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.

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.

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 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.

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.

The term M33 comprises M11 together with deposits on deposit accounts held by banks and discount houses. In economics, M33 refers to a measure of the money supply in an economy, which includes all of the components of M11 (i.e. notes and coins in circulation, and deposits held by banks and building societies), as well as the deposits held by discount houses. Discount houses are financial institutions that specialize in providing short-term loans to other financial institutions, such as banks. Because they hold deposits from these other financial institutions, their deposits are included in measures of the money supply like M33. , banks only, and banks, discount houses, and stock exchanges, are not complete answers because they do not include the role of discount houses in M33. discount houses only, is not a complete answer because it excludes the role of banks in M33. banks and discount houses, is the correct and complete answer.

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.

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 demand for labor is a "derived demand". This means that the demand for labor is not a direct demand for labor itself, but rather it is derived from the demand for goods and services that labor can produce. In other words, businesses hire workers because they need them to produce the goods and services that they sell. For example, if a business sells pizzas, it will need workers to make the pizzas, deliver the pizzas, and serve the customers. The demand for labor in this case is derived from the demand for pizzas. If the demand for pizzas increases, the demand for labor to produce and deliver the pizzas will also increase. Therefore, the demand for labor is closely tied to the demand for the goods and services that labor produces, and it is derived from that demand.

The oil boom between 1970-1980 caused the oil sector to become the main source of government revenue. This is because during this time period, the demand for oil was high and the price of oil was high, which led to an increase in profits for oil companies and the countries that produced oil. As a result, the government received a significant portion of its revenue from the oil sector, which made it the main source of government funding. This allowed the government to fund various projects and initiatives, and also had a significant impact on the economy.

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.

The use of government income and expenditure instrument to regulate the economy is called fiscal policy. Fiscal policy is a tool used by the government to influence the economy by changing the level and composition of government spending and taxation. The main aim of fiscal policy is to achieve macroeconomic objectives, such as controlling inflation, promoting economic growth and stability, and reducing unemployment. When the government increases its spending and/or reduces taxes, it injects more money into the economy, which can increase consumer spending and business investment. This can help to stimulate economic growth, create jobs, and increase aggregate demand. On the other hand, when the government reduces its spending and/or increases taxes, it takes money out of the economy, which can help to cool down an overheating economy and reduce inflation. In summary, fiscal policy involves using government income (taxation) and expenditure (spending) to influence the economy and achieve macroeconomic objectives.

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.

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.

An oil spill is the release of a liquid petroleum hydrocarbon into the environment. This can occur in a variety of ways, such as from an oil tanker that leaks or a pipeline that ruptures. The oil can contaminate the water and harm wildlife, as well as damage the natural environment and disrupt human activities such as fishing and tourism. It is important to take measures to prevent and clean up oil spills to minimize their impact on the environment and local communities.

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.

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.

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.

"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.

An import quota is a permit that allows an importer to bring a certain quantity of foreign goods into a country. It is a government-imposed limit on the quantity of a certain good that can be imported into a country during a specific period of time. The purpose of an import quota is to protect domestic producers and limit the amount of foreign competition in the domestic market. The government sets the quota to regulate the flow of goods into the country and to ensure that domestic producers are not overwhelmed by foreign competition.

The method of adding up all the rewards of the factors of production in national income is known as the "income approach." The income approach calculates national income by summing up all the income received by individuals and firms in the economy. This includes wages, salaries, interest, rent, and profits earned by the factors of production, such as labor, capital, and land. The idea behind this approach is that the total income generated in an economy is equal to the total amount spent on consumption and investment, and this spending creates the demand for goods and services produced in the economy. This method provides a comprehensive picture of the total income generated in the economy and is useful in understanding the distribution of income among different groups in the economy and the sources of economic growth.

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.

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.

Adam Smith's theory of value stated that the value of a commodity depends on the amount of labour expended on its production. Smith believed that in a market economy, the value of a good or service is determined by the amount of work required to produce it. According to his theory, the more time and effort that goes into making a product, the more valuable it becomes. This idea is known as the "labour theory of value." In simple terms, the value of a product is determined by the effort and time put into making it. The more effort and time required, the more valuable the product is considered to be. This theory is considered to be one of the foundations of classical economics and is still widely studied and discussed today.

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.

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.

The determination of price by bargaining between buyers and sellers is called Haggling or Higgling. This is a process where buyers and sellers negotiate the price of a product or service, typically in an informal setting. The buyer wants to pay as little as possible, while the seller wants to get as much as they can. They both compromise and agree on a price that is acceptable to both parties. Haggling is common in open-air markets, street vendors, and in some cultures it's a part of the normal purchasing process. In this process, the buyer and the seller communicate and exchange information about the value of the product or service, and how much each is willing to pay or receive. The price is ultimately determined through a give-and-take negotiation, and both parties must agree on the final price for the transaction to occur.

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.
