Using the table below to answer the following questions. Assume all values represent trillions of dollars.
Construct a graph of the Aggregate planned expenditure
What is the equilibrium expenditure?
Explain what happens at a real GDP of $4 trillion dollars. (Note the aggregate
expenditures and the effects on inventories)
What are your total autonomous expenditures?
What is the marginal propensity to consume?
Ignoring imports and income taxes, what is the multiplier?
If investment increases by $1.5 trillion, what is the change in real GDP?
1) Consider economy T described by the parameters below:
C=1500+0.6Y
I = 1200
G=2500
X =500
M = 400
T = 1000
a. Identify the marginal propensity to consume (MPC) in T.
b. What will be the value of the equilibrium GDP in economy T?
Calculate the value of the multiplier for economy T.
Suppose that country Y is identical to country Z, with the exception that country Y's population has a
lower marginal propensity to consume than country Z. Initially, both countries have the same level of real
GDP. The diagram shows the expenditure curve for country Y.
Using the line drawing tool, draw the expenditure curve of country Z in Figure 1. Label your curve 'Ez'.
Carefully follow the instructions above and only draw the required object.
