Past Paper On Introduction To Microeconomics For Revision
Microeconomics is the study of the “small” units of the economy—individuals, households, and firms. It is the science of decision-making under scarcity. In your introductory exam, you aren’t just memorizing definitions; you are learning to think at the “margin” and understand how prices act as signals in a free market.

To help you move from confusion to clarity, we have analyzed the most frequent quantitative and theoretical questions found in Microeconomics past papers. Use these core concepts to anchor your revision.
Introduction to Microeconomics: Key Revision Q&A
Q1: What is the “Law of Demand” and what causes a shift in the demand curve?
A: The Law of Demand states that, ceteris paribus (all other things being equal), as the price of a good falls, the quantity demanded rises. A change in price causes a movement along the curve. However, a shift in the entire curve is caused by external factors like changes in consumer income, tastes and preferences, or the price of related goods (substitutes and complements).
Q2: Explain the concept of “Price Elasticity of Demand” (PED).
A: PED measures how responsive the quantity demanded is to a change in price.
If $PED > 1$, the good is Elastic (consumers are very sensitive to price changes, like luxury cars).
If $PED < 1$, the good is Inelastic (consumers buy roughly the same amount regardless of price, like insulin or salt).
The formula is:
$$PED = \frac{\% \text{ Change in Quantity Demanded}}{\% \text{ Change in Price}}$$
Q3: What is the “Law of Diminishing Marginal Utility”?
A: This law states that as a consumer consumes more units of a specific commodity, the additional satisfaction (marginal utility) derived from each extra unit decreases. This explains why the demand curve is downward sloping; you are only willing to pay for a second slice of pizza if the price is lower than the first, because the second slice gives you less extra “joy.”
Q4: Differentiate between “Perfect Competition” and “Monopoly.”
A: These are the two extremes of market structures:
Perfect Competition: Many small firms, identical products, no barriers to entry, and firms are “price takers.”
Monopoly: A single seller, unique product, high barriers to entry (like patents or high startup costs), and the firm is a “price maker.”
Q5: What is an “Opportunity Cost”?
A: In economics, the “cost” of something isn’t just the money you pay. The Opportunity Cost is the value of the next best alternative that you must give up to make a choice. If you spend an hour studying Microeconomics, the opportunity cost might be the hour of sleep or work you lost. This is best illustrated by the Production Possibilities Frontier (PPF).
Why You Must Practice with Microeconomics Past Papers
Microeconomics is a visual and mathematical subject. Most exams will require you to draw and label diagrams accurately or calculate equilibrium points where Supply ($S$) equals Demand ($D$).
By practicing with our past papers, you will:
Master Graphing: Practice drawing the “Profit Maximization” point where $MC = MR$ (Marginal Cost equals Marginal Revenue).
Solve Numerical Problems: Get comfortable calculating total, average, and marginal costs.
Identify Market Failures: Practice explaining “Externalities” (like pollution) and why the free market doesn’t always produce the optimal result.
