Circular Flow of Income :: interactive calculator How to use the calculator: use the sliders to change the relative values for leakages, injections and consumption you can then determine the level of Aggregate Demand (AD), as well as whether the economy is in a blanked, contractionary, or expansionary phase. Why is this stuff important to know? Economies are in constant states of change. As economists, it's important that we can determine the level of cyclical economic activity. Understanding the changes in the level of AD in the economy helps decision-makers to make informed choices in regards to big decisions, such as: whether to invest in new capital for a business, or whether governments should increase or decrease expenditure. There are lots of other informed decisions that households, firms and government may make when they have a clear understanding on the cyclical nature of the economy. What are some other examples?

The Keynesian version of AD / AS model helps to visualise the relative position of the economy on the economic cycle, and to then infer output levels, price levels and employment levels. I find it really useful to keep an eye on the three zones of the AS curve: When an economy is really in a bad trough AD will intersect AS along the flat section - where even if AD was to then shift right (increase), output and employment levels can increase, but price level (inflation) stays pretty much the same. The curved section (intermediate zone) is where an increase in AD will result in increase output and employment, but some price level pressure starts to appear. This is where economies tend to function - maybe this could be the RBA 'sweet spot' of 2-3 % inflation. The steep (vertical) section of AS (classical zone) helps to visualise a situation where an economy is producing at full employment of resources. So output can't increase, and any further increase in AD will only create further inflationary pressure. Neoclassical Aggregate Demand and Supply :: interactive model How to use the interactive model use the sliders (or drag curves) to shift the global supply curve and tariff value or press the 'try a scenario' button Why is this stuff important to know? The neoclassical version of AD / AS model is helpful to distinguish short-run from long-run aggregate supply (SRAS and LRAS). Where the Keynesian AS curve fits the SRAS and LRAS into one curve, the distinction in this model helps to give a clearer picture of the LRAS as representing the maximum output of an economy at a point in time, regardless of price (aka the Production Possibilities curve!). Trade equilibrium will occur at intersect of SRAS and AD - this will determine quantity and price level. The relative position of trade in relation to LRAS can then determine the position of the economy on the economic cycle contracting or expanding (based on whether we are trading the total available supply or not). A shift to the right (increase in LRAS) represents structural economic growth - a sustained increase in the level of production output in the economy. This occurs when there is an improvement in the quality and/or quantity of resource inputs (factors of production). The Circular Flow of Income, Aggregate Demand and Government Intervention in Economic Cycles Keynesian Multiplier Calculator How to use the interactive model use the sliders to set levels of leakages - MPS, Tax rate, MPM then adjust slider to view the effects on GDP of an increase in Government Expenditure (injection) Why is this stuff important to know? The RBA has some good resources explaining how the multiplier works. Click here for the video At a high school level, you generally learn the simple multiplier formula that only takes into account MPS. The calculator here also considers effect of tax rates on multiplier outcomes, as well as the effects of imports. So it gives you a more rounded view of outcomes. And this stuff is kinda intuitive anyway - like it's probably not an ideal outcome for additional government expenditure to go completely towards purchase imported goods as it represents a leakage in circular flow, so it will have a limited multiplier effect. This calculator now gives you some mathematical rationale. Keynesian Cross Multiplier :: interactive model How to use the interactive model use the slider to adjust the MPC of the economy use slider to change level of Government Expenditure Why is this stuff important to know? This model represents a simple multiplier relationship of income and MPC. However it's important to remember that MPC isn't just income minus savings. MPC is the income available for consumption once all leakages (S + T + M) have been taken into account and removed from income. And then 'marginal' which means 'additional' - what is the proportion of additional expenditure when we get an extra dollar? The multiplier effect is visible as the increase in additional GDP - when governments put in $1 then we will see a greater than $1 increase in GDP Disclaimer: This is one of those economic models that I think some teachers teach and others don't seem to get too hung up on it. I've included it for completeness. If you can articulate the idea that each extra dollar of government expenditure has a proportionally larger effect on GDP, then you are probably okay. I think that my calculator above is probably a more useful tool to develop your understanding of multiplier effect.

Economics is a challenging and rewarding senior high school subject that will hone your skills in analysis, decision-making, and justifying your arguments. Economics occurs in real-time, and helps us to understand the intended and unintended consequences of decisions made by ourselves, and the people, firms and governments around us. Early economists were essentially the moral philosophers of their time, and I hope that through your study of economics you begin to question the world around you, and think of how you can contribute to a better future.

Unit 3 Topic 2: Global Economic Issues On this page: Tariffs: explainer video Tariffs on imports :: interactive model Trade tariffs :: interactive practice Quotas on imports :: interactive model Free Trade Agreements: useful websites Economic effects of Free Trade Agreements Assessment IA2: Help with data, research report structure, and report layout The three levels of economic data Subject matter for Unit 3 Topic 2: Global Economic Issues Tariffs - effects on trade and welfare :: interactive model How to use the interactive model: use the sliders (or drag curves) to shift the global supply curve and tariff value or press the 'try a scenario' button Why is this stuff important to know? When global trade occurs at the point of global allocative efficiency (equilibrium of D and S global), the most units are sold at the lowest price, and maximum consumer surplus is achieved. However domestic producer surplus is less than the levels attainable if only domestic trade takes place. Tariffs distort markets by imposing an additional cost to consumer who purchase imports. Some additional domestic producer trade may be realised, and the government can also grab some extra revenue. Ultimately however, there is a decrease in trade, and an increase in price. Source: Marginal Revolution University Tariffs - effects on trade and welfare :: interactive model How to use the interactive model: use the sliders (or drag curves) to shift the 'S global' curve and the 'S domestic + Quota' curve or press the 'try a scenario' button Why is this stuff important to know? Import quotas are a method used by governments to restrict the quantity of international goods entering domestic markets. In this interactive model, if an economy does not allow any entry of foreign goods, trade would occur at equilibrium point A ($120 and 3m units). However, if international trade were to occur without any import limits, trade equilibrium would shift to point X ($100 and 5m units). Import quotas give governments a method to have a controlled import of goods whilst still supporting domestic industries. The Australian car market benefitted from import quotas back in the day - for example, one car could be imported for every four made in Australia. The controlled method gives some additional choice for consumers at lower prices, whilst also providing a degree of protection for domestic producers. However, quotas are considered a market distortion and are not economically efficient. Free Trade Agreements: useful websites Australia's trade through time (interactive): https://www.dfat.gov.au/publications/minisite/tradethroughtimegovau/site/index.html About Free Trade Agreements: https://www.dfat.gov.au/trade/about-ftas/about-free-trade-agreements Australia's Free Trade Agreements: https://www.dfat.gov.au/trade/agreements/trade-agreements Source: Department of Foreign Affairs and Trade Economic effects of Free Trade Agreements When examining FTA's, it is important to distinguish between outcomes and economic effects. The outcomes listed on the DFAT website are the changes to trade barriers between nations as a result of the enacted FTA. Generally this is the removal of trade barriers such as tariffs, quotas etc. The bigger question to analyse is: what have been the economic effects as a result of nations enacting the FTA? So we can do some intertemporal analysis to determine the nature and size of trade before the FTA and after the introduction of the FTA. Let's workshop an analysis example of through examining the FTA between Australia and Indonesia: Australia entered an FTA with Indonesia in 2020. Prior to the FTA (2007 - 2019), total trade between the two nations grew at an annual average of about 5%. The dip around 2020 is likely a result of economic downturn of COVID pandemic, so let's start next analysis at 2021. After the implementation of the FTA, total trade between the two nations grew at an annual rate of 27% (2012 - 2024). It is important to recognise that correlation doesn't always equal causation, so it is important to deepen analysis by looking at different aspects of trade and relationships to determine the connections and economic effects. However, in this instance, the significant change in annual growth of trade can very likely be attributed to the improved market access (for both nations) introduced by the FTA. How could I deepen my analysis to evaluate the economic effects of the FTA? Step 1: Review the specific industry sectors where nations have sought to improve access to markets by the removal of trade barriers (eg. beef exports to Indonesia). Step 2: Develop your own analysis of the intertemporal changes within those industries (before and after FTA) to determine the relative effects of the FTA. Try to find examples where there is a positive effect, as well as examples where the FTA has had a limited (or negative) economic effect. Use your examination of the positive versus negative effects to create your 'on balance' evaluation. Assessment IA2: Research Report Research report structure Here is a video that provides a clear structure for a research report in economics. It can be difficult to know where to start, so the outline provided helps you to: Link your comprehension of economic theory to an economic issue in society. Understand how to analyse the issues from the perspectives of various stakeholders. Develop a logical and persuasive evaluation and balanced judgement. Internal Assessment (IA2) for this topic is a REPORT. Here is a video giving some guidance on report structure and layout, using MS Word. Remember: 4 of the 25 marks for this IA relates to "creating a response", so spend some time getting your report up to an excellent professional standard, and grab four easy marks. Useful data tools for your research. Here is a video explaining how to use the data visualisation tools at the International Monetary Fund website. This website has the most comprehensive range of economic data sets available. Go to https://www.imf.org/en/Data THE THREE LEVELS OF ECONOMIC DATA A big challenge in writing an economics research report is figuring out how to connect the data to demonstrate elements such as cause and effect relationships - how do we create a path of analysis from the microeconomic issues through to macroeconomic outcomes? So let's have a look at how we can create a three level system to deepen our analysis. LEVEL 1 DATA Data relating to a stakeholder or individual sector of the economy (eg.firms and industry sectors, consumers or government) Examples: data on industry trade with foreign customers foreign investment activity into an industry sector (eg. mining investment) LEVEL 2 DATA Data relating to an overall (aggregate) aspect of trade or investment Examples: total export or import trade values or volumes total foreign investment Balance of Trade Currency valuations LEVEL 3 DATA The macroeconomic indicators: Gross Domestic Product Inflation Employment Balance of Payments Applying the three levels of economic data :: Australia / China trade example In 2021, China enacted a range of trade protection on imports from Australia. Most of these barriers were removed in 2023. The three level model helps us to analyse and evaluate outcomes during this period of export trade constraints. LEVEL 1 Australia coal exports to China LEVEL 2 Australia- China bilateral balance of trade LEVEL 3 Australia Current Account Creating connections between data and economic information presents a significantly more complete picture: At level 1 , the negative effect of China trade protection on Australia's coal exports is clearly evident. This then flows through to level 2 , where a downturn in bilateral trade balance is evident in 2022. At level 3 , the effect is also evident in Net Goods and Services (top line) and Current Account Balance (red line). I think you'll agree that this method provides some significant insight into the issue, and yields a deeper analysis than just focussing on a dataset in isolation. Some final ideas: Remember: Correlation doesn't always equal causation , so make sure you do further research to determine cause-and-effect. The Analysis criteria in the marking guide requires "discerning meaning drawn from patterns and trends ..." as well as "... explanation of economic relationships ...". I reckon that this three level model will give you some targets to achieve "discernment". Subject matter Topic 2: Global economic issues In Topic 2, students study three major factors affecting Australia’s trade relationships with the rest of the world. Firstly, the factors that have contributed to globalisation are explored from Australia’s viewpoint. Secondly, economic ideas and models are used to examine the impacts of different barriers to trade, and the economic tensions they create. Finally, the impacts of international trading agreements are considered. Describe key concepts using economic terminology, including methods of trade protection, economic integration, economic union, globalisation and trade liberalisation. Explain, analyse and evaluate the factors that have contributed to the growth of multi-company and multinational supply chain integration, e.g. the location of natural factor endowments; digital and other innovation; infrastructure (including logistics); and government incentives factors that have contributed to globalisation and current international trade patterns, including technology; multi-national corporations; regional trading blocs; and deregulation of financial capital markets and of non-government institutions, e.g. the World Trade Organization, International Monetary Fund and World Bank Explain the methods of protection employed by nations, and construct supply and demand diagrams to demonstrate the effect of methods of trade protection, including tariffs and non-tariff barriers (e.g. subsidies, quotas and bureaucratic requirements). Analyse and evaluate the economic arguments for and against protectionism and trade liberalisation responses from different viewpoints using economic criteria (e.g. economic efficiency, economic growth, living standards or resource allocation) to make a decision about the past, present or future regarding the relative merits of trade policy alternatives. Explain bilateral, regional and multilateral trade agreements that involve Australia the contemporary role of ‘free trade’ agreements and their impact on Australia’s international trade, including trade creation and trade diversion. Analyse and evaluate the economic outcomes of international trading bloc agreements (e.g. Australia–New Zealand Closer Economic Relations Trade Agreement (CER), European Union (EU), North American Free Trade Agreement (NAFTA), ASEAN–Australia–New Zealand Free Trade Agreement (AANZFTA)) on Australian economic growth, and decide on the net benefits using economic criteria, e.g. economic efficiency, economic growth, living standards or resource allocation. Create responses that communicate economic meaning using data, information, graphs and diagrams in paragraphs and extended responses to suit the intended purpose.

Consequently, increased demand for AUD to pay for these commodities leads to currency appreciation. 2010–2013: Parity with the USD: In October 2010, the AUD reached parity (1:1) with the USD for the first time since it became a floating currency (1983). It peaked above US$1.10 in July 2011. 2014–2020: Post-Boom Normalisation: Following the end of the mining investment boom and falling terms of trade, the AUD depreciated from its 2013 highs. It hit a low point during the initial COVID-19 pandemic market stress in March 2020. 2021–2026: Consolidation and Volatility: The AUD has generally hovered lower, influenced by interest rate differentials between the RBA and the US Fed. The Australian cash rate has been lower than US cash rate, thus influencing flow of financial investment to US. In turn, this increases demand for USD, and consequently reduces demand to AUD - so AUD value falls relative to USD. Also, China's economic performance is below historic demand, which reduces commodity exports . As of early 2026, the AUD is considered undervalued by some, acting as a buffer (automatic stabiliser) for the economy - eg. maintaining export volumes / output as export goods are relatively cheaper for overseas buyers. Primary Drivers of the AUD (Since 1999) Terms of Trade (Commodity Prices): The most significant driver. High commodity prices (mining boom) drive appreciation, while declining terms of trade (post-2013) drive depreciation. China Exposure: Because a large portion of Australian exports go to China, the AUD is highly sensitive to China's economic health and manufacturing sector. Interest Rate Differentials: The gap between RBA rates and other major central banks (especially the Fed) influences capital flows. Higher relative rates in Australia tend to support the AUD. Global Risk Sentiment: As a "risk-on" currency, the AUD often appreciates during times of global economic optimism and depreciates during crises (flight to quality). Structural Changes to the Australian economy Internationalisation: The AUD has become the 6th most traded currency globally, with the AUD/USD pair being the 4th most traded. Floating Exchange Rate: The RBA has maintained a free float, which has allowed the currency to act as a "shock absorber" for the economy, adjusting to commodity price shocks. Inflation & Purchasing Power: $100 in 1999 had the same purchasing power as approximately $209.94 in 2026, reflecting a 109.94% cumulative price increase over that period. Australia Composition of Trade What is "composition of trade"? Composition of trade refers to the mix of goods and services that a nation exports and imports. How is it represented in data and graphs? The graphs generally reflect the data as the percentage (%) that a particular industry constitutes as a total of export or import trade. You will most often see time series graphs, which help us to interpret changes over time ("temporal change" if you want to use some fancy words). Sometimes you might see a pie graph which will give you the information for a point in time. It is important to remember that this shows the industry share of exports and imports. It doesn't show the total export volumes (which are likely rise across time aross out industries). Why is understanding the composition of trade important? Interpreting temporal change in composition of trade helps us to identify structural changes in the types of industries in global economies. We can spot emerging industries, as well as industries in decline. We can also identify changes in demand for different types of exports and imports, as well as changes in supply. So then we can identify the industries where a nation may have a comparative and / or competitive advantage. Analysis of Australia's export composition of trade You can easily identify some big changes in Australia's composition of exports: The growth of resources exports - now constituting over 60% of Australia's total exports. The decline in agricultural exports as a share of total exports. What other changes can you spot? eg. manufacturing? REMEMBER: the graph shows share of exports - not volume of exports, so whilst an industry may have a smaller share, it still may be exporting more goods and services at historically high levels! Source: Reserve Bank of Australia Explain the effects of changes to Australia's composition of trade The second marking criteria under Analysis is 'discerning explanation of economic relationships', so let's try and get 'discerning': What are the theoretical positive effects of the changes that you have identified in the data? What are the theoretical negative effects of the changes? And then what data could help you to expand your response and provide a deep discussion and justification of outcomes? Example: Australia has high share of total exports in resources. Most likely flowing to China as the major customer. Positive: Likely increase in productive capacity and output, utilising our abundance of 'land' factors of production, which creates employment and increases national income in high productivity industries. Negative: Heavy reliance on a particular export industry - what happens to our total export volume when demand for resource exports decreases? How does that affect GDP? (Hint: have a look at the decline in Australia's GDP around 2016 when the Chinese economy experienced contraction (or 2020 during the Covid pandemic). What other positives and negatives can you think of, and what additional economic information would you need to access to help to expand your response and provide deep discussion of outcomes? Analysis of Australia's import composition of trade The import composition of trade doesn't indicate the same level of significant changes as the export composition of trade. We can note that consumer goods are on the rise (as a share of total imports) as well as transport equipment. This makes sense. The decline in manufacturing in Australia means that we rely more heavily on imports of final goods (including motor vehicles) than we did back in the 1960's. Another interesting aspect in the graph (related to the decline in Australian manufacturing) is the decrease in Industrial supplies - the materials that are used in manufacturing processes. Source: Reserve Bank of Australia Now over to you: Use the method of analysis demonstrated above for export composition of trade and make the analysis for the import data. Identify trends, patterns, similarities and differences Make sure that you are clear on the big changes and compare and contrast to the small changes ('discerning') Quantify and calculate (eg % change, range, $ values, rate of change, volatility etc) Explain the positive and negative effects (both theoretical effects, and any effects reflected in data) Terms of Trade Australia OECD definition: Terms of trade reflect the relative price between a country’s exports and imports, and are measured as the ratio of the export price index to the import price index. Terms of trade indicate whether a country can purchase more or fewer imports for the same amount of exports. An increase in export prices relative to import prices signals an improvement in terms of trade. The indicator is presented as an index, with 2020 as the base year. Quick analysis: Australia's terms of trade have improved significantly over the last 25 years primarily due to a sustained boom in commodity export prices (iron ore, coal, LNG), driven by rapid industrialisation in China and emerging Asian economies. This was supported by increased export volumes, competitive depreciation of the Australian dollar at times, and falling import prices for technology. Key factors driving the improvement include: The Mining Boom (Structural change) Export Volume & Price Growth Declining Import Prices Diversification & Trade Agreements Service Export Growth Deepen your understanding: Click here for the Australia and the Global Economy – The Terms of Trade Boom Explainer from the Reserve Bank of Australia Australia Net Exports / Balance of Trade (BoGS) How to analyse the data 1. Calculation and economic theory Before you begin analysing any data, make sure that your understanding of the relevant economic theory is solid. Net Export data is the same as Balance of Trade and Balance of Goods Sold / Services (as we refer to it in the the Balance of Payments). The formula is value of exports minus value of imports. In other words X-M. See the link here back to leakages and injections in the Circular flow model! Net exports is a component of the Aggregate Demand formula, where AD=C+I+G+(X-M). 2. Review the information in the graph Make sure you are clear on: title, explanatory notes, the units of measure. Check if price values are abbreviated on the y-axis. Link your formula to the data to build some understanding. 3. Interpret the data Where net export value is less than zero, Australia has imported more goods and services than it has exported. So there is a net loss of income out of Australia. Where net export value is greater than zero, Australia is exporting more goods and services than it is importing, So we see a net inflow of income into Australia. 4. Make meaning of the data Use your analysis 'toolkit' (eg. cause and effect, compare and contrast etc) to deepen your interpretation. My take is that historically (up until 2008/9) Australia has been a net importer of goods and services. Effect is that we are sending our income overseas, so leakages are greater than injections, and therefore, the Net Export position is having a contractionary effect on economic activity. Then in 2009 we see a significant change to a positive net export position around the time of the 'mining boom' (big increase in commodity exports to China. There were a few contributing factors: Higher value AUD (higher price for the same quantity of the export) - check the currency data above Higher commodity prices (high levels of demand led to higher per-unit prices) - check the terms of trade data above Increased volume of sales In 2022 we see the most significant change in Net Exports in the data set. So what caused the changes? Here are some likely reasons: Exports increased whilst Imports remained the same, or Exports stayed the same and Imports decreased, or Exports increased and Imports decreased. Also, how could we interpret the Terms of Trade data on relative prices to help us determine causes ? And what was the AUD value at the time? Now its up to you to find the real world information to determine the reasons for this significant change. 5. Consider the effects on stakeholders and implications for the economy In step four you considered the economic events that caused the changes. Your understanding of economic theory can help you to extrapolate effects on stakeholders (households, firms and government). You can also dive into further data find effects (eg. did export-oriented firms receive increased income during the positive Net Export periods). Give this method a try with other data and let me know if it works! Foreign Investment There are two main ways in which foreign residents or companies can invest funds in the Australian economy: Portfolio investment (PI) refers to the purchase of securities (such as stocks or bonds) or equity and debt transactions that do not offer the investor any control over the operation of the enterprise. Common examples include the purchase of property (equity), shares in Australian companies (equity) or government bonds (debt) by foreign superannuation or pension funds. Foreign direct investment (FDI) is when an individual or entity from outside Australia establishes a new business or acquires 10 per cent or more of an Australian enterprise, and so has some control over its operations. Common examples include the establishment of Australian branches of multinational companies or joint ventures between Australian and foreign companies. (from: https://www.dfat.gov.au/trade/investment/about-foreign-investment) Graph 1: Graph 2: How to analyse the data 1. Calculation and economic theory Before you begin analysing any data, make sure that your understanding of the relevant economic theory and key terminology is solid. Some ideas to review: What is the purpose of FDI into Australian economy? What do we call the financial returns to on FDI to international investors? (Hint: think back to your sources of income from factors of production in Unit 1) What are the two ways in which investors acquire a financial return on PI - Equity? What is the financial return on government bonds and other debt called? Net International Investment Position = Australian Investment abroad / outflows (assets) minus Foreign Investment in Australia / inflows (li abilities) 2. Review the information in the graph Make sure you are clear on: title, explanatory notes, the units of measure. Check if price values are abbreviated on the y-axis. Link your formula to the data to build some understanding. 3. Interpret the data Using graph 1 (above at left), we can determine the following investment outcomes in 2024: Australia is a net liability holder (negative value) in Direct Investment - higher investment inflows into Australia than Australia invests abroad (outflows). Australia is a net asset holder (positive value) In Portfolio Investment (Equity) - Australians invest into overseas share markets at a higher value than international investment into Australian share market. Outflows are greater than inflows. International markets have significantly higher investment in Australian debt markets than we have in international debt markets. Outflows are less than inflows. Graph 2 shows the trends over time of international investment position. We can see that international investment into Australia has always been higher than Australian investment abroad. Australia’s International Investment Position (IIP) was a liability of $653.2b at 31 December 2024, a decline of $165.5b from the end of 2023. Net Investment data from the World Bank can help us to deepen our analysis: The trend to negative net FDI values means that there are increasing levels of International FDI into Australia relative the level of Australian FDI investment abroad The trend to positive net PI values means there are increasing levels of Australian PI investment abroad, relative to the level of PI investment coming into Australia from overseas 4. Make meaning of the data Use your analysis 'toolkit' (eg. cause and effect, compare and contrast etc) to deepen your interpretation. From the data available above, my take is that generally Australia has experienced net inflows of FDI - more investment dollars from Australia being invested overseas than foreign stakeholders are investing in Australia. In contrast to the FDI liability position, the PI position displays a trend towards positive values, signifying greater net outflows of PI. So we get FDI into Australia to build our productive capacity so firms can increase output and deliver profit through direct ownership in firms (which has low liquidity / difficult transfer of ownership). And Australia invests overseas in equities such as shares (high liquidity / easy transfer of ownership) that will deliver either capital growth in value, or dividend returns, or both. 5. Consider the effects on stakeholders and implications for the economy In step four you considered the economic events that caused the changes. Your understanding of economic theory can help you to extrapolate effects on stakeholders (households, firms and government). eg. these investments will yield income return for investors - what will be the net flows of income from, say, a negative FDI position? eg. Australian portfolio investment abroad is very strong - where did this money come from and what are the longer-term effects? Some ideas to help you along the last two steps: Key Trends in Australia’s Net Investment Position Resources Boom (2002–2007): The mining boom spurred massive foreign capital investment into Australia to increase the productive output of the mining sector. Shift to Net Equity Assets (2013–Present): A major structural change occurred around 2013, where Australia shifted from being a net foreign equity liability position to a net foreign equity asset position. This means Australians now own more equity in foreign companies than other nations own in Australian companies. This change has been largely driven by the growth of the Australian superannuation sector, which totals AUD$4.3 trillion (as of October 2025). Key Drivers of Change Superannuation Growth: The mandatory superannuation system has increased national savings, reducing the need for foreign funding for domestic investment, as well as providing cash for investment in other overseas firms and government Valuation Effects: Strong performance of foreign equity holdings (eg. shares in foreign companies) by Australian funds has boosted outward investment values. Currency Value: a structural decline in value of AUD from 2012 onwards increases the value of overseas investments held by Australians. Australia's Balance of Payments Balance of Payments (BoP) account is a statistical record of the money value of all financial transactions between Australia and the rest of the world. BOP is important because : BOP summarises economic conditions in a nation BOP helps to evaluate a country’s solvency Summarises nature, size, composition and direction of a country’s international trade It clarifies the foreign exchange position of a country e.g. high Aust exports = high demand for AUD from other nations = increase in relative value of AUD It informs the trade, industrial and economic policies of the Government: If balance of payments is favourable, the Government will take liberal view of imports, otherwise different types of restrictions (tariff and non-tariff measures) will be imposed as corrective measures.

Why is this stuff important to know? Read below the interactive for more information on the measurements used, and possible government policy responses. Check out inequality data from all around the world :: click here to access the database Lorenz Curve, Gini Coefficient and Palma Ratio These three tools measure income inequality within an economy, providing governments and economists with evidence to evaluate distributional outcomes and design policy responses. What they are: The Lorenz Curve plots the cumulative share of income received against the cumulative share of the population, ranked from poorest to richest. A perfectly equal society produces a 45-degree diagonal line. The further the Lorenz Curve bows away from this line, the greater the inequality. The Gini Coefficient quantifies this inequality by measuring the area between the Lorenz Curve and the line of perfect equality, expressed as a value between 0 (perfect equality) and 1 (perfect inequality). Higher values indicate greater income concentration among top earners. The Palma Ratio compares the income share of the richest 10% against the poorest 40%, reflecting evidence that middle-income groups tend to receive a relatively stable share across countries, making top-to-bottom comparisons more meaningful. Why measuring inequality matters: Persistent inequality reduces social mobility, undermines economic participation, increases poverty, and weakens social cohesion. High inequality correlates with poorer health outcomes, higher crime rates, and reduced intergenerational opportunity. Policy responses: Progressive taxation — higher income earners paying proportionally more Transfer payments — welfare, pensions, and unemployment benefits redistributing income Investment in public services — universal healthcare, education, and housing reducing effective inequality Minimum wage legislation — lifting incomes at the bottom of the distribution Real-world examples: Scandinavian countries recording Gini coefficients below 0.30, reflecting strong redistribution South Africa recording one of the world's highest Gini coefficients above 0.60 Australia's Gini sitting around 0.34, moderate by developed-nation standards The Palma Ratio highlighting extreme concentration of income in nations like Brazil and Chile Subject matter Topic 2: Inequality Describe key concepts using economic terminology, including absolute and relative poverty, egalitarian society, income, transfer payments, wealth, and the welfare state. Describe a range of measures and indicators of inequality, e.g. the Lorenz curve, Gini coefficient, Henderson poverty lines, household income, mean and medium income, and equivalence scales. Explain the causes of inequality of income and wealth in Australia (e.g. educational attainment, employment status, gender, age, occupation, ethnic background, uneven distribution of factors of production, and family structure) and other factors that impact particular groups in society, e.g. Australian Aboriginal peoples and Torres Strait Islander peoples, migrants, and people living with disabilities. Select data and information from sources that offer evidence of the consequences of inequality in Australia and examine these sources to appreciate their underlying assumptions and perspectives.

Unit 2 Topic 1: Markets and Efficiency On this page: Negative Externalities of Production :: interactive model Positive Externalities of Production :: interactive model Negative Externalities of Consumption :: interactive model Positive Externalities of Consumption :: interactive model Price Floor :: interactive model Price Ceiling :: interactive model Subject matter for Unit 2 Topic 1: Markets and Efficiency Negative Externalities of Production A negative externality of production occurs when a firm's production process imposes costs on third parties who are neither buyers nor sellers in the market. The firm's private costs (MPC) understate the true social cost (MSC), causing the market to overproduce beyond the socially optimal level (Q*). How it occurs: Firms maximise profit by producing where MPC equals demand, ignoring spillover costs imposed on others — pollution, noise, health damage, or environmental degradation. This overproduction creates a deadweight welfare loss, representing value permanently destroyed. Why it matters: Unregulated markets systematically overproduce harmful goods. Society bears costs the producer never pays — healthcare burdens, environmental cleanup, reduced quality of life, and intergenerational damage. Without intervention, this market failure persists indefinitely. Solutions: Pigouvian taxes — taxing producers equal to the MEC per unit, shifting MPC up to MSC Regulations — emission standards, production limits, technology mandates Tradeable permits — cap-and-trade schemes setting pollution ceilings Subsidies for cleaner alternatives — incentivising firms to adopt greener methods Real-world examples: Coal power stations emitting carbon dioxide and particulates Factories releasing chemical waste into waterways Logging operations destroying biodiversity and watersheds Livestock farming generating methane contributing to climate change Positive Externalities of Production A positive externality of production occurs when a firm's production process generates benefits for third parties who are neither buyers nor sellers in the market. The firm's private costs (MPC) overstate the true social cost (MSC), causing the market to underproduce below the socially optimal level (Q*). How it occurs: Firms only consider their own private costs and revenues when making production decisions, ignoring spillover benefits flowing to others — skilled workers, knowledge diffusion, improved infrastructure, or community wellbeing. This underproduction creates a deadweight welfare loss, representing unrealised social value. Why it matters: Unregulated markets systematically underprovide goods with positive spillovers. Society misses out on benefits the producer never captures — technological advancement, workforce development, economic growth, and improved living standards. Without intervention, valuable productive activity remains permanently suppressed. Solutions: Production subsidies — reducing the firm's costs, shifting MPC down to MSC Direct government provision — publicly funding industries with large spillover benefits Research and development grants — encouraging innovation and knowledge creation Tax concessions — reducing the tax burden on high-spillover industries Real-world examples: Pharmaceutical companies developing vaccines that protect entire communities Technology firms whose R&D generates knowledge spillovers across industries Forestry companies replanting trees, improving air quality and biodiversity Construction firms building infrastructure that benefits surrounding businesses and residents Negative Externalities of Consumption A negative externality of consumption occurs when an individual's consumption of a good imposes costs on third parties who are neither buyers nor sellers in the market. The consumer's private benefit (MPB) overstates the true social benefit (MSB), causing the market to overconsume beyond the socially optimal level (Q*). How it occurs: Consumers maximise personal satisfaction by consuming where MPB equals MPC, ignoring spillover costs imposed on others — passive smoking, congestion, noise pollution, or social harm. This overconsumption creates a deadweight welfare loss, representing value permanently destroyed through excessive consumption. Why it matters: Unregulated markets systematically overconsume harmful goods. Society bears costs the consumer never pays — healthcare burdens, reduced amenity, social dysfunction, and long-term community damage. Without intervention, this market failure compounds over time, disproportionately affecting vulnerable populations who cannot avoid the spillover costs. Solutions: Pigouvian taxes — taxing consumers equal to the MEC per unit, shifting MPB down to MSB Regulations and bans — restricting consumption in public spaces or outright prohibition Education campaigns — informing consumers of true social costs to shift preferences Age restrictions and licensing — limiting access to harmful goods Real-world examples: Cigarette smoking imposing healthcare costs and passive smoking risks on non-smokers Excessive private vehicle use generating congestion, emissions, and road wear Alcohol consumption contributing to violence, healthcare costs, and family breakdown Plastic packaging creating long-term pollution and environmental degradation Positive Externalities of Consumption A positive externality of consumption occurs when an individual's consumption of a good generates benefits for third parties who are neither buyers nor sellers in the market. The consumer's private benefit (MPB) understates the true social benefit (MSB), causing the market to underconsume below the socially optimal level (Q*). How it occurs: Consumers only consider their own private benefits when making consumption decisions, ignoring spillover benefits flowing to others — herd immunity, reduced crime, increased productivity, or community cohesion. This underconsumption creates a deadweight welfare loss, representing unrealised social value that the market fails to capture. Why it matters: Unregulated markets systematically underprovide goods with positive consumption spillovers. Society misses out on benefits the consumer never considers — improved public health, reduced inequality, stronger communities, and long-term economic growth. Without intervention, underconsumption of socially valuable goods persists indefinitely, widening gaps between private and social outcomes. Solutions: Subsidies and vouchers — reducing the consumer's price, shifting MPB up to MSB Direct government provision — publicly funding education, healthcare, and vaccinations Awareness campaigns — highlighting social benefits to encourage greater consumption Compulsory consumption — mandating uptake of high-spillover goods such as education Real-world examples: Vaccination programs creating herd immunity that protects entire communities Education raising workforce productivity, reducing crime, and strengthening civic participation Public transport reducing congestion, emissions, and infrastructure wear for all road users Home insulation reducing household energy consumption and lowering neighbourhood carbon emissions Price Floors A price floor is a government-imposed minimum price set above the market equilibrium price (Pe). Because the floor price (Pf) exceeds equilibrium, quantity supplied (Qs) exceeds quantity demanded (Qd), creating a persistent market surplus and deadweight welfare loss. How it occurs: When governments intervene to keep prices artificially high, producers are incentivised to supply more while consumers demand less. The gap between Qs and Qd represents unsold surplus — goods produced but unable to find buyers at the mandated price. A non-binding floor set below equilibrium has no market effect. Why it matters: Price floors distort market signals, misallocate resources, and reduce overall economic efficiency. Deadweight welfare loss represents mutually beneficial trades permanently prevented. Surpluses create storage, disposal, and opportunity cost burdens. Workers or producers may benefit short-term while consumers and overall welfare suffer. Solutions: Government purchasing — buying surplus production to support the floor price Export incentives — redirecting surplus production to international markets Production quotas — limiting supply to reduce surplus while maintaining price Gradual deregulation — phasing out floors to restore market efficiency Real-world examples: Minimum wage legislation setting a floor on labour markets Agricultural price supports guaranteeing farmers minimum prices for wheat, dairy, and sugar European Union Common Agricultural Policy maintaining artificially high farm gate prices Minimum alcohol pricing policies setting floors on per-unit alcohol sales Price Ceilings A price ceiling is a government-imposed maximum price set below the market equilibrium price (Pe). Because the ceiling price (Pc) is below equilibrium, quantity demanded (Qd) exceeds quantity supplied (Qs), creating a persistent market shortage and deadweight welfare loss. How it occurs: When governments intervene to keep prices artificially low, consumers are incentivised to demand more while producers supply less. The gap between Qd and Qs represents unsatisfied demand — consumers willing to pay but unable to find goods at the mandated price. A non-binding ceiling set above equilibrium has no market effect. Why it matters: Price ceilings distort market signals, discourage production, and reduce overall economic efficiency. Deadweight welfare loss represents mutually beneficial trades permanently prevented. Shortages create queuing, black markets, reduced quality, and non-price rationing. While intended to protect consumers, ceilings often harm the very people they aim to help by reducing supply over time. Solutions: Targeted welfare payments — supporting low-income consumers directly without distorting prices Supply-side subsidies — encouraging greater production to reduce equilibrium price naturally Gradual deregulation — phasing out ceilings to restore market efficiency Price decontrol with safety nets — removing ceilings while protecting vulnerable households Real-world examples: Rent controls limiting maximum rents in cities such as New York, Berlin, and San Francisco Petrol price caps imposed during oil crises to protect consumers from price spikes Utility price regulation capping electricity and gas prices for household consumers Interest rate ceilings on loans limiting the maximum rate lenders can charge borrowers Subject matter Topic 1: Markets and Efficiency In Topic 1, students understand that markets can fail when the price mechanism results in a sub- optimal allocation of resources. They examine market failure and explore traditional and innovative measures and strategies using economic criteria, for example socially optimal and/or efficient outcomes. This topic analyses how markets may not always work efficiently and effectively, and the different choices and opportunities that exist when this phenomenon occurs. Describe key concepts using economic terminology, including allocative efficiency, productive efficiency, dynamic efficiency, externalities, incentives, market failure, monopolistic competition, perfect competition, oligopoly, monopoly, goods (public, private, merit and demerit), and market signals. Describe the - meaning of allocative, productive and dynamic efficiency as these relate to the optimal operation of markets - economic forces that limit perfect competition and foster an oligopoly market structure in many Australian industries. Compare optimal versus socially desirable outcomes. Analyse the differences between complete market failure (missing markets) and partial market failure. Explain the causes and effects of market failure, including - how the excesses of boom and bust cycles in economic growth may result in suboptimal and socially undesirable outcomes - the concepts of positive and negative externalities of production and consumption with a diagrammatic representation of the welfare loss/benefit associated with them - the difference between public goods (e.g. fresh air, national security, street lighting) and private goods, why markets might not adequately provide public goods and the concept of the free rider problem - ways in which the immobility of factors of production might lead to the misallocation of resources. Explain the causes and effects of market failure in at least one of the following situations - how market power may create a loss of market efficiencies - the ‘tragedy of the commons’ as it relates to common resources and the problem of ill- defined property rights, e.g. oceans and the atmosphere - how the lack of common ownership and the problems associated with global coordination limit government options when modifying markets, e.g. global warming and space junk in the outer atmosphere - asymmetric (imperfect) information that could lead to a misallocation of resources, e.g. adverse selection such as in the market for used cars (lemons), and moral hazard - how the features and characteristics of the extension of property rights may resolve economic inefficiencies associated with common resources, e.g. economic exclusion zones and economic zones in national parks. Explain different methods of market modification required to correct market failure, including direct and indirect taxation (e.g. Pigouvian taxes), subsidies, price floors/ceilings. Examples of different methods are suasion, tradable permits or direct state provision and regulation. Select data and information to analyse and evaluate - strategies to mitigate market failure, to improve equity or efficiency within the economy, including the creation of opportunities for innovation - the tension between costs to individuals and society of market failure - intended and unintended consequences of possible mitigation methods. Create responses that communicate economic meaning using data, information, graphs and diagrams in paragraphs and extended responses to suit the intended purpose.

Unit 1 Topic 1: The Basic Economic Problem On this page: Topic overview video What is economics? The division and specialisation of labour Why study economics? Factors of production Economic activity versus economic growth (and the factors of production) Production Possibilities Curve :: interactive model The Production Possibilities Curve (economic activity and economic growth) Production Possibilities Curve (interactive practice) Video Overview of Unit 1 Topic 1: linking the content to the syllabus PART 1: WHAT IS ECONOMICS? Syllabus: Describe the basic economic problem of relative scarcity and the need for decision-making by individuals, businesses and governments at local, state, national and international levels. Economics is the study of how humans make decisions in the face of scarcity. These can be individual decisions, family decisions, business decisions or societal decisions. If you look around carefully, you will see that scarcity is a fact of life. Scarcity  means that human wants for goods, services and resources exceed what is available. Resources, such as labour, tools, land, and raw materials are necessary to produce the goods and services we want but they exist in limited supply. Of course, the ultimate scarce resource is time - everyone, rich or poor, has just 24 hours in the day to try to acquire the goods they want. At any point in time, there is only a finite amount of resources available. Think about it this way: in November 2021, the labour force in Australia contained over 13,177,300 workers, according to the Australian Bureau of Statistics (ABS)[1]. Similarly, the total area of the Australia is 7,692,020 square kilometres[2]. These are large numbers for such crucial resources, however, they are limited. Because these resources are limited, so are the numbers of goods and services we produce with them. Let’s delve into the concept of scarcity a little deeper, because it is crucial to understanding economics. The Problem of Scarcity Think about all the things you consume: food, shelter, clothing, transportation, healthcare, and entertainment. How do you acquire those items? You do not produce them yourself. You buy them. How do you afford the things you buy? You work for pay. Or if you do not, someone else does on your behalf. Yet most of us never have enough to buy all the things we want. This is because of scarcity. So how do we solve it? Every society, at every level, must make choices about how to use its resources. Families must decide whether to spend their money on a new car or a fancy vacation. Towns must choose whether to put more of the budget into police and fire protection or into the school system. Nations must decide whether to devote more funds to national defence or to protecting the environment. In most cases, there just isn’t enough money in the budget to do everything. So why do we not each just produce all of the things we consume? The simple answer is most of us do not know how, but that is not the main reason. When you study economics, you will discover that the obvious choice is not always the right answer—or at least the complete answer. Studying economics teaches you to think in a different of way. Think back to pioneer days, when individuals knew how to do so much more than we do today, from building their homes, to growing their crops, to hunting for food, to repairing their equipment. Most of us do not know how to do all—or any—of those things. It is not because we could not learn. Rather, we do not have to. The reason why is something called the division and specialization of labour, a production innovation first put forth by Adam Smith,  in his book, The Wealth of Nations. PART 2: The Division of and Specialisation of Labour The formal study of economics began when Adam Smith (1723–1790) published his famous book  The Wealth of Nations in 1776. Many authors had written on economics in the centuries before Smith, but he was the first to address the subject in a comprehensive way. In the first chapter, Smith introduces the  division of labour, which means that the way a good or service is produced is divided into a number of tasks that are performed by different workers, instead of all the tasks being done by the same person. To illustrate the division of labour, Smith counted how many tasks went into making a pin: drawing out a piece of wire, cutting it to the right length, straightening it, putting a head on one end and a point on the other, and packaging pins for sale, to name just a few. Smith counted 18 distinct tasks that were often done by different people—all for a pin, believe it or not! Modern businesses divide tasks as well. Even a relatively simple business like a restaurant divides up the task of serving meals into a range of jobs like top chef, sous chefs, less-skilled kitchen help, servers to wait on the tables, a greeter at the door, janitors to clean up, and a business manager to handle paychecks and bills—not to mention the economic connections a restaurant has with suppliers of food, furniture, kitchen equipment, and the building where it is located. A complex business like a large manufacturing factory, or a hospital can have hundreds of job classifications. Why the Division of Labour Increases Production When the tasks involved with producing a good or service are divided and subdivided, workers and businesses can produce a greater quantity of output. In his observations of pin factories, Smith observed that one worker alone might make 20 pins in a day, but that a small business of 10 workers (some of whom would need to do two or three of the 18 tasks involved with pin-making), could make 48,000 pins in a day. How can a group of workers, each specializing in certain tasks, produce so much more than the same number of workers who try to produce the entire good or service by themselves? Smith offered three reasons. First, specialisation in a particular small job allows workers to focus on the parts of the production process where they have an advantage. People have different skills, talents, and interests, so they will be better at some jobs than at others. The particular advantages may be based on educational choices, which are in turn shaped by interests and talents. Only those with medical degrees qualify to become doctors, for instance. For some goods, specialization will be affected by geography and climate—it is easier to be a wheat farmer in rural Western Australia than in Cairns, but easier to run a tourist hotel in Cairns than in the Western Australian wheatbelt. Whatever the reason, if people specialise in the production of what they do best, they will be more productive than if they produce a combination of things, some of which they are good at and some of which they are not. Second, workers who specialise in certain tasks often learn to produce more quickly and with higher quality. This pattern holds true for many workers, including assembly line laborers who build cars, stylists who cut hair, and doctors who perform heart surgery. In fact, specialised workers often know their jobs well enough to suggest innovative ways to do their work faster and better. A similar pattern often operates within businesses. In many cases, a business that focuses on one or a few products (sometimes called its “core competency”) is more successful than firms that try to make a wide range of products. Third, specialisation allows businesses to take advantage of economies of scale, which means that for many goods, as the level of production increases, the average cost of producing each individual unit declines . For example, if a factory produces only 100 cars per year, each car will be quite expensive to make on average. However, if a factory produces 50,000 cars each year, then it can set up an assembly line with huge machines and workers performing specialized tasks, and the average cost of production per car will be lower. The ultimate result of workers who can focus on their preferences and talents, learn to do their specialised jobs better, and work in larger organisations is that society (as a whole) can produce and consume far more than if each person tried to produce all their own goods and services. The division and specialisation of labour has been a force against the problem of scarcity. Trade and Markets Specialisation only makes sense, though, if workers can use the pay, they receive for doing their jobs to purchase the other goods and services that they need. In short, specialisation requires trade. Instead of trying to acquire all the knowledge and skills involved in producing all of the goods and services that you wish to consume, the market allows you to learn a specialised set of skills and then use the pay you receive to buy the goods and services you need or want. This is how the economy has evolved in modern society. PART 3: Why Study Economics? Now that we have gotten an overview on what economics studies, let’s quickly discuss why you are right to study it. Economics is not primarily a collection of facts to be memorized, though there are plenty of important concepts to be learned. Economics is better thought of as a collection of questions to be answered or puzzles to be worked out. Most importantly, economics provides the tools to work out those puzzles. If you have yet to be bitten by the economics “bug,” there are other reasons why you should study economics. Virtually every major problem facing the world today, from global warming, to world poverty, to the conflicts in Syria, Afghanistan, and Somalia, has an economic dimension. If you are going to be part of solving those problems, you need to be able to understand them. Economics is crucial. It is hard to overstate the importance of economics to good citizenship. You need to be able to vote intelligently on budgets, regulations, and laws in general. When the Australian Government had to make tough economic and financial decisions during the “Covid lockdowns” in 2020, what were the issues involved? Did you know? A basic understanding of economics makes you a well-rounded thinker. When you read articles about economic issues, you will understand and be able to evaluate the writer’s argument. When you hear classmates, co-workers, or political candidates talking about economics, you will be able to distinguish between common sense and nonsense. You will find new ways of thinking about current events and about personal and business decisions, as well as current events and politics. The study of economics does not dictate the answers, but it can illuminate the different choices.

WHAT are the four factors of production? Answer: Land, Labour, Capital, and Enterprise (or Entrepreneurship). Easy! You've learnt this in class and can explain each of the the factors. And you know that the four factors are all required (in different combinations) to make different goods and services. So let's go deeper .... Economic Activity versus Economic Growth (and the factors of production) I believe that being able to distinguish between economic activity and economic growth this is one of the most important concepts that you need to understand in your study of economics. Economic activity represents the cyclical changes in the economy (also referred to as the 'short-run'). Sometimes economies are expanding / expansionary phase (as households, firms and government buy more goods and services), and sometimes economies are contracting / contractionary phase (as we buy less stuff). At any point in time, the available factors of production are somewhat fixed. For example: available labour is determined by the quantity of labour available to work with appropriate skills, knowledge and experience; land resources are relatively scarce, and generally allocated to a certain production function (eg. agriculture or mining); capital such as machinery and factory size is relatively fixed at a point in time. So the short-run refers to the level of output an economy with the currently available factors of production. In other words, the amount of possible output with a fixed amount of factors of production. Factors of production may not always be utilised to their full capacity When the level of demand in the economy is high, we will see that the available factors of production will be close to fully engaged in the process of making goods and services. For example, labour will have jobs, and we see this when the unemployment rate is low. Factories will be working near to full capacity, and maybe doing overtime shifts. Economy is in an expansionary phase of the economic cycle. If firms can't produce enough G+S to meet demand, they will tend to increase prices of the available stock to maximise profit. We call this demand-push inflation (more on this later). BUT, When the level of demand is low, the available factors of production will not be used to their full extent. For example, some workers will lose their jobs, and the unemployment rate will rise. Factories will cut back on production output, and some machines will not produce to their production capacity. So we will see a contraction in the level of economic activity. The 'ups and downs' in the economy represents changes in the level economic activity, and we refer to these changes as expansionary and contractionary . Economic activity :: data examples 1/3 Economic growth is a sustained increase in the level of output, caused by structural growth in the economy (the long-run). Over time, economies experience an increase in the quantity and quality of the factors of production. For example: Population increases leads to an increase in the quantity of labour Improvements in education and training improves the quality of labour, and workers tend to be more efficient (or productive) in their work. Improvements in technology can increase the level of output given the available resources (factors of production). An increase in capital investment (firms purchasing goods and services - such as additional machinery - to increase the production of final goods and services). What is an example that you can think of?? Eg. how can we improve our land resources to increase agricultural output? Economic growth occurs when an economy: Increases output due to an increase in the available factors of production; and/or Improves productivity - An increase in output the available for a given quantity of the factors of production (factor inputs). Productivity improvements occur when higher quality factor inputs are used (eg. more efficient technology, smarter people etc). Experiences a sustained increase in demand for goods and services, influenced by factors such as population increase, greater levels of international trade etc. Given the relative scarcity of factors of production, economists end to argue that improving productivity is the critical step for economic growth - it means that we are using the current factors of production in a more efficient way. That means that we can leave some factors - resources such as minerals in the ground - so that future generations can access these factors for future production. So the long-run refers to the situation where there is a change (generally an increase or improvement) in at least one of the factors of production. Economies generally exhibit long-run - or structural - economic growth, even though we will experience 'up and downs' in the level of economic activity in the short-run.

Analyse and evaluate the production possibility curve to show the effects of different economic events, e.g. improvements in health, education or productivity of labour, asymmetric technology advances, war and famine. The Production Possibilities Curve (PPC) is the first economic model that you will learn in QCE Economics. In this section, I will focus on how the PPC can be used to illustrate changes in economic activity (short-run / cyclical) and economic growth (long-run / structural) - see the section above to review these concepts. This will also be important for later in Unit 1 when you learn about models for economic (business) cycles - all economic models are connected! If you want to review your calculations of changes in production possibilities, then scroll down for an interactive from our friends at econgraphs.org Image 1: Production possibilities curve Economic activity and the PPC The production decisions of goods and services in an economy falls into two camps: to produce capital (or intermediate) goods and services OR to produce consumer (or final) goods and services. Each economy will make a choice of how to distribute available factors of production to suit the needs and wants of economic stakeholders who purchase goods and services: Consumer goods and services for households Capital goods and services for firms and government The PPC represents the maximum output possible with the current amounts of the factors of production. At a point in time, the factors of production are considered fixed in quantity and quality. In economics, we call this the short-run. This is a really important term - make sure that you remember it. Therefore, the maximum level of output in the short-run would be any point along the PPC. But remember: it is a possibility! When total (aggregate) demand from economic stakeholders (household, firms and governments) is high, economic activity is expansionary, and firms will respond by increasing production, until all factors of production are fully employed. This is represented by a level of output that is on the PPC itself (eg point A in image 1 above). But once at full employment / production on the PPC, firms will struggle to further increase output - they are constrained by the relative scarcity of the factors of production. When an economy experiences contractionary economic activity, production levels may decrease, but the PPC doesn't always shift inwards or outwards. During an economic downturn (contractionary economic activity), firms will respond by reducing output. Firms generally want to produce only the amount of goods and services to meet demand. They don't want to have unsold stock sitting in warehouses. Nor do they want to employ staff when there isn't enough work available. So they will reduce output to meet demand, and this means that the available factors of production are not fully utilised in creating output. In image 2 , this change is demonstrated as a shift in output of consumer goods and services from a value of y to a value less than y, and same for capital goods and services (from x to <x). Total production has decreased from point A to point B. Image 2: Change in production output in a contractionary economy It is important to note that the theoretical production possibilities are unchanged. We still have the factors of production available to produce output anywhere on the PPC, but a decision has been made to decrease output to suit a change in the level of demand in the economy. BUT! The PPC will shift inwards when there is a decrease in availability of input factors (supply-side). For example , the decrease in supply of fuel during the 2026 Iran conflict reduces the capacity of firms to produce and ship goods. Concluding points: Changes in economic output in the short-run (eg from point A to point B) are primarily influenced by changes in demand (purchasing of goods and services by households, firms and governments). The amount of combined purchases across the economy is called Aggregate Demand (more on this later). If Aggregate Demand falls, the economy is contracting . If Aggregate Demand is increasing, the economy is expanding . The fluctuations in the level of of Aggregate Demand is called cyclical economic activity. Economic growth occurs when there is an increase in the quantity or quality of the factors of production Let's start with an example. Since the 1300's, The Netherlands has increased its available land mass by nearly 20%, and most of it with pretty simple technology by today's standards! You can read more about how they did it here . From an economics perspective, the first step in the improvement in factors of production would have been the organisation of the major projects - individual landowners working together for the mutual benefits from the improvements. We can call this enterprise / entrepreneurship in our factors of production framework. Land reclamation in The Netherlands 1300 - today. The increase in land would yield an increase in output (supply) of goods and services. In this instance, likely an increase in agricultural production. The increasing output would also require an increase in labour , which in the short-term is best achieved through migration. Then once you hit an output ceiling, you can increase the quality or quantity of capital - use more machines instead of labour. In The Netherlands agricultural production continues to increase through the use of greenhouses and hydroponic production methods (capital). They are the second largest exporter of agricultural products in the world, which is pretty incredible for a relatively small country! The PPC will shift outwards when there is an increase in the quantity or quality of the factors of production An outward shift of the PPC represents structural, long-run economic growth We know from the examination of cyclical economic activity earlier that the short-run is where all factors of production are fixed in quality and quantity. The long-run is where at least one (but likely all) of the factors of production are variable in quantity or quantity. When an economy, increases the quantity or quality of factors of production, then all production possibilities increase , hence the outward shift of the PPC. Image 3 illustrates this: the original PPC (and production at point A) is the orange curve. As factors of production increase, the curve shifts outwards (blue curve). No production decisions are yet made - all we know is that we have more inputs, or that we use our inputs more efficiently to create more output. An economy could decide to produce in any combination on the blue curve, and overall output is higher. Image 3: Outward shift of PPC represents economic growth The decision to produce at point B would be determined by demand factors such as consumer preference. At production point B: Production of consumer goods and services has increased from y to y1 Production of capital goods and services has increased from x to x1 In the long-run, there is no opportunity cost connected to the decision to increase production of either category of goods. The increase in output is due to either an increase in factor inputs - this is what we call structural (or long-run) economic growth . Concluding points: The level of economic activity (short-run) is generally determined by level of Aggregate Demand in the economy. It will experience expansionary and contractionary phases. It is cyclical in nature. Economic growth (long-run) occurs when there is a sustained increase in level of output in an economy. It is structural in nature. We focus on the longer term trend, rather than short-term fluctuations. Economic growth occurs through: an improvement in quality of factor inputs - productivity improvements (more output for the same quantity of factor inputs) an increase in the quantity of factor inputs - eg. more population leads to more work undertaken, which leads to increased output A sustained increase in demand for goods and services, influenced by factors such as population increase, greater levels of international trade etc. An outwards shift of the PPC represents structural (long-run) economic growth.

Price mechanism :: interactive model How to use the interactive model: use the sliders or drag the curves to view changes in supply of demand use the sliders to visualise changes in price elasticity. the interactive will calculate the new equilibrium positions, as well as determine consumer surplusand producer surplus Why is this stuff important to know? Price equilibrium is a foundational concept in economics that demonstrates market efficiency. This is characterised by: optimum quantity of trade at a price, and where the benefits of trade (welfare) for both consumers and producers are at maximum levels. Economists consider this outcome to reflect the most efficient allocation of scarce resources (allocative efficiency).
