Q

If the consumption function is given by C = 100 + 0.75(Y-T), then an increase of 10 units in taxes will cause the IS schedule to shift to the right by

A

-30 units.

29
Q

A decline in the money stock will

A

shift the LM schedule to the right.

30
Q

In the Keynesian theory, an exogenous decrease in the demand for money shifts

A

the LM curve to the left.

31
Q

An decrease in the velocity of money for given levels of income and the interest rate would shift the

A

LM curve up.

32
Q

If the consumption function is given by C = 200 + 0.6YD, then an increase in taxes of 50 units will cause the IS schedule to

A

shift to the left by 75 units.

33
Q

If the money demand function is given by Md = 10 + 0.2Y ? 10r then a 10-unit increase in the quantity of money will cause the LM schedule to shifts to

A

the right by 50 units.

34
Q

If the MPC is 0.6, then a 50-unit rise in taxes and a 50-unit rise in government spending will shift the IS curve

A

to the right by 50 units.

35
Q

According to Keynes’ theory of money demand, a low interest rate increases the likelihood of a capital ________ and ______ the interest elasticity of money demand.

A

loss on bonds; reduces.

36
Q

The LM curve slopes upward because

A

as income increases, money demand rises, which increases interest rates.

37
Q

Assume that the economy is presently in equilibrium. A decline in the interest rate

A

increases planned investment, aggregate demand, and equilibrium income.

38
Q

The IS curve slopes upward because

A

as income rises, savings rise and consumption falls, decreasing output.

39
Q

Along any IS curve

A

both government spending and expectations are fixed.

40
Q

Assume that you purchased a $1,000 perpetual bond that pays a market interest rate of 5 percent. If you attempted to sell this bond today subsequent to an increased market rate of interest of 7.5 percent, then you

A

could only sell this bond at a capital loss.

41
Q

According to the Keynesian model of the money market, the supply of money

A

is chosen by the central bank.

42
Q

In the Keynesian theory of money demand,

A

money is held in part because it is an asset.

43
Q

The intuition behind the slope of the LM curve is that

A

as income increases, money demand increases which increases interest rates.

44
Q

At any point on the LM curve

A

money supply equals money demand.

45
Q

If Y>C+I+G but Md= Ms, then

A

both interest rates and output must fall.

46
Q

A decrease in the price level, holding the nominal money supply constant, will shift the LM curve

A

upward and to the right.

47
Q

Panel (a) in Figure 6.1 depicts

A

low interest elasticity of money demand.

48
Q

Panel (b) in Figure 6.1 reflects

A

money demand to be highly interest elastic.

49
Q

The IS curve represents

A

all points where there is no excess demand or excess supply.

50
Q

Assuming that money demand is completely interest insensitive, the

A

LM schedule will be vertical.

51
Q

In the IS-LM model, the two variables that are affected by the interest rate are

A

money demand and investment spending.

52
Q

Points to the left of the LM schedule show that

A

the amount of money supplied exceeds the amount of money demanded.

53
Q

If the current interest rate increases,

A

there is a movement along the money demand curve and the money supply curve remains unchanged.

54
Q

Points to the right of the IS schedule indicate that

A

saving plus taxes will exceed investment plus government spending.

55
Q

In the Keynesian system, an increase in the money stock would

A

decrease the interest rate, which, in turn, would increase aggregate demand and incom

56
Q

One of the most responsive components of investment to changes in interest rates are

A

residential housing.

57
Q

If Md = 1,000 - 400r and Ms = 2,000, the MPC = .85, G=100, and T = 120, then the equilibrium interest rate is

A

2.5

58
Q

If Md = 2,600 - 200r, the MPC = .75, G=100, and T = 100. If the central bank wants the interest rate to be r=2, then the money supply must be

A

3,000

59
Q

If the central bank follows a monetary policy in which it maintains a fixed interest rate, then

A

the LM curve will become horizontal.

60
Q

If savings does not depend upon the interest rate, then

A

the IS curve is still downward sloping.

61
Q

With respect to the Keynesian liquidity trap, at very low levels of income, equilibrium in the money market occurs at points along the flat portion of the money demand schedule where

A

the elasticity of money demand is extremely high.

62
Q

If Y=C+I+G but Md< Ms, then

A

interest rates must fall and output must rise.

63
Q

In the classical model,

A

neither fiscal nor monetary policy can influence output.

64
Q

If money demand is not responsive to changes in interest rates, then

A

the LM curve is vertical.

65
Q

A relatively steep money demand schedule reflects the assumption that the interest elasticity of money demand is

A

low (in absolute value).

66
Q

Which of the following is true about the LM curve?

A

The LM cuve slopes upward for a given level of the money supply.

67
Q

If the money supply increases at the same time that taxes increase, then:

A

interest rates will definitely decrease.

68
Q

The IS curve will shift to the right if:

A

taxes decrease.

69
Q

If the economy is in a liquidity trap, then:

A

monetary policy cannot stimulate the economy by lowering interest rates.
