Lecture 14 finishing up fiscal policy (chapter 10) & practice questions for midterm. Increasing the government spending by 450 in balanced budget = . Increasing the taxes spending by 450 in balanced budget = : both of these increases will result in an increase overall by 450. Multiplier rounds: suppose, marginal propensity to spend (mpspend) is 0. 5 (50% of money (income) spent) and suppose there is no taxes to pay by the consumer. I spent 100, followed by 50, 25, 12. 5, 6. 25, etc: the initial that i spent will generate a sequence of income in the economy. If we add all the generated incomes (100+50+25+12. 5+6. 25), it will be a multiple amount of the initial spending: the spending multiplier is 2 (1/(1-0/5)). Imports (money spent on foreign goods) will not benefit the domestic economy, but it benefits the economy of the country that the good is imported from.

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.

Unit 9: Keynesian Economics - Multipliers

Name _______________________________________________________

Answer the following problems. Show ALL work for every problem.

Keep in mind the equations you learned:

Change in G x SM = Change in AE

Also recall that if you know how much AE must change by AND you know the SM, you can solve for how much G must change by.

1. MPC = .9 AE must increase by $350 billion to reach the full employment level of RGDP. Solve for the change in Government spending required to accomplish this. 2. MPC = .9 AE must decrease by $250 billion to eliminate an inflationary gap. Solve for the change in Government spending required to accomplish this. 3. MPS = .15 AE must increase by $700 million to eliminate a recessionary gap. Solve for the change in Government spending required to accomplish this. 4. MPC = .8 Government spending increases by $500 million. How much does AE increase by? 5. A recessionary gap of $18 billion exists. The SM = 4. How much must Government Spending increase by? 6. An inflationary gap exists of $20 billion. The SM = 4. How much must Government Spending DECREASE by? 7. The MPC is .75. AE must increase by $100 million. How much must Government Spending increase by?

Instead of increasing Government Spending, Congress has chosen to decrease tax rates. Use the tax multiplier (TM) to solve the following.

Change in Taxes x TM = Change in AE

8. The MPC is .75. AE must increase by $100 million. How much should the tax decrease be?

9. The MPS is .1. AE must decrease by $80 million to reduce inflation. How much should the tax INCREASE be?

10. Suppose the government wishes to eliminate an inflationary gap of $100 billion and the MPC is .60. How much must the government increase taxes by?

The long-run aggregate supply curve (LRAS) is Y = Yf, which depends on the amounts of resources and the level of technology innovation. If a country has more resources and better technology, which of the following is true?

		A. The LRAS curve will shift to the right.
		B. The SRAS will shift to the right.
		C. The SRAS will shift to the left.
		D. Only A and B.
		E. Only A and C.

11.

Suppose the wage rates of workers are based on the expected price level. If there is an unexpected increase in AD, it will cause the actual price level to increase. Then workers should raise their expected price level and negotiate a higher wage rate. Then which of the following is most likely to be true when the expected price increases?

		A. The SRAS curve will shift rightward.
		B. The SRAS curve will shift leftward.
		C. The LRAS curve will shift leftward.
		D. Only A and C.
		E. Only B and C.

12.

Suppose the economy is in the long-run equilibrium, i.e., Y = Yf, and there is an unexpected decrease in AD. Assume that Yf is fixed, then which of the following is most likely to be true?

		A. The SRAS curve will shift to the right toward the new long-run equilibrium.
		B. The SRAS curve will shift to the left toward the new long-run equilibrium.
		C. In the new long-run equilibrium, price level will be higher.
		D. Only A and C.
		E. Only B and C.

13.

The short-run (SR) equilibrium is the intersection between AD and SRAS, and long-run (LR) equilibrium is the intersection between AD and LRAS. Every LR equilibrium is a SR equilibrium, but a SR equilibrium is not always the LR equilibrium. If an economy is operating at a SR equilibrium where Y > Yf, which of the following will occur in the process toward the new LR equilibrium when the economy corrects itself?

		A. Price increases.
		B. Real GDP decreases.
		C. Unemployment rate falls.
		D. Only A and B.
		E. Only B and C.

From the Keynesians, Y = C + I + G + NX can be transformed into a theoretical model. In particular, assume that the consumption C = A + mpc (Y-T), where A is a constant, mpc is the marginal propensity to consume, Y is national income and T is income taxes. Suppose in the goods market equilibrium, aggregate expenditure = national income such that the two Y's will be the same from Y = A + mpc (Y-T) + I + G+ NX. . Suppose C = 400 + 0.75(Y â T). G = 100, I = 100, T = 100, and NX = 150, what is the Y in the goods market equilibrium? (All of the variables are in terms of million dollars)

Continue to assume that C = 400 + 0.75 (Y - 100), I = 100, and NX = 150. But the government now increases spending from 100 to 200, how much is the new Y in the goods market equilibrium?

Continue to assume that C = 400 + 0.75 (Y - 100). Then which of the following is true?

		A. The government spending multiplier = 4.
		B. The tax multiplier = 3.
		C. If the government increases spending by $50 million, and at the same time increases taxes by $50 milion to balance the budget, AD will shift to the right by $50 million.
		D. Only A and C.
		E. Only B and C.

Suppose the federal government needs to balance the budget, which means that when the government spending increases, taxes must increase equally. In this case, government spending multiplier is called the balanced-budget multiplier, defined as the increase in real GDP/increase in government spending. By following the example from the previous question, how mcuh is the balanced-budget multiplier?
