Multiple Choice Questions

31. Many African countries are referred to as underdeveloped due to a combination of factors, including low levels of education, poor infrastructure, and reliance on primary sectors. Dependence on agriculture is a common characteristic of underdeveloped economies, often indicating a lack of industrial diversification and vulnerability to external shocks.

• C) dependence on agriculture

32. In a socialist economic system, the means of production (factories, land, resources) are primarily owned and controlled by the state or government, aiming to distribute wealth more equitably.

• B) Government

33. The cost of living in a country is primarily determined by the general level of prices for goods and services that consumers regularly purchase, such as food, housing, transportation, and healthcare.

• C) prices of goods and services

34. An imperfect market characterized by a few dominant producers or sellers of a similar commodity is known as an oligopoly. These firms often have significant market power and may engage in strategic interactions.

• C) oligopoly

35. The theory of international trade based on the principles of comparative cost (or comparative advantage) was famously propounded by David Ricardo. This theory explains how countries can benefit from trade even if one is more efficient in producing all goods.

• D) David Ricardo

36. National income can be measured using three main methods: the income method (sum of all incomes earned), the output method (sum of the value of all goods and services produced), and the expenditure method (sum of all spending on final goods and services).

• A) income, output and expenditure

37. Complementary, composite, and competitive are all recognized types of demand in economics. Nominal demand is not a classification of demand relationships in the same way; "nominal" typically refers to values expressed in current prices without adjusting for inflation.

• D) nominal

38. The purchase of pen and ink is an example of complementary demand because these goods are typically consumed together. The demand for one is directly related to the demand for the other.

• C) complementary

39. When the total utility (TU) a consumer derives from consuming a good reaches its maximum point, the marginal utility (MU) of the last unit consumed is zero. Consuming any more units beyond this point would lead to negative marginal utility and a decrease in total utility.

• A) zero

40. The difference between the maximum amount a consumer is willing to pay for a commodity and the actual price they pay is known as consumer surplus. It represents the benefit consumers receive from purchasing a good at a price lower than their maximum willingness to pay.

• A) consumer surplus

SECTION B - THEORY

Question 1:

a) Step 1: Substitute each price (P) into the demand function $Q_d = 40 - 2P$ to calculate the quantity demanded. * When $P = N1$: $Q_d = 40 - 2(1) = 40 - 2 = 38$ units * When $P = N3$: $Q_d = 40 - 2(3) = 40 - 6 = 34$ units * When $P = N5$: $Q_d = 40 - 2(5) = 40 - 10 = 30$ units * When $P = N7$: $Q_d = 40 - 2(7) = 40 - 14 = 26$ units * When $P = N9$: $Q_d = 40 - 2(9) = 40 - 18 = 22$ units

Step 2: Substitute each price (P) into the supply function $Q_s = 10 + 4P$ to calculate the quantity supplied.
*   When $P = N1$: $Q_s = 10 + 4(1) = 10 + 4 = 14$ units
*   When $P = N3$: $Q_s = 10 + 4(3) = 10 + 12 = 22$ units
*   When $P = N5$: $Q_s = 10 + 4(5) = 10 + 20 = 30$ units
*   When $P = N7$: $Q_s = 10 + 4(7) = 10 + 28 = 38$ units
*   When $P = N9$: $Q_s = 10 + 4(9) = 10 + 36 = 46$ units

b) Step 3: Prepare the demand and supply schedules using the calculated quantities.

Question 2:

a) An industry refers to a group of firms or businesses that produce similar goods or services, or that are involved in similar economic activities.

b) Four types of industries in Nigeria include: * Primary Industry: This sector involves the extraction and production of raw materials directly from natural resources. Examples in Nigeria include the oil and gas industry (extraction of crude oil), agriculture (farming, fishing, forestry), and mining (solid minerals like coal, tin, iron ore). * Secondary Industry: This sector processes raw materials into finished or semi-finished goods. Examples in Nigeria include the manufacturing industry (textiles, food processing, cement production, vehicle assembly) and the construction industry (building infrastructure and housing). * Tertiary Industry (Service Industry): This sector provides services rather than tangible goods. Examples in Nigeria include the financial services industry (banking, insurance), telecommunications, retail and wholesale trade, tourism, and education. * Quaternary Industry: This is a knowledge-based sector that includes services such as information technology, research and development, consulting, and education. While less dominant than the other sectors, Nigeria has a growing tech industry and research institutions that fall into this category.

Question 3:

a) Production in economics refers to the process of combining various material and immaterial inputs (factors of production) to create a good or service that has value and contributes to the satisfaction of human wants. It involves transforming raw materials into finished products or providing services.

b) Four factors that determine the volume of production are: * Availability and Quality of Factors of Production: The quantity and quality of land (natural resources), labor (human effort), capital (machinery, buildings), and entrepreneurship (organizational skills) directly impact how much can be produced. More abundant and higher-quality inputs generally lead to a higher volume of output. * Technology: The level and application of technology significantly influence productivity and the volume of production. Advanced technology can enable more efficient use of resources, faster production processes, and the creation of new products, thereby increasing output. * Efficiency of Management and Organization: Effective management and organizational structures can optimize resource allocation, streamline production processes, and minimize waste. Good management ensures that factors of production are combined in the most productive way, leading to a higher volume of output. * Market Size and Demand: The potential size of the market and the level of demand for a product influence the scale at which firms are willing and able to produce. A larger market and higher demand can justify larger-scale production, leading to a greater volume of goods and services being supplied.

Question 4:

a) Population Density: This refers to the number of people living per unit area of land, typically expressed as people per square kilometer or square mile. It indicates how crowded a region is and can influence resource availability, infrastructure needs, and environmental impact.

b) Ageing/Declining Population: An ageing population occurs when the median age of a country's population rises due to increasing life expectancy and/or declining birth rates. A declining population refers to a sustained decrease in the total number of people in a country, often resulting from birth rates falling below replacement levels and limited immigration. Both can lead to challenges like a shrinking workforce and increased pressure on social welfare systems.

c) Optimum Population: This is an economic concept referring to the ideal population size for a given area, which, when combined with available resources and technology, yields the highest per capita income or the maximum output per head. It is the population level at which the standard of living is maximized.

d) Efficiency of Labour: This refers to the productivity of the workforce, meaning the rate at which labor produces goods and services. It is influenced by factors such as education, training, health, motivation, technology, and working conditions. Higher labor efficiency means more output can be produced with the same amount of labor input.

Question 5:

a) A sole proprietorship is a type of business entity owned and run by one individual, where there is no legal distinction between the owner and the business. The owner personally assumes all profits and losses, and is personally liable for all business debts.

b) Five advantages of sole proprietorship are: * Ease of Formation: It is the simplest and least expensive form of business to establish, requiring minimal legal formalities and paperwork compared to other business structures. * Complete Control: The sole proprietor has full and direct control over all business decisions, operations, and strategies without needing to consult partners or shareholders. * Retention of All Profits: The owner keeps all the profits generated by the business after taxes, providing a direct financial incentive for hard work and success. * Simple Legal Requirements: There are fewer regulatory burdens and compliance requirements for sole proprietorships, making them easier to manage from a legal and administrative standpoint. * Direct Decision-Making: Decisions can be made quickly and implemented immediately, allowing for greater flexibility and responsiveness to market changes without bureaucratic delays.
