Chapter 28: Problem 25

Explain how to use quantitative easing to stimulate aggregate demand.

Short Answer

Expert verified

Quantitative easing (QE) stimulates aggregate demand by (1) increasing the money supply and lowering long-term interest rates, making borrowing more attractive, (2) raising asset prices and creating a wealth effect, boosting consumption and investment spending, (3) influencing exchange rates to favor domestic goods and services, promoting exports, and (4) boosting consumer and business confidence, leading to increased spending and investment. These factors work together to increase demand, ultimately supporting economic growth and facilitating the economy's transition out of recessions or periods of slow growth.

Step by step solution

Understand Quantitative Easing

Quantitative easing (QE) is an unconventional monetary policy tool used by central banks when traditional monetary policies such as lowering the policy interest rate is not sufficient to stimulate aggregate demand. In QE, central banks create new money and use it to buy long-term government bonds or other financial assets to increase liquidity in the market. This process effectively increases the money supply and lowers long-term interest rates. The ultimate goal is to encourage borrowing, investment, and spending, ultimately boosting aggregate demand.

Lower Interest Rates

As central banks purchase assets, they inject new money into the financial system. This leads to an increase in the money supply and puts downward pressure on interest rates, including long-term interest rates. Lower interest rates reduce the cost of borrowing and make it more attractive for households and businesses to take out loans for large purchases, such as homes, cars, and new plants or machinery.

Increase Asset Prices

The central bank's purchase of financial assets such as government bonds, corporate bonds, and other securities increases their demand and raises their prices. Higher asset prices create a "wealth effect", as investors holding those assets find their value has increased. This could lead to increased consumption and investment spending, as investors feel wealthier and more confident in their financial situation.

Influence Exchange Rates

Quantitative easing can also have an indirect impact on stimulating aggregate demand through exchange rates. The increased money supply and lower interest rates may lead to depreciation in the domestic currency, which makes domestic goods and services more competitive in the international market. This can boost exports and contribute to aggregate demand.

Boost Consumer and Business Confidence

The actions of central banks during quantitative easing, such as asset purchases and lower interest rates, can boost consumer and business confidence. When consumers and businesses are more confident in the economy, they are more likely to spend and invest, which further increases aggregate demand. This can have a positive feedback effect, reinforcing economic growth and supporting further increases in aggregate demand.

Stimulate Aggregate Demand

The combination of lower interest rates, increased asset prices, depreciation of the domestic currency, and improved consumer and business confidence works to stimulate aggregate demand. This increased demand leads to higher levels of output, income, and employment in the economy. By stimulating aggregate demand, quantitative easing aims to support economic growth and help the economy transition out of recessions or periods of sluggish growth.
