Money entering the economy through investment, government spending, and exports is called

• A. Globalisation
• B. Injections
• C. Open economy
• D. Leaks

Answer: (B)

The main concept here is injections into the circular flow of income. Injections are additions to domestic spending that come from outside the simple household–firm spending loop. Investment adds to capital formation and spending in the economy, government purchases goods and services, and exports bring in spending from foreigners on domestically produced goods. Together, these injections increase aggregate demand and raise overall income and output. They contrast with leakages—taxes, saving, and imports—that drain spending from the economy unless offset by injections. Globalisation and an open economy describe broader trade contexts, not the specific mechanism of money entering the economy through these channels.
