WAEC Economics 2006 Past Questions & Answers

The study of Economics provides the principles and tools for making rational choices about how to use scarce resources to satisfy unlimited wants. This skill is not just for personal life but is essential for understanding and participating in decisions that affect the whole nation, such as policies on taxation, employment, and trade. Therefore, studying Economics enables individuals to contribute to and make sense of national decisions.

Common mistake: Students often mistakenly choose option C because they believe the main reason to study Economics is to learn how to get rich, but the subject's scope is much broader, focusing on rational decision-making for society as a whole.

The fundamental problem of economics is scarcity, which is the idea that our wants are unlimited but the resources available to satisfy them are limited. This forces individuals and societies to make choices about how to use these scarce resources. Therefore, the conflict between unlimited wants and scarce resources is the origin of most economic problems.

Common mistake: Students might mistakenly choose option B, but an increase in demand for goods is only a problem because the resources needed to produce them are scarce.

A component bar chart is a special type of bar chart where each bar is divided into different sections, with each section representing a different category or component. This allows an economist to show how a total figure is broken down into its parts. For example, you can use it to show the different sources of a country's revenue (e.g., oil, tax, agriculture) all within single bars for different years.

Common mistake: Students often choose 'Bar charts' because it's a familiar tool, but a simple bar chart typically represents only one category of data per bar, unlike a component bar chart which is specifically designed to show several categories within one bar.

In Economics, there are four main factors of production, and each one earns a specific reward for its contribution. Capital, which refers to man-made assets like machinery, tools, and money used in production, earns interest as its reward. This is because capital is often borrowed, and the payment made for borrowing and using it is known as interest.

Common mistake: Students sometimes mistakenly choose 'rent' because they confuse capital with land, but rent is the reward for the use of land and other natural resources.

Economic activities are grouped into three main stages of production. Primary production involves the extraction of raw materials directly from nature, such as from the land or sea. Since mining is the process of getting mineral resources from the ground, it is classified as primary production, along with other activities like farming and fishing.

Common mistake: Students might mistakenly choose secondary production, but this stage involves processing raw materials into finished goods, whereas mining is the initial extraction of those materials.

An entrepreneur is the factor of production responsible for organizing land, labour, and capital to create a business. This person takes on the financial risks of the enterprise in the hope of making a profit. An owner-manager fits this description perfectly because they both own the firm (taking the risk) and actively manage it (organizing the other factors).

Common mistake: Students may mistakenly choose 'employer' because an owner-manager hires staff, but 'entrepreneur' is the correct economic term that includes the crucial roles of risk-bearing and business organization.

To find the average cost, you first need to calculate the total cost by adding the fixed cost and the variable cost. In this case, Total Cost = 800 Naira + 2,700 Naira = 3,500 Naira. Then, you find the average cost by dividing the total cost by the total output. Therefore, Average Cost = 3,500 Naira / 100 units, which gives you 35 Naira.

Common mistake: A common mistake is to only calculate the average variable cost $(2,700 / 100 = 27)$ and forget to also include the average fixed cost $(800 / 100 = 8)$.

Distribution is the process of moving goods from the producer to the final consumer, which is a key part of the supply chain. When there are too many middlemen (like wholesalers and retailers) in this chain, each one adds their own cost and profit margin to the product. This increases the final price for the consumer and can cause delays, which hinders the efficient distribution of goods and services.

Common mistake: Students may misread the word 'hindered' and choose an option that helps distribution, such as 'A. good road network', instead of one that causes a problem.

In Economics, a 'change in quantity demanded' refers specifically to a movement along a fixed demand curve caused only by a change in the price of the good itself. When the price goes down, we move down the curve (quantity demanded increases), and when the price goes up, we move up the curve (quantity demanded decreases). This is different from a 'change in demand', which involves the entire curve shifting due to other factors like income or taste.

Common mistake: Students often mistakenly choose 'a change in demand' because they confuse the specific term for a movement along the curve with the term for a shift of the entire curve.

Middlemen, such as wholesalers and retailers, act as the link between producers and final consumers. Their primary economic function is to move goods from the point of production to the point of consumption, a process known as distribution. This ensures that goods are available in the right place at the right time for consumers to purchase.

Common mistake: Students may mistakenly choose 'exchange' because middlemen buy and sell goods, but their overall role is the entire process of distribution, which makes the final exchange possible.

The geographical distribution of population refers to how people are spread out across a country. Climatic conditions, such as rainfall, temperature, and sunshine, heavily influence where people choose to live and work, especially in activities like farming. Favourable climates attract more people, leading to a higher population in those areas, while harsh climates discourage settlement.

Common mistake: Students often confuse factors affecting population distribution (where people live) with factors affecting population size or growth, like birth rates (Option A), which change the total number of people rather than their location.

Standardization means making all units of a product the same or identical. Large firms use this method because they produce in large quantities (mass production) to reduce the cost of each item. By making every product the same, they can use machines and assembly lines efficiently, which is not usually possible for small firms that may offer customized goods.

Common mistake: Students may mistakenly choose 'wholesalers' because they deal in bulk, but wholesalers are distributors who buy standardized goods from large firms, they do not typically produce them.

Total utility refers to the overall or total amount of satisfaction a consumer derives from consuming a specific quantity of a commodity. The question asks for the definition of the 'amount of satisfaction obtained from the consumption of a commodity', which directly matches the definition of total utility. For example, the total satisfaction you get from eating three meat pies is the sum of the satisfaction from the first, second, and third pie.

Common mistake: Students often confuse total utility with marginal utility, which is the *additional* satisfaction gained from consuming one more unit of the commodity, not the total satisfaction.

An inferior good is a type of good whose demand decreases when the income of consumers increases. This is because as people earn more money, they tend to switch to more expensive or higher-quality substitutes. For example, a person might buy less of a cheap staple food like cassava flakes (garri) and more of rice or pasta as their salary goes up, making garri an inferior good for them. Therefore, the correct definition is that their demand falls as income increases.

Common mistake: Students may mistakenly choose option B, thinking that a fall in demand means the good is no longer wanted at all, but inferior goods are still in demand, just by a smaller amount or by lower-income groups.

The basis of demand is marginal utility because a rational consumer will only buy an additional unit of a good if the satisfaction gained from it is at least equal to the price paid. Therefore, the consumer's willingness to pay for each extra unit, which is determined by its marginal utility, directly forms their individual demand schedule and curve. As you consume more, the marginal utility falls, and so does the price you are willing to pay, which is the law of demand.

Common mistake: Students often mistakenly choose 'diminishing utility' because while the law of diminishing marginal utility explains why the demand curve slopes downwards, it is the marginal utility itself that forms the basis for the consumer's decision to demand a certain quantity at a given price.

This question tests the basic law of demand. The law of demand states that, all other things being equal, the higher the price of a good, the lower the quantity that will be demanded. As a commodity becomes more expensive, consumers are less willing or able to buy it, so the demand for it falls.

Common mistake: Students may confuse the law of demand with the law of supply (where price and quantity supplied are directly related), leading them to incorrectly choose option A.

This situation describes a surplus in the market, where there are more goods available (increased supply) than people want to buy (decreased demand). To sell the excess goods and attract more buyers, sellers must lower the price. Therefore, when quantity supplied increases and quantity demanded decreases, the price of the commodity will fall to reach a new, lower equilibrium.

Common mistake: Students might mistakenly choose 'a rise in price' (A) by confusing the individual effects of supply and demand shifts, or by incorrectly associating more goods in the market with higher value.

In a free market, the price of a commodity is not decided by buyers or sellers alone. It is set at the point where the quantity consumers are willing to buy (demand) equals the quantity producers are willing to sell (supply). This balance, or interaction between the forces of demand and supply, determines the equilibrium price.

Common mistake: Students often mistakenly choose 'law of demand' because it directly relates price and quantity, but they forget that supply is an equally important force in setting the final market price.

The equilibrium price is the natural price where the quantity of a good demanded by consumers equals the quantity supplied by producers. Price control is a government policy that artificially sets the price of a good, either as a maximum price (price ceiling) below the equilibrium or a minimum price (price floor) above the equilibrium. Therefore, price control is the mechanism that fixes prices away from the market equilibrium.

Common mistake: Students may confuse price control with market structures, and wrongly select 'monopolistic competition' because firms in that market have some power to influence price, but this is not the same as a government fixing a price above or below equilibrium.

A debenture is a type of long-term loan that a company takes from the public to raise money, also known as capital. The person who buys a debenture is a debenture holder, and they are essentially a lender to the company. As a reward for lending money, the company pays the debenture holder a fixed regular payment, which is known as interest.

Common mistake: Students might mistakenly confuse a debenture holder with an employee and choose 'salary', but a salary is paid to an employee for their labour, not to a lender for providing capital.

The main difference between a private and a public enterprise is who owns it. A private enterprise is owned by private individuals or groups, while a public enterprise (or public corporation) is owned and controlled by the government on behalf of the citizens. This difference in ownership is the most fundamental distinction from which other differences, like their objectives, arise.

Common mistake: Students often mistakenly choose 'objective of the business' because while it's a key difference (profit vs. welfare), the objective itself is determined by the more fundamental factor, which is who owns the enterprise.

Nominal capital, also known as authorized capital, is the maximum amount of share capital that a company is legally allowed to issue to the public as stated in its official documents. It represents the total value of shares the company can sell to raise money. Therefore, it defines the total potential amount of money to be raised through the issuance of shares.

Common mistake: Students often confuse nominal capital (the total amount a company is *allowed* to raise) with paid-up capital (the amount *actually* received from shareholders), which seems plausible because the question uses the phrase 'money raised'.

The stock exchange is a specialized financial market where securities, such as company shares and government bonds, are bought and sold. This is its primary function, providing a regulated environment for investors to trade and for companies to raise long-term capital. While other institutions like banks may participate, the stock exchange is the central marketplace for these transactions.

Common mistake: Students might mistakenly choose merchant banks because they are also involved in the capital market, but their main role is advising companies and underwriting new share issues, not providing the actual marketplace for trading existing shares.

Public enterprises are businesses set up by the government to achieve specific national goals. These goals include promoting rapid economic development, providing essential services to underdeveloped areas, and controlling natural monopolies to protect citizens. Discouraging investors is a negative outcome that harms the economy, so it would never be a reason for the government to establish a business.

Common mistake: A student might confuse an unintended consequence with a reason; while the presence of a large public enterprise might discourage private investors, it is never the government's objective or reason for creating it.

In a monopoly, the firm faces a downward-sloping demand curve, which is also its average revenue (AR) curve. To sell an additional unit of its product, the monopolist must lower the price for all units sold, not just the extra one. This causes the marginal revenue (MR) gained from selling that extra unit to be less than the price (AR), so the AR curve always lies above the MR curve.

Common mistake: Students often mistakenly choose option D, confusing the monopolist's curves with those of a perfect competitor where the Average Revenue (AR) and Marginal Revenue (MR) curves are the same horizontal line.
