Question 8

Which of the following is NOT included in the calculation of GDP using the income approach?

Accepted Answer

The value of intermediate goods purchased by firms.

Question 9

A country’s GDP is measured at $1 trillion using the expenditure approach. According to the fundamental identity, what should be the GDP measured by the income approach?

Question 10

Which of the following statements about the product approach to measuring GDP is correct?

Accepted Answer

Question 11

Suppose a car manufacturer buys steel for $$5,000 and sells a car for 20$$,000. If the steel was produced domestically, what is the value added by the car manufacturer?

Accepted Answer

$$\$50,000$$

Question 14

Why is it important to use value added rather than total output when measuring GDP using the product approach?

Accepted Answer

To avoid double counting the value of intermediate goods.

Question 15

Which of the following is a real-world example of the expenditure approach to GDP measurement?

Accepted Answer

Summing all household purchases of goods and services in a year.

Question 16

If a country’s GDP is measured using the product approach and found to be $$800 billion, but the sum of all incomes is only 750 $$billion, what is the most likely explanation?

There is incomplete or misreported data in the income approach.

Question 17

Which of the following best illustrates the unified approach to macroeconomics?

Accepted Answer

Using models to connect and explain relationships among different economic variables.

Question 18

Accepted Answer

$$\$1,000\ 	ext{billion}$$
