Which statement best describes the difference between leakages and injections?

• A. Injections remove money; leakages add money
• B. They move money in opposite directions
• C. The two concepts are unrelated
• D. Leakages remove money; injections add money

Answer: (D)

In the circular flow of income, leakages are withdrawals from the spending stream that reduce the money circulating in the domestic economy—think saving, taxes, and imports. Injections are additions to that same stream—investment, government spending, and exports—that bring money back into the economy. The difference described here is that leakages remove money from the circular flow, while injections add money to it. This distinction is the clearest way to capture how the economy’s spending and production are influenced by these two processes. The other statements either reverse the directions, imply only an opposite movement without the core idea, or claim there’s no relationship, all of which don’t accurately convey how leakages and injections operate. When injections exceed leakages, overall income tends to rise; when leakages exceed injections, it tends to fall.
