What best describes the multiplier effect?

• A. A chain reaction where increased spending leads to further economic activity.
• B. A single investment impact.
• C. A policy that reduces government spending.
• D. A temporary phenomenon with no long-term effects.

Answer: (A)

The multiplier effect describes how an initial amount of spending sets off a chain reaction in the economy. When someone spends money, that money becomes income for someone else, who then has more to spend. A portion of each successive round is spent again, and so on, so the total rise in national income is larger than the original amount spent. How big the boost is depends on how much people tend to spend out of extra income (the marginal propensity to consume) and on factors that take money out of circulation, like saving, taxes, and imports. So the idea of a chain reaction of spending that leads to more economic activity best captures the multiplier effect. The other options describe a one-off impact, a policy that cuts spending, or a temporary change with no lasting effects, which don’t reflect this amplification through repeated rounds of spending.
