Economics U4A2

Aggregate Supply

the total amount of goods and services that all firms in a country's economy plan to produce and sell at different price levels during a specific time period

Aggregate Supply Policy

government strategies designed to improve an economy's productive capacity, efficiency, and total output without increasing inflation

Short Run Aggregate Supply

total amount of goods and services that firms in an economy are willing and able to produce at different price levels over a short period of time, while resource prices (like worker wages) stay fixed

Long Run Aggregate Supply

• It represents the country's potential output at full employment

The use of AS policies to work with AD policies

• Education and training → improves labour productivity and the quality of the workforce.

• Infrastructure investment → reduces business costs and improves productivity.

• Deregulation / reducing red tape → lowers compliance costs and encourages businesses to invest and expand.

The operation of aggregate supply policies in improving supply-side conditions through their impact on

AS policies improve supply-side conditions by influencing the factors that determine the economy's ability to produce goods and services.

• Education and training → improves the quality of labour.

• Infrastructure investment → improves the quality and quantity of capital.

• Migration policies → can increase the quantity of labour.

The quantity and quality of the factors of production

AS policies can increase the quantity and/or quality of land, labour, capital and entrepreneurship, allowing the economy to produce more.

• Skilled migration → increases the quantity of skilled labour.

• Education and training → improves the quality of labour through greater skills.

The costs of production

AS policies can reduce the costs of producing goods and services, making Australian businesses more efficient and competitive.

• Lower business taxes → can reduce firms' costs and encourage investment.

• Improved infrastructure → reduces transport and distribution costs.

Productivity

AS policies can increase productivity, meaning more output can be produced from the same quantity of inputs.

• Training programs → improve worker skills and output per worker.

• Investment in technology → allows firms to produce more efficiently.

Australia's international competitiveness

AS policies can improve Australia's international competitiveness by reducing production costs and/or increasing productivity, making Australian exports more attractive relative to foreign goods.

• Productivity improvements → allow Australian firms to produce at lower unit costs.

• Infrastructure improvements → reduce costs associated with transporting Australian exports.

Productive capacity

AS policies can increase productive capacity, the maximum level of output an economy can sustainably produce using its available resources.

• Investment in capital → increases the economy's ability to produce goods and services.

• Increasing skilled labour → allows more output to be produced sustainably.

Aggregate supply

AS policies can increase aggregate supply (AS) by expanding the economy's ability to produce goods and services, shifting the LRAS curve to the right.

• Higher productivity → increases the amount firms can produce at each price level.

• Greater productive capacity → allows the economy to produce more without creating excessive inflation.

Infrastructure effect on AS, international competitiveness, achievement of DMEG goals and living standards

Australian Government investment in transport infrastructure, such as roads, railways and public transport.

• Aggregate supply: Better transport infrastructure reduces transport and distribution costs and improves productivity → increases productive capacity and aggregate supply.

• International competitiveness: Lower business and transport costs make Australian firms more cost competitive, making Australian exports more attractive overseas.

• DMEGs: Higher productivity and productive capacity promote economic growth; infrastructure projects create employment, supporting full employment. Greater AS can also reduce inflationary pressure, supporting price stability.

• Living standards: More employment, higher incomes and access to better infrastructure can increase material living standards; improved transport also contributes to non-material living standards by reducing travel times and congestion.

Skilled immigration policy

Skilled immigration policy — Permanent Migration Program

• Population: The Skilled stream increases Australia's working-age population, increasing the supply of labour.

• Productivity & participation: Skilled migrants bring skills and qualifications, increasing labour productivity and potentially increasing labour force participation.

• Productive capacity & AS: More workers and higher productivity increase productive capacity, shifting aggregate supply (AS) to the right.

• International competitiveness: A larger pool of skilled workers improves productivity and helps Australian businesses access skills they may otherwise lack, improving international competitiveness.

• DMEGs: Higher productive capacity supports economic growth; increased employment supports full employment; increased AS can reduce inflationary pressure.

• Living standards: Higher employment and incomes can increase material living standards, while skilled migration can also address skill shortages and improve access to goods and services.

Trade liberisation

Trade liberalisation is the reduction or removal of government restrictions on international trade, such as tariffs, quotas and other trade barriers, allowing greater competition and trade between Australia and other countries.

• International competitiveness

  • Short term: Greater competition pressures Australian firms to reduce costs and improve efficiency.

  • Long term: Increased productivity and specialisation improves Australia's international competitiveness.

• Allocation of resources

  • Short term: Resources move away from less competitive industries, potentially causing structural unemployment.

  • Long term: Resources are allocated towards industries where Australia has a comparative advantage, improving efficiency.

• Aggregate supply

  • Short term: Increased competition encourages firms to improve efficiency, causing a small increase in AS.

  • Long term: Greater productivity and efficiency increase productive capacity and shift LRAS right.

• DMEG goals

  • Short term: Structural unemployment can make full employment harder to achieve, although cheaper imports can reduce inflationary pressure.

  • Long term: Higher productivity and productive capacity support economic growth, while increased competition helps price stability.

• Living standards

  • Short term: Consumers benefit from lower prices and greater variety, increasing material living standards.

  • Long term: Higher productivity, economic growth and incomes can further improve material living standards.

Renewable energy subsidy

A government subsidy that reduces the cost of producing or investing in renewable energy, encouraging businesses and households to shift away from fossil fuels.

• Aggregate supply

  • Short term: Government subsidies reduce the cost of renewable energy production, potentially lowering production costs and increasing AS.

  • Long term: Increased investment in renewable energy can improve productivity and productive capacity, increasing LRAS.

• Intertemporal efficiency

  • Short term: Encourages resources to shift towards renewable energy and away from environmentally damaging energy sources.

  • Long term: Reduces environmental degradation and preserves natural resources for future generations, improving intertemporal efficiency.

• Living standards

  • Short term: Government spending on subsidies may have an opportunity cost, but cheaper/cleaner energy can benefit households and businesses.

  • Long term: A cleaner environment and more sustainable energy supply improve non-material living standards and help maintain living standards for future generations.
