Document Summary

If the mps is 0. 2, a billion decrease in planned investment will cause aggregate output to decrease by: 200 billion, assuming there is no government or foreign sector, the formula for the multiplier is. If c = 1,000 +. 75y and i = 500, then planned savings equals planned investment at aggregate output level of. If c = 100 +. 9y and i = 50, then the equilibrium level of income is 750. 4: at the equilibrium level of output, consumption equals 3,100, at the equilibrium level of output, saving = 400, after government is added, the formula for the aggregate consumption function is, c = a + b (y-t) Chapter 10 quiz: the accounting books of the fed, assets: 3: president of the ny fed always gets a vote. 3: other checkable deposits. travelers checks, decrease in the money supply: fed sells government securities.

Assume the following values of an economy.

Planned Investment (Ip) = $20

Autonomous Consumption (C ) = $30

Marginal Propensity to consume (MPC) = .9

What is the equilibrium income?

Y* = aggregate demand at the equilibrium level. (Consumption + investment)

Consumption function = autonomous consumption + mpc * Y.

C=30 + .9Y

AD = 30 + .9Y + 20 = 50 + .9Y

Y= 50 + .9Y.1Y = 50

Y = $500 is the equilibrium level of income.

What is the value of saving at equilibrium?

Savings = income - consumption at the equilibrium level of Y=500,

Consumption = 30 +.9 * 500 = $480

Savings = 500 - 480= 20

c. Does the saving and Investment Identity hold true at equilibrium income OR GDP?

Since planned investment = $20 which is equal to savings calculated, the saving investment identity holds true at equilibrium income.

2. In addition to the values given in question (1) above, assume the government increases its spending by $30 without raising taxes. The government can do this by borrowing from the private sector.

a. Based on this information calculate the new level of equilibrium income.

If Government expenditures = $30, Y = C + I + G

Y = 1/1-.09 * (30+20+30) Y = 800

b. Calculate the total value of consumption at equilibrium.

C = 30 + .9(800) = 750

c. Calculate the total value of saving at equilibrium.

Savings = I - C = 800 - 750 = 50

3. In addition to questions in (1 & 2) above, assume the government decides to raise autonomous taxes by $30 to balance its budget.

What is the new value of equilibrium income?

Y = 1/1-.9 (30-.9(30) +20+30) = 530

What is the value of the autonomous tax multiplier?

-.09/.01 = -9

c. What is the value of autonomous spending multiplier?

1/.1 = 10

On the planet Omicron Persei 8, government spending is $1000, net taxes are $1200, and planned investment is $1400. Consumers spend according to the equation C = 100 + 0.8Yd, where Yd represents disposable income. Given this information, fill out the table below to determine which of the output levels represents a macroeconomic equilibrium, then answer the questions that follow. Output (Income) Y Net Taxes T Disposable Income Yd Consumption C Planned Investment I Government Purchases G Planned Aggregate Expenditure AE Unplanned Inventory Change 6200 1200 5000 3850 1400 1000 6250 -50 6700 1200 5500 4225 1400 1000 6625 75 7200 1200 6000 4600 1400 1000 7000 200 7700 1200 6500 4975 1400 1000 7375 325 8200 1200 7000 5350 1400 1000 7750 450

An a. Which level of output is a macroeconomic equilibrium? There is no level of equilibrium based on inventory levels.

b. Is the government budget balanced, in deficit, or surplus, and by how much? Since the government is spending less than it is collecting in taxes, we are showing a surplus.

c. Find the marginal propensity to consume, and the marginal propensity to save. d. Find the government spending multiplier. If the government wanted to increase the equilibrium level of income by $1,000, how much would it have to increase government purchases? e. Find the tax multiplier. If net taxes were lowered by $100, what effect would it have on the equilibrium level of income? Give a specific numerical answer.
