Answer Details

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.

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.

When the supply of a commodity increases, it means that there is more of that commodity available in the market than before. This increase in supply causes the market to shift, leading to a change in the equilibrium price and quantity of that commodity. As the supply of the commodity increases, sellers will want to sell more of the commodity, but buyers may not want to buy as much at the higher price. This creates a surplus, where there is more supply than demand, causing the price to decrease. As the price decreases, buyers are more willing to buy the commodity, and sellers may reduce the amount they are willing to sell, until the market reaches a new equilibrium. This new equilibrium will have a lower price and a higher quantity bought and sold than before the increase in supply. Therefore, the correct answer is: a decrease in the equilibrium price and an increase in the equilibrium quantity bought and sold.

A retailer is distinguished by the nature of its sales, which is in units. Retailers sell products in small quantities directly to consumers for their personal or household use. They purchase products from wholesalers or manufacturers and sell them to the end-users at a markup. This type of retailing typically involves a physical store where customers can browse and purchase products, but it can also include online retailing. The focus of retailing is on selling individual units of products to the consumer, rather than selling in bulk to other businesses.

Answer Details

Restrictive monetary policy is designed to overcome inflation. Inflation is when the overall price level in an economy is rising, and the value of money is decreasing. The central bank can use restrictive monetary policy to reduce the amount of money in circulation and decrease aggregate demand, which will in turn help to curb inflation. For example, the central bank may increase interest rates, which makes borrowing money more expensive and reduces consumer spending. It may also sell government bonds, which reduces the amount of money available in the banking system. This type of policy is called restrictive because it restricts or slows down the growth of the economy, which helps to control inflation.

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.

Answer Details

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.

Answer Details

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 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.

Answer Details

If the wage rate is less than the average revenue product (ARP), the firms would be earning a profit. The ARP is the amount of revenue generated by one unit of labor and is typically greater than the wage rate. If the firm is paying its workers less than the amount of revenue they generate, the firm will have extra revenue left over, which is a profit. So, in this situation, the firm would either be earning a normal profit or a super normal profit, depending on the size of the gap between the wage rate and the ARP. A normal profit is the minimum level of profit necessary for a firm to stay in business, while a super normal profit is a profit that is higher than the normal profit.

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.

Answer Details

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.

In the short-run, a monopoly can make abnormal profit. Abnormal profit is a profit that is higher than the normal profit a company would make in a competitive market. This is because a monopoly has market power, meaning it has control over the price of its product and can set it higher than the market price, leading to higher profits. However, it's important to note that this situation is only temporary and in the long-run, competition and other factors can drive down prices and eliminate the abnormal profit.

The main disadvantage of a one-man business is that the proprietor is personally liable for the firm's debts. This means that if the business is unable to pay its debts, the proprietor's personal assets, such as their savings, property, or other valuables, can be used to settle the debt. This can put the proprietor's personal financial stability at risk and may discourage them from taking on certain business ventures or expanding the business.

All of the options listed - I, II, III, and IV - can contribute to changes in supply. Technological advances in an industry can increase the efficiency of production and lower costs, leading to an increase in supply. Changes in labor costs, such as an increase in wages, can make production more expensive, leading to a decrease in supply. Changes in the source of supply, such as a new supplier entering the market or a current supplier becoming unavailable, can also impact supply. Finally, changes in levels of taxation, such as an increase in taxes on production, can make production more expensive and lead to a decrease in supply. Therefore, all four options can impact changes in supply.

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.

The basic and essential economic problems in a community are related to choice and scarcity. Scarcity refers to the limited availability of resources in any given community. These resources can include natural resources, such as land, water, and minerals, as well as human-made resources, such as factories, machines, and tools. Because these resources are limited, there is never enough of them to satisfy everyone's wants and needs. This scarcity means that individuals, businesses, and governments must make choices about how to allocate these resources in the most efficient way possible. This requires making trade-offs and decisions about what goods and services to produce, how to produce them, and who should receive them. , Freedom, and Politics, are not directly related to the basic and essential economic problems of choice and scarcity. Social class, may be related to economic problems, but is not a fundamental concept in economics.

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.

"Good government planning" is not a cause of unemployment. Unemployment refers to the situation where individuals who are actively seeking employment are unable to find work. The causes of unemployment can be complex and multi-faceted, but typically include factors such as a lack of available jobs, poor education and lack of relevant skills, and corruption. "Good government planning" is not a direct cause of unemployment, but it can have an indirect effect by helping to create a favorable economic environment that supports job growth and job creation. For example, good government planning can help to attract businesses to an area, provide funding for education and training programs, and reduce corruption, all of which can help to reduce unemployment over time.

Industrialization is the process of transforming an economy from primarily agriculture and handicrafts to one based on the manufacturing of goods. This process usually involves the development of new technologies, the growth of factories, and an increase in the production of goods. The goal of industrialization is to increase economic growth and improve the standard of living for a society. During industrialization, the production of goods becomes more efficient and large-scale, and people move from rural areas to cities to work in factories. In short, industrialization is the transformation of a society from traditional ways of making things to more modern and efficient methods of production.

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.

Answer Details

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.

The lands that belong to the community as a whole, rather than to individuals, are referred to as "communal land." Communal land is a type of property that is owned and managed collectively by a community, rather than by individual landowners. In many cases, communal land is held by a community as a shared resource that is used for various purposes, such as farming, grazing, or hunting. Communal land can be found in various forms, including indigenous lands, public lands, and lands held in common by small communities. These lands are often governed by customary or traditional rules and practices that have been developed over time by the community members. The use and management of communal land can be beneficial for communities that depend on the land for their livelihoods, as it allows for collective decision-making and sharing of resources. However, it can also present challenges when there are disputes over land use or when outside interests seek to exploit the resources on communal land.

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.

Answer Details

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.

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.
