The correct option is 1 and 3 only.
Explanation
Gross Domestic Product (GDP) represents the total monetary value of all final goods and services produced within the economic territory of a country during a specific period, typically a year. A critical aspect of GDP estimation is distinguishing between final goods and intermediate goods to ensure accurate measurement of economic activity.
Statement-wise Analysis
- Statement 1 is Correct. GDP is defined as the aggregate market value of all final goods and services produced within the domestic territory of a country during a financial year. It focuses on "final" goods to represent the ultimate consumption or investment within the economy.
- Statement 2 is Incorrect. The value of a final good includes the value of all intermediate goods used in its production. For example, the price of a loaf of bread (final good) covers the cost of flour, yeast, and fuel (intermediate goods) used to make it. If the value of intermediate goods were excluded from the final good's price, the remaining amount would only represent the "value added" at the final stage, not the full value of the final good.
- Statement 3 is Correct. Counting the value of intermediate inputs (like wheat and flour) separately, in addition to the value of the final product (biscuits), results in double counting. Since the value of the biscuit already incorporates the cost of the wheat and flour, counting them again separately would inflate the national income estimates artificially.
Key Takeaway: To avoid the error of double counting, GDP calculations consider only the market value of final goods (which inherently includes the value of intermediate inputs) or sum the value added at each stage of production.
