10 Economics EXAM

The Business Cycle

The business cycle describes the natural rise and fall of economic activity over time. Measured using real GDP

Benefits of understanding the business cycle

Understanding these movements helps governments, businesses and households make informed decisions about spending, saving, hiring and investing.

The four phases

They always occur in the same order and repeat continuously, though the length and intensity of each phase varies. Includes expansion, Peak, Contraction, and though

 Expansion

During an expansion, the economy is growing. Gross Domestic Product (GDP) increases, businesses produce more goods and services, and consumer confidence rises.

•      Rising employment and falling unemployment

•      Inflation generally begins to rise as demand strengthens

•      Higher business confidence and new business creation

Peak

The peak is the highest point of economic activity in the cycle. The economy is operating at or near full capacity. While this sounds positive, peaks are unsustainable and often signal that a downturn is approaching.

•      High inflation as demand outpaces supply

•      Resource shortages and rising wages

•      Maximum production and consumer spending

Contraction

A contraction occurs when economic activity declines. If the contraction is significant and lasts for two consecutive quarters (six months) of negative GDP growth, it is officially called a recession.

•      Declining consumer spending and confidence

•      Rising unemployment as businesses cut costs

•      Reduced business investment

Trough

The trough is the lowest point of the business cycle. Economic activity has bottomed out and is ready to begin recovering.

•      Highest unemployment of the cycle

•      Central banks typically lower interest rates to stimulate the economy

Relationship Between Recessions and Contractions

All recessions are contractions, but not all contractions are recessions. A contraction is any period where economic activity declines.

A recession is a specific, more severe type of contraction defined by two consecutive quarters of negative GDP growth.

Economic Indicators defintion

Economic indicators are statistics that give us information about the health and direction of the economy. They are used by governments, businesses, investors and households to make decisions about the future.

examples of economic indicators (3 main ones)

GDP (Gross Domestic Product)- Total value of all goods and services produced in a country in a given period. Tells us the overall size and growth of the economy

Inflation Rate- Change in the average price of goods and services over time. Tells us Whether the cost of living is rising or falling

Unemployment Rate- Percentage of the labour force that is unemployed and actively seeking work. Tells us Labour market health and job availability

Interpreting Economic data

When you see economic data in graphs or tables, look for:

•      Trends — Is the indicator rising, falling or stable over time?

•      Magnitude — How large is the change? A 0.1% rise is very different from a 5% rise.

•      Comparisons — How does it compare to previous periods, target ranges, or other countries?

•      Context — What was happening in the economy during this period (e.g., COVID-19, global financial crisis)?

GDP defintion

Gross Domestic Product (GDP) is the total monetary value of all final goods and services produced within a country during a specific period. (usually a quarter or year). It is the most widely used measure of an economy's size

Sustainable Economic Growth

Sustainable economic growth is growth that can be maintained over the long term without causing significant negative consequences such as high inflation, environmental damage, or resource depletion. It allows living standards to improve gradually while preserving opportunities for future generations.

In Australia, sustainable annual GDP growth is generally considered to be around 3% per year.

GDP per capita definition (including formula)

GDP per capita divides total GDP by the population, giving an average economic output per person. It is a much better indicator of average living standards than total GDP.

Formula: GDP per Capita = Total GDP ÷ Population

How does economic growth improve living standards

•      Higher incomes and wages

•      More employment opportunities

•      Better access to goods and services

Impacts of Economic Growth (positive and negative)

Positive impacts:

•      Reduced poverty and increased wealth

•      Higher employment levels

•      Greater business investment and innovation

Negative impacts:

•      Environmental degradation and pollution

•      Inequality may worsen if growth benefits are unevenly distributed

•      Inflationary pressure if growth is too rapid

Infation defintion

Inflation is the general and sustained increase in the prices of goods and services over time. Inflation is measured using the Consumer Price Index (CPI), which tracks the price of goods and services that an average household purchases.

Inflation is caused by…

Demand-Pull Inflation: This occurs when overall demand for goods and services increases faster than the economy's ability to produce them.

Cost-Push Inflation: This happens when the cost of producing goods and services rises. Factors like increased labor wages, expensive raw materials

The RBA's Target Range

In Australia, the Reserve Bank of Australia (RBA) is responsible for managing inflation. The RBA's official target is to keep inflation between 2% and 3% per year, on average, over the medium term. This range is considered:

•      High enough to avoid the dangers of deflation (falling prices)

•      Low enough to maintain price stability and confidence in the currency

Consistent with sustainable economic growth and full employment

Interpreting Inflation Graphs and Trends

When analysing an inflation graph, identify:

•      The current rate — is it above, below, or within the RBA's 2–3% target?

•      The direction — is inflation rising, falling, or steady?

•      The rate of change — is the change rapid or gradual?

•      Historical context — how does the current rate compare to past trends?

Inflation impacts on households

•      Cost of living rises (groceries, fuel, electricity, rent)

•      Fixed-income earners (e.g., retirees) are most affected

•      Savings lose value if interest rates don't keep pace with inflation
