Q: Which equation represents the money multiplier in a fractional-reserve banking system?

$$\text{Money Multiplier} = \frac{1}{\text{Reserve Ratio}}$$

Question 1

Which of the following best describes the relationship shown in the first image, where the nominal interest rate decreases as the quantity of money increases?

Accepted Answer

The demand for money curve, which shows a negative relationship between the nominal interest rate and the quantity of money demanded.

Question 2

Refer to the second image. If the Federal Reserve increases the money supply, which of the following will most likely occur?

Accepted Answer

The vertical money supply curve (MS) will shift right, leading to a lower equilibrium nominal interest rate.

Question 3

In the third image, the money supply curve shifts from $$MS_0 to$$ $$MS_1. $$What is the most likely cause of this shift, and what is its effect on the equilibrium interest rate?

Accepted Answer

The Fed sells government securities, decreasing the money supply and raising the equilibrium interest rate.

Question 4

Which equation represents the money multiplier in a fractional-reserve banking system?

Accepted Answer

$$	ext{Money Multiplier} = \frac{1}{	ext{Reserve Ratio}}$$

Question 5

In the fourth image, what does the intersection of the money supply curve ($$MS) $$and the money demand curve ($$MD) $$represent?

Accepted Answer

The equilibrium value of money, where the quantity of money demanded equals the quantity supplied.

Question 6

Which of the following is NOT included in the official measure of money known as $$M_1$$?

Accepted Answer

Savings deposits

Question 7

If the government runs a budget deficit, what is the most likely effect on the market for loanable funds, as shown in the fifth image?

Accepted Answer

The supply curve for loanable funds shifts left, increasing the equilibrium interest rate and decreasing the equilibrium quantity of funds.

Question 8

Which equation represents the equation of exchange in the quantity theory of money?

Accepted Answer

$$M 	imes V = P 	imes Y$$

Question 9

In the sixth image, what happens to the equilibrium interest rate and quantity of loanable funds if the supply curve shifts right from $$S_1 to$$ $$S_2$$?

Accepted Answer

The equilibrium interest rate falls and the equilibrium quantity of loanable funds rises.

Question 10

If the Federal Reserve increases the required reserve ratio, what is the most likely effect on the money supply?

Accepted Answer

The money supply decreases because banks must hold more reserves and can lend less.

Question 11

Which of the following best describes 'crowding out' in the context of government budget deficits?

Accepted Answer

A decrease in investment that results from government borrowing, raising interest rates.

Question 12

Which of the following is a function of money that eliminates the need for barter?

Accepted Answer

Medium of exchange

Question 13

If the price level doubles, what happens to the quantity of money demanded, according to the demand for money curve?

Accepted Answer

The quantity of money demanded doubles.

Question 14

Which of the following is NOT considered money according to the study materials?

Accepted Answer

Credit cards

Question 15

If the government introduces an investment tax credit, what is the most likely effect on the market for loanable funds?

Accepted Answer

The demand curve for loanable funds shifts right, increasing the equilibrium interest rate and quantity of funds.

Question 16

Which of the following best describes the effect of a budget surplus on the market for loanable funds?

Accepted Answer

The supply of loanable funds increases, the equilibrium interest rate falls, and investment rises.

Question 17

Which formula correctly expresses private saving in a closed economy?

Accepted Answer

$$	ext{Private Saving} = Y - T - C$$

Question 18

What is the primary advantage of a mutual fund for individual investors?

Accepted Answer

It allows individuals with small amounts of money to diversify their investments.

Question 19

Which of the following is true about the supply of money curve in the money market?

Accepted Answer

It is vertical because the quantity of money supplied is fixed on any given day.

Question 20

According to the quantity theory of money, what happens if the quantity of money increases by 10% while real GDP remains at potential GDP?

Accepted Answer

The price level increases by 10%.
