It is positioned as a Microeconomics module in Diploma in Management Studies materials.
The same marginal method is used to explain choice, equilibrium, market power and welfare, but the relevant constraint and decision maker change across those settings. The module moves from scarcity and market coordination through consumer and producer choice to market structure and external effects.
A complete microeconomic answer names the decision maker, margin, constraint, counterfactual and welfare boundary before interpreting a diagram or calculation.
Assessment in ECO2101 is distributed as follows: CA001 individual assignment 30%, CA002 class participation 20% and Exam 50% in the July 2026 L02 overview.
The operational assessment conditions matter here.
The July 2026 overview publishes a two-hour Exam; confirm permitted resources and room in Canvas.
What makes ECO2101 demanding is concrete: Keeping movement along a curve separate from a curve shift, then connecting the private optimum to efficiency without silently changing the ceteris-paribus boundary.

Worked example · free
Trace a market response
- 1Shift the market supply curve left.
- 1Locate the new price and quantity intersection.
- 1Separate firm movement along demand from the market shift.
- 1Identify the surplus and welfare effects.
- 1State what changes if the shortage ends.
Key terms
- Scarcity
- Limited resources relative to competing wants require choice. In this chapter it establishes the object needed to connect production possibilities to gains from exchange.
- Opportunity cost
- The value of the best alternative forgone by a choice. It becomes operational when the analysis must connect production possibilities to gains from exchange.
- Comparative advantage
- Lower opportunity cost in an activity relative to another decision maker. Its interpretation stays bounded because a bowed production frontier embeds changing opportunity cost.
- Market equilibrium
- Price and quantity at which planned demand equals planned supply. In this chapter it establishes the object needed to analyse adjustment and welfare around a market equilibrium.
- Consumer surplus
- Difference between willingness to pay and the price paid. It becomes operational when the analysis must analyse adjustment and welfare around a market equilibrium.
- Price elasticity of demand
- Responsiveness of quantity demanded to a percentage change in price. Its interpretation stays bounded because elasticity magnitude depends on the measured interval and ceteris-paribus conditions.
- Marginal utility
- Additional satisfaction associated with one more unit of consumption. In this chapter it establishes the object needed to locate a constrained consumer optimum.
- Budget constraint
- Affordable combinations determined by income and prices. It becomes operational when the analysis must locate a constrained consumer optimum.
- Marginal rate of substitution
- Amount of one good a consumer is willing to give up for another along an indifference curve. Its interpretation stays bounded because preferences alone do not identify a choice without prices and income.
ECO2101 FAQ
Where is the hardest reasoning in Microeconomics?
Keeping movement along a curve separate from a curve shift, then connecting the private optimum to efficiency without silently changing the ceteris-paribus boundary. ECO2101 covers scarcity, demand and supply, equilibrium, elasticity, consumer choice, production, market structure and external effects.
How does assessment work in Microeconomics?
CA001 individual assignment 30%, CA002 class participation 20% and Exam 50% in the July 2026 L02 overview. The July 2026 overview publishes a two-hour Exam; confirm permitted resources and room in Canvas.
What form does the exam or final task take in Microeconomics?
The published July 2026 examination is scheduled for 20 August from 10:00 am to 12:00 pm, a two-hour sitting. Confirm the room, permitted resources and any operational change in Canvas before the exam.
Which pass conditions apply in Microeconomics?
Canvas and current institutional progression rules control module pass conditions. Verify them before submission and examination; this independent resource treats the published weightings as assessment structure, not as evidence of a separate hurdle.
Where should current dates for Microeconomics be confirmed?
CA001 due: 24 July 2026 at 11:59 am; Exam: 20 August 2026, 10:00 am–12:00 pm. Confirm any change and the exact submission setting in the live LMS. CA001 individual assignment 30%, CA002 class participation 20% and Exam 50% in the July 2026 L02 overview.
How should elasticity be used in a market analysis?
Write the percentage-change numerator and denominator, retain the sign for direction, and use magnitude to classify responsiveness before drawing a revenue implication. ECO2101 covers scarcity, demand and supply, equilibrium, elasticity, consumer choice, production, market structure and external effects.
Why can a competitive market outcome still be inefficient?
Efficiency can fail when private buyers or sellers do not bear an external cost or benefit; widen the marginal boundary before comparing market and social quantities.
