Question 1

What are factor costs and how do they relate to GDP?

Accepted Answer

Factor costs include all production expenses such as raw materials, wages, rent, depreciation, and profits incurred by producers. These costs collectively represent the economy's Gross Domestic Product at factor cost, reflecting the total value of goods based on production expenses rather than what consumers actually pay in the market.

Question 2

Why is there a difference between GDP at factor cost and GDP at market price?

Accepted Answer

GDP at factor cost reflects only production expenses, while GDP at market price includes government interventions. Indirect taxes increase prices consumers pay, and subsidies decrease them. This adjustment provides a clearer view of total economic activity from the consumer's perspective, showing what people actually spend on goods and services.

Question 3

How do indirect taxes affect the market price of goods?

Accepted Answer

Indirect taxes are added to the factor cost of goods, raising their market price. For example, bread with a factor cost of $2 and a $0.50 tax has a market price of $2.50. Economists add total indirect taxes to GDP at factor cost when calculating GDP at market price to reflect actual consumer spending.

Question 4

What role do subsidies play in determining market prices?

Accepted Answer

Subsidies lower the market price of goods below their factor cost by reducing what consumers pay. For instance, solar panel installations with a factor cost of $100 and a $20 subsidy cost consumers only $80. Economists subtract total subsidies from GDP at factor cost to calculate the true GDP at market price.

Question 5

How do you calculate GDP at market price from GDP at factor cost?

Accepted Answer

Add total indirect taxes to GDP at factor cost, then subtract total subsidies. For example, with a factor cost of $152, indirect taxes of $5.50, and subsidies of $20, the calculation is: $152 + $5.50 − $20 = $137.50 GDP at market price. This adjustment reflects the actual value of goods from consumers' perspectives.

Question 6

Why do economists adjust GDP for taxes and subsidies?

Accepted Answer

Adjusting GDP for indirect taxes and subsidies provides an accurate reflection of what consumers actually pay for goods and services. This adjustment bridges the gap between production costs and market reality, giving policymakers and analysts a clearer understanding of economic activity and consumer behavior in the economy.

Question 7

What does GDP at market price reveal about an economy?

Accepted Answer

GDP at market price shows the total worth of final goods and services from the consumer's perspective after incorporating government fiscal interventions. It reflects actual market transactions and spending patterns, providing a more complete picture of economic output than factor cost alone, which only considers production expenses.
