Let capital formation = CF, Production = P, C = consumption. Then CF =_______

Antwoorddetails

Capital formation (CF) is equal to P minus C, where P is production and C is consumption. Capital formation refers to the process of creating new capital goods, such as factories, machines, and infrastructure, which are used to produce goods and services. This process requires investment in new capital goods and is therefore reflected as a reduction in consumption. So, CF = P - C, where P is the total amount of goods and services produced and C is the amount consumed by households, businesses, and government. This equation shows that the amount of new capital being formed is equal to the difference between what is produced and what is consumed. In simpler terms, capital formation is the amount of investment made in the economy to increase its productive capacity and support future economic growth.

If two commodities are unrelated, a change in the price of one will____________

Antwoorddetails

If two commodities are unrelated, a change in the price of one will have no effect on the quantity demanded of the other. This is because unrelated commodities are not substitutes for each other, so a change in the price of one will not affect the demand for the other. For example, if the price of apples increases, it will not affect the demand for bananas, since apples and bananas are not substitutes for each other. Similarly, if the price of bananas decreases, it will not affect the demand for apples. This is because the demand for each commodity is determined by its own factors, such as income, tastes, and preferences, and not by the price of other unrelated commodities.

Let the quantity demanded in units of a particular commodity be represented as Qd = 80 - 2P, find the quantity demanded when P = ₦3.

Antwoorddetails

The quantity demanded (Qd) of a commodity is related to its price (P) through the equation Qd = 80 - 2P. So, if we know the price of the commodity, we can use this equation to find the quantity demanded. In this case, the price is given as ₦3. So, we can plug in this value of price into the equation to find the quantity demanded: Qd = 80 - 2P Qd = 80 - 2 * 3 Qd = 80 - 6 Qd = 74 Therefore, the quantity demanded when the price is ₦3 is 74 units.

The average curve and the marginal curve are U-shaped in the short-run and flatter in the long-run due to________

Antwoorddetails

The reason why the average curve and the marginal curve are U-shaped in the short-run and flatter in the long-run is due to economies of scale. Economies of scale refer to the cost advantages that firms experience as they increase their production output. In the short-run, firms are often operating at less than their optimal capacity and therefore may experience diseconomies of scale as they increase output, which leads to higher average costs and a U-shaped average curve. Meanwhile, the marginal cost curve intersects the average cost curve at its minimum point, which is why it is also U-shaped in the short-run. However, in the long-run, firms have more time to adjust their inputs and can increase the scale of their operations. As they do so, they can experience economies of scale, which lead to lower average costs and a flatter average curve. This means that the marginal cost curve intersects the average cost curve at a lower point than in the short-run, making it flatter. Overall, this illustrates how economies of scale can affect a firm's production costs and how this can be reflected in the shape of the average and marginal cost curves.

Whatever form an economic system may take, choice is essential for members of the community because resources are__________

Antwoorddetails

Scarce. This means that there is not enough of a certain resource to meet the demand or needs of everyone in the community. As a result, choices have to be made about how to allocate these limited resources among different individuals, groups, or uses. When resources are scarce, it is important to make decisions about their use in the most efficient and effective way possible.

One of these is not a way by which government encourage industrialization?

Antwoorddetails

Low productivity and inefficiency is not a way by which government encourages industrialization. In fact, it is the opposite. Encouraging industrialization means creating a favorable environment for businesses to grow and increase productivity. Low productivity and inefficiency hinder the growth of industries, making it difficult for the government to encourage industrialization. On the other hand, protection of infant industries, establishment of Nigeria Enterprises Promotion Decree, and establishment of higher institutions are ways by which the government can encourage industrialization. Protection of infant industries involves offering support and protection to new and growing businesses to help them establish and grow. The establishment of Nigeria Enterprises Promotion Decree provides support and incentives for local businesses to grow and expand. The establishment of higher institutions provides a well-educated workforce, which is essential for industrial growth and development.

The money market equilibrium is defined as_________

Antwoorddetails

The money market equilibrium is defined as when the demand and supply of money are equal. In other words, the amount of money people want to hold (demand) is equal to the amount of money available (supply). Think of the money market as a marketplace where people buy and sell money. Just like any other market, when there is high demand for a product, its price (in this case, the interest rate) will increase. When there is low demand, the price (interest rate) will decrease. In the money market, the interest rate is a measure of the cost of borrowing money. If there is a high demand for money, people are willing to pay a higher interest rate to borrow it. This results in an increase in the interest rate. On the other hand, if there is low demand for money, people are not willing to pay a high interest rate, and the interest rate decreases. When the demand and supply of money are equal, the interest rate will be at the level where the quantity of money that people want to hold is equal to the amount of money available. This is the money market equilibrium.

An example of a vertical combination is the merger of_________

Antwoorddetails

Effective demand for a commodity is desire for that commodity backed by_______

Antwoorddetails

Effective demand for a commodity is the desire or want for that commodity backed by the ability and willingness to pay for it. This means that a person not only wants the commodity, but also has the means to purchase it and is willing to part with their money in exchange for it. For example, if someone wants to buy a new car but does not have the money to pay for it, their desire for the car is not effective demand. Similarly, if someone has the money but is not interested in buying a car, their willingness to pay is not effective demand. Effective demand requires both the desire for the commodity and the ability and willingness to pay for it. It is the combination of these two factors that drives the demand for goods and services in the economy.

An economy system that uses what is regarded as the "Market mechanism" is called_______

Antwoorddetails

Capitalism is an economic system that uses the market mechanism. In a capitalist economy, individuals and businesses own and operate the means of production, and the prices of goods and services are determined by supply and demand in the marketplace. In simple terms, this means that people are free to produce and sell whatever they want, and consumers are free to buy whatever they want, at prices that are determined by the market. This creates an economy that is driven by competition and innovation, and is often associated with growth and prosperity. It is important to note that capitalism can take on different forms, ranging from a more laissez-faire approach with minimal government intervention, to a more regulated form with a larger role for the government in managing the economy.

In the case of highly or close complementary goods, the indifference curve is_______

Antwoorddetails

External economies arises essentially from__________

Antwoorddetails

External economies arise essentially from the localization of industry. External economies occur when an industry or group of firms in a specific geographical area experience benefits beyond what they could achieve individually. This can include access to specialized suppliers, a skilled labor force, and a larger market for their products or services. Localization of industry refers to the concentration of firms in a specific area. This can create a cluster of related industries and suppliers, allowing for easier collaboration, lower transportation costs, and increased efficiency. Government policies, such as subsidies or tax incentives, may encourage the localization of industries, but they do not create external economies themselves. Similarly, a firm's individual policies and the free transferability of shares do not create external economies as they are focused on the internal operations of the firm. Overall, external economies are a result of the benefits that arise from firms operating in close proximity to each other in a specific geographic location, which can lead to increased efficiency and productivity for all firms involved.

Consider the diagram below which shows a demand curve (d).

Total expenditure on a commodity is represented by the area TUVW. Consumer's surplus is represented by__________

Antwoorddetails

Consumer's surplus is represented by the area above the demand curve and below the market price. In the diagram, this would be the area represented by VWX. Consumer's surplus measures the difference between the amount that consumers are willing to pay for a good and the amount they actually pay. In the diagram, consumers are willing to pay more for the good up to the market price, represented by the height of the demand curve. The area VWX represents the amount by which they are benefiting from the market, as they are paying less than they would be willing to pay. So, the answer to the question is the area VWX represents consumer's surplus.

The following are measures of location except________

Antwoorddetails

The measure of location that is not a measure of location is "Range". A measure of location gives us an idea of where most of the values in a data set are concentrated. Arithmetic mean, Harmonic mean, and Geometric mean are all measures of location that give us a single value to represent the center of the data set. For example, the arithmetic mean is the sum of all the values divided by the number of values. The harmonic mean is the reciprocal of the arithmetic mean of the reciprocals of the data values. The geometric mean is the nth root of the product of n values. On the other hand, the range is a measure of spread, which gives us an idea of how spread out the values in a data set are. The range is simply the difference between the largest and smallest values in a data set.

ECOWAS was formed for the purpose of________

Antwoorddetails

ECOWAS, or the Economic Community of West African States, was formed for the purpose of promoting co-operation and integration among its member countries. This means that the organization was created to help the countries work together and coordinate their efforts in areas such as trade, politics, and development. The goal of ECOWAS is to promote economic and social progress in the region and improve the lives of the people living in West Africa.

In a perfect competition, the market price is determined by_______

Antwoorddetails

In a perfect competition, the market price is determined by the market supply and demand junctions. This means that the price is set by the intersection of the supply of goods and services offered by producers and the demand for those goods and services by consumers. When there is a high demand for a good or service, the price will go up, and when there is a low demand, the price will go down. This is because producers will raise their prices when there is high demand in order to make more profit, and they will lower their prices when there is low demand to try to sell more goods. On the other hand, consumers will be willing to pay more for a good or service when there is high demand and they will be less willing to pay when there is low demand. The market price is a result of the negotiation between producers and consumers, and it reflects the balance between supply and demand in the market.

Antwoorddetails

Which of the following matters may account for changes in demand?

I - changes in consumer preferences

II - changes in real income

III - changes in distribution of incomes

IV - changes in levels of taxation

Antwoorddetails

Changes in demand can be influenced by various factors. Among them, changes in consumer preferences, real income, distribution of incomes, and levels of taxation can all affect the quantity of a good or service that consumers are willing and able to buy at a given price. I. Changes in consumer preferences refer to shifts in the tastes and preferences of consumers. For example, if people start to prefer healthier food options, the demand for fruits and vegetables may increase while the demand for processed foods may decrease. II. Changes in real income can also impact demand. If people's real income increases, they may be able to afford more goods and services, which can lead to an increase in demand for those products. Conversely, if real income decreases, consumers may cut back on their spending, leading to a decrease in demand. III. Changes in the distribution of incomes can also affect demand. If the distribution of incomes becomes more unequal, with some people becoming much richer and others becoming much poorer, this can impact the demand for certain products. For example, if the rich become richer, they may be more willing to purchase luxury goods, leading to an increase in demand for those products. On the other hand, if the poor become poorer, they may not be able to afford certain goods, leading to a decrease in demand. IV. Changes in levels of taxation can impact demand by affecting the disposable income of consumers. If taxes increase, consumers may have less disposable income, leading to a decrease in demand for certain goods and services. Conversely, if taxes decrease, consumers may have more disposable income, leading to an increase in demand for certain products. Therefore, the answer is: I, II, III, IV, since all four factors can account for changes in demand.

Whether a monopolist is able to increase his revenue by restricting his output depends on the shape of the_________

Antwoorddetails

The shape of the demand curve determines whether a monopolist is able to increase their revenue by restricting output. A monopolist is the only seller in the market and has some control over the price of the good or service they provide. If the demand for their product is high, they can increase the price, and if they restrict the quantity of the product they supply, the price will go up even more. The demand curve shows the relationship between the price of a good and the quantity of it that consumers are willing and able to buy. If the demand curve is downward sloping, it means that as the price of the good increases, the quantity demanded decreases. This is because consumers will switch to cheaper alternatives when the price of the good goes up. So, if the monopolist restricts their output, the price will go up and they will make more profit as long as the demand curve remains downward sloping. However, if the demand curve becomes perfectly inelastic, meaning that the quantity demanded does not change with the price, then the monopolist will not be able to increase their revenue by restricting output. Therefore, in simple terms, the shape of the demand curve determines whether a monopolist can increase their revenue by restricting output.

Economics is a social science concerned with the proper use and______

Antwoorddetails

Economics is a social science concerned with the proper use and allocation of resources for growth. Economics is the study of how society uses its limited resources to satisfy its unlimited wants and needs. It is concerned with how individuals, businesses, and governments make choices about how to use resources to produce goods and services, and how these goods and services are distributed among the members of society. The proper use and allocation of resources are essential for economic growth, which is the increase in the production and consumption of goods and services over time. This growth is achieved through the efficient use of resources to create more goods and services, which can then be distributed to meet the needs of society. Economics helps us to understand how resources are allocated and used in different economies and how these decisions affect the overall well-being of individuals and societies.

The demand curve facing the monopolist in the foreign market is__________

Antwoorddetails

The arithmetic mean of 5, 8, 10, 15, 24 and 28 is_______

Antwoorddetails

To find the arithmetic mean of a set of numbers, you need to add up all the numbers and divide the sum by the total number of numbers. In this case, we have six numbers, so we need to add them up and divide by 6. Adding up the numbers, we get: 5 + 8 + 10 + 15 + 24 + 28 = 90 Then, we divide the sum by the total number of numbers: 90 / 6 = 15 Therefore, the arithmetic mean of 5, 8, 10, 15, 24 and 28 is 15.

Which of the following persons is engaged in "Secondary Production"?

I - a bricklayer

II - an automobile assembly-line worker

III - an accountant

IV - a cinema projectionist

Antwoorddetails

Secondary production refers to the process of transforming raw materials into finished goods, typically in a factory setting. Out of the four options, only one involves transforming raw materials into finished goods in a factory setting, and that is option II, an automobile assembly-line worker. A bricklayer (option I) works in construction and is not involved in transforming raw materials into finished goods in a factory setting. An accountant (option III) works in the service sector and is not involved in producing goods. A cinema projectionist (option IV) is also not involved in producing goods but rather in providing a service. Therefore, the answer is option II, an automobile assembly-line worker.

If the demand for a commodity is perfectly elastic, the incidence of a tax on that commodity will be, other things being equal, entirely on the_______

Antwoorddetails

If the demand for a commodity is perfectly elastic, it means that even a small change in price will cause a significant change in the quantity demanded. In other words, consumers are very sensitive to changes in price, and if the price increases, they will simply buy another substitute product that is cheaper. Now, if a tax is imposed on this commodity, it will cause the price of the commodity to increase. Since the demand is perfectly elastic, consumers will not be willing to pay the higher price and will switch to substitute products. As a result, the entire incidence of the tax falls on the seller or producer of the commodity. This is because the higher price caused by the tax will result in a decrease in the quantity demanded, and the producer will have to reduce the price in order to sell the product. Therefore, the producer bears the entire burden of the tax. In summary, if the demand for a commodity is perfectly elastic, the incidence of a tax on that commodity will be entirely on the seller or producer, as consumers are very sensitive to price changes and will switch to substitute products if the price increases.

A supply curve slopes upwards from the left to the right indicating__________

Antwoorddetails

A supply curve that slopes upwards from left to right indicates a positive slope. This means that as the price of a good or service increases, the quantity supplied by suppliers also increases. In other words, producers are willing to supply more of a good or service at higher prices. To understand why this is the case, think about it from the perspective of a supplier. If the price of a good or service goes up, it becomes more profitable for suppliers to produce and sell that good or service. As a result, suppliers are incentivized to increase their production in order to take advantage of the higher prices and earn more profits. This is why the quantity supplied by suppliers tends to increase as the price of a good or service increases. It's important to note that this explanation applies to the long run. In the short run, supply may be relatively fixed and a supply curve may be upward sloping or even backward sloping, indicating that the quantity supplied doesn't change much in response to changes in price. However, over the long run, suppliers have more time to adjust their production levels and the supply curve typically slopes upward.

The determination of wages in a labour market depends on the_______

Antwoorddetails

The determination of wages in a labor market depends on the interaction between the demand for and supply of labor. In simple terms, employers demand labor to produce goods and services, while workers supply their labor to earn wages. The wage rate is then determined by the equilibrium point where the demand for labor meets the supply of labor in the market. When there is a high demand for labor and a low supply, wages tend to increase because employers are competing for a limited number of workers. On the other hand, when there is a low demand for labor and a high supply, wages tend to decrease because there are more workers than jobs available. Other factors such as government policies, economic conditions, and the skills and qualifications of workers can also influence the wage rate, but the main determinant is the interaction between the demand for and supply of labor in the market.

The basic principle underlying location of industry is the tendency for production of a commodity to be located on the basis of______

Antwoorddetails

The basic principle underlying the location of industry is the tendency for production of a commodity to be located on the basis of "relative costs and benefits." The location of industry is determined by a variety of factors such as access to raw materials, labor supply, transportation, energy, and infrastructure. However, the primary factor is the cost and benefit analysis of each potential location. Industries tend to locate where the benefits of the location outweigh the costs. For example, an industry that requires large quantities of water may locate near a river or lake where water is abundant and cheap. An industry that produces heavy goods may locate near a port or railhead to reduce transportation costs. An industry that produces high-value products may locate near a skilled workforce or a research and development center to take advantage of the availability of talent. In general, industries seek to minimize their costs and maximize their benefits by locating in areas that provide the best combination of factors. This is why certain industries tend to be concentrated in particular regions or countries where the relative costs and benefits of production are most favorable.

If AC and MC are represented on a graph, the MC curve will cut the AC curve_______

Antwoorddetails

The MC (marginal cost) curve will cut the AC (average cost) curve at the minimum point on the AC curve. This is because the minimum point on the AC curve represents the lowest average cost of production, and the MC curve intersecting the AC curve at this point indicates that the marginal cost of producing one more unit is equal to the average cost. In other words, at the minimum point on the AC curve, any further increase in production would lead to an increase in the average cost.

A commodity is defined as normal when its demand changes in the same direction as______

Antwoorddetails

A commodity is defined as normal when its demand changes in the same direction as income. This means that as income increases, demand for the commodity will also increase, and as income decreases, demand for the commodity will decrease. Normal goods are those goods for which demand increases as income increases, and decreases as income decreases. For example, as people's incomes increase, they may choose to buy more luxury items such as expensive cars, jewelry, or designer clothing, which would be considered normal goods. On the other hand, as people's incomes decrease, they may choose to cut back on these purchases and switch to more budget-friendly options, causing demand for normal goods to decrease.

An economy in which the whole income is not consumed is referred to as______

Antwoorddetails

The last link in the channel of distribution is____________

Antwoorddetails

The last link in the channel of distribution is the Consumer. The channel of distribution refers to the path that a product takes from the producer to the final customer. The producer creates the product, and it is then sold to a wholesaler, who sells it to a retailer, and finally, the retailer sells it to the consumer. The consumer is the end user of the product and is the last link in the chain of distribution. In other words, the consumer is the person who ultimately buys the product and uses it for their own purposes. The channel of distribution is important because it helps to ensure that the product reaches the end user in a timely and efficient manner.

As indifference curve shows equal level of satisfaction at all points, An isoquant shows equal level of_________

Antwoorddetails

An isoquant shows equal level of output. An isoquant is a curve that represents all the possible combinations of inputs (such as labor and capital) that can produce the same level of output for a particular product or service. In other words, it represents all the different ways to produce the same amount of output using different combinations of inputs. So, all points on an isoquant represent the same level of output, and this level of output gives us the same satisfaction or usefulness. As we move along the isoquant, we can produce the same output using different combinations of inputs, but the level of output remains constant. In simple terms, an isoquant is a line that shows the different combinations of inputs that can produce the same level of output.

The purchasing power of money depends upon the__________

Antwoorddetails

The purchasing power of money depends upon the "price level". Price level refers to the general level of prices for goods and services in an economy. When the price level increases, the purchasing power of money decreases because it can buy fewer goods and services. Conversely, when the price level decreases, the purchasing power of money increases because it can buy more goods and services. For example, if a cup of coffee costs $2 and the price level remains the same, then $10 can buy 5 cups of coffee. However, if the price of coffee increases to $3, then the purchasing power of $10 decreases and can now only buy 3 and 1/3 cups of coffee. So, the purchasing power of money depends on the price level, because the price level determines how much goods and services money can buy.
