Question 2 Report
A smaller industry that grows to cater for the need of the major industry is
Answer Details
A smaller industry that grows to cater to the needs of a major industry is called a subsidiary industry. It is a type of industry that provides goods or services to support the production and operations of a larger industry.
Subsidiary industries are often dependent on a larger industry for their survival, as they provide inputs, components, or support services that are crucial to the larger industry's production processes. For example, the automotive industry depends on the steel industry for raw materials, and the logistics industry depends on the transportation industry for shipping and handling services.
As the larger industry grows, so too does the demand for the goods and services provided by the subsidiary industry. This can create new business opportunities for entrepreneurs looking to enter the market, as well as generate jobs and economic growth for the region.
Subsidiary industries can also play a key role in the development of an economy, especially in developing countries where new industries may need support to get off the ground. By nurturing and investing in these industries, governments can help create new jobs, build up the infrastructure and supply chain, and create a more diverse and robust economy over time.
Question 3 Report
All the following are problems identified with agriculture in West Africa except
Answer Details
The option "provision of food for the teeming population" is not a problem identified with agriculture in West Africa. It is a challenge, but not a problem in the sense that it is not necessarily a failure or a flaw in the agricultural system. Rather, it is a demand that the agricultural sector must meet.
The other options listed, such as the land tenure system, ignorance of the farmers, and the use of crude implements, are problems in that they limit the ability of the agricultural sector to meet the demand for food. The land tenure system, for example, may not provide clear ownership rights to farmers, making it difficult for them to access credit or make long-term investments in their land. Ignorance of farmers may limit their ability to make use of modern techniques or technologies that could improve yields. The use of crude implements may limit the efficiency and productivity of farming operations. These are all problems in the agricultural sector that need to be addressed to improve food production in West Africa.
Question 4 Report
A monopolist has the power to influence the prices of goods and services. Therefore, he is a
Answer Details
A monopolist has the power to influence the prices of goods and services, therefore he is a price maker. In a market with a monopolist, there is only one seller, who has complete control over the supply of a particular good or service. This means that the monopolist has the ability to set the price for their product, as there is no competition to drive the price down. This is in contrast to a market with many sellers, where the price is determined by the interaction of supply and demand, and individual sellers have limited control over the price. In this case, the seller is considered a price taker, as they must accept the market price determined by supply and demand.
Question 5 Report
A firm that charges the maximum price without attracting competition from new entrants is
Answer Details
A firm that charges the maximum price without attracting competition from new entrants is a monopolistic firm. A monopolistic firm is a market structure in which there is only one seller of a product or service, and the firm has significant control over the price of the product or service. This means that the monopolistic firm can charge a high price without attracting competition from new entrants because there are no other firms selling the same product or service.
It is important to note that a monopolistic firm is different from a perfectly competitive firm, in which there are many firms selling the same product or service, and each firm has limited control over the price. It is also different from a monopolistically competitive firm, in which there are many firms selling similar but differentiated products or services, and each firm has some control over the price.
Question 6 Report
The combination of two commodities each yielding the same level of satisfaction to the consumer is
Answer Details
The combination of two commodities each yielding the same level of satisfaction to the consumer is called an "indifference curve." An indifference curve is a graph that shows all the combinations of two goods that give a consumer the same level of satisfaction. The curve slopes downward, which means that as the amount of one good increases, the amount of the other good needed to maintain the same level of satisfaction decreases. In other words, if a consumer is indifferent between two combinations of goods, they would be just as satisfied with either combination.
Question 8 Report
Petroleum has the following positive contributions to the Nigerian economy except
Answer Details
Petroleum has contributed significantly to the Nigerian economy in various ways. It is a major source of government revenue, and it has created job opportunities for many people in the country. Also, the development of the petroleum industry has led to the establishment of various infrastructure such as roads, bridges, and hospitals, which have benefited the nation.
However, one negative impact of the petroleum industry in Nigeria is that it has led to the development of a mono economy. This means that the economy of Nigeria has become highly dependent on petroleum, which can be risky in the long run as the demand for petroleum may decline or the oil reserves may eventually run out. This over-reliance on oil exports can leave Nigeria's economy vulnerable to external shocks and fluctuations in oil prices, which can have a devastating impact on the country's economic stability.
Therefore, all of the options listed except for "development of mono economy" are positive contributions of the petroleum industry to the Nigerian economy.
Question 9 Report
A line in commodity space which shows the constraints imposed by his budget, his money income and the price of goods purchased is
Answer Details
A Budget Line is a line in commodity space that shows the constraints imposed by a person's budget, their money income, and the price of goods they purchase. The budget line represents all the combinations of two goods that a person can purchase with their given money income, assuming the prices of the goods remain constant. The slope of the budget line represents the price ratio of the two goods and its intercept represents the person's money income. In other words, a budget line helps to show how much of each good a person can buy, given their income and the prices of the goods.

Question 11 Report
The practice of selling goods overseas and often below the cost of production is known as
Answer Details
The practice of selling goods overseas at a price lower than what it costs to produce them is known as "dumping". This means that the exporting company is able to sell its goods at a lower price than their competitors in the importing country, often resulting in an unfair advantage. Dumping is usually done to gain a larger market share in the importing country or to get rid of excess inventory. It can harm the local industries in the importing country by making it difficult for them to compete and survive.
Question 12 Report
The financial institution known as a building society is
Answer Details
A building society is a type of financial institution that is focused on providing mortgage loans and savings accounts to individuals. Unlike commercial banks, which offer a wider range of financial products and services, building societies primarily focus on home ownership and saving for the future. Building societies are owned by their members, who are also customers, and aim to serve the needs of their local communities. They operate on a mutual basis, meaning that any profits made are returned to members in the form of better interest rates on savings or lower mortgage rates.
Question 13 Report
Isocost and isoquant can be attributed to
Answer Details
Isocost and isoquant are concepts used in the theory of production, which deals with the relationship between inputs (e.g. labor, capital) and outputs (e.g. goods, services) in the production process.
An isocost line represents all the combinations of inputs that a firm can purchase for a given total cost. The slope of the isocost line represents the relative prices of the inputs.
An isoquant represents all the combinations of inputs that produce the same level of output. The slope of the isoquant represents the marginal rate of technical substitution, which measures the amount of one input that must be given up to produce one more unit of output while keeping the level of the other input constant.
Together, isocost and isoquant lines are used to analyze the cost-minimizing behavior of a firm and the production efficiency of different input combinations.
Question 14 Report
A commercial bank can create money by
Answer Details
A commercial bank can create money by lending to borrowers. When a bank lends money to a borrower, it creates a new deposit in the borrower's account, which is essentially new money. This new deposit is backed by the bank's assets and the promise of the borrower to repay the loan with interest.
This is possible because banks are only required to keep a fraction of their deposits as reserves, known as the reserve requirement. The reserve requirement is set by the central bank and varies by country. When a bank makes a loan, it only needs to keep a fraction of the loan amount as reserves, which allows it to create new money by issuing a loan.
This process is known as the fractional reserve banking system, and it allows banks to create more money than they hold in reserves. However, it also means that banks are exposed to risks if a large number of borrowers default on their loans.

Question 16 Report
A market will be at equilibrium when
Answer Details
A market will be at equilibrium when demand and supply are equal.
In economics, the market equilibrium refers to a situation where the quantity of goods or services demanded by consumers is equal to the quantity of goods or services supplied by producers. In other words, the market is in balance, and there is no excess demand or supply.
When demand is greater than supply, there will be a shortage of goods or services in the market, which will cause prices to rise. On the other hand, when supply is greater than demand, there will be a surplus of goods or services, which will lead to lower prices.
However, when demand and supply are equal, the market is said to be at equilibrium. At this point, the price of goods or services will stabilize, and there will be no pressure for prices to rise or fall. This is because the quantity of goods or services supplied by producers exactly matches the quantity of goods or services that consumers want to buy.
The market equilibrium is an important concept in economics because it provides a stable platform for market transactions to take place, and it ensures that prices are set at a level that is acceptable to both producers and consumers.
Question 17 Report
In the diagram, the consumer budget line shift from JK to GH. What can definitely be deduced from the diagram?
Answer Details
From the given diagram, it can be deduced that there has been a reduction in the price of at least one of the goods A or B, while the price of the other good has remained the same. This is because the consumer budget line has shifted outward, allowing the consumer to purchase more of both goods A and B than before.
However, we cannot deduce whether there has been an increase in the consumer's money income, as the shift in the budget line could also be due to other factors such as a change in prices or the introduction of a new promotion. Additionally, we cannot determine which of the goods A or B has experienced a price reduction, as the diagram does not provide this information.
Question 18 Report
What would be likely to increase inflation in any economy?
Answer Details
Inflation is the general increase in the price level of goods and services in an economy over time. Several factors can cause inflation, but one likely cause is an increase in demand for goods and services.
When there is an increase in demand for goods and services, it can lead to a rise in their prices. If the supply of goods and services does not increase at the same rate as the demand, this can create a shortage, which allows sellers to increase their prices.
Reducing public spending and increasing direct tax can both have a deflationary effect, which means they can reduce inflation. However, controlling excessive import may not necessarily lead to a decrease in inflation, especially if there is still high demand for goods and services within the domestic economy.
Overall, an increase in demand is a likely factor to cause inflation in an economy, while reducing public spending and increasing direct tax can help to control it.

will enhance the existence of mass production.
Question 20 Report
When elasticity is zero, demand curve is
Answer Details
The correct answer is (2) perfectly inelastic.
When the elasticity of demand is zero, it means that there is no change in the quantity demanded of a product, no matter how much the price changes. In other words, consumers are not responsive to changes in price, and they will continue to buy the same amount of the product regardless of its price.
This situation is known as "perfectly inelastic" demand, and it is represented by a vertical demand curve, where the quantity demanded remains constant regardless of changes in price. This type of demand usually occurs for products that have no substitutes or are considered necessities, such as life-saving medicines or vital goods like water or electricity.
In contrast, a perfectly elastic demand curve would be horizontal, meaning that consumers are highly responsive to price changes and would stop buying the product altogether if the price increased even slightly.
Question 21 Report
The concentration of industries in a particular geographical area is
Answer Details
The concentration of industries in a particular geographical area is known as the localization of industries. This means that a certain region has a high number of similar or related industries located close together. This can happen for a variety of reasons, such as access to natural resources, a skilled workforce, favorable government policies, or efficient transportation systems. The result is a cluster of industry activity in a specific area, which can drive economic growth and create job opportunities.
Question 22 Report
All the following are factors that would bring about a change in supply except
Answer Details
The factor that would not bring about a change in supply is the price of the commodity. The price of the commodity would affect the quantity supplied of that commodity, but it would not affect the overall supply of the commodity in the market.
To understand this, it's important to know the difference between supply and quantity supplied. Supply refers to the total amount of a commodity that producers are willing and able to offer for sale in the market at different prices. Quantity supplied, on the other hand, refers to the specific amount of a commodity that a producer is willing to supply at a particular price.
Therefore, a change in the price of a commodity would affect the quantity supplied, but it would not affect the overall supply in the market. For example, if the price of a commodity increases, producers would be willing to supply more of that commodity, which would result in an increase in the quantity supplied. However, the overall supply of the commodity would only change if there were changes in the level of technology, government policy or entry of new firms, which would affect the total amount of the commodity that producers are willing and able to offer for sale in the market at different prices.
Question 23 Report
Which of the following business units can issue shares?
Answer Details
A public limited liability company (PLC) is the only business unit that can issue shares. A PLC is a type of business structure that is owned by shareholders who share in the profits and losses of the company. The owners of a PLC can raise money for the company by issuing and selling shares, which are portions of ownership in the company. This allows the company to raise capital from a large number of individuals, rather than relying on a single source of funding.
A partnership is a type of business structure that is owned by two or more individuals who share in the profits and losses of the business. However, partnerships do not issue shares and do not have shareholders.
A sole proprietorship is a type of business structure that is owned and operated by a single individual. Sole proprietorships do not issue shares and do not have shareholders.
A central bank is not a type of business structure, but rather a type of financial institution. Central banks do not issue shares and do not have shareholders.
Question 24 Report
The tax levied on locally produced goods is
Answer Details
The tax levied on locally produced goods is called "excise duty." This is a tax that is applied to the production or sale of certain goods within a country. It is often used to discourage the consumption of goods that are considered harmful or luxury items. For example, excise duty can be applied to tobacco products, alcohol, and luxury goods like jewelry or expensive cars. The tax is typically included in the price of the goods, and is paid by the manufacturer or seller of the product. The money collected from excise duty goes into the government's general revenue, which can be used for public services like healthcare, education, and infrastructure.

Question 26 Report
Given that the prices and quantities supplied in litres of petrol is
expressed as Qs = 25 + 0 25P.Qs is the quantity supplied and P is price.
Determine the quantity supplied when price per litre is N30
Answer Details
The equation Qs = 25 + 0.25P represents the relationship between the quantity supplied (Qs) of petrol and its price (P).
When the price per litre is N30, we can substitute this value into the equation to find the quantity supplied:
Qs = 25 + 0.25 * 30
Qs = 25 + 7.5
Qs = 32.5
So, the quantity supplied of petrol when the price per litre is N30 is 32.5 litres.
Question 27 Report
The ordinalist approach of utility postulated that utility can be
Answer Details
The ordinalist approach of utility suggests that utility can be ranked or ordered, but it cannot be measured in absolute terms. In other words, we can say that one option provides greater utility than another, but we cannot assign a specific numerical value to the utility itself.
For example, suppose you are choosing between two different types of ice cream: vanilla and chocolate. The ordinalist approach suggests that you might prefer one flavor over the other, but it doesn't try to measure how much you like each flavor. Instead, it simply assumes that you can rank your preferences: you might like vanilla better than chocolate, or vice versa.
This is different from the cardinalist approach, which suggests that utility can be measured in numerical terms (such as "utils" or "happiness units"). The ordinalist approach is often considered more realistic, because it acknowledges that people's preferences and satisfaction are subjective and difficult to measure in absolute terms.

Question 31 Report
The demand and supply functions of commodity x are given as follows: Qd =
20- 2p, Qs = 6p - 12 where p = price, Qd = quantity demanded and Qs =
quantity supplied. Determine the equilibrium price
Answer Details
To find the equilibrium price, we need to find the price at which the quantity demanded (Qd) equals the quantity supplied (Qs). In other words, we need to find the price where the demand and supply curves intersect.
The demand function is Qd = 20 - 2p, which means that as the price (p) increases, the quantity demanded (Qd) decreases. This is because consumers are generally willing to buy less of a product as its price goes up. On the other hand, the supply function is Qs = 6p - 12, which means that as the price (p) increases, the quantity supplied (Qs) also increases. This is because producers are generally willing to sell more of a product as its price goes up.
Now, to find the equilibrium price, we need to set Qd equal to Qs and solve for p. That is:
20 - 2p = 6p - 12
Adding 2p to both sides, we get:
20 = 8p - 12
Adding 12 to both sides, we get:
32 = 8p
Dividing both sides by 8, we get:
p = 4
Therefore, the equilibrium price for commodity X is p = 4. At this price, the quantity demanded (Qd) equals the quantity supplied (Qs), which is:
Qd = 20 - 2p = 20 - 2(4) = 12
Qs = 6p - 12 = 6(4) - 12 = 12
So, at the equilibrium price of 4, the quantity demanded and supplied for commodity X are both 12.
In summary, the equilibrium price is the price at which the quantity demanded equals the quantity supplied. In this case, the equilibrium price for commodity X is 4, and at this price, the quantity demanded and supplied are both 12.
Question 33 Report
In a situation where Mux represent the marginal utility of product X
while Px represent the price respectively. Utility can be maximized when
Answer Details
Utility can be maximized when the marginal utility of a product divided by its price, known as the marginal utility per unit of money spent, is equal across all goods. In other words, utility is maximized when the consumer is spending their limited budget in such a way that the last unit of money spent on each good yields the same marginal utility.
Mathematically, this can be expressed as:
MUX/PX = MUY/PY = MUZ/PZ = ...
Where MUX, MUY, MUZ, etc. represent the marginal utilities of products X, Y, Z, etc., while PX, PY, PZ, etc. represent their respective prices.
To understand this concept in simple terms, consider a situation where you have a limited budget and are trying to decide how to spend it on different goods. If you have $10 and are trying to decide between buying a book for $5 and a movie ticket for $5, you would choose the option that provides the most utility for each dollar spent.
If the marginal utility of the book is higher than the marginal utility of the movie ticket, then you would choose to buy the book. However, if the marginal utility of the movie ticket is higher than the marginal utility of the book, then you would choose to buy the movie ticket.
Ultimately, the goal is to allocate your budget in such a way that the marginal utility per unit of money spent is the same for all goods, which will result in the highest overall level of utility or satisfaction.
Question 34 Report
The relationship between the cost of living and standard of living is
Answer Details
The cost of living and standard of living are related but in opposite ways. The cost of living refers to the average cost of basic necessities such as food, housing, and healthcare, while the standard of living refers to the level of wealth, comfort, and material goods available to individuals or a society.
When the cost of living increases, it becomes more expensive to maintain a certain standard of living. For example, if the cost of food and housing goes up, people may have to spend more money on these basic necessities and may have less money left over to spend on other things like travel, entertainment, or luxury items. This can lead to a lower standard of living for some individuals or families.
Conversely, a lower cost of living can provide an opportunity for individuals or families to improve their standard of living. If the cost of basic necessities is lower, people may be able to afford more material goods or services that can improve their quality of life. For example, they may be able to afford better healthcare, education, or housing.
Therefore, the correct relationship between the cost of living and standard of living is that a lower cost of living can lead to a higher standard of living, while a higher cost of living can lead to a lower standard of living.
Question 36 Report
The term of trade can be expressed as
Answer Details
The correct answer is (4) (Price index of export ÷ Price index of import) × 100.
The term of trade refers to the ratio of the price index of a country's exports to the price index of its imports. In other words, it measures the amount of imports that a country can purchase for a unit of its exports. A higher term of trade means that a country can purchase more imports for a given quantity of its exports, while a lower term of trade means that it can purchase fewer imports.
To calculate the term of trade, we need to divide the price index of a country's exports by the price index of its imports and then multiply the result by 100 to express it as a percentage. So, the formula for the term of trade is (Price index of export ÷ Price index of import) × 100.
Question 37 Report
In which of the following economic systems do we have the means of production and exchange controlled by private individuals
Answer Details
In a capitalist economic system, the means of production and exchange are controlled by private individuals.
Capitalism is an economic system in which the production and distribution of goods and services are mainly owned and operated by private individuals or corporations. These private individuals are motivated by profit and operate in a competitive market where supply and demand determine prices. The government's role in a capitalist system is generally limited, and the economy operates with minimal interference from the state.
In a capitalist system, individuals are free to own and control private property and engage in economic activities such as buying and selling goods and services. The private sector is responsible for creating jobs and generating wealth, which contributes to economic growth. The market is largely self-regulating, and prices are determined by the forces of supply and demand.
One of the main benefits of a capitalist system is that it provides individuals with the opportunity to create and accumulate wealth through their own efforts. However, it can also lead to income inequality and social stratification, as those who have more resources and capital are better able to succeed in the market.
Question 38 Report
From the diagram, determine the profit-maximizing output
Answer Details
To determine the profit-maximizing output from the diagram, we need to look for the point where the marginal revenue (MR) curve intersects with the marginal cost (MC) curve.
In the diagram, the MR curve intersects with the MC curve at point B. At this point, the firm can produce 900 units of output and still maximize its profits. This is because at this point, the marginal cost of producing an additional unit of output is equal to the marginal revenue generated from selling that additional unit of output.
If the firm were to produce more than 900 units, the marginal cost would exceed the marginal revenue, which would decrease the firm's profits. Conversely, if the firm were to produce less than 900 units, the marginal revenue would exceed the marginal cost, which would also decrease the firm's profits.
Therefore, the profit-maximizing output for the firm in the diagram is 900 units of output.
Question 39 Report
Mr. Patrick’s income is N900 while that of Mr. Shodawe is N1,300. if Mr.
Patrick and Shodawe pay N90 and N130 as taxes, the tax system is
Answer Details
The tax system described is progressive.
A progressive tax system is one in which the tax rate increases as income increases. This means that people with higher incomes pay a larger percentage of their income in taxes than people with lower incomes. In the example provided, Mr. Patrick earns less than Mr. Shodawe but pays a smaller amount of tax (N90 vs N130). This implies that the tax rate for Mr. Patrick is lower than that of Mr. Shodawe.
The progressive tax system is designed to redistribute wealth by taking more from those who can afford to pay more and using the revenue to provide social services and support for those who are less fortunate. It is based on the principle of ability to pay, which means that those who have more should contribute more to support the needs of society.
Overall, the progressive tax system is considered to be fairer than other tax systems because it places a greater burden on those who are better off. It helps to reduce income inequality and ensure that everyone contributes to the common good according to their means.
Question 40 Report
Which of the following could be used to measure the efficiency of labour?
Answer Details
The input-output ratio could be used to measure the efficiency of labor. The input-output ratio is a measure of the amount of input required to produce a unit of output. In the case of labor efficiency, the input would be the amount of labor required to produce a unit of output.
By calculating the input-output ratio, we can determine how efficient a firm is in using its labor resources to produce output. A lower input-output ratio indicates that the firm is using its labor resources more efficiently, while a higher input-output ratio indicates that the firm is using its labor resources less efficiently.
In contrast, the rate of inflation, buying more machines, and unemployment rate are not measures of labor efficiency. The rate of inflation measures the rate at which prices are increasing in the economy, while buying more machines could increase productivity but doesn't necessarily measure labor efficiency. The unemployment rate measures the percentage of the labor force that is currently unemployed and seeking employment, which is not a direct measure of labor efficiency.
Therefore, the input-output ratio is the most appropriate measure for assessing the efficiency of labor.
Question 41 Report
The technical relationship between the physical inputs and the physical outputs of a firm is
Answer Details
The technical relationship between the physical inputs and physical outputs of a firm is referred to as the production function. It describes how much output a firm can produce from a given set of inputs, such as labor, capital, and materials.
The production function specifies the maximum amount of output that can be produced using a given combination of inputs. It shows how much output will be produced for every unit of input used, taking into account the efficiency of production processes.
For example, suppose a firm produces shoes using labor, machines, and leather. The production function would describe how many pairs of shoes the firm can produce using different combinations of these inputs. The function might show that doubling the amount of labor and capital invested in production leads to a 50% increase in shoe output.
By understanding the production function, firms can determine the most efficient way to produce a given amount of output, minimizing costs and maximizing profits. The production function also helps economists to understand the relationship between inputs and outputs in a given industry and to analyze trends in productivity over time.

Question 44 Report
The income elasticity of demand of normal goods is
Answer Details
The income elasticity of demand of normal goods is positive.
The income elasticity of demand measures the relationship between changes in income and changes in the demand for a good. A positive income elasticity of demand means that as income increases, the demand for the good also increases. In other words, as people become wealthier, they tend to buy more of the good. Normal goods are those goods for which demand increases as income increases.
In contrast, a negative income elasticity of demand means that as income increases, demand for the good decreases. This is typically the case for inferior goods, which are goods for which demand decreases as income increases.
A zero income elasticity of demand means that changes in income have no effect on demand for the good. This is rare, as most goods are either normal or inferior, and therefore have a positive or negative income elasticity of demand, respectively.
A fixed income elasticity of demand is not a valid concept in economics. The income elasticity of demand is a continuous variable that can take on any positive or negative value, depending on the good in question and the specific circumstances of the market.
Question 45 Report
The theory of comparative cost advantage is associated with
Answer Details
The theory of comparative cost advantage is associated with David Ricardo.
This theory states that countries should specialize in producing and exporting the goods and services for which they have a comparative advantage, meaning that they can produce those goods and services at a lower cost than other countries. By doing so, both countries can benefit from trade and improve their overall economic efficiency and welfare.
In simpler terms, the theory suggests that a country should focus on making and selling the things they are good at making, while buying the things they are not as good at from other countries, so that everyone can benefit from their strengths.
Question 46 Report
Disposable income is total income
Answer Details
Disposable income is total income less tax.
Disposable income is the amount of income that an individual has available for spending or saving after taxes have been paid. It is calculated by subtracting taxes from an individual's total income.
For example, if someone earns a total income of N100,000 per month and pays N20,000 in taxes, their disposable income would be N80,000 (N100,000 - N20,000).
The concept of disposable income is important because it represents the amount of money that an individual has available to spend or save. It takes into account the impact of taxes on an individual's income, which can significantly reduce the amount of money that they have available for other purposes.
In summary, disposable income is the amount of income that an individual has available for spending or saving after taxes have been paid, and it is calculated by subtracting taxes from an individual's total income.
Question 47 Report
In which situation is it likely that the demand for labour would be inelastic?
Answer Details
The demand for labour would likely be inelastic in situations where the demand for the final product that the labour produces is relatively insensitive to changes in the wage rate.
In other words, if the demand for the final product is not affected much by changes in the cost of labour, then the demand for labour would be relatively inelastic. This is because the demand for labour is derived from the demand for the final product. If the demand for the final product is not very responsive to changes in the cost of labour, then the demand for labour will also be less responsive.
For example, in industries such as healthcare and education, the demand for labour is often relatively inelastic because the demand for these services is not very sensitive to changes in the cost of labour. People need healthcare and education regardless of the cost, and therefore the demand for labour in these sectors tends to be relatively stable.
On the other hand, if the demand for the final product that the labour produces is elastic, meaning that the quantity demanded is highly sensitive to changes in the price, then the demand for labour would be relatively elastic as well. This is because if the cost of labour increases, the cost of the final product will also increase, which could lead to a decrease in demand for the product, and therefore a decrease in the demand for labour.
Overall, the demand for labour is influenced by a variety of factors, including the cost of labour, the demand for the final product, and the availability of alternative inputs such as capital.
Question 48 Report
The study of broad economic aggregates is
Answer Details
The study of broad economic aggregates is called macroeconomics. This branch of economics focuses on the behavior of the economy as a whole, rather than on individual markets or businesses. It involves analyzing economic variables such as inflation, employment, gross domestic product (GDP), and national income. Macroeconomics also examines how government policies, such as monetary and fiscal policies, affect the economy. In simpler terms, macroeconomics looks at the big picture of how the economy is doing and how it can be managed to ensure sustainable growth and stability.
Question 49 Report
Calculate the average product when the 2nd labour was employed 12.5
Answer Details
To calculate the average product of labor, we need to divide the total output by the number of units of labor employed.
However, the question doesn't provide any information about the total output or the first labor unit. Therefore, we cannot accurately calculate the average product of labor when the second labor unit was employed at 12.5.
In general, the average product of labor refers to the amount of output produced per unit of labor. If the total output is increasing at a decreasing rate as more labor is employed, then the average product of labor will eventually decrease. On the other hand, if the total output is increasing at an increasing rate as more labor is employed, then the average product of labor will eventually increase.
Without additional information, it's not possible to determine the relationship between the total output and the number of labor units employed. Therefore, we cannot determine the average product of labor when the second labor unit was employed at 12.5.
Question 50 Report
Which of the following is not a type of unemployment
Answer Details
Factory unemployment is not a type of unemployment. The three main types of unemployment are:
- Structural unemployment: occurs when workers' skills become obsolete or are no longer in demand, and they are unable to find jobs in their field.
- Frictional unemployment: occurs when workers are temporarily between jobs, such as when they are searching for new employment or moving from one job to another.
- Mass unemployment: occurs when there are not enough jobs available in the economy to employ all workers who are seeking employment.
These three types of unemployment are widely recognized and studied in the field of economics. Factory unemployment is not a commonly used term in the field of economics and is not considered one of the main types of unemployment.
