Awọn alaye Idahun

The principle that specifies that the amount, when, and how to pay tax should be made known to the taxpayer is known as the Principle of Certainty. This principle ensures that taxpayers have a clear understanding of their tax obligations, which includes knowing the amount of tax they owe, the deadline for payment, and the method of payment.
The Principle of Certainty is important because it promotes transparency and accountability in the tax system. By providing clear and specific information to taxpayers, it enables them to accurately calculate and plan for their tax obligations. This helps to avoid confusion or misunderstandings between the taxpayer and the tax authorities.
Furthermore, the Principle of Certainty also ensures fairness and consistency in the tax system. By clearly stating the rules and requirements, it ensures that all taxpayers are treated equally and that there is no ambiguity or room for arbitrary decisions in the tax assessment process.
Overall, the Principle of Certainty provides a solid foundation for the relationship between taxpayers and tax authorities. It establishes clear expectations, promotes compliance, and adds credibility to the tax system.

Agriculture accounts for about 60% of the

Awọn alaye Idahun

Agriculture accounts for about 60% of the active labour force in West Africa. This is because a large portion of the population in West Africa is engaged in farming and other agricultural activities for their livelihood. The other options are incorrect as agriculture does not account for 60% of the arable land, service sector activities, or the commodity market in West Africa.

All of the following describes conditions necessary for existence of a perfect market EXCEPT

Awọn alaye Idahun

A perfect market is a theoretical concept that represents an idealized scenario where certain conditions are met. In this market, there is an equilibrium between supply and demand, and no single buyer or seller has the power to influence prices. In order for a perfect market to exist, there are several conditions that need to be met. These conditions include: - **Lack of homogeneity of goods**: In a perfect market, goods are assumed to be identical and indistinguishable from one another. This means that there are no variations in quality, features, or brand identity. Buyers are indifferent to which seller they purchase from since the goods are the same. - **Perfect knowledge**: Another crucial condition is that all buyers and sellers in the market have access to complete and accurate information. This means they know the current market prices, availability of goods, and all relevant factors influencing the buying and selling decisions. No hidden or asymmetric information exists that could give an advantage to any market participant. - **Large buyers and sellers**: A perfect market assumes that there are a significant number of buyers and sellers in the market. This ensures that no single buyer or seller has enough market power to influence prices or control the market conditions. Each participant is a price taker, meaning they accept the prevailing market price and cannot change it on their own. - **Portability of goods**: The final condition for a perfect market is the ease with which goods can be transported from one place to another. This means that there are no significant barriers to trade, such as transportation costs, tariffs, or restrictions. Goods can freely move between buyers and sellers, allowing for efficient market operations. Now, looking at the given options, we need to identify the one that does NOT describe a condition necessary for the existence of a perfect market. And that would be **"lack of homogeneity of goods"**. In a perfect market, goods are assumed to be identical and indistinguishable. This means that there are no variations in quality or features. Homogeneity is a vital characteristic of a perfect market, so the lack of it would hinder the existence of a perfect market. In summary, the conditions required for a perfect market are: perfect knowledge, large buyers and sellers, and portability of goods. While homogeneity of goods is a necessary condition for a perfect market, it is not described in the options as a condition necessary for the existence of a perfect market.

The economies of West African Countries depend majorly on

Awọn alaye Idahun

The economies of West African countries primarily depend on primary products.
Primary products refer to raw materials or natural resources that are extracted directly from the earth or sea. These resources typically include agricultural products such as crops, livestock, and fisheries, as well as minerals and natural resources like oil, gas, and minerals.
West African countries, like many developing nations, tend to have economies that are heavily reliant on these primary products. This reliance is due to a combination of factors such as the abundance of natural resources in the region and historical patterns of economic development.
Agriculture plays a significant role in the economies of West African countries, with a large percentage of the population engaged in farming activities. These countries export a variety of agricultural products, including cocoa, coffee, palm oil, cotton, and timber. These exports generate significant revenue and contribute to the overall economic growth of these nations.
Additionally, West Africa is rich in mineral resources such as gold, diamonds, bauxite, and iron ore. The extraction and export of these minerals also contribute to the economic development of these countries.
While some West African countries have started to diversify their economies and develop secondary and tertiary sectors, the primary sector remains a vital component of their economies. However, it is important for these countries to also focus on diversification and value addition to their primary products to reduce their vulnerability to fluctuations in global commodity prices and achieve sustainable growth.

The short run can be defined as the period of time during which at least one of the firm's inputs is fixed. In other words, it is a time frame in which the firm cannot easily or quickly adjust all of its inputs. This means that some resources, such as the size of a factory or the number of employees, cannot be changed in the short run.
During the short run, firms can only adjust their production levels by varying the amount of variable inputs, such as raw materials or utilities. The fixed input, which remains constant in this period, imposes limitations on the firm's ability to increase or decrease its output. This constraint on adjusting all inputs is what distinguishes the short run from the long run, where all inputs can be varied.
It is important to note that the length of the short run can vary depending on the industry and the specific circumstances of the firm. For some businesses, the short run may be a few months, while for others it could be several years. However, what remains consistent is that during the short run, the firm is restricted in its ability to modify certain inputs, which can impact its production and overall performance.

If commodities X and Y are substitute, their cross elasticity of demand will be

Awọn alaye Idahun

If commodities X and Y are substitutes, the cross elasticity of demand between them will be positive.
Cross elasticity of demand measures how the quantity demanded of one commodity changes in response to a change in the price of another commodity. When two commodities are substitutes, they serve similar purposes and are considered as alternatives to each other. For example, if the price of commodity X increases, some consumers may switch to commodity Y as a substitute, causing an increase in the quantity demanded of commodity Y.
The positive cross elasticity of demand reflects this relationship. It means that an increase in the price of commodity X will lead to an increase in the demand for commodity Y, and vice versa. On the other hand, if the cross elasticity of demand were negative, it would indicate that the two commodities are complements, meaning that they are used together and a change in the price of one would result in an opposite change in the demand for the other.
Therefore, in the case of substitute commodities, the cross elasticity of demand will be positive.

40 men were employed in a farm, and they produced an average of 30 tonnes of cassava per person. Calculate the total product.

Awọn alaye Idahun

To calculate the total product of cassava, we need to multiply the average production per person by the number of people.
In this scenario, we know that there were 40 men employed in the farm, and each person produced an average of 30 tonnes of cassava.
So, to find the total product, we need to multiply 40 by 30.
40 x 30 = 1200
Therefore, the total product of cassava is 1,200 tonnes.

Which of the following Age group belongs to active Labour force?

Awọn alaye Idahun

The age group that belongs to the active labor force is the **18 - 64 years** category. This age range is generally considered to be the working-age population, as it encompasses individuals who are old enough to work and have not yet reached the age of retirement. People in this age group are typically in their prime working years, where they have the physical ability and the necessary skills and knowledge to actively participate in the labor market. They are often seeking employment, working in various industries or sectors, and contributing to the economic growth and development of their country. It is important to note that the specific age range considered as the working-age population may vary slightly across different countries or regions. However, in most cases, it generally falls within the **18 - 64 years** age bracket. On the other hand, the other age groups mentioned in the options are not typically considered as part of the active labor force: - The **0 - 17 years** age group consists of individuals who are below the legal working age and are typically attending school or dependent on others for their livelihood. - The **15 - 25 years** age group partially overlaps with the working-age population, but it includes individuals who may still be in school or pursuing higher education. While some individuals within this age range may be actively seeking employment or working part-time, they are generally not considered as the core active labor force. - The **65 years and above** age group represents individuals who have reached the retirement age or are eligible for retirement benefits. While some individuals in this age range may continue to work, either out of choice or due to financial circumstances, they are not considered as the primary active labor force. In summary, the **18 - 64 years** age group is the one that belongs to the active labor force, consisting of individuals who are in their prime working years and actively participating in the labor market.

The type of unemployment that occurs when an individual cannot find job as a result of obsolete skill is

Awọn alaye Idahun

The type of unemployment that occurs when an individual cannot find a job as a result of obsolete skills is known as Structural unemployment.

Structural unemployment happens when there is a mismatch between the skills that job seekers possess and the skills required for available jobs in the market. In this case, individuals may no longer be qualified for the jobs that are available due to changes in technology, market conditions, or shifts in the economy.

For example, let's say there is a rapid advancement in technology that makes certain job skills obsolete. Workers who had those skills may struggle to find employment because companies are now looking for individuals with more up-to-date skills.

This type of unemployment is different from cyclical unemployment, which is caused by fluctuations in the business cycle, or seasonal unemployment, which occurs due to seasonal variations in demand for certain jobs. Frictional unemployment, on the other hand, refers to the temporary unemployment that occurs when individuals are transitioning between jobs or entering the workforce for the first time.

To sum up, structural unemployment is the type of unemployment that arises when an individual cannot find a job because their skills are no longer in demand.

A persistence rise in the prices of inputs will lead to

Awọn alaye Idahun

A persistence rise in the prices of inputs, such as raw materials or labor, can lead to **cost push inflation**. Cost push inflation occurs when the increased costs of production for firms are passed on to consumers in the form of higher prices for goods and services. This can happen when the prices of inputs used in production rise over a sustained period. When input costs increase, businesses often have two options: absorb the increased costs and accept lower profit margins, or pass on the higher costs to consumers by raising prices. If firms choose to raise prices, it can lead to a general increase in the overall price level in the economy. Here's a simple example to help illustrate this concept: Let's say there is a town where the main industry is manufacturing shoes. The cost of leather, which is a key input in shoe production, starts to rise due to factors like high demand or scarcity. In response, shoe manufacturers have to pay more for leather, and this increases their production costs. To maintain their profit margins, the manufacturers decide to increase the prices of shoes they sell to retailers. Now, if the retailers decide to pass on the higher costs to the consumers, the prices of shoes will increase. This can create a ripple effect throughout the economy because consumers will have to spend more money on shoes, reducing their purchasing power for other goods and services. As a result, the overall price level in the economy increases, and this is what we call cost push inflation. It is important to note that cost push inflation is different from demand pull inflation. Demand pull inflation occurs when there is an increase in aggregate demand, leading to an excess of demand over supply. In contrast, cost push inflation is driven by increased production costs. Hyperinflation, on the other hand, is an extreme form of inflation characterized by an uncontrollable increase in prices. It is typically caused by factors like rapid money supply growth or loss of confidence in the currency. Stagflation refers to a situation where there is a combination of high inflation and high unemployment, typically accompanied by low economic growth. This can occur when an economy experiences a supply-side shock, such as a significant increase in the prices of key inputs. In summary, a persistence rise in the prices of inputs can lead to cost push inflation, as firms pass on the increased costs to consumers by raising prices.

Institutions serving as links between surplus and deficit units can be identified as

Awọn alaye Idahun

Financial intermediaries serve as links between surplus and deficit units in an economy. These intermediaries include banks, credit unions, and other financial institutions. When there is surplus money in the economy, individuals and businesses deposit the excess funds with financial intermediaries. These intermediaries then pool these funds together and make them available to deficit units, such as individuals or businesses in need of loans or financing. Financial intermediaries play a crucial role in the economy by efficiently allocating funds from surplus units to deficit units. They match the needs of borrowers with the resources of savers, helping to facilitate economic growth and development. Tax officers and pension offices, on the other hand, do not serve as direct links between surplus and deficit units. Tax officers collect taxes for the government, while pension offices manage pension funds for retired individuals. Although these entities may indirectly impact the allocation of funds in the economy, their primary roles are different from that of financial intermediaries. Acceptance houses are also not direct links between surplus and deficit units. Acceptance houses provide short-term financing through the purchase of bills of exchange. While they play a role in facilitating trade between businesses, their function is more specific and limited compared to the broader role of financial intermediaries. In summary, financial intermediaries such as banks and credit unions serve as the primary links between surplus and deficit units in an economy. They gather surplus funds from savers and make them available to borrowers, thereby promoting the efficient allocation of resources.

Economists refer to private goods as

Awọn alaye Idahun

Private goods are referred to as rivalrous and excludable by economists. Let me explain what this means in a simple and comprehensive way.
When a good is rivalrous, it means that one person's use or consumption of the good diminishes its availability for others. For example, if you eat an orange, there is now one less orange for someone else to consume. The consumption of the orange by one person reduces the availability of the orange for others.
On the other hand, when a good is excludable, it means that it is possible to prevent someone from using or consuming that good if they do not pay for it. For instance, if you go to a movie theater and buy a ticket, you are allowed entry to watch the movie. However, if you do not buy a ticket, you will be excluded from watching the movie.
Private goods possess both of these characteristics. They are rivalrous because one person's use or consumption of the good reduces its availability for others. For example, if you buy a car, only you can use it at any given time, and someone else cannot simultaneously use it. Private goods are also excludable because it is possible to prevent others from using or consuming the good if they do not pay for it. For instance, if you purchase a book, you have exclusive access to read it unless you choose to share it with someone.
In summary, private goods are referred to as rivalrous and excludable because their consumption diminishes their availability for others, and it is possible to exclude others from using or consuming them if they do not pay for them.

Awọn alaye Idahun

The demand for a good is price inelastic if the price elasticity is less than one. Price elasticity measures how responsive the quantity demanded of a good is to a change in its price. If the price elasticity is less than one, it means that the quantity demanded is not very responsive to changes in price. In other words, a change in price will have a relatively small impact on the quantity demanded. Even if the price increases or decreases, people will still buy a similar amount of the good. This can happen when the good is a necessity or when there are limited substitutes available. For example, if the price of water increases, people will still need to buy a similar amount because water is essential for survival. Similarly, if the price of a specific medication increases, people with no alternative options will still purchase it regardless of the price. Therefore, when the price elasticity is less than one, we say that the demand for the good is price inelastic.

Given the table demonstrating the law of diminishing marginal utility below, what is the value of X?

Awọn alaye Idahun

The Marginal Utility is the additional satisfaction a consumer gains from consuming one more unit of a good or service. It can be calculated by subtracting the total utility of the previous consumption from the total utility of the current consumption. In this case, the total utility of consuming 2 oranges is 16 and the total utility of consuming 1 orange is 9. Therefore, the marginal utility (X) of the second orange is 16 - 9 = 7.

The diagram above represents the production possibility curve.
The production possibility curve shows the different combinations of goods and services that can be produced given the available resources and technology.
On the curve, each point represents a specific combination of goods and services that can be produced. Points on the curve are considered efficient because all available resources are fully utilized. Points inside the curve represent inefficient production because resources are not fully utilized. Points outside the curve represent combinations that are currently unattainable given the available resources and technology.
In summary, the production possibility curve helps us understand the trade-offs and limitations in production based on available resources and technology. It is a visual representation of the production possibilities in an economy.

The law of supply states that, other things being constant, as price increases

Awọn alaye Idahun

The law of supply states that, other things being constant, as price increases, the quantity supplied also increases. Basically, when the price of a good or service goes up, suppliers have an incentive to produce and sell more of that item. This is because they can earn more profit by selling at the higher price. So, as the price rises, suppliers are motivated to increase their production and offer more of the product to the market. On the other hand, when the price of a good or service decreases, suppliers have less motivation to produce and sell it. This is because they can earn less profit or even incur losses at the lower price. As a result, they will reduce the quantity supplied. In summary, the law of supply tells us that there is a direct relationship between price and quantity supplied. When the price increases, suppliers respond by increasing the quantity they are willing to supply to the market. Conversely, when the price decreases, the quantity supplied decreases.

Real cost is

Which of the following would not be a reason for a government to impose a quota on imports?

Awọn alaye Idahun

A quota on imports is a restriction imposed by a government on the quantity of goods that can be imported into a country. It is typically done to protect domestic industries and promote economic growth.

Out of the given options, a government imposing a quota on imports would not be done to decrease tax revenue. In fact, the purpose of implementing import quotas is quite the opposite – to increase tax revenue by protecting domestic industries and promoting their growth.

Let's understand this further:

1. To support strategic industry: One of the main reasons governments impose import quotas is to protect and support domestic industries that are considered strategically important for the country's economy. By limiting imports, the government aims to give domestic industries an advantage by reducing competition from foreign firms.

2. To prevent dumping: Dumping refers to the practice of selling goods in another country at prices lower than their production costs or market value. This undermines domestic industries and poses a threat to their survival. By imposing import quotas, the government can control the influx of dumped products and protect domestic industries from unfair competition.

3. To decrease tax revenue: This option is incorrect because imposing import quotas does not aim to decrease tax revenue. When imports are restricted, domestic industries have less competition, which allows them to charge higher prices. As a result, the government can collect more tax revenue from these higher-priced goods, thus increasing its overall revenue.

4. Employment opportunity: Another reason governments may impose import quotas is to create employment opportunities. By limiting imports, domestic industries can expand their production and hire more workers to meet the local demand. This helps in reducing unemployment and improving the overall economic conditions of the country.

In conclusion, the correct answer is that a government would not impose a quota on imports to decrease tax revenue. Import quotas are intended to protect strategic industries, prevent dumping, and create employment opportunities, while also increasing tax revenue.

Awọn alaye Idahun

A tariff is a tax that is imposed on imported goods. It is a financial charge that a government puts on goods that are being brought into the country. The purpose of a tariff is to protect domestic industries and businesses from competition from imported goods. By placing a tax on imported goods, it becomes more expensive for consumers to buy those goods, making them less appealing compared to domestic alternatives. This gives domestic industries a competitive advantage and helps support local businesses and jobs. So, the correct answer is imported goods.

The rate of output per worker (or group of workers) per unit time is called

Awọn alaye Idahun

The correct answer is labour productivity.
Labour productivity refers to the rate at which output is produced by a worker or a group of workers in a given amount of time. It measures how efficiently and effectively workers are using their skills, time, and resources to produce goods or services.
To understand this concept, let's imagine a scenario where we have two workers producing bicycles. Worker A is able to produce 5 complete bicycles in one hour, while Worker B can only produce 3 complete bicycles in the same amount of time.
In this case, Worker A has a higher labour productivity because they are able to produce more output (bicycles) per unit of time (one hour) compared to Worker B.
Labour productivity is an essential measure for companies and economies because it directly impacts their profitability and competitiveness. Higher labour productivity means that more goods or services can be produced using the same amount of resources or in less time. This leads to lower costs per unit and can result in higher profits or the ability to lower prices for customers.
In summary, labour productivity is a measure of how efficiently workers are producing goods or services and is calculated by dividing the total output by the number of workers or the amount of time it took to produce that output.

Awọn alaye Idahun

When a generalization is made based on observed facts, it is called inductive reasoning. Inductive reasoning involves drawing conclusions from specific instances or examples to come up with a general statement or theory. This means that we observe a pattern or trend from the evidence we have and then make a generalization or inference based on that pattern. Inductive reasoning is different from deductive reasoning, which involves starting with a general statement or theory and then using it to predict or explain specific instances. In inductive reasoning, we start with specific observations and use them to make a broader generalization. It is important to note that while inductive reasoning can often lead to accurate conclusions, it is not always guaranteed to be correct. However, it is a common and useful method used in many fields such as science, sociology, and psychology.

Calculate the equilibrium level of national income (Y) where Y = C + I + G; C = 100 + 0.75Y; I = 50; G = 200

Awọn alaye Idahun

To calculate the equilibrium level of national income (Y), we start with the equation Y = C + I + G. In this equation, C represents consumption spending, I represents investment spending, and G represents government spending. Now, let's substitute the given values into the equation: C = 100 + 0.75Y I = 50 G = 200 Substituting these values, we get: Y = (100 + 0.75Y) + 50 + 200 To solve for Y, we need to simplify the equation: Y = 100 + 0.75Y + 50 + 200 Combining like terms, we have: Y = 350 + 0.75Y Next, we can solve for Y by isolating it on one side of the equation. To do this, we can subtract 0.75Y from both sides: Y - 0.75Y = 350 Simplifying further, we have: 0.25Y = 350 Finally, we can solve for Y by dividing both sides of the equation by 0.25: Y = 350 / 0.25 Calculating this, we find: Y = 1400 So, the equilibrium level of national income (Y) is 1400.

The quantity of commodity a consumer is willing and able to buy at a particular time is called

Awọn alaye Idahun

The quantity of a commodity that a consumer is willing and able to buy at a particular time is called demand.
Demand refers to the consumer's desire or willingness to purchase a specific product or service at a given price and at a given time. It represents the customer's intent to buy and the amount they are willing to buy at various price levels.
It is important to note that demand is not just about the desire for a particular item, but also the consumer's ability to pay for it. For example, someone may wish or desire to buy a luxury car, but if they do not have the financial means to afford it, their demand for that car is limited.
In summary, demand is the quantity of a commodity that a consumer is both willing and able to buy at a given time, reflecting their desire for the product and their ability to pay for it.
