Inflation, Disinflation, and Deflation

Understanding Inflation

Inflation is a sustained increase in the general price level of goods and services in an economy over a period of time. This means that the purchasing power of money decreases.

KEY TAKEAWAY: Inflation erodes the value of money, making goods and services more expensive.

Measuring Inflation

• The primary measure of inflation in Australia is the Consumer Price Index (CPI), calculated by the Australian Bureau of Statistics (ABS).
• The CPI measures the change in prices of a basket of goods and services consumed by the average Australian household.
• Calculated quarterly.

Disinflation

Disinflation is a decrease in the rate of inflation. Prices are still rising, but at a slower pace than before.

EXAM TIP: Disinflation is often confused with deflation. Remember, disinflation means inflation is slowing down, not becoming negative.

Example of Disinflation

If the inflation rate was 3% last year and is 2% this year, there has been disinflation. Prices are still increasing, but at a slower rate.

Deflation

Deflation is a sustained decrease in the general price level of goods and services. This is the opposite of inflation, and it means the purchasing power of money increases.

COMMON MISTAKE: Deflation might seem beneficial at first, but it can have serious negative consequences for the economy.

Problems with Deflation

• Delayed Consumption: Consumers may delay purchases in anticipation of further price declines, leading to decreased demand.
• Increased Real Debt Burden: The real value of debt increases, making it harder for borrowers to repay loans.
• Reduced Investment: Businesses may postpone investment due to decreased profitability and uncertain future demand.
• Wage Cuts: Firms may reduce wages, further depressing demand.

Why Deflation is Undesirable

Deflation can lead to a deflationary spiral, where falling prices lead to decreased demand, which leads to further price declines, and so on. This can result in a recession or depression.

Comparing Inflation, Disinflation, and Deflation

Impact on Living Standards

• Inflation: Can negatively impact living standards by eroding purchasing power.
• Disinflation: Generally positive as it eases inflationary pressures without causing prices to fall.
• Deflation: Generally negative due to its potential to trigger a deflationary spiral and economic recession, negatively impacting living standards through unemployment and reduced wealth.

APPLICATION: Consider how the COVID-19 pandemic impacted inflation, disinflation, and deflation in Australia.

RBA’s Inflation Target

The Reserve Bank of Australia (RBA) aims to keep inflation between 2-3% per year, on average, over the economic cycle. This target is designed to provide price stability while allowing for some flexibility in the economy.

REMEMBER: The RBA’s inflation target is 2-3%.

Why Not Zero Inflation?

A small amount of inflation is considered healthy for the economy because it:

• Provides a buffer against deflation.
• Allows firms to increase prices without necessarily cutting wages.
• Can stimulate demand.

VCAA FOCUS: VCAA often asks about the consequences of inflation and deflation on different sectors of the economy and different groups of people.
