New cards

The fact that many stores in the United States now accept credit cards has

decreased the demand for money

2
New cards

A decrease in the demand for money would result from:

a decrease in the price level

3
New cards

If inflation increases from 2% to 5%, the money demand curve will:

Shift to the right

4
New cards

The Federal Reserve affects interest rates by:

open market operations that shift the money supply curve.

5
New cards

If the Federal Reserve wants to lower the interest rate, it will:

increase the money supply.

6
New cards

If the target rate of interest is higher than the current equilibrium interest rate, the Federal Reserve will:

7
New cards

A rise in interest rates due to a decrease in the money supply will _______ AD.

Reduce

8
New cards

To close a recessionary gap using monetary policy, the Federal Reserve should ________ the money supply to ________ investment and consumer spending and shift the aggregate demand curve to the ________.

increase; increase; right

9
New cards

What is the goal of expansionary monetary policy, and how does it work in the short run? Explain all the steps in the process. Start with the initial action by the Fed and end with the change to AD.

The goal of expansionary monetary policy is to increase spending. To do this the Fed wants to increase the money supply. So, they set a lower target for the fed funds int. rate and to achieve this target, they start buying bonds which will get more cash into the banking system. When banks have more cash, they then make more loans. Thus, businesses will take out more loans from banks at the more attractive lower interest rate and investment spending will increase. This increased investment spending becomes someone's income who then increase consumption spending. Both this increase in I and C increase AD (spending).

When the Federal Reserve decreases bank's reserves through an open-market operation:

the monetary base decreases, loans decrease, and the money supply decreases

21

New cards

According to the wealth effect, when prices decrease, the purchasing power of assets:

technological progress.

84
New cards

Which of the following will NOT increase the productivity of labor?

When tracking economic growth, why do economists prefer real GDP per capita over: a. real GDP?

It accounts for population size and gives a rough measure for the income of an average person in the country.

92
New cards

When tracking economic growth, why do economists prefer real GDP per capita over: nominal GDP per capita?

It accounts for inflation so that comparisons can be made over time

93
New cards

Many impoverished nations struggle with diseases like malaria. How would a reduction or the elimination of malaria contribute to long-run economic growth?
