Monetary Policy Study Notes

Daily Review

Improving living standards is a key economic goal because a higher living standard leads to a stronger and more prosperous nation. When citizens are employed and earning an income, they can purchase more goods and services. Governments constantly make economic policy decisions to improve economic growth and living standards.

Monetary Policy

Key Questions

  1. What is monetary policy?
  2. Why does the Reserve Bank of Australia (RBA) use expansionary and contractionary policies?

Learning Objective

Explain how monetary policy influences economic growth and identify examples used during COVID-19.

Success Criteria

  • Identify scenarios for using expansionary or contractionary policies.
  • Describe examples of economic policy during COVID-19.

Macroeconomic Policy

Macroeconomic policies affect the whole nation; monetary policy is an example. Monetary policy sets the cash rate, affecting interest rates for consumers and businesses.

Key Points

  1. Definition: Macroeconomic policies affect the entire nation.
  2. Example: Monetary policy is a macroeconomic policy.
  3. Explanation: Monetary policy influences economic growth and living standards by setting the cash rate, which affects interest rates for consumers and businesses.

Drivers of Economic Growth

Investment, government spending, exports, and consumption drive economic growth (GDP). Consumption is the largest driver, mainly determined by consumers' disposable income.

Consumption

  • Disposable income: Money left after tax.

Monetary Policy Defined

Monetary policy involves the Reserve Bank manipulating the cash rate to influence the economy. The cash rate is the interest rate for overnight loans between commercial banks, influencing other interest rates, borrowing, spending, and economic activity.

Interest Rates and Consumption

The cost of borrowing, i.e., interest rates, significantly influences consumption levels. Monetary policy aims to achieve sustainable growth, targeting unemployment at 5-6% and inflation at 2-3%.

Implementation of Monetary Policy

The Reserve Bank monitors domestic and international economic conditions, assessing leading economic indicators and the economy's position in the business cycle. The board meets monthly to review these indicators and announce the cash rate, influencing market interest rates.

Transmission Mechanism

The transmission mechanism describes how changes in the cash rate affect economic growth. Changes in the cash rate lead to changes in interest rates, which in turn affect consumption, influencing economic activity (GDP, employment, and inflation).

Expressed mathematically, we can represent the relationships as follows:

\text{Cash Rate} \uparrow \rightarrow \text{Interest Rates} \uparrow \rightarrow \text{Consumption} \downarrow \rightarrow \text{Economic Activity} \downarrow

\text{Cash Rate} \downarrow \rightarrow \text{Interest Rates} \downarrow \rightarrow \text{Consumption} \uparrow \rightarrow \text{Economic Activity} \uparrow

Expansionary Policy Example

John earns 20,000. He borrows 100,000 for a house at 10% interest, paying back 10,000 annually, leaving 10,000 to spend. With an expansionary policy, the cash rate drops, and John's interest rate falls to 5%. Now, he pays back 5,000 annually, leaving 15,000 to spend, driving economic growth.

Contractionary vs. Expansionary Policy

The Reserve Bank adopts a contractionary stance when the economy is overheated, increasing the cash rate to raise interest rates and decrease consumption. Conversely, it adopts an expansionary stance when economic activity slows, decreasing the cash rate to stimulate the economy.

Types of Policy

  • Contractionary: Used when the economy is growing too fast.
  • Expansionary: Used when economic activity slows.

Potential Problem with Monetary Policy

A cartoon shows the Reserve Bank cutting interest rates, but banks not passing those cuts onto credit card interest rates, indicating a potential problem with monetary policy effectiveness.

Stance Scenarios

Determine whether to take an expansionary, contractionary, or neutral stance based on economic growth, unemployment, and inflation targets:

  • Economic growth: 3-4%
  • Unemployment: 5-6%
  • Inflation: 2-3%

Lesson Closure

  • Monetary policy involves manipulating the cash rate to influence the economy.
  • The aim is to achieve sustainable growth.
  • Factors driving economic growth include investment, government spending, exports, and consumption.

Three Stances of the RBA

  1. Expansionary: Lower the cash rate to lower interest rates and stimulate consumer spending.
  2. Contractionary: Increase the cash rate to increase interest rates and lower consumer spending.
  3. Neutral: Maintain interest rates to maintain consumer spending.
