Which statement best describes GDP?

• A. GDP is the nation's total stock of capital
• B. GDP equals national income
• C. GDP is the total value of final goods and services produced within a country in a given period
• D. GDP measures price stability

Answer: (C)

GDP measures the value, at market prices, of all final goods and services produced within a country’s borders during a specific period. This focus on domestic production and the use of final goods prevents double counting of intermediate stages and aligns with a clear time frame, like a quarter or a year. GDP can be estimated from spending (consumption, investment, government purchases, and net exports), income, or production approaches, and can be reported in nominal or real terms (real GDP accounts for price changes). This makes GDP a standard gauge of economic activity, distinct from the total stock of capital (which is a stock of wealth) and from price stability (which concerns inflation), while related to national income but not identical.
