Detalhes da Resposta

The firm is said to be experiencing diseconomies of scale if the cost of production continues to increase as its output rises. Diseconomies of scale occur when the firm becomes too large, and the increased complexity and coordination costs of managing a large organization outweigh the benefits of increased production. This can result in a decrease in efficiency, productivity, and profitability for the firm.

Detalhes da Resposta

The major disadvantage of a capitalist economy is that it worsens income inequality among the citizens. In a capitalist system, the means of production and distribution of goods and services are privately owned and operated for profit, leading to a concentration of wealth and power in the hands of a small group of people who own the most productive resources. This results in a situation where the rich get richer, while the poor get poorer, and there is a growing gap between the incomes and living standards of the wealthy and the less well-off members of society. This can create social unrest and political instability, as well as limit opportunities for social mobility and economic growth.

Detalhes da Resposta

One possible factor that limits the extent of growth of a firm is the unwillingness to share ownership and control. When a firm is controlled by a single owner or a small group of owners who are not willing to share ownership or decision-making power, it can limit the firm's ability to raise capital, make strategic partnerships, or expand into new markets. In contrast, allowing outside investors or partners to have a stake in the company can provide the firm with access to more resources, expertise, and new opportunities for growth.

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

Detalhes da Resposta

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.

Economic goods are termed scarce when they are?

Detalhes da Resposta

Economic goods are termed scarce when they are "not available in sufficient quantities to satisfy all wants for them." Scarce resources are those that have a limited supply relative to the demand for them. This scarcity means that choices must be made about how the resources are allocated, and that not all wants or needs can be fully satisfied. The concept of scarcity is fundamental to the study of economics, as it is the basis for understanding the concepts of opportunity cost, trade-offs, and efficiency.

Detalhes da Resposta

The demand for labor is an example of "derived demand." Derived demand refers to the demand for a factor of production or a good that arises as a result of the demand for another good or service. In the case of labor, it is not demanded for its own sake but rather because it is needed to produce goods and services that consumers demand. The demand for labor is therefore derived from the demand for the goods and services that labor helps to produce.

Detalhes da Resposta

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.

A firm that closes down will still incur

Detalhes da Resposta

Even if a firm closes down, it will still incur some fixed costs. Fixed costs are expenses that must be paid regardless of the level of production or whether the business is operating or not. These costs include things like rent, insurance, salaries of employees on long-term contracts, and equipment leases. Variable costs, on the other hand, are expenses that vary depending on the level of production or business activity. For example, the cost of materials or labor directly related to producing goods or services. If the firm closes down, it will not incur variable costs because it will not be producing any goods or services. Total cost is the sum of fixed and variable costs, so if the firm is not producing anything, the total cost will be equal to the fixed cost. Marginal cost is the cost of producing one additional unit of a good or service. If the firm is closed down, there is no production, so there is no marginal cost.

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

Detalhes da Resposta

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.

Fiscal policy measures imply a change in

Detalhes da Resposta

Fiscal policy measures imply a change in government revenue and expenditure to regulate an economy. Fiscal policy is a tool used by governments to influence the economy by adjusting their spending levels and tax rates. This can be done by either increasing or decreasing government spending and taxes in order to achieve specific economic goals, such as controlling inflation, boosting employment, or promoting economic growth. For example, if the government wants to stimulate economic growth, it may increase its spending on infrastructure projects or offer tax incentives to businesses. Conversely, if the government wants to control inflation, it may decrease government spending and increase taxes to reduce the amount of money circulating in the economy. Therefore, fiscal policy measures involve making changes to both government revenue and expenditure in order to achieve specific economic objectives.

Detalhes da Resposta

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.

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.

If the Central Bank increases its bank rate

Detalhes da Resposta

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.

Palm oil and palm kernel are in

Detalhes da Resposta

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.

The main objective of marketing boards is to stabilize the incomes of cash crop farmers. Marketing boards help to regulate the supply and demand of cash crops, ensuring stable prices and incomes for farmers. They also provide support services to farmers, such as warehousing facilities and education on pricing, to help them sell their crops more effectively. While marketing boards may generate revenue for the government, their primary focus is on supporting and protecting the livelihoods of farmers.

Detalhes da Resposta

The privatization and commercialization of public enterprises in Nigeria is necessitated by their operational inefficiency. Public enterprises in Nigeria, like in many other countries, have often been criticized for poor management, corruption, and inefficiency, which have resulted in heavy financial losses for the government. Privatization and commercialization are seen as a way to introduce more competition, increase efficiency, and reduce the financial burden on the government. While the IMF and the World Bank have encouraged privatization in many countries as a condition for receiving loans, in Nigeria, the privatization and commercialization policies were largely driven by domestic factors, including the need to improve the performance of public enterprises.

Holding money to take care of contingencies is

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.

The concept described in the given scenario is called "double coincidence of wants." It refers to the situation where two parties have goods or services that the other party desires and are willing to exchange, and both parties are able to meet each other's wants at the same time. In the example, the housewife wants tomatoes, and she has meat that she can offer in exchange. However, she can only trade with someone who has tomatoes and also wants meat. The double coincidence of wants occurs when both parties have what the other wants, and both are willing and able to trade. This concept is important in understanding how bartering works, which is an exchange of goods and services without the use of money.

Positive check as envisaged by Thomas Malthus can be prevented if

Detalhes da Resposta

Thomas Malthus proposed the concept of a positive check, which refers to a population control mechanism in which natural disasters, disease, and famine limit the population growth. However, positive checks are not desirable as they lead to high levels of human suffering. To prevent positive checks, it is necessary to implement measures that help to control population growth while maintaining the well-being of individuals. One way to achieve this is by reducing the death rate through improved healthcare, better nutrition, and access to safe water and sanitation. Another approach is to promote moral restraint, which involves encouraging individuals to delay marriage and childbearing until they are economically stable and can provide for their children. Additionally, building more hospitals can help to improve access to healthcare, which can contribute to reducing the death rate and improving overall health outcomes. Natural calamities, on the other hand, can lead to positive checks, and as such, they are not a desirable solution for preventing population growth. Instead, efforts should focus on implementing sustainable population control measures that promote economic development, education, and access to healthcare, while also protecting the environment.

If the government imposes a minimum price on a commodity

Detalhes da Resposta

If the government imposes a minimum price on a commodity, it means that sellers cannot sell the commodity for a price lower than the minimum price set by the government. This is done to ensure that the producers of the commodity are getting a fair price for their goods. When a minimum price is set, it may result in excess supply (market surplus) of the commodity, as producers may be incentivized to produce more of the commodity at the higher price. However, the surplus can be reduced if the government buys the excess supply or if producers reduce their production. In the short-run, the market may be cleared, which means that all of the available supply of the commodity is sold at the minimum price set by the government. However, in the long-run, excess demand may occur as the minimum price may discourage buyers from purchasing the commodity. Therefore, government regulation may still be needed to ensure that the market operates efficiently, even with the minimum price in place.

If the quantity demanded of a commodity increases from 20 units to 30 units when there is an increase in price from $4.00 to $5.00, the elasticity of demand is

Detalhes da Resposta

The elasticity of demand measures the responsiveness of the quantity demanded of a commodity to a change in its price. In this case, when the price of the commodity increased from $4.00 to $5.00, the quantity demanded increased from 20 units to 30 units. To calculate the elasticity of demand, we use the following formula: Elasticity of demand = (percent change in quantity demanded) / (percent change in price) First, let's find the percent change in quantity demanded: (30 units - 20 units) / 20 units = 0.50 or 50% Next, let's find the percent change in price: (5.00 - 4.00) / 4.00 = 0.25 or 25% Finally, let's plug in the values into the formula: Elasticity of demand = 0.50 / 0.25 = 2.00 So, the elasticity of demand in this case is 2.00. This means that a 1% increase in price leads to a 2% decrease in the quantity demanded.

A disadvantage of a joint-stock company is

Detalhes da Resposta

A disadvantage of a joint-stock company is the potential for loss of controlling interest. In a joint-stock company, ownership is divided into shares, which can be bought and sold by individual shareholders. If a large number of shares are sold to other individuals or entities, it can dilute the ownership and control of the original shareholders, making it more difficult for them to have a significant say in the decision-making process. Limited liability is actually an advantage of a joint-stock company, as it protects shareholders from personal financial liability beyond their investment in the company. Continuity is also an advantage of a joint-stock company, as it can continue to exist even if shareholders come and go or if one or more shareholders die. Unlimited liability, on the other hand, is a disadvantage of a sole proprietorship or partnership, where the owner or partners can be held personally liable for the debts and obligations of the business.

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?

Detalhes da Resposta

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.

What happens when the central bank increases the bank rate in an economy

Detalhes da Resposta

When the central bank increases the bank rate, it becomes more expensive for banks to borrow money from the central bank. This in turn causes interest rates on loans and mortgages offered by commercial banks to increase as well. As a result, people and businesses are less likely to take out loans, because they have to pay more in interest. So, borrowing is discouraged. On the other hand, banks are able to charge more for loans, so they can increase their profits. However, this increase in interest rates can also lead to a decrease in spending, which can slow down economic growth.

Detalhes da Resposta

Under a floating exchange rate regime, the determinant of the exchange rate is "demand for and supply of foreign goods." In a floating exchange rate system, the exchange rate between two currencies is determined by the market forces of supply and demand. Factors such as interest rates, inflation rates, and trade flows can influence the demand for and supply of currencies, which in turn can affect the exchange rate. Unlike fixed exchange rate systems, where the exchange rate is determined by government policy, in a floating exchange rate system, the exchange rate can fluctuate based on market conditions.

In a pie chart, the population of a city is represented by 45. If the country has a population of 10 million people, then the city's population is?

Detalhes da Resposta

To solve this problem, we need to first understand what a pie chart is and how it works. A pie chart is a circular graph that is divided into sectors, with each sector representing a proportion of the whole. The size of each sector is proportional to the quantity it represents, so we can use it to determine the percentage or fraction of the whole that each quantity represents.

In this case, the city's population is represented by 45 degrees of the pie chart. If we assume that the pie chart represents the entire country's population, which is 10 million people, then the fraction of the country's population represented by the city is:

45 degrees / 360 degrees = 1/8

This means that the city's population is 1/8 of the entire country's population. To find out the actual population of the city, we can multiply the fraction by the total population:

(1/8) x 10 million = 1.25 million

Therefore, the correct answer is 1.25 million.

In the event of bankruptcy, owners of joint-stock companies lose

Detalhes da Resposta

In the event of bankruptcy, owners of joint-stock companies (also known as shareholders) typically only lose the capital they have invested in the company. They do not lose their private properties or personal assets. When an individual buys shares in a joint-stock company, they become a partial owner of the company. As a shareholder, they are entitled to receive a share of the company's profits in the form of dividends. However, if the company goes bankrupt and cannot meet its financial obligations, the shareholders may lose the value of their investment, meaning the shares they hold in the company become worthless. Therefore, shareholders may lose the capital they invested in the company, but they are not responsible for any additional debts or liabilities the company may have. Shareholders are only liable to lose the value of their shares and do not have to worry about losing their personal assets or private properties.

Detalhes da Resposta

A major obstacle to economic development is low farm productivity. Agriculture is a significant sector in many developing countries, and low farm productivity can have a significant impact on economic growth and development. Low productivity in agriculture can result from a range of factors, including inadequate access to credit, poor infrastructure, low-quality inputs, and limited knowledge of modern farming techniques. This can limit the production of food and raw materials for industrial processes, resulting in higher prices, reduced exports, and lower economic growth. Increasing farm productivity is often a key focus of development programs and policies aimed at promoting economic development in developing countries.

In perfectly elastic supply, the supply curve is a horizontal line. This means that the quantity of a good that a supplier is willing to sell is not affected by changes in the price of the good. The supplier will sell any quantity of the good at the market price, no matter how high or low it is. In other words, the supply is perfectly responsive to changes in the price, so the supply curve is flat.

Detalhes da Resposta

Cooperative societies are primarily formed to promote and maintain the welfare of their members. This means that the members of a cooperative society come together to work towards achieving common goals that benefit everyone in the society. Cooperative societies are usually formed by a group of individuals who share a common interest, such as farming, housing, or credit. By working together, members can access resources that they may not have been able to on their own, such as bulk purchasing of materials, access to credit, or sharing of knowledge and skills. In a cooperative society, the focus is not on maximizing profits for individual members, but rather on achieving benefits that are shared by the entire group. By working together, members can create a sustainable and mutually beneficial organization that can help to address the needs of the community. Therefore, the main purpose of cooperative societies is to promote the welfare of members by providing a platform for collective action and collaboration.

Detalhes da Resposta

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.

An example of commodity money is silver. Commodity money is a physical object that has intrinsic value in addition to its value as a medium of exchange. Historically, commodities such as gold and silver have been used as a form of money because they are scarce and have inherent value. For example, silver is used not only as money, but also for jewelry, silverware, and other industrial applications. In this way, its value is based on its usefulness in addition to its value as a medium of exchange. In contrast, modern forms of money, such as currency notes, mobile money, and cheques, are not commodities in and of themselves but represent a claim on goods and services.
