Question 3

Two identical countries, Alpha and Beta, can be described by the IS-LM model in the short run. The governments of both countries cut taxes by the same amount. The Central Bank of Alpha follows a policy of holding a constant money supply. The Central Bank of Beta follows a policy of holding a constant interest rate. Compare the impact of the tax cut on income and interest rates in the two countries.

Accepted Answer

The answer of Two identical countries, Alpha and Beta, can...

Question 4

A) always less than in the Keynesian-cross model. 
B) less than in the Keynesian-cross model unless the LM curve is vertical. 
C) less than in the Keynesian-cross model unless the LM curve is horizontal. 
D) less than in the Keynesian-cross model unless the IS curve is vertical.

Question 5

Accepted Answer

A) buy; rises; increase 
B) sell; falls; decrease 
C) sell; rises; decrease 
D) buy; rises; decrease

Question 6

The monetary transmission mechanism in the IS-LM model is a process whereby an increase in the money supply increases the demand for goods and services:

Accepted Answer

A) directly. 
B) by lowering the interest rate so that investment spending increases. 
C) by raising the interest rate so that investment spending increases. 
D) by increasing government spending on goods and services.

Question 7

A decrease in government spending reduces output more in the Keynesian-cross model than in the IS-LM model. Explain why this is true.

Accepted Answer

The answer of A decrease in government spending reduces output...

Question 8

Assume that an economy is described by the IS curve Y = 3,600 + 3G - 2T - 150r and the LM curve Y = 2 M/P + 100r [or r = 0.01Y - 0.02(M/P)]. The investment function for this economy is 1,000 - 50r. The consumption function is C = 200 + (2/3)(Y - T). Long-run equilibrium output for this economy is 4,000. The price level is 1.0 and M = 1,200.
a. Assume that government spending is fixed at 1,200. The government wants to achieve a level of investment equal to 900 and also achieve Y = 4,000. What level of r is needed for I =
900? What levels of T and M must be set to achieve the two goals? What will be the levels of
private saving, public saving, and national saving? (Hint: Check C + I + G = Y.)
b. Now assume that the government wants to cut taxes to 1,000. With G set at 1,200, what will the interest rate be at Y = 4,000? What must be the value of M? What will I be? What will be the levels of private, public, and national saving? (Hint: Check C + I + G = Y.)
c. Which set of policies may be referred to as tight fiscal, loose money? Which set of policies may be referred to as loose fiscal, tight money? Which "policy mix" most encourages investment?

Accepted Answer

The answer of Assume that an economy is described by...

Question 9

Assume that the economy is initially in short-run equilibrium at a level of output above the natural rate. Use the IS-LM model to illustrate graphically how the levels of income and interest rates change as the economy returns to the natural rate of output in the long run.

Accepted Answer

The answer of Assume that the economy is initially in...

Question 10

When bond traders for the Federal Reserve seek to increase interest rates, they bonds, which shifts the curve to the left.

Accepted Answer

A) buy; IS 
B) buy; LM 
C) sell; IS 
D) sell; LM

Question 11

Use the IS-LM model to illustrate graphically the impact of the Pigou effect on the equilibrium level of income and interest rate during the Great Depression, when prices were falling.

Accepted Answer

The answer of Use the IS-LM model to illustrate graphically...

Question 12

If Congress passed a tax increase at the request of the president to reduce the budget deficit, but the Fed held the money supply constant, then the two policies together would generally lead to income and a interest rate.

Accepted Answer

A) lower; lower 
B) lower; higher 
C) no change in; lower 
D) no change in; higher

Question 13

B) LM curve downward and to the right. 
C) IS curve downward and to the left. 
D) IS curve upward and to the right.

Question 14

The LM curve can shift to the right if there is an increase in the supply of money or a fall in the price level. In which case is this movement along the aggregate demand curve and in which case is this a shift of the aggregate demand curve? Explain.

Accepted Answer

The answer of The LM curve can shift to the...

Question 15

Compare the impact of a tax cut on consumption, investment, output, and interest rates in the classical model of Chapter 3 versus the IS-LM model.

Accepted Answer

The answer of Compare the impact of a tax cut...

Question 16

An increase in the demand for money, at any given income level and level of interest rates, will, within the IS-LM framework, output and interest rates.

Accepted Answer

A) increase; lower 
B) increase; raise 
C) lower; lower. 
D) lower; raise

Question 17

An economic change that does not shift the aggregate demand curve is a change in:

Accepted Answer

A) the money supply. 
B) the investment function. 
C) the price level. 
D) taxes.

Question 18

The aggregate demand curve generally slopes downward and to the right because, for any given money supply M a higher price level P causes a real money supply M/P, which the interest rate and spending.
