A firm that closes down will still incur

Maelezo ya Majibu

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.

The price mechanism 

Maelezo ya Majibu

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.

A price floor is usually fixed

Maelezo ya Majibu

A price floor is typically set above the equilibrium price, and it creates a surplus of goods or services. When the price is set above the equilibrium level, it causes suppliers to offer more products than buyers are willing to purchase at that higher price. This leads to a surplus, where there are more goods available than there are buyers willing to buy them. Therefore, a price floor usually causes surpluses, and not shortages.

The major role of multi-national companies in the petroleum industry in Nigeria is

Maelezo ya Majibu

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.

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

Maelezo ya Majibu

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.

Under a floating exchange rate regime, the determinant of the exchange rate is

Maelezo ya Majibu

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.

The largest component of national income in developing countries consist of

Maelezo ya Majibu

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.

Producers operating in a free market economy are more efficient as a result of

Maelezo ya Majibu

Producers operating in a free market economy are more efficient as a result of the existence of competition. In a free market, businesses compete with each other for customers by offering better quality products, lower prices, or both. This competition forces producers to be efficient and innovative in order to remain competitive and attract customers. As a result, businesses are motivated to increase productivity, reduce waste, and improve their products and services to meet customer needs. The competition also leads to more choices for consumers and lower prices, as businesses strive to provide the best value for money. In contrast, if there were no competition, businesses would have less incentive to improve their operations, resulting in lower efficiency and higher prices for consumers.

Economic goods are termed scarce goods when they are

Maelezo ya Majibu

Economic goods are termed scarce goods when they are not available in sufficient quantity to satisfy all wants for them. In other words, when there is a limited supply of a good or resource, but a potentially unlimited demand for it, that good is considered to be scarce. This concept is fundamental to economics because it helps to explain why goods have value and why individuals and societies must make choices about how to allocate scarce resources.

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?

Maelezo ya Majibu

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.

Which of the following factors is not a cause of diminishing returns?

Maelezo ya Majibu

The factor that is not a cause of diminishing returns is "Technological innovations". Diminishing returns refers to the decrease in marginal output or production as more units of a variable input (such as labor or capital) are added to a fixed amount of other inputs (such as land or machinery). This occurs because the fixed inputs become increasingly scarce relative to the variable inputs, which can lead to inefficiencies and reduced productivity. The other three factors listed - an increase in variable inputs, land fragmentation, and constant technology - can all contribute to diminishing returns. For example, adding more workers to a fixed amount of land may lead to overcrowding and reduced productivity (land fragmentation). Similarly, if technology remains constant while more inputs are added, the additional inputs may not be fully utilized and may even become redundant. In contrast, technological innovations can actually help to overcome diminishing returns by allowing for more efficient use of inputs and increasing productivity. New technologies can improve the efficiency of production processes, reduce waste, and create new products or services, all of which can lead to increased output and economic growth.

Maelezo ya Majibu

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.

The major role of multi-national companies in the petroleum industry in Nigeria is

Maelezo ya Majibu

The major role of multinational companies in the petroleum industry in Nigeria is oil prospecting. Multinational companies, also known as International Oil Companies (IOCs), play a significant role in the exploration and production of oil and gas in Nigeria. These companies invest heavily in the exploration of new oil fields, as well as the development and production of existing fields. While some IOCs are also involved in oil marketing and refining, their primary role in Nigeria is oil prospecting. The IOCs in Nigeria include major companies such as Shell, ExxonMobil, Chevron, and Total.

If W stands for wages/salaries, P for profits, R for interest and Z for rent on land and real estate, then national income is

Maelezo ya Majibu

If W stands for wages/salaries, P for profits, R for interest, and Z for rent on land and real estate, then the national income is given by:

W + P + R + Z

This is because national income is the total amount of income earned by individuals and firms within a country's borders, and it includes all four components of W, P, R, and Z.

Wages and salaries are earned by employees, profits are earned by business owners, interest is earned by lenders, and rent is earned by landlords. When we add up all of these components, we get the total national income.

Therefore, "W+P+R+Z," is the correct answer.

An example of transfer payments in national income accounting is

Maelezo ya Majibu

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.

A downward sloping demand curve means that

Maelezo ya Majibu

A downward sloping demand curve means that as the price of a good decreases, the quantity demanded of that good increases. In other words, there is an inverse relationship between the price of a good and the quantity of that good demanded by consumers. This is the fundamental law of demand in economics.

As the price of a good decreases, consumers are more willing and able to purchase it, which leads to a higher quantity demanded. Conversely, as the price of a good increases, consumers are less willing and able to purchase it, which leads to a lower quantity demanded.

Therefore, the correct answer is - price must be lowered to sell more of the good. Total revenue may increase or decrease as the price changes depending on the magnitude of the change in price and quantity demanded.

A consumer of a single commodity is in equilibrium when

Maelezo ya Majibu

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.

Maelezo ya Majibu

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.

Positive check as envisaged by Thomas Malthus can be prevented if

Maelezo ya Majibu

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.

Maelezo ya Majibu

The International Bank for Reconstruction and Development (IBRD) is a specialized agency of the United Nations that provides loans, technical assistance, and other services to developing countries. Out of the options provided, the IBRD does not reduce tariffs among its members. Its main focus is on granting long-term loans to member countries for development projects, providing technical expertise to help those countries implement those projects successfully, and developing human resources in those countries. Tariff reduction is not one of its main functions.

In the long run, all production factors are

Maelezo ya Majibu

In the long run, all production factors are "variable." This means that in the long run, a firm can adjust all of its production inputs, including labor, capital, and technology, to change the scale of its operations. In the short run, some inputs may be fixed, such as the size of the factory, which can only be changed in the long run. But in the long run, all inputs can be varied to optimize production and increase efficiency. The ability to adjust all inputs in the long run is what distinguishes the long run from the short run in the theory of production.

A situation in which all inputs are doubled and output also doubles is known as

Maelezo ya Majibu

The situation in which all inputs are doubled and the output also doubles is known as "constant returns to scale." This means that if a firm increases all of its inputs by a certain proportion, the output will also increase by the same proportion. In other words, the production function exhibits constant returns to scale if increasing all inputs by a constant factor results in an output increase by the same constant factor.

The point x inside the ppc indicate?

Maelezo ya Majibu

The point x inside the PPC (Production Possibility Curve) indicates that some of the resources in the economy are currently idle or not being fully utilized. This means that the economy is not producing at its maximum potential, and there is room for further growth and development. The PPC represents the different combinations of goods and services that an economy can produce given its limited resources and technology. The curve shows the maximum output that can be produced with the available resources and technology at a given point in time. Any point inside the curve represents a level of production that is below the maximum potential output, indicating that some resources are not being used to their full capacity. Therefore, if the economy is currently operating at a point inside the PPC, it has the potential to increase its production of goods and services by putting its idle resources to work. This could be achieved through measures such as increasing investment, improving technology, or providing more education and training to the workforce.

A made obstacle to economic development is

Maelezo ya Majibu

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.

Economics problems arise in all societies because

Maelezo ya Majibu

Economics problems arise in all societies because of the fundamental concept of scarcity. Scarcity means that the resources available to society are limited, while the wants and needs of individuals are virtually unlimited. This leads to a situation where individuals, businesses, and governments have to make choices about how to allocate scarce resources in the most efficient and effective way possible. For example, a society may want to provide free healthcare to all its citizens, but it may not have the resources to do so. Alternatively, a business may want to produce more products, but it may not have the resources to expand its production line. These are just two examples of the countless economic choices that are made every day. Mismanagement of resources by leaders, lack of planning, inadequate supply of resources, and underutilization of economists are some of the factors that can exacerbate economic problems in a society. However, the underlying cause of economic problems is the scarcity of resources, which requires individuals and institutions to make difficult choices about how to allocate those resources.

Cooperative societies are formed mainly to

Maelezo ya Majibu

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.

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

Maelezo ya Majibu

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.

Under flexible exchange rates, a deficit could be corrected by

Maelezo ya Majibu

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.

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?

Maelezo ya Majibu

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 effect of changes in the condition of demand on a demand schedule with the price constant is a

Maelezo ya Majibu

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.

In perfectly elastic supply, the supply curve

Maelezo ya Majibu

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.

Scale of preference shows

Maelezo ya Majibu

The scale of preference refers to a list of a consumer's wants or desires arranged in order of importance or priority. It shows the consumer's preferences or choices among different options. The scale of preference is subjective and varies from person to person. For instance, if a person is given the choice to buy a new smartphone, a new pair of shoes, or a ticket to a concert, they may rank these options in order of priority. If they value communication more than entertainment, they may choose the smartphone as their top priority. Conversely, if they value entertainment more than communication, they may choose the concert ticket. Thus, the scale of preference is a way to understand how consumers make choices based on their preferences and priorities, and it helps in predicting their behavior in the market.

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.

Maelezo ya Majibu

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.

A minimum price legislation is also called

Maelezo ya Majibu

A minimum price legislation is also called a price floor. A price floor is a type of price control set by the government that sets a minimum price that must be paid for a particular good or service. The government typically sets a price floor in order to help support the producers of the good or service by ensuring they receive a certain level of income. For example, if the government sets a minimum price for agricultural goods, such as wheat or milk, it can help support farmers by ensuring that they receive a fair price for their products. A price floor is usually set above the equilibrium price of the good or service in question, which means that it can create a surplus of supply. This surplus can result in a number of economic issues, such as a buildup of inventory or a decrease in demand, which can lead to further government intervention or market adjustments. Overall, price floors and other types of price controls can be controversial, as they can have both positive and negative effects on producers, consumers, and the overall economy.

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

Maelezo ya Majibu

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.
