ECON1001: pass the exams, not just read the notes
Your complete guide to University of Sydney's introductory microeconomics unit. See where the marks are, work real practice questions, and study with an AI tutor that knows ECON1001.
Sia generates ECON1001 practice questions, walks through production and market equilibrium step by step, and quizzes you on the material the exam weights most heavily.
Worked example
A single-price monopolist faces demand P = 200 − 2Q and has total cost TC = 100 + 8Q + Q-squared, so MC = 8 + 2Q. What output maximises profit, and what price does it charge?
For linear demand P = 200 − 2Q, marginal revenue keeps the same intercept and doubles the slope: MR = 200 − 4Q.
Read the price off the demand curve at Q_m = 32: P_m = 200 − 2(32) = 136.
So the profit-maximising monopolist produces Q = 32 and charges P = 136.
The trap: Setting P = MC (200 − 2Q = 8 + 2Q, giving Q = 48 and P = 104) is the efficient competitive outcome, not the monopoly choice. A monopolist sets MR = MC and then prices up on the demand curve, so MR, not price, equals MC. classic slip!
One exam decides 50% of your grade. Emphasises post-midsemester topics (Weeks 7 to 13) but assumes the Weeks 1 to 6 toolkit as prerequisite skills. This whole page is built around that.
Overview
What ECON1001 is, and where it sits
ECON1001 is the University of Sydney's first-year microeconomics gauntlet. It builds the core toolkit of markets: how individual choices under scarcity become market demand and supply, how equilibrium and welfare are set, how to measure responsiveness with elasticity, how the four market structures price and produce, and how taxes, market failures and trade reshape the result. Demand is built from marginal benefit and supply from marginal cost, then that one toolkit runs across the whole semester.
It is moderately mathematical, working in linear demand and supply equations, cost-curve algebra and graphical analysis. The two largest assessments are in person, closed book and AI-prohibited, so formulas and diagrams have to be fully internalised rather than looked up. Assumed knowledge is HSC Mathematics Advanced (Band 4) or equivalent; students without that background are advised to take ECON1003 alongside or beforehand.
The unit is the entry point to the economics major and a quantitative-reasoning foundation for business and commerce degrees. It is prohibited against BUSS1040 and ECON1040, so it occupies the same slot as the Business School microeconomics unit; you cannot take both for credit.

Difficulty & time commitment
Is ECON1001 hard, and how much time does it take?
ECON1001 is manageable if you keep a weekly rhythm and treat the back half as the main event. Across student reviews the pattern is consistent: it starts gently and steepens, and the heaviest assessment is the part that separates grades.

The difficulty curve and the assessment weighting point the same way: the back half is harder and worth more. Front-loading effort there is the highest-return decision in the unit.
Is this unit for you
Who tends to do well, and who tends to struggle
You will likely do well if
- You are comfortable with HSC Mathematics Advanced-level algebra: linear equations, solving simultaneous equations, finding intersection points and reading slopes.
- You practise drawing and re-drawing the core diagrams (demand and supply, cost curves, monopoly MR=MC, the tax wedge, externalities, trade) until they are automatic.
- You do the weekly tutorial problems by hand rather than only watching solutions.
- You can work without a programmable calculator or notes, because the in-semester test and final are closed book.
You may struggle if
- You rely on a programmable calculator or open notes, since the two biggest assessments forbid both.
- You assume HSC economics covers it; reviews warn that the overlap creates false confidence while the maths and graphical rigour go further.
- You leave the post-midsemester block (monopoly through trade) to cram, even though it dominates the 50% final.
- You are shaky on the algebra of intersections and slopes and skip ECON1003 despite lacking the assumed HSC maths.
- Master the Weeks 1 to 6 toolkit early so the heavier Weeks 7 to 13 material has a foundation to stand on.
- Re-derive every formula (MR = a − 2bq, MC through the AVC and ATC minima, elasticity, DWL triangles) rather than memorising, so closed-book recall is reliable.
- Drill past in-semester-test and sample-final problems under timed, no-notes conditions.
- Keep a one-page diagram-and-formula sheet and practise reproducing each graph from a blank set of axes.
Syllabus
The 13 topics, week by week
The exam-weight marker on each topic shows where the marks concentrate. The amber topics carry the highest exam weight.
T1 · Key concepts and comparative advantage
Nguyen & Wait, Ch 1 to 4Choice under scarcity, opportunity cost (explicit and implicit, sunk cost excluded), the marginal rule (act if MB > MC), the production possibility frontier, and absolute versus comparative advantage as the basis for specialising and trading.
T2 · Demand
Nguyen & Wait, Ch 6Willingness to pay as consumer benefit, diminishing marginal benefit, buying until P = MB, the law of demand, movements along versus shifts, and market demand as the horizontal sum of individual demands.
T3 · Production and costs
Nguyen & Wait, Ch 7The production function and marginal product, short run versus long run, economic versus accounting profit, and the cost family: TC = FC + VC, MC, AFC, AVC and the U-shaped ATC, with MC through the AVC and ATC minima.
T4 · Supply
Nguyen & Wait, Ch 8The competitive firm as a price taker (MR = P), selling until P = MC, the firm supply curve as the upward-sloping part of MC, willingness to receive, and market supply as the horizontal sum of firm MC curves.
T5 · Market equilibrium and welfare
Nguyen & Wait, Ch 9Equilibrium where Qd = Qs, excess supply and demand, comparative statics, consumer and producer surplus, total surplus, Pareto efficiency, and why competitive equilibrium maximises total surplus without being fair.
T6 · Elasticity and perfect competition
Nguyen & Wait, Ch 10 to 12Point and arc elasticity, how price elasticity of demand varies along a linear curve, elasticity and revenue, cross-price and income elasticity, and the perfect-competition shutdown rule and long-run zero-profit entry and exit.
T7 · Monopoly I
Nguyen & Wait, Ch 13The single-price monopolist as price maker, MR = a − 2bq for linear demand, profit max at MR = MC, monopoly profit, and the deadweight loss from restricting output below the competitive quantity.
T8 · Price discrimination and monopolistic competition
Nguyen & Wait, Ch 13 to 14First-, second- and third-degree price discrimination, the two-part tariff, natural monopoly and regulation, and monopolistic competition with its long-run tangency, zero profit, price above MC and excess capacity.
T9 · Oligopoly and game theory
Nguyen & Wait, Ch 15Interdependence and collusion, normal-form games, dominant strategies, Nash equilibrium, the prisoners' dilemma and repeated interaction, and sequential games solved by backward induction.
T10 · Price regulation and taxes
Nguyen & Wait, Ch 16Binding price floors and ceilings, per-unit versus ad valorem taxes, the tax wedge, government revenue, deadweight loss, and tax incidence set by relative elasticities rather than who legally remits.
T11 · Externalities
Nguyen & Wait, Ch 17Positive and negative externalities, MSB = MPB + MEB and MSC = MPC + MEC, the resulting over- or under-production and its DWL, the Coase theorem, and Pigovian taxes, subsidies and tradeable permits.
T12 · Public goods and common resources
Nguyen & Wait, Ch 18The excludable-by-rival taxonomy, public goods and the free-rider problem, society's marginal benefit as the vertical sum of individual MB curves, the efficient quantity, and the tragedy of the commons.
T13 · International trade
Nguyen & Wait, Ch 19Autarky versus the world price, importing and exporting and the gains from trade, tariffs and their two deadweight-loss triangles, quotas and tariff-quota equivalence, and the arguments against free trade.
How it's assessed
Assessment structure
| Component | Weight | Format & timing |
|---|---|---|
| Four online quizzes (Week 3 Early Feedback Test plus three scheduled tests) | 20% | Online, AI allowed, cumulative across weeks as topics are covered. Across the semester, with the Early Feedback Test in Week 3. Low-stakes checkpoints; do not let AI do the reasoning, because the in-person assessments are closed book. |
| In-semester test | 30% | In person, closed book, AI prohibited; multiple-choice on a bubblesheet; non-programmable calculator and approved printed bilingual dictionary permitted; no phones or laptops. Mid-semester. Covers pre-midsemester material (Weeks 1 to 6). |
| Final exam | 50% | In person, closed book, AI prohibited. Formal exam period. Emphasises post-midsemester topics (Weeks 7 to 13) but assumes the Weeks 1 to 6 toolkit as prerequisite skills. |
- No explicit numeric pass-hurdle is stated in the materials reviewed; the standard requirement is a weighted average of at least 50%. The final exam alone is the single dominant component at 50%.
- In-semester test is in-person multiple-choice on a bubblesheet; the final is an in-person closed-book written exam weighted toward Weeks 7 to 13
- Calculator policy: Non-programmable calculator permitted in the in-semester test; no programmable calculator or notes in either in-person assessment
This is an exam-cram unit. With the exams at 80% of the grade and the final exam alone at 50%, your result is overwhelmingly decided by how well you perform under time pressure. Emphasises post-midsemester topics (Weeks 7 to 13) but assumes the Weeks 1 to 6 toolkit as prerequisite skills.
How to actually pass it
A weekly rhythm, two checklists, and the traps to avoid
The unit rewards consistency over cramming, and practice over re-reading. Here is the loop that works, then what to have nailed before each exam.
The weekly loop
Before the mid-semester checklist
- Drill pre-midsemester MCQs (demand, costs, supply, equilibrium and welfare, elasticity, perfect competition) under timed closed-book conditions with only a non-programmable calculator.
- Sit the Week 3 Early Feedback Test seriously to calibrate where you stand.
- Reproduce the cost-curve family (FC, VC, AFC, AVC, ATC, MC) and the surplus triangles from memory.
- Practise point and arc elasticity until the formula and the sign reasoning are automatic.
Before the final heaviest topics
- Prioritise Weeks 7 to 13 (monopoly, price discrimination, monopolistic competition, game theory, taxes, externalities, public goods, trade) but rehearse the Weeks 1 to 6 toolkit they depend on.
- Practise computing DWL triangles and welfare areas quickly, since they recur across monopoly, taxes, externalities and trade.
- Rehearse game-theory matrices: find dominant strategies and Nash equilibria fast.
- Work the sample final and past in-semester tests timed, then check method, not just the answer key.
The mistakes that cost marks
AI-assisted habits that collapse closed book. The open online quizzes let you lean on AI, but the in-semester test and final are closed book and AI-prohibited. Use the quizzes to check yourself, not to outsource the reasoning.
False confidence from HSC economics. Overlap with high-school economics masks the heavier maths and graphical rigour. The diagrams and algebra go further than HSC, so do not coast on prior familiarity.
Cramming the post-midsemester block. Monopoly through trade is the bulk of the 50% final. Leaving Weeks 7 to 13 to the end concentrates the hardest material into the worst time to learn it.
Memorising instead of re-deriving. Under closed-book pressure, memorised formulas slip. Being able to re-derive MR = a − 2bq, the AVC and ATC minima and the DWL triangles is far more reliable.

Formula & concept sheet
The vocabulary and formulas you must own
- Opportunity cost
- Value of the next-best forgone alternative; includes explicit and implicit costs but excludes sunk (unrecoverable) costs.
- Comparative advantage
- Producing a good at a lower opportunity cost than another party; the basis for specialisation and gains from trade, distinct from absolute advantage.
- Marginal benefit and marginal cost
- The extra benefit or cost from one more unit; do an activity while MB > MC and stop when MB < MC.
- Consumer and producer surplus
- CS is the area between demand (willingness to pay) and price paid; PS is the area between price received and supply (MC). Total surplus = CS + PS.
- Pareto efficiency
- No one can be made better off without making someone worse off; equivalently, total surplus is maximised. Competitive equilibrium is Pareto efficient but not necessarily fair.
- Price elasticity of demand (PED)
- (dQ/dP)(P/Q); responsiveness of quantity to price. Inelastic between -1 and 0, unit-elastic at -1, elastic below -1; it varies along a linear demand curve.
- Marginal revenue (monopoly)
- The change in total revenue per unit. For linear demand P = a − bq, MR = a − 2bq: same intercept, twice the slope; MR < P for a monopolist.
- Deadweight loss (DWL)
- Lost total surplus from beneficial trades that fail to occur, for example under monopoly, a tax, a binding price control, an externality or a tariff.
- Tax incidence
- Who actually bears a tax. Legal incidence (who remits) is irrelevant; economic incidence depends on relative elasticities, with the more inelastic side bearing more.
- Externality
- A cost or benefit to a third party outside a transaction; MSB = MPB + MEB and MSC = MPC + MEC, causing the market to over- or under-produce.
- Coase theorem
- With well-defined property rights and no transaction costs, private bargaining reaches the efficient outcome regardless of who holds the rights.
- Public good
- Non-excludable and non-rival, so it suffers the free-rider problem; society's MB is the vertical sum of individual MB curves.
- Nash equilibrium
- A strategy profile where each player's strategy is a best response to the others, so no one can gain by deviating unilaterally.
Common acronyms: PPF · MB/MC · AFC/AVC/ATC · MR/MC · PED · CS/PS · DWL · MSB/MSC · MEB/MEC.

Where it fits
Prerequisites, related units & why it matters
No formal prerequisites. Assumed knowledge is HSC Mathematics Advanced (Band 4) or equivalent (or Band E3 in HSC Mathematics Extension 1 or 2); students lacking this should consider ECON1003 concurrently or beforehand. ECON1001 is prohibited against BUSS1040 and ECON1040, so you cannot take it for credit if you have completed one of those.

FAQ
Frequently asked questions
How is ECON1001 assessed?
Four online quizzes worth 20% in total (AI allowed, including a Week 3 Early Feedback Test), a 30% in-person closed-book in-semester test, and a 50% in-person closed-book final exam. AI is prohibited in both in-person components.
Is there a final exam, and what does it cover?
Yes, a 50% in-person closed-book final. It emphasises the post-midsemester topics (Weeks 7 to 13: monopoly, price discrimination, game theory, taxes, externalities, public goods and international trade) but assumes you can still use the Weeks 1 to 6 demand, supply, cost and elasticity toolkit to solve them.
Can I use AI tools or notes?
AI is allowed on the online quizzes (20%) but prohibited in the in-semester test and the final exam, which are both closed book and in person. Relying on AI for the quizzes can backfire when the closed-book assessments arrive.
How much maths is involved?
It is moderately mathematical: linear demand and supply equations, solving for intersections, cost-curve algebra, elasticity calculations and graphical analysis. Assumed knowledge is HSC Mathematics Advanced (Band 4) or equivalent; students without it are advised to take ECON1003 alongside or beforehand.
Can I take this if I have done BUSS1040?
No. ECON1001 is prohibited against BUSS1040 and ECON1040, so you cannot take it for credit if you have completed one of those.
Do I need to buy the textbook?
The set text is Essentials of Microeconomics by Nguyen and Wait, described in the unit materials as recommended but not mandatory and available via the library. Reviews note the unit follows the textbook closely.
