Q: If the money supply ($$M) is$$ $$\500$ billion, the price level (P$) is 2, and real GDP (Y$) is $$\$$1,000$$ billion, what is the velocity of money ($$V$$)?

$$V = \frac{PY}{M} = \frac{2 \times 1000}{500} = 4$$

Question 1

Suppose the price level $$P$$ increases from 2 to 4. According to the value of money concept, what happens to the value of $1?

Accepted Answer

It decreases from $$\0.50$ to $$\$$0.25 in $$terms of goods.

Question 2

If the money supply ($$M) is$$ $$\500$ billion, the price level (P$) is 2, and real GDP (Y$) is $$\$$1,000$$ billion, what is the velocity of money ($$V$$)?

Accepted Answer

$$V = \frac{PY}{M} = \frac{2 	imes 1000}{500} = 4$$

Question 3

According to the quantity theory of money, if the velocity of money ($$V) is $$stable and real GDP ($$Y) is $$determined by technology and resources, what is the long-run effect of a 10% increase in the money supply ($$M$$)?

Accepted Answer

The price level ($$P) $$increases by 10%.

Question 4

A country experiences hyperinflation when its inflation rate exceeds:

Accepted Answer

50% per month

Question 5

If the government finances its spending by printing money, what is the most likely consequence according to the study materials?

Accepted Answer

An increase in the inflation tax, reducing the value of money held by the public.

Question 6

Which of the following best describes the Fisher Effect?

Accepted Answer

The nominal interest rate adjusts one-for-one with changes in the inflation rate.

Question 7

Suppose the nominal interest rate is 8% and the inflation rate is 3%. What is the real interest rate?

Accepted Answer

$$8\% - 3\% = 5\%$$

Question 8

Which of the following is an example of a 'menu cost' caused by inflation?

Accepted Answer

A restaurant printing new menus to update prices.

Question 9

If actual inflation is higher than expected inflation, who benefits and who loses?

Accepted Answer

Debtors benefit and creditors lose.

Question 10

Which of the following statements about the costs of inflation is correct?

Accepted Answer

Inflation can distort taxes because taxes are based on nominal rather than real income.

Question 11

If the money supply ($$M) $$increases but the real GDP ($$Y) $$and velocity ($$V) $$remain constant, what must happen to the price level ($$P) $$according to the quantity equation $$MV = PY$$?

Accepted Answer

$$P$$ must increase.

Question 12

Which of the following is a 'shoeleather cost' of inflation?

Accepted Answer

The time and effort spent making more frequent bank withdrawals.

Question 13

Suppose the government increases the money supply by 20% in a year, velocity is stable, and real GDP does not change. According to the quantity theory, what is the expected inflation rate?

Accepted Answer

20%

Question 14

Which of the following best explains why inflation acts like a tax on those who hold money?

Accepted Answer

Because inflation reduces the purchasing power of money, making it less valuable.

Question 15

If the price level ($$P) $$doubles and the money supply ($$M) $$remains constant, what happens to the value of money ($$1/P$$)?

Accepted Answer

It is cut in half.

Question 16

Which of the following is NOT a likely consequence of high and unpredictable inflation?

Accepted Answer

Stable and predictable redistribution of wealth.

Question 17

A country has a nominal GDP ($$PY) of$$ $$\2$$,000$$ billion, a money supply (M$) of $$\$$500$$ billion, and a velocity ($$V) of 4. If $$the money supply increases to $$\600$ billion and V$ and Y$ remain constant, what is the new price level (P$)?

Accepted Answer

$$P = \frac{MV}{Y} = \frac{600 	imes 4}{Y}. $$Since $$PY = 2000$$, $$P = \frac{2400}{Y}$$ and $$Y = \frac{2000}{P}. $$Solving, $$P = 2.4$$

Question 18

Which of the following is a common misconception about inflation, according to the 'inflation fallacy'?

Accepted Answer

That inflation erodes real incomes for everyone.

Question 19

If the government prints money to pay for its spending and this leads to hyperinflation, what is the most direct effect on people who hold cash savings?

Accepted Answer

Their savings lose value rapidly.

Question 20

If the inflation rate is unexpectedly low, who is most likely to benefit?

Accepted Answer

Creditors, because the money they are repaid is worth more than expected.
