Question 1

What does the income approach measure in calculating GDP?

Accepted Answer

The income approach measures GDP by summing all income earned from producing goods and services, including wages, rents, interest, and profits. It shows how the total value of production is distributed among the factors of production within a country during a specific period.

Question 2

Why are indirect taxes added when converting national income to GDP at market prices?

Accepted Answer

Indirect taxes, such as sales tax, increase the market prices consumers pay for goods and services. Since GDP measures the value at market prices rather than factor cost, these taxes must be added to national income to reflect what people actually pay in stores.

Question 3

How does depreciation factor into the income approach calculation?

Accepted Answer

Depreciation accounts for the wear and tear on capital goods like machinery and tools over time. Adding depreciation ensures the measurement reflects gross production rather than net production, capturing the actual cost of maintaining productive capacity and keeping production going.

Question 4

What role do subsidies play in adjusting national income to market prices?

Accepted Answer

Subsidies are government payments that lower the market prices of goods and services. Since these payments are not part of actual production value, they are subtracted from national income when converting to GDP at market prices to avoid overstating the true value produced.

Question 5

Why is net factor income from abroad subtracted in the income approach?

Accepted Answer

Net factor income from abroad represents the difference between income a country earns internationally and income it pays abroad. Subtracting this adjustment ensures GDP reflects only income generated within the domestic territory, distinguishing it from gross national income earned globally.

Question 6

How does the income approach differ from measuring GDP at factor cost versus market price?

Accepted Answer

National income is measured at factor cost, reflecting only production costs. To convert to GDP at market prices, adjustments for indirect taxes, subsidies, and depreciation are applied. This transformation accounts for the difference between what producers earn and what consumers actually pay.

Question 7

What components of income are included when calculating GDP by the income method?

Accepted Answer

The income method includes wages earned by workers, rent paid for land and property, interest received on capital, and profits earned by businesses. Together, these income components represent how the total value of goods and services produced is distributed among all factors of production.
