The notion of short-run and long-run periods is responsible for grouping costs into fixed and variable costs. In the short run, some costs are fixed, which means they do not change regardless of how much the firm produces. Examples of fixed costs include rent, salaries, and insurance premiums. However, other costs are variable, which means they change as the firm produces more or less. Examples of variable costs include raw materials, labor, and energy. In the long run, all costs are variable, which means the firm can adjust all of its inputs as it sees fit. Therefore, the distinction between fixed and variable costs is a temporary one that is based on the time horizon being considered. In summary, the notion of short-run and long-run periods is used to group costs into fixed and variable costs, based on whether they are fixed or can vary in response to changes in the level of output.

The statement that is not true of capital income is: "it is calculated as National Income Population." Capital income refers to income earned through investments in assets such as stocks, real estate, and businesses. It is one of the two main categories of income, the other being labor income, which is earned through wages, salaries, and other compensation for work done. Capital income is an important indicator of economic growth and helps to assess the standard of living of a population. It is calculated as the total income earned through investments in assets. It is also used by the United Nations (UN) to assess and assist developing countries in achieving economic growth. However, the statement "it is calculated as National Income Population" is incorrect. Capital income is not calculated by dividing the national income by the population. Rather, it is calculated as the sum of all income earned from capital investments, including interest, dividends, rents, and profits. In summary, capital income is an important indicator of economic growth and helps assess the standard of living. It is calculated as the sum of all income earned from capital investments and is not calculated by dividing the national income by the population.

The purchasing power of the Naira will fall when there is inflation. Inflation happens when the general price level of goods and services in an economy increases over time, making each unit of currency, such as the Naira, worth less in terms of what it can buy. For instance, if the price of a bag of rice increases from 10,000 Naira to 15,000 Naira, the Naira's purchasing power will have decreased, as it can now buy less than it could before. Retrenching workers, changing the colour of the Naira, cutting all salaries and wages, or overvaluing the Naira do not necessarily lead to a fall in its purchasing power. However, if any of these factors contributes to inflation, it could ultimately lead to a decrease in the Naira's purchasing power.

The Nigerian economy can be best described as a mixed economy. This means that it combines elements of both capitalist and socialist economies. In Nigeria, there is private ownership of businesses and individuals are free to engage in economic activities. At the same time, the government plays a significant role in regulating and controlling certain sectors such as the oil industry and utilities. Additionally, the government provides social services such as healthcare and education, which are characteristic of socialist economies. Overall, Nigeria's mixed economy allows for a balance between private enterprise and government intervention to ensure economic growth and social welfare.

When a country has a large labour force, it is beneficial to use a method of production that is labour intensive. This means that the production process relies heavily on the use of labour, rather than on capital, land, or technology. A labour-intensive production method can be advantageous for several reasons. Firstly, in a country with a large labour force, there may be a surplus of available workers, which can make labour relatively inexpensive. By using a labour-intensive production method, firms can take advantage of this surplus labour and reduce their production costs. Secondly, a labour-intensive production method can help to create employment opportunities for a large number of people, which can be especially important in countries with high levels of unemployment or underemployment. Thirdly, a labour-intensive production method can help to develop the skills and capabilities of the labour force. By relying on the use of labour, workers can gain valuable experience and develop new skills, which can improve their productivity and enhance their employability. Overall, a labour-intensive production method can be a useful strategy for countries with a large labour force. By utilizing this method, firms can reduce their production costs, create employment opportunities, and develop the skills and capabilities of their workforce.

The concentration of industries in one place is referred to as the "localization of industries". This means that a large number of industries or factories are located in a particular region or area. The main reason for the localization of industries is to take advantage of certain benefits such as the availability of raw materials, proximity to markets, availability of skilled labor, and access to transportation. By having industries located in close proximity to each other, they can share resources, collaborate on research and development, and benefit from a skilled workforce. The localization of industries can also lead to the development of supporting industries and services, which further strengthens the regional economy.

A change in demand refers to a shift in the demand curve, which shows the relationship between the price of a product and the quantity demanded. It means that the consumers are now willing and able to buy a different quantity of a product at a given price than they were before. All of the factors listed can cause a change in demand except the price of the commodity. The price of the commodity does not cause a shift in the demand curve, but rather a movement along the existing demand curve. The other factors can cause a shift in the demand curve. For example, an increase in consumer income can shift the demand curve for a normal good to the right, indicating that consumers are now willing and able to buy more of the product at every given price. Similarly, a change in population size, consumer taste, or weather condition can also cause a shift in the demand curve. In summary, a change in demand refers to a shift in the demand curve, and the factors that can cause this shift include consumer income, taste, population size, and weather conditions, but not the price of the commodity itself.

One major function of the Central Bank is to control and regulate the money supply in an economy. The Central Bank is the highest monetary authority in a country, and it is responsible for implementing monetary policies that help to maintain economic stability. One of the ways it does this is by controlling the amount of money that is circulating in the economy. This is important because if there is too much money in circulation, it can lead to inflation, and if there is too little money, it can lead to a recession. To control the money supply, the Central Bank can use various tools, such as setting interest rates, regulating the reserve requirements for banks, and buying or selling government securities. By using these tools, the Central Bank can influence the amount of money that is available in the economy, and help to maintain stable prices, employment, and economic growth. In summary, the Central Bank's role in controlling and regulating the money supply is essential to ensuring the stability and growth of an economy.

The country that is not a member of OPEC is Egypt. OPEC stands for the Organization of the Petroleum Exporting Countries, and it is a group of countries that work together to control the production and pricing of oil. OPEC was founded in 1960, and it currently has 13 member countries, including Iran, Venezuela, and the United Arab Emirates. Indonesia was once a member of OPEC, but it suspended its membership in 2016. Egypt, on the other hand, has never been a member of OPEC. While Egypt is a significant oil producer, it is not considered a major exporter of oil. Therefore, it is not a part of the OPEC group.

The Joint Stock Company can be a company whose minimum membership is 2. A Joint Stock Company is a type of business organization that is owned by shareholders who own a portion of the company's stock. These shareholders invest in the company by buying shares, and they receive a portion of the company's profits in the form of dividends. The minimum number of members required to form a Joint Stock Company varies depending on the laws of the country where the company is being registered. However, in many countries, including the United States and the United Kingdom, a Joint Stock Company can be formed with just two members, who are known as the founding shareholders. In some cases, the minimum membership requirement may be higher, depending on the size of the company or the industry it operates in. But in general, a Joint Stock Company can be formed with as few as two members.

One of the greatest demerits of middlemen in Nigeria is that they increase the price of goods and services at will. This means that when middlemen are involved in the process of buying and selling goods, they tend to add an extra cost to the price of the goods, which can make them more expensive for the final consumer. This is because the middlemen want to make a profit, and they do so by increasing the price of the goods. This practice can make it difficult for people to afford basic goods and services, which can negatively impact their standard of living.

The amount of money that can be created by commercial banks is influenced by the legal reserve ratio. This is a regulation set by the central bank that requires commercial banks to hold a certain percentage of their deposits as reserves. The reserves are held in the form of cash or deposits with the central bank. When a bank receives a deposit from a customer, it is required to hold a percentage of that deposit as reserves and can use the rest to make loans or invest in other assets. The amount of money that a bank can lend out is determined by the reserve ratio. For example, if the reserve ratio is 10%, a bank can lend out 90% of the deposit it received. The reserve ratio influences the amount of money that can be created by commercial banks because it limits the amount of money that banks can lend out. If the reserve ratio is high, banks can only lend out a small percentage of their deposits, and if the reserve ratio is low, banks can lend out more. Therefore, the reserve ratio plays a crucial role in determining the amount of money that can be created by commercial banks.

In the context of marketing and supply chain management, agents of distribution are intermediaries that help move products or services from producers to consumers. They are an important part of the distribution process and can include wholesalers, retailers, government agencies, and cooperative societies. However, consumers are not considered agents of distribution. This is because consumers are the end-users of the products or services and do not participate in the movement of products or services from the producer to themselves. Rather, they are the ultimate destination of the distribution process. Wholesalers are intermediaries who purchase goods in bulk from producers and sell them in smaller quantities to retailers or other intermediaries. Retailers, on the other hand, sell products or services directly to consumers. Government agencies can also act as intermediaries in the distribution process, especially in the distribution of goods or services that are controlled by the government. Cooperative societies are organizations formed by individuals with similar interests to pool their resources and work together for their mutual benefit. In summary, all the options listed except consumers can be classified as agents of distribution, as they all play a role in the movement of products or services from producers to consumers.

It is a general belief that inflation in West Africa is not caused by a decrease in money supply. Inflation is a general rise in the price level of goods and services over time, resulting in a decrease in the purchasing power of money. Excessive bank lending, budget deficits, rising incomes, and a shortage of supply are factors that could increase the money supply in an economy, leading to inflation. However, a decrease in the money supply could lead to deflation, which is a general decrease in the price level of goods and services. Deflation is the opposite of inflation, and it is caused by a reduction in the money supply or a decrease in the demand for goods and services. Therefore, a decrease in the money supply is not a factor that causes inflation in West Africa. Instead, excessive bank lending, budget deficits, rising incomes, and a shortage of supply are factors that could increase the money supply, leading to inflation in the region.

A regressive tax is not a good tax system because it does not ensure equity in payment. A tax system is said to be regressive when the percentage of income paid in taxes decreases as the income level increases. In other words, those with lower incomes pay a higher percentage of their income in taxes compared to those with higher incomes. This means that a regressive tax system places a heavier burden on those who can least afford to pay. This system is not fair because those who are wealthy have a lower tax burden, while those who are poor have a higher tax burden. This can exacerbate income inequality and make it more difficult for low-income individuals and families to make ends meet. Additionally, a regressive tax system can reduce the ability of low-income individuals to participate in the economy. If they have less disposable income due to the higher tax burden, they may have less money to spend on goods and services, which can slow down economic growth. In summary, a regressive tax system is not a good tax system because it does not ensure equity in payment. It can exacerbate income inequality, reduce the ability of low-income individuals to participate in the economy, and slow down economic growth.

The price and quantity of crude oil and petrol sold by Nigeria to other countries is fixed by OPEC. OPEC stands for the Organization of the Petroleum Exporting Countries, which is a group of countries that cooperate to regulate the global supply and price of oil. Nigeria is a member of OPEC, and as such, the country follows the organization's agreements on production levels and pricing. OPEC meets regularly to discuss and decide on production quotas, which determine the amount of oil each member country can produce and sell to other countries. Therefore, OPEC plays a significant role in determining the price and quantity of crude oil and petrol that Nigeria sells to other countries.

The country that makes the largest contribution to the International Monetary Fund (IMF) is the United States of America (USA). The IMF is an international organization that helps promote global monetary cooperation, trade, and economic growth. It provides loans to countries experiencing financial difficulties and also provides policy advice, technical assistance, and training to member countries. Each member country contributes to the IMF based on their quota, which is determined by their relative size in the global economy. The USA has the largest quota of all the member countries, which means they contribute the most money to the IMF. In fact, the USA contributes around 17% of the total funds of the IMF, followed by Japan and China. The contributions made by member countries are important for the IMF to carry out its mandate of promoting global monetary cooperation and economic stability. The contributions are used to provide financial assistance to countries in need, as well as to support the day-to-day operations of the IMF.

The option that is not done by the NNPC is "Pricing of crude oil". The NNPC (Nigerian National Petroleum Corporation) is a government-owned oil company in Nigeria responsible for the management of the country's oil and gas resources. The NNPC is involved in the production, refining, exploration, and exploitation of crude oil, but it is not responsible for the pricing of crude oil. The pricing of crude oil is determined by the global market forces of supply and demand, and it is influenced by factors such as production levels, geopolitical events, and economic conditions. While the NNPC may sell crude oil at a negotiated price to buyers, it does not control the global market price of crude oil. Therefore, the correct option is "Pricing of crude oil".

The specific example of an indirect tax that is not included in the list is the poll tax. Indirect taxes are those taxes that are imposed on goods and services rather than on individuals or companies directly. In other words, the burden of the tax is ultimately passed on to the consumer who buys the goods or services. Out of the options given, purchases tax, import duty, export duty, and excise duty are all examples of indirect taxes because they are imposed on goods and services. However, a poll tax is a type of tax that is levied on individuals or households directly, rather than on goods or services. Therefore, it is not an indirect tax but a direct tax. In summary, all of the options except for the poll tax are examples of indirect taxes because they are imposed on goods and services rather than on individuals directly.

Distribution involves the transfer of goods and services from the production centre to the consumers. This means that once goods and services are produced, they need to be moved from where they are produced to the people who need them. The process of distribution involves various activities such as transportation, storage, and handling of goods. The main goal of distribution is to ensure that goods and services are available to consumers at the right time, in the right place, and in the right quantity. This process is essential to the economy as it helps to meet the demands of consumers and improve their standard of living.

A rational consumer tends to do all of the following except buying more at a high price than at a low price. A rational consumer is one who makes choices that maximize their satisfaction or utility while spending their income wisely. When it comes to purchasing goods and services, a rational consumer would choose to buy more when the price is low and less when the price is high. This is in accordance with the law of demand, which states that as the price of a good or service increases, the quantity demanded decreases, and vice versa. In other words, a rational consumer would choose to buy more of a good or service when the price is lower because they can obtain more satisfaction or utility per unit of money spent. Conversely, when the price is higher, they will buy less because the satisfaction or utility per unit of money spent is lower. Therefore, a rational consumer would not buy more at a high price than at a low price because it would not be in their best interest to spend more money for less satisfaction or utility.

When a business has unlimited liability, it means that the owners are personally responsible for all the financial debts of the business. This means that if the business goes bankrupt and owes money to creditors, the owners can be held personally liable for paying back those debts, even if it means that they have to use their personal assets to do so. This is different from limited liability, where the owners are only responsible for the debts of the business up to the amount of their investment in the business. With unlimited liability, the owners have no such protection and are fully responsible for all the debts of the business. Therefore, in summary, unlimited liability means that the owners of a business are personally responsible for all the financial debts of the business, which can result in their personal assets being used to pay off the business's debts.

Limited liability in Economics means that a shareholder's liability in the event of debt or bankruptcy is limited to the amount they have invested in a company. When a company is formed, its owners, also known as shareholders, are not personally responsible for the company's debts or obligations. Instead, they have limited liability, which means that their liability is limited to the amount of money they have invested in the company. If the company incurs a debt or is unable to pay its obligations, the shareholders' personal assets are not at risk. This concept of limited liability is a critical feature of modern economic systems as it encourages investment in businesses. Shareholders are more willing to invest in companies knowing that their personal assets are not at risk. This allows companies to raise funds for expansion or investments, which can create jobs and stimulate economic growth. In summary, limited liability in Economics means that shareholders are not personally responsible for the company's debts or obligations, and their liability is limited to the amount they have invested in the company. This feature encourages investment in businesses, which can stimulate economic growth.

The statement "cheques are legal tender" is not true. Cheques are a type of negotiable instrument that serve as a written order to a bank to pay a specific amount of money from a person's account to another person or organization. However, they are not considered legal tender, which refers to a form of payment that is accepted by law to settle a debt. Legal tender typically includes cash or coins issued by the government, and it is the only form of payment that creditors are required to accept. While cheques are a widely accepted form of payment, they are not considered legal tender, and creditors have the right to refuse them if they choose to do so.

A firm that charges different prices for goods or services that have the same technical qualities is called a discriminating monopoly. This means that the firm has the power to charge different prices to different consumers or groups of consumers, based on factors such as their willingness to pay or their ability to pay. This is different from a perfect competitor, which is a market in which there are many small firms that sell identical products and have no power to set prices. A monopsony is a market in which there is only one buyer and many sellers, while an oligopoly is a market in which there are only a few large firms that dominate the market. A duopoly is a market in which there are only two firms that dominate the market. In summary, a discriminating monopoly is a firm that has the power to charge different prices to different consumers, while the other terms describe different market structures in which firms operate.

The theory of consumer behavior is based on all of the following assumptions except that the consumer is assumed irrational. In fact, the theory assumes that the consumer is rational and seeks to maximize their utility, subject to a budget constraint. This means that consumers make choices based on their preferences and the prices of goods and services, with the goal of maximizing their satisfaction or "utility" within the constraints of their budget. Additionally, the theory assumes that consumer tastes are consistent and that consumers are exposed to more than one commodity, meaning that they have a choice between different goods and services. Overall, the theory of consumer behavior seeks to explain how consumers make choices based on their preferences and available resources.
