What is a direct effect of an increase in the multiplier?

An increase in the multiplier results in a greater overall impact on economic output in response to an initial increase in spending. The multiplier effect occurs when an initial amount of spending leads to a chain reaction of further spending and income generation within the economy.

For example, if the government increases its expenditure on infrastructure projects, the initial spending provides income for contractors and workers. Those individuals then spend a portion of their income on goods and services, which further stimulates economic activity. A higher multiplier means that this initial increase in spending leads to a larger increase in overall economic output than would occur with a smaller multiplier. Consequently, the economy benefits from heightened levels of activity, leading to increased production, higher employment levels, and overall growth.

In contrast, the other options do not relate directly to the multiplier effect. An increase in aggregate demand is a consequence of the multiplier; a reduction in savings rates might happen depending on consumer behavior, but it is not a direct result of the multiplier itself; and an increase in unemployment rates would typically indicate weakening economic conditions, which contradicts the positive outcomes associated with a larger multiplier. Therefore, a higher multiplier directly correlates with an increase in overall economic output.
