WAEC Economics Past Questions and Answers (2020–2024)

These are WAEC-style theory questions. They are not taken word-for-word from any particular year, but they follow the same pattern and level of difficulty you normally see from 2020–2024.

A. Demand and Supply (WAEC)

Define demand.
Answer: Demand is the quantity of a good or service that consumers are willing and able to buy at a given price and time.
State three factors that can increase the demand for bread in a Nigerian city.
Answer: (i) Increase in consumers’ income (ii) Fall in the price of bread (iii) Increase in population (iv) Successful advertisement (any three).
Explain the law of demand.
Answer: The law of demand states that, ceteris paribus, the higher the price of a good, the lower the quantity demanded, and the lower the price, the higher the quantity demanded.
What is a demand schedule?
Answer: A demand schedule is a table that shows the different quantities of a good that a consumer is willing and able to buy at different prices in a given period.
Differentiate between a movement along the demand curve and a shift of the demand curve.
Answer: A movement along the demand curve is a change in quantity demanded caused only by a change in the price of the good, while a shift of the demand curve is a change in demand caused by other factors such as income, taste or price of related goods.
Define supply.
Answer: Supply is the quantity of a good or service that producers are willing and able to offer for sale at a given price and time.
State the law of supply.
Answer: The law of supply states that, ceteris paribus, the higher the price of a good, the higher the quantity supplied, and the lower the price, the lower the quantity supplied.

Answer: (i) Bad weather or flood (ii) Increase in cost of inputs like fertilizer (iii) Higher taxes on farmers (iv) Insecurity in farming areas (any three).
What is equilibrium price?
Answer: Equilibrium price is the price at which quantity demanded equals quantity supplied, so there is neither shortage nor surplus.
Explain what will happen in a market if the ruling price is above the equilibrium price.
Answer: If price is above equilibrium, there will be excess supply; producers will reduce price to clear the surplus, and the market will move back to equilibrium.
Define price elasticity of demand.
Answer: Price elasticity of demand is the degree of responsiveness of quantity demanded of a good to a change in its price.
State two categories of price elasticity of demand with one example each.
Answer: (i) Elastic demand: quantity demanded responds more than proportionately to price change, e.g. luxury clothes. (ii) Inelastic demand: quantity demanded responds less than proportionately to price change, e.g. salt or petrol.
Give two reasons why the demand for petrol in Nigeria is inelastic.
Answer: (i) Few close substitutes for petrol (ii) It is a necessity for transport and electricity for many users.

Differentiate between monopoly and monopolistic competition.
Answer: In monopoly there is only one seller and the product has no close substitutes, while in monopolistic competition there are many sellers producing similar but not identical products and each firm has some control over its own price.
State two advantages of perfect competition to consumers.
Answer: (i) Lower prices because firms are price takers (ii) Better allocation of resources because price equals marginal cost.
State one disadvantage of monopoly to consumers.
Answer: Monopoly may charge high prices and restrict output, leading to exploitation of consumers.

Answer: If government fixes a minimum price above equilibrium price, producers supply more while consumers demand less, so surplus or excess supply is created.
Define utility.

State the law of diminishing marginal utility.
Answer: The law of diminishing marginal utility states that as a consumer continues to consume more units of a commodity, the additional satisfaction from each extra unit eventually decreases.

Exam Tips for WAEC and NECO Economics

How to Answer Economics Theory Questions

Read the question at least twice. Underline key words like “define”, “explain”, “state four”, “distinguish between” and “with the aid of a diagram”.
Start with a correct definition. When the topic has a standard definition, write it in one or two clear sentences before giving points.
Use numbered points. If the question says “state four”, write your answer as (i), (ii), (iii), (iv). Examiners like well-arranged answers.
Write short, direct sentences. Avoid long stories. Go straight to the point in simple English.
Use diagrams where needed. For demand and supply, market structures and cost curves, draw neat diagrams, label all axes and curves clearly.
Relate your answers to Nigeria. Mention Naira, CBN, Nigerian banks, examples of Nigerian companies and local commodities like yam, rice and petrol.
Manage your time. Do not waste too much time on one question. If you are stuck, move to another question and return later.
Follow the instructions on the paper. Answer the required number of questions in each section. Do not answer more or less than required.

Key Economic Terms to Memorize

Many WAEC and NECO questions start with “Define” or “Explain”. Make sure you can write correct, short definitions of these terms:

Demand, supply, equilibrium price, effective demand, elasticity of demand and elasticity of supply.
Utility, marginal utility, opportunity cost, scale of preference.
Perfect competition, monopoly, oligopoly, monopolistic competition.
National income, GDP, GNP, per capita income, economic growth, economic development.
Money, inflation, unemployment, underemployment, interest rate.
Commercial bank, central bank, liquidity, credit, cheque, overdraft.
Public revenue, public expenditure, taxation, direct tax, indirect tax, budget deficit, budget surplus.
International trade, balance of trade, balance of payments, exchange rate, devaluation, protectionism.
Population census, population density, labour force, dependency ratio, migration.

Common Economics Mistakes to Avoid

Writing stories instead of Economics. Some students tell long stories. Examiners want clear, correct Economics points.
Confusing similar terms. Do not mix up balance of trade with balance of payments, or economic growth with economic development.
Ignoring the number of points required. If the question says “state four” and you write only two points, you lose easy marks.
Leaving diagrams unlabelled. A demand and supply diagram without labels like P, Q, D, S and E will not score full marks.
Running away from simple calculations. National income and statistics calculations are usually simple. Practise them instead of skipping them.
Poor handwriting and dirty work. Write neatly, leave spaces between answers and number your answers clearly.
Last-minute reading only. Create a simple reading timetable weeks before the exam and revise topic by topic with past questions.

Conclusion: You Can Pass Economics with Confidence

Economics is a very friendly subject when you know what to read and how to answer questions. By practising many WAEC and NECO-style questions, understanding the most tested topics and avoiding common mistakes, you can enter the exam hall with boldness.

Use this guide regularly: answer the questions in a notebook, mark yourself with the bold answers and correct your weak areas. Combine these questions with your school notes, recommended textbooks and your teacher’s explanations. With steady practice, you can move from fear to confidence and achieve A1 or B2 in Economics. Keep reading, keep practising and believe in yourself — you can do it.
