Document Summary

Write all answers neatly and legibly: use the short-run keynesian model to answer this set of questions. C = 10 + . 8(y t) where c is consumption spending, y is real gdp, and t is taxes. G = 10 where g is government spending. I = 10 where i is planned private investment spending. So, sp = -10 + . 2(y 20) = -14 + . 2y. Sp = -14 + . 2y: (1 point) given the above information calculate the equilibrium values of y and c for this economy. Put your final answer in the provided blanks. Ae = c + i + g + (x im) Ae = 10 + . 8(y t) + 10 + 10 + 5. So, y = 35 + . 8(y 20) If ye = 95, then c = 10 + . 8(y 20) Ce = 70: (1 point) suppose the government increases its level of government spending to 30 (g".

Consider an open economy in which the real exchange rate is fixed and equal to one. Consumption, Investment, and Government spending are given by:

C=10+0.8(Y-T), I=10, G=10, and T=10, IM=0.3Y and X=0.3Y* where Y* denotes foreign output.

A) Solve for equilibrium output in the domestic economy

B) Given Y* what is the multiplier in this economy? If we were to close the economy-so exports and imports were identically equal to zero-what would the multiplier be? Why would the multiplier be different in a closed economy?

The Modified Keynesian Model

Y = C + I + G + X â IM â¦ equilibrium condition in a 4-sector model where:

C = 150 + 0.9DI â¦ consumption function

I = 50 â¦ autonomous investment

G = 100 â¦ autonomous government spending

X = 200 â¦ autonomous exports

IM = 100 â¦ autonomous imports

And also:

DI = Y â T + Tr T = 0 â¦ autonomous taxes

Tr = 0 â¦ autonomous transfer payments

YF = 5000 â¦ full-employment Y

1. Solve for the equilibrium level of real output/income (Y*) in this economy.

2. Given the model above, net exports equal $________. Does this represent a trade deficit or trade surplus?

3. Given the model above, the federal budget has a (deficit/surplus) equal to $________.

4. What is the value of the MPC? â¦ the value of the MPS?

5. Calculate the âoversimplifiedâ expenditure multiplier.

6. Suppose that full-employment (YF) equals $5000. Is there a recessionary or inflationary output gap?

7. (Refer to question â6â.) How much is the gap equal to?

8. Suppose the government chooses to eliminate the gap by using expansionary fiscal policy (i.e., increasing G). Given the numbers above, by how much would government spending (G) need to increase to achieve the goal of full-employment?

9. Suppose instead that the government decided to lower taxes to eliminate the output gap in question â6â. How much would taxes need to fall to achieve the goal of full-employment?

10. Which action (raising G or lowering T) has the largest effect on the federal budget deficit and the national debt?

11. Suppose the national debt equaled $6000 before the tax cut (refer to question â9â). What would be the value of the national debt after this policy action?

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
