Palm oil and palm kernel are in

Antwoorddetails

Palm oil and palm kernel are in joint supply. Joint supply refers to a situation in which two or more products are produced together as a result of a single production process. In the case of palm oil and palm kernel, both products are obtained from the same fruit of the oil palm tree. When the fruit is processed, it produces two distinct products: palm oil and palm kernel. Palm oil is obtained from the fleshy outer part of the fruit, while palm kernel is obtained from the inner seed or kernel. Since both products are obtained from the same production process, the quantity of one product that is produced is directly related to the quantity of the other product that is produced. As a result of being in joint supply, the prices of palm oil and palm kernel are interdependent. If the demand for one product increases, this will increase the supply of the other product, which can lower its price. For example, if the demand for palm oil increases, more oil palm fruit will be processed, leading to an increase in the supply of palm kernel and a potential decrease in its price. To summarize, palm oil and palm kernel are in joint supply because they are both obtained from the same production process and the quantity of one product produced is directly related to the quantity of the other product produced. The prices of both products are interdependent, and a change in demand for one product can affect the supply and price of the other product.

A disadvantage of a jont-stock company is

Antwoorddetails

A disadvantage of a joint-stock company is limited control in management by shareholders. In a joint-stock company, shareholders own a portion of the company and can make money by selling their shares for a profit or receiving dividends. However, shareholders do not typically have direct control over the day-to-day management of the company. Instead, a board of directors and executive management team make decisions on behalf of the company. This lack of control in management can be seen as a disadvantage for shareholders who may have different ideas about how the company should be run or who may not agree with the decisions made by the board or executive management team. Additionally, shareholders may not be able to influence the direction of the company as much as they would like. Overall, while joint-stock companies offer benefits such as limited liability for shareholders, this disadvantage in control over management may be a concern for some investors.

Antwoorddetails

The increase in the demand for a commodity may lead to a decrease in the demand for another if both are in competitive demand. When two goods are in competitive demand, they are seen as substitutes for each other, meaning that they can be used for the same purpose. For example, coffee and tea can be seen as substitutes for each other, since both are beverages that can be used to satisfy the same desire for a hot drink. So, if the demand for coffee increases, people may buy more coffee and less tea, because they see coffee as a substitute for tea. Similarly, if the demand for tea increases, people may buy more tea and less coffee, because they see tea as a substitute for coffee. On the other hand, if two goods are in complementary demand, they are often used together. For example, if the demand for cars increases, the demand for gasoline will also increase, since cars require gasoline to run. Similarly, if the demand for smartphones increases, the demand for phone cases may also increase, since people may want to protect their phones. In composite demand, a good has multiple uses, so an increase in demand for one use may not necessarily lead to a decrease in demand for another use. And in the case of goods of the same quality, an increase in demand for one good does not necessarily affect the demand for the other good, since they are not substitutes or complements.

Antwoorddetails

Statutory organizations usually established by Acts of parliament are called public corporations. A public corporation is a type of legal entity that is established by the government through legislation to perform a specific function or provide a particular service to the public. Public corporations can be formed at the national, state, or local level, and can take a variety of forms depending on their specific mandate. While public enterprises are also entities that are owned and controlled by the government, they may not necessarily be established by Acts of parliament. Cooperative societies are typically voluntary organizations formed by individuals or businesses to pool resources and share risks, while joint-stock companies are privately owned businesses that are established to generate profit for their shareholders.

A major characteristic of natural resources is they

Antwoorddetails

A major characteristic of natural resources is that they are free gifts of nature. This means that they are not produced by humans, but are found naturally in the environment. Examples of natural resources include water, air, forests, minerals, and fossil fuels. However, although natural resources are free in the sense that they are not created by humans, their extraction, production, and transportation often involve costs. Additionally, some natural resources may become scarce over time due to overuse or depletion, leading to increased prices and a greater focus on sustainability and conservation efforts.

In a free market economy, the rationing of scarce goods is done principally by?

Antwoorddetails

In a free market economy, the rationing of scarce goods is principally done by the price mechanism. The price of a good is determined by the forces of supply and demand in the market. When the supply of a good is limited and demand for it is high, the price of that good will increase. This higher price will serve as an incentive for producers to increase their supply of the good, and for consumers to reduce their demand for it. As a result, the scarce good will be rationed among consumers based on their willingness to pay the higher price. This process occurs naturally without the need for government intervention or control, and is a key feature of a free market economy.

The pie chart above represent the total population of a school of 1,200. The shaded area of 60∘ shows the population of the underaged pupils.

What is the population of the matured students?

Antwoorddetails

Since the entire pie chart represents the total population of the school, and the shaded area of 60∘ represents the underaged pupils, then the remaining unshaded area of the pie chart must represent the population of matured students. To find the measure of the unshaded area, we can subtract the measure of the shaded area from the total measure of the pie chart, which is 360∘ (since a circle has 360 degrees). So the unshaded area is: 360∘ - 60∘ = 300∘ The unshaded area of 300∘ represents the population of the matured students. To find the actual population of the matured students, we need to convert the 300∘ into a proportion of the total population. The proportion of the matured students is: 300∘ / 360∘ = 5/6 This means that the population of the matured students is 5/6 of the total population of the school, which is: (5/6) x 1200 = 1000 Therefore, the population of the matured students is 1000.

The use of the bank rate, cash ratio and open market operations constitute

Antwoorddetails

The use of the bank rate, cash ratio, and open market operations are tools used in monetary policy. Monetary policy is a set of actions taken by a country's central bank to manage the supply of money and credit in the economy to achieve specific economic goals, such as controlling inflation, stabilizing prices, and promoting economic growth. The bank rate is the interest rate at which commercial banks can borrow money from the central bank. When the central bank increases the bank rate, it becomes more expensive for commercial banks to borrow money, which reduces the amount of money in circulation in the economy. Conversely, when the central bank lowers the bank rate, it becomes cheaper for commercial banks to borrow money, which increases the amount of money in circulation in the economy. The cash ratio is the percentage of deposits that commercial banks are required to hold in reserve with the central bank. When the central bank increases the cash ratio, it reduces the amount of money that commercial banks have available to lend, which reduces the amount of money in circulation in the economy. Conversely, when the central bank lowers the cash ratio, it increases the amount of money that commercial banks have available to lend, which increases the amount of money in circulation in the economy. Open market operations refer to the buying and selling of government securities by the central bank in the open market. When the central bank buys government securities, it injects money into the economy, which increases the amount of money in circulation. Conversely, when the central bank sells government securities, it withdraws money from the economy, which reduces the amount of money in circulation. So, the use of bank rate, cash ratio, and open market operations are all tools used in monetary policy to manage the amount of money in circulation in the economy, with the aim of achieving specific economic goals.

Which of the following activities will not lead to economic growth?

Antwoorddetails

Massive importation of consumer goods will not lead to economic growth. Economic growth refers to an increase in the capacity of an economy to produce goods and services over a period of time. It is measured by the growth in the gross domestic product (GDP) of a country. Massive importation of consumer goods may lead to an increase in consumption, but it does not lead to an increase in the productive capacity of an economy. This is because consumer goods are used for immediate consumption and do not contribute to the production of other goods and services. On the other hand, capital goods like machinery, equipment, and infrastructure are used to produce other goods and services, and their importation can lead to economic growth by increasing the productive capacity of an economy. Intensive capital formation and the use of modern technology also contribute to economic growth by increasing the efficiency and productivity of an economy.

Antwoorddetails

Wholesalers play an important role in the distribution of goods and services because they act as intermediaries between producers and retailers. Wholesalers buy goods in large quantities from producers and then sell them in smaller quantities to retailers. This enables producers to focus on their production process without worrying about marketing and distribution. On the other hand, retailers can buy smaller quantities of goods from wholesalers, which allows them to stock a variety of products without having to buy in bulk. Wholesalers also provide other important services, such as financing and logistics. They may provide credit to both producers and retailers, allowing them to manage their cash flow and invest in their businesses. Additionally, wholesalers can handle the transportation and storage of goods, which can be a complex and expensive task for smaller businesses. Therefore, wholesalers play a crucial role in the distribution process, providing valuable services and enabling the smooth flow of goods and services from producers to retailers, and ultimately to consumers.

An important factor hindering the rapid development of the industrial sector in Nigeria.

Antwoorddetails

An important factor hindering the rapid development of the industrial sector in Nigeria is inadequate infrastructure facilities. This includes factors such as inadequate transportation systems, unreliable electricity supply, poor communication networks, and insufficient access to water and sanitation facilities. These factors can increase the cost of production, reduce productivity and efficiency, and make it difficult for industries to compete with other countries. The dominance of the oil sector has also been a significant factor, as it has led to a neglect of other sectors, including manufacturing and industry. Excessive demand for finished products and rural-urban migration may have some impact on industrial development but are not as significant as inadequate infrastructure and the dominance of the oil sector.

Antwoorddetails

The middlemen is responsible for "breaking the bulk". Middlemen are intermediaries between producers and consumers in the distribution process. They play a crucial role in getting products from the producers to the consumers, and they perform a variety of functions such as transportation, storage, and marketing. One important function of middlemen is to break the bulk of products. This means they take large quantities of goods from producers and break them down into smaller units that can be sold to consumers in the desired quantities. For example, a farmer may produce tons of wheat, but consumers may only want to buy it in small quantities. Middlemen can purchase the bulk quantity from the farmer, then break it down into smaller units that can be sold to individual consumers. Breaking the bulk is important for several reasons. It allows for greater efficiency in the distribution process, as products can be transported and stored more easily in smaller units. It also allows for greater flexibility in meeting consumer demand, as products can be sold in the quantities that consumers desire. Finally, it can help to reduce costs for both producers and consumers, as middlemen can aggregate products from multiple producers and sell them at a lower cost than individual producers could achieve on their own.

Antwoorddetails

The International Bank for Reconstruction and Development (IBRD) as an international monetary institution is concerned with the development of infrastructure in member nations. The IBRD, also known as the World Bank, was established to help finance the reconstruction and development of war-torn and developing countries after World War II. The bank provides loans, technical assistance, and other financial services to support projects in a variety of sectors, including infrastructure development, such as transportation, energy, and communication networks, among others. While the IBRD is concerned with the economic development of member nations, it is not primarily focused on financing private business or improving trade among member nations, although these may be outcomes of its operations. Additionally, the IBRD may also provide assistance to member nations facing balance of payments problems, but this is not its primary objective.

Holding money to take care of contingencies is

Antwoorddetails

Holding money to take care of contingencies is a precautionary motive. This means that people keep money saved in case of unexpected events or emergencies, such as a sudden illness, job loss, or car repair. By having money set aside, they are better prepared to handle these situations and can avoid going into debt or facing financial hardship. In short, holding money for precautionary reasons is a way to protect one's financial security and peace of mind.

Antwoorddetails

The effect of changes in the condition of demand on a demand schedule with the price constant is a shift of the demand curve. When there is a change in any factor that affects the quantity demanded at each price level, such as income, tastes and preferences, prices of related goods, or population, the entire demand curve shifts to a new position. This means that at each price level, the quantity demanded changes, leading to a new demand schedule. A movement along the demand curve occurs when there is a change in price, leading to a change in quantity demanded, while the other factors remain constant. Deflation or hyperbola formation are not terms typically used to describe changes in demand.

A baker bought flour and other ingredients for S250.00, spent S52.00 on distribution, sold the bread for S320.00. The value added by the baker.

Antwoorddetails

The value added by the baker is $90.00. To calculate the value added by the baker, we need to subtract the cost of goods sold (COGS) from the revenue. The COGS in this case includes the cost of flour and other ingredients, which is not given, but we know that the baker spent a total of $250.00 on these items. We also need to include the cost of distribution, which is $52.00. So the total COGS is $250.00 + $52.00 = $302.00. The revenue from selling the bread is $320.00. Therefore, the value added by the baker is $320.00 - $302.00 = $18.00. In other words, the baker added $18.00 of value to the raw materials and distribution costs to produce and sell the bread. This value added represents the baker's contribution to the economy and is a measure of the wealth created by the baker's business.

The ordinary partner in a partnership

Antwoorddetails

The ordinary partner in a partnership typically has unlimited liability in case of business failure. This means that they can be held personally liable for any debts or obligations of the business that are not satisfied by the assets of the partnership. This is a major disadvantage of a partnership, as it exposes the personal assets of the partners to the risk of loss in the event of business failure. While the extent of the involvement of the ordinary partner in the management of the business may vary, they are typically expected to take an active part in the management and decision-making of the partnership. As such, they cannot be said to take no active part in the management of the business. Furthermore, as a general rule, partners are jointly and severally liable for the actions of the partnership, which means that they can be sued personally on matters relating to the business. Limited liability, on the other hand, is a characteristic of some types of business entities such as limited liability companies (LLCs) and corporations.

Antwoorddetails

An advantage of the sole proprietorship over the partnership form of business organization is that it relies on the decision of one individual and does not require the consent or involvement of others. This can make decision-making more efficient and effective, and reduce the possibility of conflicts between partners. In contrast, partnerships require consensus and agreement among multiple individuals, which can be time-consuming and challenging, especially when there are disagreements. However, it is important to note that a sole proprietorship does not enjoy limited liability for debt in the event of failure, and its existence is limited by the individual owner's life span.

Antwoorddetails

The major role of multi-national companies in the petroleum industry in Nigeria is oil prospecting. These companies typically invest heavily in exploration, drilling, and production of crude oil in Nigeria, which is one of the largest oil-producing countries in Africa. The multi-national companies also play a significant role in the development of Nigeria's oil and gas infrastructure, including pipelines, storage facilities, and export terminals, which are necessary for getting the oil to international markets. While some of these companies are also involved in downstream activities such as oil marketing and refining, their primary role in Nigeria's petroleum industry is oil exploration and production.

Which of the following cannot be classified as a natural resource?

Antwoorddetails

An iron rod cannot be classified as a natural resource. A natural resource is a material or substance that occurs naturally in the environment and can be used for economic gain. Natural resources can be classified into renewable and non-renewable resources. Renewable resources are those that can be replenished over time, such as solar energy, wildlife, and forests. Non-renewable resources are those that cannot be replenished, such as minerals and fossil fuels, including gold. An iron rod is not a natural resource because it is a manufactured item made from iron, which is a natural resource. The iron has been extracted from the earth and processed to make the rod, which is then used for various purposes. So, while the raw material (iron) may be a natural resource, the finished product (the iron rod) is not.

The largest component of national income in developing countries consist of

Antwoorddetails

In developing countries, the largest component of national income is typically wages and salaries. This means that the majority of the income earned in these countries comes from the money that people make from their jobs or employment. Wages and salaries are paid to workers in exchange for their labor, and they are typically the main source of income for most people in developing countries. This income can come from a variety of sources, including working in factories, farming, providing services, or working in other industries. While profits and rent can also be important sources of income in some cases, they generally make up a smaller proportion of national income in developing countries. Profits are the earnings that businesses make after deducting their expenses, while rent is the income that comes from owning property or other assets. In summary, the largest component of national income in developing countries is typically wages and salaries, which are earned by workers in exchange for their labor.

Which of the following industries will add more value to primary products?

Antwoorddetails

The industry that adds more value to primary products is the processing industry. The processing industry takes raw materials, such as those produced by the mining industry, and turns them into finished products through various manufacturing processes. This added value comes from transforming the raw materials into something that is more useful and valuable to consumers. The service industry, on the other hand, provides services to individuals and businesses, such as consulting, financial advice, or customer support. While the service industry is important for the economy, it does not add value to primary products in the same way that the processing industry does. The construction industry involves the building of structures and infrastructure, such as buildings, roads, and bridges. While the construction industry uses materials produced by the mining industry, it does not add value to these materials in the same way that the processing industry does. In conclusion, the processing industry is the industry that adds the most value to primary products by transforming raw materials into finished goods that are more useful and valuable to consumers.

Which of the following is not emphasized in a product possibility curve?

Antwoorddetails

The concept of unemployment of labor is not emphasized in a product possibility curve. A product possibility curve is a graphical representation of the trade-off between two goods that an economy can produce, given its limited resources and technology. The curve shows the maximum combinations of the two goods that can be produced with the available resources, taking into account that some resources are better suited for producing one good over the other. The emphasis is on the scarcity of resources and the efficiency with which they are being used, not on the employment of labor.

To compare the standard of living among nations, the most widely used economic indicator is the

Antwoorddetails

To compare the standard of living among nations, the most widely used economic indicator is the real per capita income. This is a measure of the average income per person in a given country, adjusted for inflation to reflect the purchasing power of that income. It is calculated by dividing the real gross domestic product (GDP) of a country by its population, which gives a sense of the economic output per person. While per capita nominal income and real gross national income are also used as economic indicators, they do not take into account inflation or differences in the cost of living across countries, which can make them less useful for comparing living standards. Real domestic output is not as widely used as real per capita income as it does not take into account the size of the population, which is an important factor in determining the standard of living.

An example of transfer payments in national income accounting is

Antwoorddetails

Transfer payments refer to payments made by the government or other institutions to individuals or other entities, without receiving any goods or services in return. These payments are typically made for social welfare purposes or to redistribute income. An example of a transfer payment in national income accounting is unemployment allowance paid to citizens who are unemployed. The government pays these allowances to support individuals who are currently out of work and seeking employment. This payment is considered a transfer payment because the government is not receiving any goods or services in return for the funds provided. Transfer payments are not included in the calculation of GDP because they do not represent the production of goods or services. However, they are important in measuring the overall economic well-being of a society, particularly in terms of income distribution and social welfare.

Under flexible exchange rates, a deficit could be corrected by

Antwoorddetails

Under flexible exchange rates, a deficit could be corrected by the appreciation of other currencies. Flexible exchange rates are determined by market forces of supply and demand, without any government intervention. This means that the value of a country's currency can fluctuate based on changes in economic conditions and market expectations. In the case of a deficit, the demand for a country's currency will decrease, causing its value to fall relative to other currencies. This depreciation can make the country's exports cheaper and more competitive, while making imports more expensive, which can help correct the deficit. On the other hand, the appreciation of other currencies can make a country's exports more expensive and reduce demand for them, which can worsen the deficit.

Fixing the prices of agricultural products can be a problem because of the

Antwoorddetails

Fixing the prices of agricultural products can be a problem because of the unpredictable output of farmers. Agricultural output can vary due to a variety of factors including weather, pests, disease, and other unpredictable factors. This variability can make it difficult to accurately predict the supply of agricultural products and set prices accordingly. While the instability of government policies, activities of marketing boards, and the size of agricultural exports can also have an impact on the pricing of agricultural products, the unpredictable output of farmers is a primary factor that can create challenges in setting prices. Instability of government policies can create uncertainty in the market, while the activities of marketing boards can sometimes lead to distortions in supply and demand. The size of agricultural exports can also influence prices by affecting the balance of supply and demand in domestic and international markets.

Nation engage in external trade because of difference in

Antwoorddetails

Nations engage in external trade because of the differences in comparative cost, also known as comparative advantage. Comparative advantage is the ability of a country to produce goods or services at a lower opportunity cost than another country. Opportunity cost is the cost of one choice in terms of the best alternative that must be given up. In other words, it's the cost of producing one product in terms of the number of other products that could have been produced instead. For example, let's say that Country A can produce both cars and computers, but it can only produce one of them at a time. If Country A devotes all its resources to producing cars, it can produce 100,000 cars per year. If it devotes all its resources to producing computers, it can produce 50,000 computers per year. Meanwhile, Country B can produce 60,000 cars per year or 30,000 computers per year. In this case, Country A has a comparative advantage in producing cars because it has a lower opportunity cost of producing cars compared to computers. As a result, Country A can produce cars at a lower cost and sell them to Country B, which can in turn produce computers at a lower cost and sell them to Country A. This allows both countries to benefit from trade and improve their overall welfare. In summary, nations engage in external trade because of the differences in comparative cost, which allow countries to specialize in producing goods and services that they can produce more efficiently and trade with other countries for goods and services that they cannot produce efficiently. This creates mutual benefits for all countries involved.

The advantage which firms obtain directly from expanding their operations are referred to as

Antwoorddetails

The advantage which firms obtain directly from expanding their operations are referred to as "internal economies of scale." Internal economies of scale occur when a firm's average cost of production decreases as it increases the scale of its operations. This can be due to a variety of factors, such as increased specialization of labor, greater use of capital equipment, or better purchasing power for inputs. Internal economies of scale enable a firm to become more efficient and competitive as it grows, which can result in higher profits and a stronger market position. The opposite of internal economies of scale is internal diseconomies of scale, which occur when the average cost of production increases as a firm becomes too large or complex to manage efficiently.

A consumer of a single commodity is in equilibrium when

Antwoorddetails

A consumer of a single commodity is in equilibrium when they have reached a point where they are satisfied with the amount of the commodity they have purchased and consumed, and do not feel the need to buy any more or any less of it. This equilibrium can be achieved in different ways, but one common way is when the marginal utility, or the additional satisfaction gained from consuming one more unit of the commodity, is equal to the price paid for that unit. In other words, the consumer is willing to pay the price because they feel they are getting enough satisfaction from the additional unit. At this point, the consumer has no incentive to buy more of the commodity, because the marginal utility would be lower than the price, and they would feel like they are overpaying for the satisfaction gained. Conversely, if the price were to decrease, the marginal utility would be higher than the price, and the consumer may feel like they are getting a good deal and may want to purchase more of the commodity. Ultimately, the consumer is in equilibrium when they have found a balance between the satisfaction gained from the commodity and the price paid for it.

The price mechanism 

Antwoorddetails

The price mechanism is a system in an economy where the prices of goods and services are determined by the forces of supply and demand. This mechanism is responsible for regulating the balance between what consumers want to buy and what producers want to sell. As the demand for a particular item increases, the price of the item will rise, causing producers to increase supply to meet the demand. On the other hand, if the demand decreases, the price will fall, and producers will decrease their supply. In this way, the price mechanism helps allocate scarce resources by ensuring that the goods and services that are in high demand are produced and distributed more, while those that are not in high demand are produced and distributed less. In conclusion, the price mechanism does all of the above - regulates supply and demand, rations the consumers, rewards the producers, and allocates scarce resources - to ensure an efficient and effective allocation of resources in an economy.

In the long-run, a firm must shut down if its average revenue is

Antwoorddetails

In the long-run, a firm should shut down if its average revenue is less than its average cost. This is because, in the long-run, all costs are considered variable, meaning the firm can adjust its production and input levels. If the firm continues to operate despite having average revenue less than average cost, it will continue to incur losses. To understand this concept, it's essential to know what the average revenue and average cost mean. Average revenue is the total revenue earned by a firm divided by the quantity of output produced. On the other hand, average cost is the total cost incurred by a firm divided by the quantity of output produced. The average cost can further be divided into two categories: average variable cost and average fixed cost. The average variable cost is the cost that varies with the level of output, such as labor and raw material costs. In contrast, the average fixed cost is the cost that remains constant regardless of the level of output, such as rent and salaries. So, in the long-run, a firm must shut down if its average revenue is less than its average cost because it means that the firm is not generating enough revenue to cover all its variable and fixed costs. By shutting down, the firm can avoid further losses and redirect its resources elsewhere. On the other hand, if the firm's average revenue is greater than its average cost, it can continue to operate and earn profits.

If the Central Bank increases its bank rate

Antwoorddetails

If the Central Bank increases its bank rate, it means that it has increased the interest rate at which commercial banks can borrow money from the Central Bank. This, in turn, makes it more expensive for commercial banks to borrow money, which can have several effects on the economy. Firstly, since it is more expensive for banks to borrow money, they may become more cautious about lending money to their customers. This means that customers may find it more difficult to obtain loans or credit from banks, and the amount of borrowing may decrease. So, is not correct. Secondly, if banks find it more expensive to borrow money, they may also try to increase the interest rates they charge on loans and mortgages to maintain their profits. This could make borrowing more expensive for customers, and the interest charges by banks may rise rather than fall. So, is not correct. Thirdly, if the cost of borrowing money for commercial banks increases, they may not want to borrow as much money, which could reduce the supply of money in the economy. So, is correct. Lastly, an increase in the Central Bank's bank rate may not cause many banks to shut down their operations. However, some smaller banks or financial institutions that heavily rely on borrowing may struggle to stay afloat. So, is not correct. In conclusion, an increase in the Central Bank's bank rate can reduce the supply of money in the economy and increase the cost of borrowing for banks, which could result in higher interest rates for customers.
