Question 1 Rapport
The maximum price is
Détails de la réponse
The maximum price is **P4**. To explain why, we need to understand that the prices are listed in ascending order. This means that **P1** is the lowest price and **P4** is the highest price. When we say "maximum price," we are referring to the highest possible price among the given options. In this case, **P4** is the highest price listed. Therefore, the maximum price is **P4**.
Question 2 Rapport
If commodities X and Y are substitute, their cross elasticity of demand will be
Détails de la réponse
If commodities X and Y are substitutes, the cross elasticity of demand between them will be positive. 
Cross elasticity of demand measures how the quantity demanded of one commodity changes in response to a change in the price of another commodity. When two commodities are substitutes, they serve similar purposes and are considered as alternatives to each other. For example, if the price of commodity X increases, some consumers may switch to commodity Y as a substitute, causing an increase in the quantity demanded of commodity Y. 
The positive cross elasticity of demand reflects this relationship. It means that an increase in the price of commodity X will lead to an increase in the demand for commodity Y, and vice versa. On the other hand, if the cross elasticity of demand were negative, it would indicate that the two commodities are complements, meaning that they are used together and a change in the price of one would result in an opposite change in the demand for the other. 
Therefore, in the case of substitute commodities, the cross elasticity of demand will be positive.

Question 4 Rapport
Which of the following is an example of expansionary monetary policy by the Central Bank of Nigeria?
Détails de la réponse
An example of expansionary monetary policy by the Central Bank of Nigeria is "buying Treasury securities from commercial banks." Expansionary monetary policy is a type of policy implemented by the central bank to stimulate economic growth and increase the supply of money in the economy. This policy is typically used during times of economic downturn or recession to encourage spending and investment. When the Central Bank of Nigeria buys Treasury securities from commercial banks, it injects money into the economy. This increases the amount of money available in the banking system, making it easier for banks to lend to businesses and individuals. By increasing the money supply, the central bank aims to lower interest rates, which in turn encourages borrowing and spending. Lower interest rates mean that businesses and individuals can access credit more easily, leading to increased investment, consumer spending, and economic growth. This expansionary policy can help support economic activity, boost employment, and stimulate overall economic recovery.

Question 6 Rapport
A persistence rise in the prices of inputs will lead to
Détails de la réponse
A persistence rise in the prices of inputs, such as raw materials or labor, can lead to **cost push inflation**. Cost push inflation occurs when the increased costs of production for firms are passed on to consumers in the form of higher prices for goods and services. This can happen when the prices of inputs used in production rise over a sustained period. When input costs increase, businesses often have two options: absorb the increased costs and accept lower profit margins, or pass on the higher costs to consumers by raising prices. If firms choose to raise prices, it can lead to a general increase in the overall price level in the economy. Here's a simple example to help illustrate this concept: Let's say there is a town where the main industry is manufacturing shoes. The cost of leather, which is a key input in shoe production, starts to rise due to factors like high demand or scarcity. In response, shoe manufacturers have to pay more for leather, and this increases their production costs. To maintain their profit margins, the manufacturers decide to increase the prices of shoes they sell to retailers. Now, if the retailers decide to pass on the higher costs to the consumers, the prices of shoes will increase. This can create a ripple effect throughout the economy because consumers will have to spend more money on shoes, reducing their purchasing power for other goods and services. As a result, the overall price level in the economy increases, and this is what we call cost push inflation. It is important to note that cost push inflation is different from demand pull inflation. Demand pull inflation occurs when there is an increase in aggregate demand, leading to an excess of demand over supply. In contrast, cost push inflation is driven by increased production costs. Hyperinflation, on the other hand, is an extreme form of inflation characterized by an uncontrollable increase in prices. It is typically caused by factors like rapid money supply growth or loss of confidence in the currency. Stagflation refers to a situation where there is a combination of high inflation and high unemployment, typically accompanied by low economic growth. This can occur when an economy experiences a supply-side shock, such as a significant increase in the prices of key inputs. In summary, a persistence rise in the prices of inputs can lead to cost push inflation, as firms pass on the increased costs to consumers by raising prices.
Question 7 Rapport
Indicator of underdevelopment is
Détails de la réponse
An indicator of underdevelopment is low per capita income. Per capita income refers to the average income earned by individuals in a country. In underdeveloped countries, the per capita income is generally low, meaning that people have lower incomes on average compared to developed countries. 
Low per capita income is a significant indicator of underdevelopment because it directly affects the standard of living of people within a country. With low income, individuals have limited purchasing power, making it difficult for them to afford basic necessities such as food, clothing, and shelter. This can lead to overall poor living conditions and a lack of access to essential services like healthcare and education.
Additionally, low per capita income also implies limited economic opportunities and a weak economy. It suggests that the country's productivity and industrial development are low, leading to low wages and limited job opportunities. This can result in high levels of poverty and unemployment, further hindering the country's development.
In summary, low per capita income is a crucial indicator of underdevelopment because it reflects the overall economic situation of a country and directly impacts the living conditions and opportunities available to its citizens.
Question 8 Rapport
Calculate the equilibrium level of national income (Y) where Y = C + I + G; C = 100 + 0.75Y; I = 50; G = 200
Détails de la réponse
To calculate the equilibrium level of national income (Y), we start with the equation Y = C + I + G. In this equation, C represents consumption spending, I represents investment spending, and G represents government spending. Now, let's substitute the given values into the equation: C = 100 + 0.75Y I = 50 G = 200 Substituting these values, we get: Y = (100 + 0.75Y) + 50 + 200 To solve for Y, we need to simplify the equation: Y = 100 + 0.75Y + 50 + 200 Combining like terms, we have: Y = 350 + 0.75Y Next, we can solve for Y by isolating it on one side of the equation. To do this, we can subtract 0.75Y from both sides: Y - 0.75Y = 350 Simplifying further, we have: 0.25Y = 350 Finally, we can solve for Y by dividing both sides of the equation by 0.25: Y = 350 / 0.25 Calculating this, we find: Y = 1400 So, the equilibrium level of national income (Y) is 1400.
Question 9 Rapport
Part-time workers who desire full-time employment are:
Détails de la réponse
Part-time workers who desire full-time employment are classified as underemployed and contribute to the unemployment statistic. 
Underemployment refers to a situation where individuals are working fewer hours than they would like or in jobs that do not utilize their skills and qualifications fully. In this case, part-time workers who desire full-time employment are considered underemployed because they are not able to secure the desired amount of work hours.
These underemployed workers contribute to the unemployment statistic because they are actively seeking additional work hours to meet their employment needs. They are considered part of the labor force because they are willing and available to work more hours, but they have not been able to find full-time employment.
It is important to note that not all underemployed workers contribute to the unemployment statistic. Some may choose to work part-time for personal reasons, such as family responsibilities or pursuing education. These individuals, although underemployed, are not actively seeking additional work hours and therefore do not contribute to the unemployment statistic.
However, in the case of individuals who are part-time workers and desire full-time employment, their underemployment status reflects the inadequacy of available job opportunities. They increase the count of unemployed individuals because they are willing and actively searching for additional work.
It is worth mentioning that cyclical unemployment is a different type of unemployment. It occurs when there is a downturn in the economy, causing a decrease in overall demand for goods and services, and subsequently, a decrease in the demand for labor. Cyclical unemployment is not directly related to the part-time workers' desire for full-time employment.

Question 12 Rapport
Détails de la réponse
The measure that represents the natural growth rate of a population is the **Birth rate minus the Death rate**, which is the second option. The natural growth rate of a population refers to the rate at which the population increases or decreases due to births and deaths, without taking into account migration. It solely focuses on the difference between the number of births and the number of deaths occurring within a population during a specific period of time. When the birth rate exceeds the death rate, it results in a positive natural growth rate, meaning the population is increasing. On the other hand, if the death rate is higher than the birth rate, it leads to a negative natural growth rate, indicating a decrease in the population. The first option, "Natural increase - Birth rate + Net migration," takes into account both the birth rate and the net migration (the difference between the number of people migrating into and out of a population in a specific period). This measure considers factors beyond just births and deaths, so it does not accurately represent the natural growth rate. The third option, "Birth rate/Death rate," is a ratio of the birth rate to the death rate. It does not give a measure of the natural growth rate itself, but rather shows the relationship between the number of births and the number of deaths. The fourth option, "Birth + Net migration = Death," suggests an equality between the sum of births and net migration and the number of deaths. This equation does not accurately represent the natural growth rate since it assumes that the number of births and net migration should exactly match the number of deaths, which is unlikely in most populations. Therefore, the most appropriate measure for the natural growth rate of a population is the **Birth rate minus the Death rate**.
Question 13 Rapport
The rate of output per worker (or group of workers) per unit time is called
Détails de la réponse
The correct answer is labour productivity.
Labour productivity refers to the rate at which output is produced by a worker or a group of workers in a given amount of time. It measures how efficiently and effectively workers are using their skills, time, and resources to produce goods or services.
To understand this concept, let's imagine a scenario where we have two workers producing bicycles. Worker A is able to produce 5 complete bicycles in one hour, while Worker B can only produce 3 complete bicycles in the same amount of time.
In this case, Worker A has a higher labour productivity because they are able to produce more output (bicycles) per unit of time (one hour) compared to Worker B.
Labour productivity is an essential measure for companies and economies because it directly impacts their profitability and competitiveness. Higher labour productivity means that more goods or services can be produced using the same amount of resources or in less time. This leads to lower costs per unit and can result in higher profits or the ability to lower prices for customers.
In summary, labour productivity is a measure of how efficiently workers are producing goods or services and is calculated by dividing the total output by the number of workers or the amount of time it took to produce that output.

Détails de la réponse
Economics is often described as a science because it uses scientific methods to explain observed phenomena. Just like other scientific fields, economics relies on gathering data, formulating hypotheses, and conducting experiments to test these hypotheses. However, unlike fields such as physics or chemistry, economics does not rely on laboratory experiments or controlled experiments. Instead, economists analyze real-world data to understand how individuals, businesses, and governments make choices and interact with each other. They use statistical methods to analyze this data and make predictions about how changes in various factors will affect economic outcomes. While it is difficult to accurately predict the behavior of individual human beings, economics aims to make accurate predictions on aggregate behavior, or how groups of people will respond to changes in factors such as prices, taxes, or policies. These predictions are based on the analysis of historical data and the use of economic models, which simplify complex economic interactions. In summary, economics is considered a science because it employs scientific methods to explain observed phenomena, although it does not rely on laboratory experiments or controlled experiments. It uses data analysis, hypothesis testing, and economic models to understand and predict how individuals and groups make economic decisions and interact with each other.

Question 19 Rapport
When a kilogram of carrot is #8.00, 20 kilograms are demanded and when the price decreased to #6.000 per kilogram, 30 kilograms are demanded. The elasticity of demand equals to
Détails de la réponse
To calculate the elasticity of demand, we need to compare the changes in price and quantity demanded. 
First, let's calculate the percentage change in price: 
% change in price = ((new price - old price) / old price) x 100 
% change in price = ((6 - 8) / 8) x 100 
% change in price = (-2 / 8) x 100 
% change in price = -25% 
Next, let's calculate the percentage change in quantity demanded: 
% change in quantity demanded = ((new quantity demanded - old quantity demanded) / old quantity demanded) x 100 
% change in quantity demanded = ((30 - 20) / 20) x 100 
% change in quantity demanded = (10 / 20) x 100 
% change in quantity demanded = 50% 
Now, let's calculate the elasticity of demand: 
Elasticity of demand = % change in quantity demanded / % change in price 
Elasticity of demand = 50% / -25% 
Elasticity of demand = -2 
The elasticity of demand is -2. 
Explanation: 
The negative sign in the elasticity of demand (-2) indicates that the demand for carrots is price elastic. This means that a decrease in price by 1% will lead to a more than proportionate increase in quantity demanded by 2%. In simpler terms, when the price of carrots decreased by 25%, the quantity demanded increased by 50%. 
Therefore, the elasticity of demand is -2, which means that the demand for carrots is price elastic.
But since price elasticity is always represented with a positive number, the answer is 2
Question 20 Rapport
The short run can be defined as the period of time during which
Détails de la réponse
The short run can be defined as the period of time during which at least one of the firm's inputs is fixed. In other words, it is a time frame in which the firm cannot easily or quickly adjust all of its inputs. This means that some resources, such as the size of a factory or the number of employees, cannot be changed in the short run.
During the short run, firms can only adjust their production levels by varying the amount of variable inputs, such as raw materials or utilities. The fixed input, which remains constant in this period, imposes limitations on the firm's ability to increase or decrease its output. This constraint on adjusting all inputs is what distinguishes the short run from the long run, where all inputs can be varied.
It is important to note that the length of the short run can vary depending on the industry and the specific circumstances of the firm. For some businesses, the short run may be a few months, while for others it could be several years. However, what remains consistent is that during the short run, the firm is restricted in its ability to modify certain inputs, which can impact its production and overall performance.
Question 21 Rapport
From the graph above, the consumer is at equilibrium at point
Détails de la réponse
Based on the graph, the consumer is at equilibrium at point k.
Equilibrium is when the quantity demanded by the consumer is equal to the quantity supplied by the market. At equilibrium, there is no shortage or surplus of the goods or services.
Point k on the graph represents the intersection of the demand curve (D) and the supply curve (S). At this point, the quantity demanded (Qd) and the quantity supplied (Qs) are equal.
If the consumer is at any other point on the graph, either to the left or to the right of point k, there would be either a shortage or a surplus of the goods or services. This would mean that the demand and supply are not in balance and the market is not at equilibrium.
Therefore, point k is the correct answer as it represents the position where the consumer is at equilibrium.
Question 22 Rapport
Institutions serving as links between surplus and deficit units can be identified as
Détails de la réponse
Financial intermediaries serve as links between surplus and deficit units in an economy. These intermediaries include banks, credit unions, and other financial institutions. When there is surplus money in the economy, individuals and businesses deposit the excess funds with financial intermediaries. These intermediaries then pool these funds together and make them available to deficit units, such as individuals or businesses in need of loans or financing. Financial intermediaries play a crucial role in the economy by efficiently allocating funds from surplus units to deficit units. They match the needs of borrowers with the resources of savers, helping to facilitate economic growth and development. Tax officers and pension offices, on the other hand, do not serve as direct links between surplus and deficit units. Tax officers collect taxes for the government, while pension offices manage pension funds for retired individuals. Although these entities may indirectly impact the allocation of funds in the economy, their primary roles are different from that of financial intermediaries. Acceptance houses are also not direct links between surplus and deficit units. Acceptance houses provide short-term financing through the purchase of bills of exchange. While they play a role in facilitating trade between businesses, their function is more specific and limited compared to the broader role of financial intermediaries. In summary, financial intermediaries such as banks and credit unions serve as the primary links between surplus and deficit units in an economy. They gather surplus funds from savers and make them available to borrowers, thereby promoting the efficient allocation of resources.

Détails de la réponse
In a two by two model of international trade, it is assumed that **both countries could gain from trade at the same time, but the volume of the gains depends on terms of trade**. This means that both countries can benefit from engaging in trade with each other. Trade allows both countries to specialize in producing and exporting the goods in which they have a comparative advantage, while importing goods that they are less efficient at producing. This leads to increased efficiency and overall economic gains for both countries. However, the volume of the gains from trade depends on the terms of trade between the two countries. The terms of trade refer to the ratio at which the countries exchange their goods. If one country has a higher bargaining power or can produce goods at a lower cost, they may negotiate more favorable terms of trade, leading to a larger volume of gains for that country. On the other hand, if the terms of trade are less favorable, the volume of gains for both countries may be smaller. In summary, while both countries can benefit from trade, the extent of the gains will vary depending on the terms of trade negotiated between them.
Question 26 Rapport
Which of the following is the resultant effect of a fall in the profit margin of producers in an economy?
Détails de la réponse
A fall in the profit margin of producers in an economy will likely result in an increase in unemployment.
When the profit margin of producers decreases, it means that they are earning less profit from their business activities. As a result, they may struggle to cover their costs, sustain their operations, or expand their businesses. To manage their financial situation, producers may need to cut costs, reduce production, or even close down their business altogether.
Reduced production and business closures lead to a decrease in job opportunities and an increase in unemployment. When businesses are not making enough profit, they may need to lay off workers or reduce their workforce in order to cut costs. This means that fewer people will have jobs, resulting in higher unemployment rates.
Additionally, a fall in profit margins can also deter new businesses from entering the market or existing businesses from expanding. This further limits job creation and can exacerbate the unemployment problem.
In summary, a fall in the profit margin of producers in an economy leads to reduced production, business closures, job cuts, and a decrease in job opportunities. Therefore, the most likely resultant effect of such a decline in profit margin is an increase in unemployment.

Détails de la réponse
Macroeconomics focuses on the units of an economy in an aggregative manner, meaning it looks at the economy as a whole rather than focusing on individual units. This helps us understand how different parts of the economy interact and influence each other. 
The correct option is **household, firms, government, corporate sector, and external sector**. Macroeconomics analyzes the behavior and interactions of these units to understand the overall performance of the economy. 
1. **Households**: These are the individual consumers who make up the economy. They play a vital role in determining the consumption and saving patterns that influence economic activities.
2. **Firms**: Firms are the businesses that produce goods and services in the economy. Macroeconomics looks at their investment decisions, production levels, and employment to understand the overall economic growth and productivity.
3. **Government**: The government plays a significant role in macroeconomics. It collects taxes, provides public goods and services, regulates the economy, and influences economic policies such as fiscal and monetary measures to stabilize the economy. 
4. **External sector**: The external sector represents international trade and the flow of goods, services, and capital across borders. Macroeconomics considers factors like exports, imports, exchange rates, and foreign investment to understand the impact of global interactions on the economy.
By examining these units in an aggregative manner, macroeconomics helps us understand how changes in one sector affect the others and ultimately impact the overall performance of the economy.

Détails de la réponse
The principle that specifies that the amount, when, and how to pay tax should be made known to the taxpayer is known as the Principle of Certainty. This principle ensures that taxpayers have a clear understanding of their tax obligations, which includes knowing the amount of tax they owe, the deadline for payment, and the method of payment.
The Principle of Certainty is important because it promotes transparency and accountability in the tax system. By providing clear and specific information to taxpayers, it enables them to accurately calculate and plan for their tax obligations. This helps to avoid confusion or misunderstandings between the taxpayer and the tax authorities.
Furthermore, the Principle of Certainty also ensures fairness and consistency in the tax system. By clearly stating the rules and requirements, it ensures that all taxpayers are treated equally and that there is no ambiguity or room for arbitrary decisions in the tax assessment process.
Overall, the Principle of Certainty provides a solid foundation for the relationship between taxpayers and tax authorities. It establishes clear expectations, promotes compliance, and adds credibility to the tax system.
Question 32 Rapport
The number of people who are qualified to work and who offered themselves for employment are called
Détails de la réponse
The correct term for the number of people who are qualified to work and who offer themselves for employment is the working population. 
The working population refers to the subset of the total population that is actively engaged or seeking employment. It includes individuals who are qualified, available, and willing to work. This encompasses both employed individuals and those who are actively looking for work, such as job seekers. 
The working population is an important measure for understanding the labor market. It helps policymakers, businesses, and economists in assessing the job market's health and determining factors such as employment rates, labor force participation, and unemployment rates. 
Options like "mobility of labor" and "migrant labor" focus on the movement of workers between different locations, which is a related concept but not the same as the total number of qualified individuals available for employment. "Labor turnover" refers to the rate at which workers leave and join a particular company or industry, which is also not synonymous with the working population as a whole. 
Therefore, the working population is the term that correctly describes the number of qualified individuals who are available for employment.
Question 33 Rapport
.............is presently used in Nigeria to measure inflation
Détails de la réponse
The measure that is presently used in Nigeria to measure inflation is the Consumer Price Index (CPI). The CPI is a commonly used indicator worldwide to track changes in the cost of living over time. 
The Consumer Price Index (CPI) measures the average price changes of a basket of goods and services typically purchased by households in a specific country or region. It reflects the price movements of essential items such as food, housing, transportation, healthcare, education, and many other goods and services that people consume regularly. 
The CPI is calculated by collecting price data for various items in the basket and assigning them weights based on their relative importance in household spending. The prices are then compared to a base period, which is usually a specific year. The percentage change in the CPI from the base period indicates the rate of inflation or deflation.
In Nigeria, the CPI is used to monitor and analyze changes in the cost of goods and services, allowing policymakers and economists to assess the impact on consumers' purchasing power and make informed decisions. It helps in determining the effectiveness of government policies, evaluating the performance of the economy, and adjusting wages and prices.
By tracking the CPI, the government can identify if there is an increase in the general level of prices, indicating inflation, or a decrease, indicating deflation. This information helps in formulating monetary and fiscal policies to control inflation rates and maintain price stability.
Overall, the Consumer Price Index (CPI) is the measure currently used in Nigeria to gauge inflation and is crucial in understanding how the cost of living changes over time, impacting the economy and the daily lives of individuals and businesses.

Agriculture accounts for about 60% of the active labour force in West Africa. This is because a large portion of the population in West Africa is engaged in farming and other agricultural activities for their livelihood. The other options are incorrect as agriculture does not account for 60% of the arable land, service sector activities, or the commodity market in West Africa.
Question 36 Rapport
The economies of West African Countries depend majorly on
Détails de la réponse
The economies of West African countries primarily depend on primary products. 
Primary products refer to raw materials or natural resources that are extracted directly from the earth or sea. These resources typically include agricultural products such as crops, livestock, and fisheries, as well as minerals and natural resources like oil, gas, and minerals. 
West African countries, like many developing nations, tend to have economies that are heavily reliant on these primary products. This reliance is due to a combination of factors such as the abundance of natural resources in the region and historical patterns of economic development.
Agriculture plays a significant role in the economies of West African countries, with a large percentage of the population engaged in farming activities. These countries export a variety of agricultural products, including cocoa, coffee, palm oil, cotton, and timber. These exports generate significant revenue and contribute to the overall economic growth of these nations.
Additionally, West Africa is rich in mineral resources such as gold, diamonds, bauxite, and iron ore. The extraction and export of these minerals also contribute to the economic development of these countries.
While some West African countries have started to diversify their economies and develop secondary and tertiary sectors, the primary sector remains a vital component of their economies. However, it is important for these countries to also focus on diversification and value addition to their primary products to reduce their vulnerability to fluctuations in global commodity prices and achieve sustainable growth.
Question 37 Rapport
The demand for a good is price inelastic if
Détails de la réponse
The demand for a good is price inelastic if the price elasticity is less than one. Price elasticity measures how responsive the quantity demanded of a good is to a change in its price. If the price elasticity is less than one, it means that the quantity demanded is not very responsive to changes in price. In other words, a change in price will have a relatively small impact on the quantity demanded. Even if the price increases or decreases, people will still buy a similar amount of the good. This can happen when the good is a necessity or when there are limited substitutes available. For example, if the price of water increases, people will still need to buy a similar amount because water is essential for survival. Similarly, if the price of a specific medication increases, people with no alternative options will still purchase it regardless of the price. Therefore, when the price elasticity is less than one, we say that the demand for the good is price inelastic.

To explain it simply, the MPC tells us the proportion of additional income that is used for consumption rather than saving or other purposes. For example, if the MPC is 0.8, it means that for every additional unit of income, 0.8 units are typically spent on consumption. The MPC can also be understood as the slope of the consumption function. The consumption function is a mathematical relationship between income and consumption. The MPC represents how much consumption changes for a given change in income. In the equation C = C + cYd, the coefficient c represents the MPC. This equation shows that consumption (C) is determined by autonomous consumption (C) plus the product of the MPC (c) and disposable income (Yd). In summary, the MPC is a measure of how much additional income is typically used for consumption. It can be represented as ΔC/ΔY, the slope of the consumption function, or the coefficient c in the consumption equation.
