Which term describes the spending that adds to the circular flow of income through investment, government spending and exports?

• A. GDP
• B. Final Goods
• C. Injections
• D. Deficit Budget

Answer: (C)

Injections are the additions to the circular flow of income that come from outside households. Investment, government spending, and exports are exactly the types of spending that push more money into the economy, boosting overall demand and income as they circulate. In the circular flow, these injections add to the flow by bringing new spending into the economy, unlike withdrawals which pull spending out (such as savings, taxes, or imports). GDP measures overall production, final goods are the end products, and a deficit budget describes a fiscal gap; none of these capture the idea of spending that increases the flow in the economy.
