Question 32

The Fed expands aggregate demand by increasing the money supply and lowering the interest rate.

To stimulate aggregate demand, the Federal Reserve (Fed) implements policies that increase the money supply and lower interest rates, which encourages borrowing and spending by consumers and businesses.

A) Reduce the quantity of reserves

Reducing the quantity of reserves would have the opposite effect of what is needed to expand aggregate demand. By decreasing reserves, banks would have less capacity to lend, leading to a contraction in the money supply and a decrease in overall economic activity.

B) Increase the foreign exchange rate

Increasing the foreign exchange rate typically strengthens the domestic currency, which can lead to decreased exports as they become more expensive for foreign buyers. This would not effectively expand aggregate demand; rather, it may lead to a decrease in demand for domestically produced goods.

C) Raise mortgage rates

Raising mortgage rates would discourage borrowing for home purchases, which would negatively affect the housing market and overall consumer spending. This contraction in credit availability would impede the expansion of aggregate demand, making this option incorrect.

D) Increase the money supply

Increasing the money supply is a primary tool used by the Fed to expand aggregate demand. When the money supply is increased, it lowers interest rates, making loans cheaper and encouraging spending and investment in the economy.

E) Decrease the money supply

Decreasing the money supply would restrict access to credit and lead to higher interest rates, which would reduce spending and investment. This contractionary measure would not support the expansion of aggregate demand but instead would likely lead to a slowdown in economic activity.

F) Lower the interest rate

Lowering the interest rate is another effective method used by the Fed to expand aggregate demand. Lower rates make borrowing cheaper for consumers and businesses, leading to increased spending and investment, which stimulates economic growth.

Conclusion

The Federal Reserve expands aggregate demand primarily through increasing the money supply and lowering interest rates. These actions make borrowing more accessible and encourage spending, which are essential for stimulating economic activity. In contrast, the other options would either restrict lending or negatively impact demand, thereby failing to support the goal of economic expansion.
