Q: Suppose the money supply ($$M) is$$ $$2000$$, the price level ($$P) is$$ $$5$$, and real GDP ($$Y) is$$ $$800. $$What is the velocity of money ($$V$$)?

$$V = \frac{5 \times 800}{2000} = 2$$

Q: Suppose you deposit $1000 in a bank for one year. The nominal interest rate is 10%, inflation is 0%, and the tax rate is 25%. What is your after-tax real interest rate?

10% \times (1 - 0.25) = 7.5%, real interest rate = 7.5% - 0% = 7.5%

Question 1

According to the quantity theory of money, what is the primary cause of long-run inflation?

Accepted Answer

Excessive growth in the money supply

Question 2

If the price level $$P$$ increases from $$2 to$$ $$3$$, what happens to the value of money $$1/P$$?

Accepted Answer

It decreases from $$1/2 to$$ $$1/3$$

Question 3

Which equation represents the velocity of money?

Accepted Answer

$$V = \frac{P 	imes Y}{M}$$

Question 4

Suppose the money supply ($$M) is$$ $$2000$$, the price level ($$P) is$$ $$5$$, and real GDP ($$Y) is$$ $$800. $$What is the velocity of money ($$V$$)?

Accepted Answer

$$V = \frac{5 	imes 800}{2000} = 2$$

Question 5

If the Federal Reserve increases the money supply, what is the expected effect on the price level and the value of money?

Accepted Answer

Price level rises, value of money falls

Question 6

Given the quantity equation $$M 	imes V = P 	imes Y$$, if $$V$$ and $$Y$$ are constant, what happens to $$P if$$ $$M$$ increases by 10%?

Accepted Answer

$$P$$ increases by 10%

Question 7

Which of the following best describes 'shoeleather costs'?

Accepted Answer

The resources wasted when people reduce their money holdings due to inflation

Question 8

In the context of inflation, what is the 'inflation tax'?

Accepted Answer

The reduction in the value of money held by the public when the government prints more money

Question 9

According to the Fisher effect, if the inflation rate increases by 3 percentage points, what happens to the nominal interest rate?

Accepted Answer

It increases by 3 percentage points

Question 10

Suppose you deposit $1000 in a bank for one year. The nominal interest rate is 10%, inflation is 0%, and the tax rate is 25%. What is your after-tax real interest rate?

Accepted Answer

10% 	imes (1 - 0.25) = 7.5%, real interest rate = 7.5% - 0% = 7.5%

Question 11

Which of the following is NOT a cost of inflation discussed in the study materials?

Accepted Answer

Increase in real wages

Question 12

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

Accepted Answer

Debtors benefit, creditors lose

Question 13

In Zimbabwe, hyperinflation was primarily caused by:

Accepted Answer

Large government budget deficits financed by printing money

Question 14

Which statement about the long-run effects of inflation is correct?

Accepted Answer

Real incomes are determined by real variables, not the inflation rate

Question 15

If the money supply increases by 5% and real GDP increases by 3%, with velocity constant, what is the approximate inflation rate?

Accepted Answer

2%

Question 16

Which of the following best describes 'menu costs'?

Accepted Answer

The cost of changing prices, such as printing new menus or catalogs

Question 17

If the government finances its spending by printing money, what is the likely result according to the quantity theory?

Accepted Answer

Inflation tax and rising prices

Question 18

Which formula correctly rearranges the definition of the real interest rate?

Accepted Answer

$$	ext{Nominal interest rate} = 	ext{Inflation rate} + 	ext{Real interest rate}$$

Question 19

If taxes are based on nominal income rather than real income, what is a consequence during periods of inflation?

Accepted Answer

People pay more tax even if their real income does not increase

Question 20

Which of the following is true about the velocity of money?

Accepted Answer

It is the rate at which money changes hands in the economy
