How does fiscal policy impact aggregate demand?

• A. By regulating exchange rates
• B. Through changes in government spending and taxation
• C. By controlling inflation rates
• D. Through monetary supply changes

Answer: (B)

Fiscal policy impacts aggregate demand primarily through changes in government spending and taxation. When the government increases spending, it directly injects money into the economy, creating demand for goods and services. This not only stimulates production but also encourages employment as businesses respond to increased demand. On the other hand, changes in taxation affect the disposable income of consumers and businesses. A decrease in taxes allows consumers to spend more, thus boosting aggregate demand. Conversely, an increase in taxes can reduce aggregate demand by leaving consumers with less money to spend.

The focus of fiscal policy is on these direct actions that can be taken by the government to influence economic activity, unlike the regulation of exchange rates or controlling inflation, which are more aligned with monetary policy. Furthermore, while changes in the monetary supply can affect aggregate demand indirectly through interest rates and investment levels, they are not part of fiscal policy's toolkit. Therefore, the correct answer highlights the crucial relationship between government fiscal activities and aggregate demand.
