ECX5953: pass the exams, not just read the notes
Your complete guide to Monash University's economics unit. See where the marks are, work real practice questions, and study with an AI tutor that knows ECX5953.
Sia generates ECX5953 practice questions, walks through monopoly and the data of macroeconomics step by step, and quizzes you on the material the exam weights most heavily.
Worked example
A single-price monopolist faces demand P = 100 − 2Q and has constant marginal cost MC = 20. What price maximises profit?
For linear demand P = a − bQ, marginal revenue has the same intercept and twice the slope: MR = 100 − 4Q.
Read the price off the demand curve at Qm = 20: P = 100 − 2(20) = 100 − 40 = 60.
So the profit-maximising price is P = 60 (option index 2).
The trap: Setting P = MC (the competitive rule) gives 100 − 2Q = 20, so Q = 40. That is the efficient, zero-deadweight-loss quantity a competitive market would reach, not the monopolist's choice. A monopolist sets MR = MC, restricts output to Qm = 20 and prices above marginal cost at P = 60. classic slip!
One exam decides 50% of your grade. Covers all 12 topics across both the micro and macro halves. This whole page is built around that.
Overview
What ECX5953 is, and where it sits
ECX5953 is the Monash Business School's graduate-level introduction to economics: a 6-credit-point unit that builds one microeconomic toolkit (scarcity and economic choice, demand and supply, consumer behaviour and elasticity, costs of production and profit maximisation, perfect competition and monopoly) and then adds a full macroeconomic half (aggregate demand and aggregate supply, the money market and monetary policy, fiscal policy, the foreign exchange market, and unemployment and inflation). It assumes no prior economics and is the graduate-coded twin of the undergraduate ECX2953, sharing the same lecture material, textbook and mid-semester test.
The split is an even 50/50: six microeconomics topics across Weeks 1 to 6, then six macroeconomics topics across Weeks 7 to 12. The micro half runs on linear demand and supply equations, the cost curves, and the monopolist's marginal-revenue-equals-marginal-cost rule, all at an introductory level, so the working is algebra-and-graph based rather than calculus-heavy. The macro half brings the data of macroeconomics (GDP and the price level), long-run growth and money, open-economy macroeconomics and the exchange rate, and short-run fluctuations.
ECX5953 is taught as an Active Learning unit, which means tutorial participation is assessed: a 15% in-tutorial presentation runs across the semester alongside two written research assignments. The set text is Principles of Economics, 9th Asia-Pacific edition (Gans, King, Byford and Mankiw), split into its Principles of Microeconomics and Principles of Macroeconomics volumes. It is the assumed-knowledge economics foundation for the rest of a Monash business or commerce postgraduate program.
Difficulty & time commitment
Is ECX5953 hard, and how much time does it take?
ECX5953 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 rearranging linear equations and reading slopes off a graph: demand and supply, cost curves and the monopoly MR = MC diagram are the workhorses of the micro half.
- You redraw the core diagrams (demand and supply, the tax wedge, the externality social-cost gap, monopoly MR = MC, and aggregate demand and supply) from blank axes until they are automatic.
- You do the weekly homework problem sets by hand and self-mark against the posted solutions before the tutorial, rather than only watching worked answers.
- You keep up with the macro half (GDP and the deflator, money and inflation, the exchange rate, and aggregate demand and supply policy), because it is half the unit and is examined only in the final.
You may struggle if
- You let the graduate pace and the no-prerequisites framing lull you into starting late; the introductory content moves quickly and the micro half is over by the Week 7 mid-semester test.
- You treat the macro half as optional because it is not on the mid-semester test, even though it is half the final and the only place it is examined.
- You memorise formulas (MR = a − 2bQ, the deadweight-loss triangle, the GDP deflator, the money quantity equation) instead of being able to re-derive them under closed-test pressure.
- You skip tutorials, even though a graded in-tutorial presentation is 15% of the unit and assumes regular attendance and contribution.
- Master the Weeks 1 to 6 micro toolkit early and sit the 45-question mid-semester test seriously; it is a low-risk 20% (no penalty marks) that also calibrates you for the final.
- Re-derive every result (MR = a − 2bQ, the surplus and deadweight-loss triangles, the GDP deflator, the money quantity theory, and the aggregate-demand-and-supply shifts) rather than memorising it.
- Treat the two research assignments as marks you can bank: plan the video submission early, follow the brief and the coversheet rules exactly, and submit well before the Week 4 and Week 10 deadlines.
- Build one running page of diagrams and formulas covering both halves, and rehearse reproducing each micro graph and each macro relationship from scratch for the all-topics final.

How it's assessed
Assessment structure
| Component | Weight | Format & timing |
|---|---|---|
| In-tutorial presentation | 15% | Individual in-tutorial presentation assessed by your tutor, on campus or in the OnlineRealTime Zoom tutorial. Across the semester, Weeks 2 to 12. Assessed on participation and presentation in tutorials; this is an Active Learning unit where attendance and contribution are graded. |
| Research Assignment 1 | 5% | Individual online submission: a video clip (MP4) plus a signed assignment coversheet, submitted via Moodle. Due Friday of Week 4, 11:55pm. Submitted to and graded by your allocated tutor. |
| Research Assignment 2 | 10% | Individual online submission: a video clip (MP4) plus a signed assignment coversheet, submitted via Moodle. Due Friday of Week 10, 11:55pm. Submitted to and graded by your allocated tutor. |
| Mid-semester test | 20% | 45 multiple-choice questions, 1 mark each (max 45), no penalty marks; 90 minutes within a 12-hour open-access window; one attempt only, no secondary device, no generative AI. Friday of Week 7 (within the open window); an Alternative MST is offered the following week to eligible students. Covers Weeks 1 to 6 (all microeconomics topics). |
| Final exam | 50% | Centrally scheduled examination covering the whole unit. University examination period. Covers all 12 topics across both the micro and macro halves. |
- Pass on a weighted average of at least 50%. No single-component hurdle is stated in the unit materials reviewed.
- The mid-semester test is 45 multiple-choice questions over the micro half (Weeks 1 to 6) with no penalty for wrong answers, so attempt every question. The final exam covers all 12 topics, so the macro half (Weeks 7 to 12), which is not on the mid-semester test, is examined for the first and only time in the final.
- Calculator policy: A calculator is needed for the numeric questions (elasticity, surplus, monopoly and GDP and multiplier arithmetic). Confirm the permitted-calculator model for the test and exam against the official assessment instructions.
This is an exam-cram unit. With the exams at 70% of the grade and the final exam alone at 50%, your result is overwhelmingly decided by how well you perform under time pressure. Covers all 12 topics across both the micro and macro halves.
Final exam timing: approx Nov 2026 (S2 offering, confirm against the official Monash exam timetable). Confirm the exact date and venue on the official exam timetable.
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 the micro topics (demand and supply, elasticity and government policies, welfare and surplus, externalities, cost curves and perfect competition, monopoly) as multiple-choice under timed conditions.
- Practise the MC versus AVC versus ATC geometry and the shut-down and exit rules until they are instant.
- Rehearse elasticity, the total-revenue test, and consumer and producer surplus, since they recur as MCQs.
- Because the mid-semester test has no penalty marks, practise answering all 45 questions inside 90 minutes and never leaving one blank.
Before the final heaviest topics
- Revise the whole unit, both halves: the final covers all twelve topics, and the macro half is examined here for the first time.
- Drill the monopoly MR = MC method, the deadweight-loss and surplus triangles, and the Pigouvian-tax logic from the micro half.
- Rehearse the macro calculations: GDP and the deflator, the CPI and inflation, the quantity theory of money, and the real exchange rate.
- Practise the aggregate-demand-and-supply diagram and the monetary-and-fiscal-policy responses, and be able to argue the Keynesian versus Neoclassical positions.
The mistakes that cost marks
Using P = MC for a monopolist. The competitive rule P = MC gives the efficient outcome, not the monopolist's. A monopolist sets MR = MC, finds the restricted quantity Qm, then reads the price off demand. This single confusion is the most common monopoly error and it cascades into wrong profit and wrong deadweight loss.
Neglecting the macro half. The mid-semester test covers only Weeks 1 to 6, so it is tempting to under-invest in the macro material. But the macro half is six of the twelve topics and is examined for the first and only time in the 50% final, so leaving it late is the costliest mistake in the unit.
Leaving marks on the table in the MST. The mid-semester test has no penalty for wrong answers, so every blank is a guaranteed zero you could have guessed. Attempt all 45 questions and bank the easy ones; it is a 20% component that also previews the final's micro questions.
Treating tutorials as optional. A 15% in-tutorial presentation plus two research assignments mean 30% of the grade is coursework that rewards regular attendance and following the submission brief. Skipping tutorials or rushing the video submissions throws away marks that are easier than exam marks.

Formula & concept sheet
The vocabulary and formulas you must own
- Price elasticity of demand
- Percentage change in quantity demanded divided by the percentage change in price. Demand is elastic if the absolute value exceeds 1 and inelastic if below 1; the total-revenue test follows from it.
- Total, consumer and producer surplus
- Consumer surplus is the area below demand and above price; producer surplus is the area above supply and below price; total surplus is their sum and is maximised at the competitive equilibrium.
- Deadweight loss
- The fall in total surplus caused by a tax, monopoly or other distortion; the triangle between demand and the marginal-cost (or supply) curve over the units no longer traded.
- Pigouvian tax
- For a negative externality, social marginal cost equals private marginal cost plus the marginal external cost; the efficient quantity is where demand meets social marginal cost, and the corrective tax equals the external cost at that quantity.
- Monopoly marginal revenue
- For linear demand P = a − bQ, MR = a − 2bQ: same intercept, twice the slope. Profit is maximised at MR = MC, then the price is read off the demand curve.
- Shut-down and exit rules
- A competitive firm shuts down in the short run if price is below average variable cost (P < AVC) and exits in the long run if price is below average total cost (P < ATC).
- GDP deflator
- 100 times nominal GDP divided by real GDP, where real GDP values output at base-year prices; it measures the overall price level of domestically produced output.
- Consumer price index and inflation
- The CPI tracks the cost of a fixed basket relative to a base year; the inflation rate is the percentage change in the CPI (or the deflator) between periods.
- Quantity theory of money
- M times V equals P times Y. With velocity and output roughly fixed in the long run, growth in the money supply feeds through into the price level and inflation.
- Real exchange rate
- The nominal exchange rate adjusted for relative price levels; it determines the relative price of domestic and foreign goods and drives the trade balance in the open economy.
- Aggregate demand and aggregate supply
- AD slopes down in the price level; short-run AS slopes up while long-run AS is vertical at potential output. Their intersection sets the price level and real output, and policy shifts AD to stabilise short-run fluctuations.

FAQ
Frequently asked questions
Is ECX5953 hard?
It is moderate for a graduate conversion unit. It assumes no prior economics and the content is introductory micro and macro from a standard textbook, but it moves at a postgraduate pace and 70% of the grade sits in two closed assessments: a 20% mid-semester test and a 50% final exam. It is very manageable with consistent weekly practice and by keeping up with the back-loaded macro half.
How is ECX5953 assessed?
There are five components: a 15% in-tutorial presentation across the semester, two written research assignments worth 5% (Week 4) and 10% (Week 10), a 20% mid-semester test in Week 7 covering the micro half, and a 50% final exam covering all twelve topics. You pass on a weighted average of at least 50%, with no single-component hurdle stated in the materials reviewed.
What is the mid-semester test like?
It is 45 multiple-choice questions worth 1 mark each (45 marks total) with no penalty for wrong answers, so you should attempt every question. You have 90 minutes within a 12-hour open-access window, you get one attempt only, you may not use a secondary device, and generative AI is not permitted. It covers Weeks 1 to 6, the whole microeconomics half.
What does the final exam cover?
The final is held in the University examination period and covers all twelve topics across both halves of the unit. Because the macro half (Weeks 7 to 12) is not tested in the mid-semester test, the final is the only assessment where the macro material is examined, so it cannot be left to the last minute.
What textbook do I need?
The set text is Principles of Economics, 9th Asia-Pacific edition, by Gans, King, Byford and Mankiw, used as its Principles of Microeconomics volume for Weeks 1 to 6 and its Principles of Macroeconomics volume for Weeks 7 to 12. Weekly pre-readings and homework problem sets are mapped to specific chapters.
How is ECX5953 different from ECX2953?
ECX5953 is the postgraduate-coded version and ECX2953 is the undergraduate version. They share the same lectures, textbook and mid-semester test, but ECX5953 is delivered at a graduate pace and is the economics unit you take inside a postgraduate business or commerce program.
