ECO130 Business Economics
The Complete Exam Bible · S2 2026ECO130 Overview
- Charles Sturt University
- Session 2, 2026
Within Charles Sturt University, ECO130 Business Economics runs the full micro-then-macro sweep in one semester — scarcity, opportunity cost and the production possibilities frontier; demand, supply and elasticity; short- and long-run production and costs; the four market structures from perfect competition to monopoly (with the oligopoly models: kinked demand curve, price leadership, cartels, game theory); market failure, externalities, public goods and the government's tax/subsidy/regulation toolkit; then GDP (nominal vs real), inflation and the CPI, unemployment, the AD-AS model, money and credit creation, interest rate determination, and RBA monetary policy alongside demand- and supply-side fiscal policy.
None of the marks you can actually see come from a written exam paper: 70% is mechanically procedural.
- ECO130 grading 30% Assessment 1 — six fortnightly Kahoot! quizzes (6 × 5%, 10 questions each at 0.5 marks, ONE attempt, 20-minute limit, open Wed 23:59 to Sun 23:59) · 40% Assessment 2 — 10-minute individual oral market-failure presentation (20 marks peer assessment + 20 marks presentation slides) The remaining assessment share and task split must be confirmed in the current official course outline.
- ECO130 task mode Confirm ECO130 exam duration, permitted materials and venue in the current course site and official timetable.
- ECO130 mark trap Assessment 2 is where 40% is won or lost, and the marks are set by peers against a fixed rubric: Clarity of explanation · Application of economic theory · Accuracy of market failure analysis · Quality of economic reasoning · Presentation skills, with academic moderation applied before release. Two structural traps: (a) topic eligibility. Presentations that describe the market and never reach the policy recommendation lose marks on two rubric lines at once.

How ECO130 is assessed
| Component | Weight | Format |
|---|---|---|
| Six Fortnightly Quizzes | 30% | Six quizzes worth 5% each |
| Market-Failure Oral Presentation | 40% | Oral assessment supported by the current task page |
| Final Examination | Weight subject to confirmation | The current Subject Outline and task pages identifies the examination; check your Subject Outline for its weight and conditions |
The retrieved current pages verify 30% of quizzes and a 40% oral assessment. They identify a final examination but do not publish its current weighting. That weighting is subject to confirmation in the current Subject Outline; no percentage is manufactured to force a 100% table, and no hurdle status is inferred from silence.
What ECO130 covers
The sequence opens at Economic Reasoning and Assessment Control, develops its central analytical shift in Market Structures and Strategic Conduct, and closes with Fiscal, Monetary and International Policy.
Economic Reasoning and Assessment Control
scarcity and choice · opportunity cost · positive and normative claims · identify the choice, counterfactual and evidence before drawing a business conclusion02Production Possibilities and Comparative Advantage
production possibilities frontier · comparative advantage · gains from specialisation · compare opportunity costs before recommending specialisation or trade03Demand, Supply and Market Equilibrium
demand and supply · equilibrium price and quantity · surplus and shortage · trace a named shock through the correct curve and into price and quantity04Elasticity and Business Response
price elasticity · income and cross elasticity · revenue implication · connect responsiveness to pricing, product relationship and market evidence05Production, Costs and Scale
short-run production · fixed and variable cost · economies of scale · link marginal production changes to cost behaviour and operating decisions06Market Structures and Strategic Conduct
perfect competition · monopoly and oligopoly · monopolistic competition · diagnose how entry, product differentiation and strategic interaction shape conduct07Market Failure and Government Intervention
externalities · public goods and information · policy instruments · explain the failure mechanism before comparing tax, regulation or market-design responses08GDP, Growth, Inflation and Unemployment
real GDP and growth · inflation · unemployment · interpret macro indicators together rather than using one headline as a welfare verdict09Money, Interest Rates and Financial Decisions
money and banking · interest-rate determination · saving and investment · trace how financing conditions alter consumption, investment and business planning10Fiscal, Monetary and International Policy
fiscal policy · monetary policy · trade and exchange channels · compare policy transmission, timing and side effects in an open economy30% comes from six fortnightly 10-question Kahoot! quizzes (20-minute limit, ONE attempt, and you must type your student number as your Kahoot! name or score zero); 40% comes from standing up in a workshop and giving a 10-minute oral analysis of a real Australian market failure to 2-3 peers who mark you on a Brightspace rubric on the spot, with academic moderation afterwards.
The subject is relentlessly Australian and current — RBA cash-rate targeting, ABS CPI basket weights, the ACCC supermarkets inquiry, Australia Post as legal monopoly, fuel tax credits to miners, the 2025 Productivity Commission report — and convenor Nicola Thomas teaches from her own consulting practice ('I undertook the modelling used in this Infrastructure Victoria webinar').
Delivered across five campuses (Albury, Bathurst, Melbourne, Port Macquarie, Sydney) on Brightspace, set text Holden, Stevenson & Wolfers (2023).
Assessment in ECO130 is distributed as follows: 30% Assessment 1 — six fortnightly Kahoot!
quizzes (6 × 5%, 10 questions each at 0.5 marks, ONE attempt, 20-minute limit, open Wed 23:59 to Sun 23:59) · 40% Assessment 2 — 10-minute individual oral market-failure presentation (20 marks peer assessment + 20 marks presentation slides) The remaining assessment share and task split must be confirmed in the current official course outline.

What makes ECO130 demanding is concrete: Assessment 2 is where 40% is won or lost, and the marks are set by peers against a fixed rubric: Clarity of explanation · Application of economic theory · Accuracy of market failure analysis · Quality of economic reasoning · Presentation skills, with academic moderation applied before release.
Two structural traps: (a) topic eligibility. Presentations that describe the market and never reach the policy recommendation lose marks on two rubric lines at once.

Worked example: Business Economics integrated response
- 1Mark the starting condition or object represented by demand and supply.
- 1Write the change, rule or mechanism supplied by externalities as a verb-led link.
- 1Show how that link reaches production possibilities frontier; do not skip an intermediate actor, quantity or stage.
- 1Answer the task with the completed chain and preserve this limit: A stylised two-good model isolates a mechanism rather than describing every real constraint.
Key terms
- AD–AS model and inflation
- The AD–AS model determines output and the price level from aggregate demand and short- and long-run aggregate supply; inflation is a sustained rise in the general price level rather than one isolated price increase.
- opportunity cost and the production possibilities frontier (PPF)
- Opportunity cost is the value of the best forgone alternative, and a PPF shows the maximum attainable combinations of two outputs given resources and technology, with its slope representing that trade-off.
- price elasticity of demand vs income elasticity, and tax incidence
- Price elasticity measures demand's responsiveness to its own price, income elasticity measures responsiveness to income, and tax incidence describes how a tax burden is divided according to relative demand and supply elasticities.
- explicit vs implicit costs; economic profit vs accounting profit
- Explicit costs are direct monetary payments and implicit costs are opportunity costs of owned resources; accounting profit subtracts explicit costs, while economic profit subtracts both.
- market failure
- Market failure occurs when unregulated market outcomes do not maximise total social surplus, for example because of externalities, public goods, information problems or market power.
- market structure (perfect competition, monopolistic competition, oligopoly, monopoly)
- Market structure classifies industries by the number and size of sellers, product differentiation, barriers to entry and strategic interaction, ranging from perfect competition to monopoly.
- nominal vs real GDP
- Nominal GDP values final domestic output at current prices, whereas real GDP removes price changes by valuing output at constant or chain-linked prices.
- credit creation and the money multiplier
- Credit creation expands deposits when banks lend part of their reserves; in the course's simple required-reserve model, the money multiplier is the reciprocal of the required reserve ratio.
