show the level of fishing effort. Would this same condition hold if there was only one boat in the fishery? If not, what condition will hold, and why is it different? Use the same graph to show the single boat's level of effort. Suppose you are given authority to solve the open-access problem in the fishery. What is the key problem that you must address with your policy?

If MPC is 0.67, then multiplier can be calculated as follows:

Multiplier=11−MPC =11−0.67 =3.0303

Hence, when MPC is 0.67, then the multiplier will be 3.

If the MPC is 0.50, then the multiplier can be calculated as follows:

Multiplier=11−MPC =11−0.50 =2

Hence, when MPC is 0.50 the multiplier will be 2.

If MPC is 0, then the multiplier can be calculated as follows:

Multiplier=11−MPC =11−0 =1

Hence when MPC is 1, then the multiplier will be 1.

Economics Concept Introduction

Concept Introduction:

Multiplier: Multiplier refers to the ratio of change in the real GDP to the change in initial consumption at constant price rate. Multiplier is positively related to the marginal propensity to consumer and negatively related with the marginal propensity to save.

Marginal propensity to consume (MPC): Marginal propensity to consume refers to the sensitivity of change in the consumption level due to the changes occurred in the income level.

Marginal propensity to save (MPS): Marginal propensity to save refers to the sensitivity of change in the saving level due to the changes occurred in the income level.

GDP (Gross Domestic Production): GDP refers to the market value of all final goods and services produced in an economy during an accounting year, at particular price.

Answer 15

Subpart (b):

Expert Solution

Explanation of Solution

If MPC is 1, then the multiplier will be infinity or undefined. If MPC is 0.90, then the multiplier can be calculated as follows:

Multiplier=11−MPC =11−0.90 =10

Hence, when MPC is 0.90, then the multiplier will be 10.

If MPC is 0.67, then multiplier can be calculated as follows:

Multiplier=11−MPC =11−0.67 =3.0303

Hence, when MPC is 0.67, then the multiplier will be 3.

If the MPC is 0.50, then the multiplier can be calculated as follows:

Multiplier=11−MPC =11−0.50 =2

Hence, when MPC is 0.50 the multiplier will be 2.

If MPC is 0, then the multiplier can be calculated as follows:

Multiplier=11−MPC =11−0 =1

Hence when MPC is 1, then the multiplier will be 1.

To determine

Multiplier, MPC and change in GDP.

Subpart (c):

Expert Solution

Explanation of Solution

Multiplier can be calculated as follows:

Multiplier=11−MPC =11−0.8 =5

Change in the level of GDP can be calculated as follows:

Change in GDP=Multiplier×Investment =5×8 billion =40 billion

Hence, the change in GDP is by $40 billion.

Subpart (d):

To determine

Multiplier, MPC and change in GDP.

Subpart (d):

Expert Solution

Explanation of Solution

In case, if 0.67 is MPC, the change in GDP will be equal to $24 billion. In this case, the multiplier will be 3.

Multiplier can be calculated as follows:

Multiplier=11−MPC =11−0.67 =3.03

Change in the level of GDP can be calculated as follows:

Change in GDP=Multiplier×Investment =3.03×8 billion =24.24 billion

Hence, the change in GDP is by $24.24 billion.
