Explain the basic idea of the expenditure multiplier and the role consumers' play.
The following are exogenous (not directly affected by income):
G = 9
I = 14
X = M = 0
The consumption function is:
C = k + cY, where k = 8, c = 0.6
What is the equilibrium level of GDP? State to ONE decimal place
What is the multiplier for this economy?
The following are exogenous (not directly affected by income):
G = 11
I = 4
X = M = 0
The consumption function is:
C = k + cY, where k = 3, c = 0.8

Same information as in the previous question:
The following are exogenous (not directly affected by income):
G = 11
I = 4
X = M = 0
The consumption function is:
C = k + cY, where k = 3, c = 0.8
Imagine the maximum potential output or real GDP of this economy is 100. Assume that is the same as saying we reach the edge of the PPF at 100.
Now assume we want to get that economy from the current level of GDP to its maximum potential of 100.
We can do this in two ways - either increase government spending (G) or reduce taxes, (we…
Q1:You are given the following income-expenditures model for an economy :
Consumption C = 300 + .64Yd
Tax (T) = $60
Government expenditure G = $100
Investment (I) = $120
From above data calculate the follows:
1. Equilibrium level of income
2. At the equilibrium level of income, what is the amount of consumption?

- In an economy, autonomous consumption expenditure is $50 billion, investment is $200 billion, and government expenditure is $250 billion. The marginal propensity to consume is 0.7 and net taxes are $250 billion. Exports are $500 billion and imports are $450 billion. Assume that net taxes and imports are autonomous and the price level is fixed. What is the consumption function? What is the equation of the AE curve? Calculate equilibrium expenditure. Calculate the multiplier. If investment decreases to $150 billion, what is the change in equilibrium expenditure?

Which one? A/ It is the idea that decreasing national income affects the equilibrium level of GDP by the same amount of that decrease in income. B/ It is the concept that increasing national income affects the equilibrium level of GDP on par with the amount of increased income. C/ The expenditure multiplier is the idea that a given change in spending leads to an equal change in the equilibrium level of GDP. D/ It is the concept that an increase in spending causes a more than proportionate change in GDP.arrow_forwardSuppose the United States economy is represented by the following equations: Z = C + I + G C = 500 + .5YD T = 600 I = 300 YD = Y - T G = 2000 Given the above variables, calculate the equilibrium level of output.
