Q: Suppose a household earns $$\80$$,000$$ in wages, receives $$\$$5,000 in $$interest, and pays $$\15$$,000$ in taxes. What is the household's disposable income?

$$\70$$,000$$ $$\text{Disposable Income} = \text{Wages} + \text{Interest} - \text{Taxes} = 80,000 + 5,000 - 15,000 = 70,000$

Q: If the nominal interest rate is $$8\%$$ and the inflation rate is $$3\%$$, what is the real interest rate?

$$5\%$$ $$\text{Real Interest Rate} = \text{Nominal Interest Rate} - \text{Inflation Rate} = 8\% - 3\% = 5\%$$

Question 1

Which of the following best describes the difference between gross investment and net investment?

Accepted Answer

Gross investment is the total amount spent on new capital, while net investment is gross investment minus depreciation.

$$	ext{Net Investment} = 	ext{Gross Investment} - 	ext{Depreciation}$$

Question 2

Suppose a household earns $$\80$$,000$$ in wages, receives $$\$$5,000 in $$interest, and pays $$\15$$,000$ in taxes. What is the household's disposable income?

Accepted Answer

$$\70$$,000$$

$$	ext{Disposable Income} = 	ext{Wages} + 	ext{Interest} - 	ext{Taxes} = 80,000 + 5,000 - 15,000 = 70,000$

Question 3

Which of the following is NOT a characteristic of a bond?

Accepted Answer

It represents ownership in a corporation.

Question 4

If the nominal interest rate is $$8\%$$ and the inflation rate is $$3\%$$, what is the real interest rate?

Accepted Answer

$$	ext{Real Interest Rate} = 	ext{Nominal Interest Rate} - 	ext{Inflation Rate} = 8\% - 3\% = 5\%$$

Question 8

If the present value of $$\1$$,000$$ to be received in 3 years at an interest rate of 5$$\%$ is calculated, which formula should be used?

Accepted Answer

$$PV = \dfrac{FV}{(1 + r)^n}$$

$$PV = \dfrac{1,000}{(1 + 0.05)^3$}$$
