Questions this Monetary policy deck will help you answer

Definition Flip

Key Concept Flip

What is the main objective of monetary policy in most countries?

Answer Flip

The primary objective is typically to maintain price stability by controlling inflation. Many central banks operate with an explicit inflation target (

Example: 2% inflation rate).
Key Concept Flip

Explain how an increase in interest rates can help to control inflation.

Answer Flip

Higher interest rates increase the cost of borrowing, discouraging consumer spending and business investment. This reduces aggregate demand, which helps to lower inflationary pressures in the economy.

Definition Flip

What is the role of the central bank in implementing monetary policy?

Answer Flip

The central bank is responsible for setting interest rates, managing the money supply, and overseeing the banking system. It acts as the lender of last resort and implements policies to maintain financial stability.

Key Concept Flip

Describe the relationship between the money supply and inflation.

Answer Flip

An increase in the money supply, without a corresponding increase in output, typically leads to inflation. More money chasing the same amount of goods and services drives up prices.

Definition Flip

What is quantitative easing (QE) and why might a central bank use it?

Answer Flip

QE involves a central bank injecting liquidity into the economy by purchasing assets, such as government bonds. It's used when interest rates are already near zero and further stimulus is needed to boost economic activity.

Key Concept Flip

How might a central bank lower interest rates to stimulate economic growth?

Answer Flip

A central bank can lower the base interest rate, which influences the interest rates charged by commercial banks to consumers and businesses. This makes borrowing cheaper, encouraging spending and investment.

Key Concept Flip

Explain one limitation of using monetary policy to control inflation.

Answer Flip

Monetary policy operates with a time lag, meaning it takes time for changes in interest rates to affect the economy. This makes it difficult to fine-tune the economy and can lead to unintended consequences.

Key Concept Flip

How does an inflation target help to manage inflation expectations?

Answer Flip

An inflation target provides a clear benchmark for price stability, influencing expectations among consumers and businesses. If people believe the central bank will achieve the target, it makes it easier to manage inflation.
