Awọn alaye Idahun

The production process described in the question, where the marginal physical product of the variable factor increases as more units of it are added to a fixed factor, is referred to as increasing returns to the variable factor. In this case, the variable factor is becoming increasingly productive as more units of it are added, which results in an increase in the marginal physical product. Increasing returns to scale, on the other hand, refer to the situation where an increase in all factors of production leads to a more than proportionate increase in output. Constant returns to the variable factor occur when increasing the variable factor by a certain percentage leads to a proportional increase in output. Finally, external economies of scale refer to the cost advantages that a firm experiences as a result of factors outside of its control, such as the growth of an industry or the development of infrastructure.

Awọn alaye Idahun

Holding money to take care of contingencies is a precautionary motive. This means that people keep money saved in case of unexpected events or emergencies, such as a sudden illness, job loss, or car repair. By having money set aside, they are better prepared to handle these situations and can avoid going into debt or facing financial hardship. In short, holding money for precautionary reasons is a way to protect one's financial security and peace of mind.

Awọn alaye Idahun

Commodities X and Y are substitutes. Substitute goods are products that can be used in place of each other. When the price of commodity X rises, consumers shift to commodity Y because it is a cheaper alternative to X. An example of substitute goods is coffee and tea - if the price of coffee increases, some people may switch to drinking tea instead.

Economic goods are termed scarce goods when they are

Awọn alaye Idahun

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

Nation engage in external trade because of difference in

Awọn alaye Idahun

Nations engage in external trade because of the differences in comparative cost, also known as comparative advantage. Comparative advantage is the ability of a country to produce goods or services at a lower opportunity cost than another country. Opportunity cost is the cost of one choice in terms of the best alternative that must be given up. In other words, it's the cost of producing one product in terms of the number of other products that could have been produced instead. For example, let's say that Country A can produce both cars and computers, but it can only produce one of them at a time. If Country A devotes all its resources to producing cars, it can produce 100,000 cars per year. If it devotes all its resources to producing computers, it can produce 50,000 computers per year. Meanwhile, Country B can produce 60,000 cars per year or 30,000 computers per year. In this case, Country A has a comparative advantage in producing cars because it has a lower opportunity cost of producing cars compared to computers. As a result, Country A can produce cars at a lower cost and sell them to Country B, which can in turn produce computers at a lower cost and sell them to Country A. This allows both countries to benefit from trade and improve their overall welfare. In summary, nations engage in external trade because of the differences in comparative cost, which allow countries to specialize in producing goods and services that they can produce more efficiently and trade with other countries for goods and services that they cannot produce efficiently. This creates mutual benefits for all countries involved.

Which of the following activities will not lead to economic growth?

Awọn alaye Idahun

Massive importation of consumer goods will not lead to economic growth. Economic growth refers to an increase in the capacity of an economy to produce goods and services over a period of time. It is measured by the growth in the gross domestic product (GDP) of a country. Massive importation of consumer goods may lead to an increase in consumption, but it does not lead to an increase in the productive capacity of an economy. This is because consumer goods are used for immediate consumption and do not contribute to the production of other goods and services. On the other hand, capital goods like machinery, equipment, and infrastructure are used to produce other goods and services, and their importation can lead to economic growth by increasing the productive capacity of an economy. Intensive capital formation and the use of modern technology also contribute to economic growth by increasing the efficiency and productivity of an economy.

A major function of the retailer is to

Awọn alaye Idahun

A major function of the retailer is to break bulk and sell products in small units to consumers. This means that retailers purchase goods in large quantities from wholesalers or manufacturers and then sell them in smaller quantities to individuals or households. By doing so, retailers make it easier for consumers to access a wide range of products, as they do not have to buy in bulk or directly from the manufacturer. Additionally, retailers often play a key role in generating demand for products through advertising and marketing efforts. By showcasing products in stores and online, and through various forms of advertising, retailers can help to build brand awareness and encourage consumers to purchase products. While some retailers may offer credit to wholesalers or consumers, this is not a primary function of retailing. Similarly, while retailers can help to reduce the cost of distribution by consolidating products and shipping them in bulk, this is a secondary function of retailing that supports the primary function of breaking bulk and selling products in small units.

Awọn alaye Idahun

Statutory organizations usually established by Acts of parliament are called public corporations. A public corporation is a type of legal entity that is established by the government through legislation to perform a specific function or provide a particular service to the public. Public corporations can be formed at the national, state, or local level, and can take a variety of forms depending on their specific mandate. While public enterprises are also entities that are owned and controlled by the government, they may not necessarily be established by Acts of parliament. Cooperative societies are typically voluntary organizations formed by individuals or businesses to pool resources and share risks, while joint-stock companies are privately owned businesses that are established to generate profit for their shareholders.

The pie chart above represent the total population of a school of 1,200. The shaded area of 60∘ shows the population of the underaged pupils.

What is the population of the matured students?

Awọn alaye Idahun

Since the entire pie chart represents the total population of the school, and the shaded area of 60∘ represents the underaged pupils, then the remaining unshaded area of the pie chart must represent the population of matured students. To find the measure of the unshaded area, we can subtract the measure of the shaded area from the total measure of the pie chart, which is 360∘ (since a circle has 360 degrees). So the unshaded area is: 360∘ - 60∘ = 300∘ The unshaded area of 300∘ represents the population of the matured students. To find the actual population of the matured students, we need to convert the 300∘ into a proportion of the total population. The proportion of the matured students is: 300∘ / 360∘ = 5/6 This means that the population of the matured students is 5/6 of the total population of the school, which is: (5/6) x 1200 = 1000 Therefore, the population of the matured students is 1000.

Which of the following forms of economic integration is a member nation free to impose duty against non-members

Awọn alaye Idahun

A free trade area is a form of economic integration where member nations agree to eliminate tariffs and trade barriers on goods and services traded among themselves. However, each member nation is still free to impose duties against non-member nations. In other words, members have a free trade agreement with each other, but they can still have their own trade policies towards non-members. In contrast, a customs union is an advanced form of a free trade area where member nations not only eliminate tariffs among themselves, but they also agree to have a common external tariff towards non-member nations. This means that all goods entering the customs union must pay the same tariffs, regardless of which member nation they are entering. A common market is a further step towards integration, where not only goods, but also factors of production such as capital and labor can freely move among member nations. This allows for a more integrated and efficient market, but it also means that member nations have less control over their trade policies. An economic community is a broader form of integration, where member nations agree to coordinate and harmonize their economic policies in a wide range of areas, including trade, monetary policy, and fiscal policy. This is the most advanced form of integration, as it involves a high degree of cooperation and coordination among member nations.

Commercial banks are different from development banks in that the latter

Awọn alaye Idahun

Commercial banks and development banks serve different functions within the financial system. Commercial banks are focused on providing financial services to individuals and businesses, such as deposit accounts, loans, and credit cards. They generally lend on a short-term basis and deal in a variety of currencies, including foreign currencies. In contrast, development banks are focused on promoting economic development and supporting long-term projects that may not be attractive to commercial banks. They typically provide financing for large infrastructure projects, such as highways, railways, and power plants, as well as small and medium-sized enterprises. Development banks may be government-owned, private, or a combination of both, and their main goal is to support economic growth and development. Development banks may also offer technical assistance and advisory services to help businesses and governments develop the skills and expertise needed to manage large-scale projects effectively. Unlike commercial banks, development banks may not pay interest on current accounts and may have different lending terms and requirements based on the specific needs of the project or business being financed.

In the long-run, a firm must shut down if its average revenue is

Awọn alaye Idahun

In the long-run, a firm should shut down if its average revenue is less than its average cost. This is because, in the long-run, all costs are considered variable, meaning the firm can adjust its production and input levels. If the firm continues to operate despite having average revenue less than average cost, it will continue to incur losses. To understand this concept, it's essential to know what the average revenue and average cost mean. Average revenue is the total revenue earned by a firm divided by the quantity of output produced. On the other hand, average cost is the total cost incurred by a firm divided by the quantity of output produced. The average cost can further be divided into two categories: average variable cost and average fixed cost. The average variable cost is the cost that varies with the level of output, such as labor and raw material costs. In contrast, the average fixed cost is the cost that remains constant regardless of the level of output, such as rent and salaries. So, in the long-run, a firm must shut down if its average revenue is less than its average cost because it means that the firm is not generating enough revenue to cover all its variable and fixed costs. By shutting down, the firm can avoid further losses and redirect its resources elsewhere. On the other hand, if the firm's average revenue is greater than its average cost, it can continue to operate and earn profits.

The effect of an increase in the personal income tax is to

Awọn alaye Idahun

The effect of an increase in the personal income tax is to reduce the disposable income of taxpayers. When personal income taxes are increased, taxpayers have less money to spend on goods and services, as more of their income is going towards taxes. This reduction in disposable income can lead to a decrease in consumer spending, which can have a negative impact on businesses and the economy as a whole. Increasing personal income taxes may also have a distorting effect on the economy, as it can create disincentives for individuals to work, save, and invest. However, it is not likely to raise the absolute price level, as this is determined by a variety of factors including supply and demand in the economy. Furthermore, an increase in personal income taxes is not directly linked to a reduction in unemployment, as this is influenced by a wide range of factors such as economic growth, labour market policies, and the overall state of the economy.

A major disadvantage of a capitalist economy is that it

Awọn alaye Idahun

The major disadvantage of a capitalist economy is that it worsens income inequality among the citizens. In a capitalist system, the means of production and distribution of goods and services are privately owned and operated for profit, leading to a concentration of wealth and power in the hands of a small group of people who own the most productive resources. This results in a situation where the rich get richer, while the poor get poorer, and there is a growing gap between the incomes and living standards of the wealthy and the less well-off members of society. This can create social unrest and political instability, as well as limit opportunities for social mobility and economic growth.

The mining sector of an economy contributes 60% to the Gross Domestic Product(GDP). If the GDP is $540, what is the contribution of the mining sector?

Awọn alaye Idahun

If the mining sector contributes 60% to the Gross Domestic Product (GDP), then its contribution can be calculated by multiplying the GDP by 60% (or 0.60, which is the decimal equivalent of 60%).

So, the contribution of the mining sector to the GDP is:

Contribution of mining sector = GDP x 60%

= $540 x 0.60

= $324

Therefore, the contribution of the mining sector to the GDP is $324. 

If the marginal utility of commodity is equal to its price, then

Awọn alaye Idahun

If the marginal utility of a commodity is equal to its price, then the consumer is in equilibrium. This means that the consumer is getting the maximum satisfaction possible from the commodity, given its price. If the marginal utility was greater than the price, the consumer would be willing to pay more for an additional unit of the commodity, indicating that they are not yet at their maximum level of satisfaction. Conversely, if the marginal utility was less than the price, the consumer would not be willing to pay the price for an additional unit, indicating that they have already exceeded their maximum level of satisfaction. Therefore, when the marginal utility is equal to the price, the consumer is in a state of balance, and does not want to consume more or less of the commodity.

The point x inside the ppc indicate?

Awọn alaye Idahun

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

A disadvantage of a jont-stock company is

Awọn alaye Idahun

A disadvantage of a joint-stock company is limited control in management by shareholders. In a joint-stock company, shareholders own a portion of the company and can make money by selling their shares for a profit or receiving dividends. However, shareholders do not typically have direct control over the day-to-day management of the company. Instead, a board of directors and executive management team make decisions on behalf of the company. This lack of control in management can be seen as a disadvantage for shareholders who may have different ideas about how the company should be run or who may not agree with the decisions made by the board or executive management team. Additionally, shareholders may not be able to influence the direction of the company as much as they would like. Overall, while joint-stock companies offer benefits such as limited liability for shareholders, this disadvantage in control over management may be a concern for some investors.

An effect of inflation is that it

Awọn alaye Idahun

An effect of inflation is that it "favors debtors at the expense of creditors." Inflation reduces the real value of money over time, which means that the value of debt also decreases. This can be an advantage for debtors, who are able to repay their debts with money that is worth less than when they borrowed it. In contrast, creditors are disadvantaged by inflation, as the value of the money they receive in repayment is worth less than the money they loaned out. Inflation can also have other effects, such as reducing the purchasing power of consumers, increasing uncertainty, and distorting economic decision-making.

An exceptional demand curve can result from

Awọn alaye Idahun

An exceptional demand curve can result from an expectation of future price increase. When people think that the price of a good or service is going to increase in the future, they may start buying more of it now in order to avoid paying the higher price later. This increase in demand can cause the price of the good or service to go up in the present, creating an exceptional demand curve that deviates from the typical downward-sloping demand curve. The other factors, such as an increase in the price of raw materials, increase in the size of the population, or change in taste of consumers, can also impact the demand for a good or service, but an expectation of future price increase is a unique factor that can result in an exceptional demand curve.

The main objective of marketing boards is to stabilize the incomes of cash crop farmers. Marketing boards help to regulate the supply and demand of cash crops, ensuring stable prices and incomes for farmers. They also provide support services to farmers, such as warehousing facilities and education on pricing, to help them sell their crops more effectively. While marketing boards may generate revenue for the government, their primary focus is on supporting and protecting the livelihoods of farmers.

Awọn alaye Idahun

The theory of comparative advantage states that a commodity should be produced in that nation where the opportunity cost is least. Opportunity cost is the cost of choosing one option over another, and in the context of comparative advantage, it refers to the cost of producing a particular good or service in terms of what has to be given up to produce it. A country should specialize in producing and exporting the goods and services for which it has a comparative advantage, which means that it can produce them at a lower opportunity cost than other countries. While the absolute cost and absolute money cost of production can be important factors in determining the competitiveness of a particular commodity, the theory of comparative advantage emphasizes the importance of considering opportunity cost. Furthermore, the production possibility curve, which shows the maximum combination of two goods that can be produced with a given set of resources, is not directly related to the theory of comparative advantage, although it can help illustrate some of the concepts involved in the theory.

In a pie chart, the population of a city is represented by 45. If the country has a population of 10 million people, then the city's population is?

Awọn alaye Idahun

To solve this problem, we need to first understand what a pie chart is and how it works. A pie chart is a circular graph that is divided into sectors, with each sector representing a proportion of the whole. The size of each sector is proportional to the quantity it represents, so we can use it to determine the percentage or fraction of the whole that each quantity represents.

In this case, the city's population is represented by 45 degrees of the pie chart. If we assume that the pie chart represents the entire country's population, which is 10 million people, then the fraction of the country's population represented by the city is:

45 degrees / 360 degrees = 1/8

This means that the city's population is 1/8 of the entire country's population. To find out the actual population of the city, we can multiply the fraction by the total population:

(1/8) x 10 million = 1.25 million

Therefore, the correct answer is 1.25 million.

A baker bought flour and other ingredients for S250.00, spent S52.00 on distribution, sold the bread for S320.00. The value added by the baker.

Awọn alaye Idahun

The value added by the baker is $90.00. To calculate the value added by the baker, we need to subtract the cost of goods sold (COGS) from the revenue. The COGS in this case includes the cost of flour and other ingredients, which is not given, but we know that the baker spent a total of $250.00 on these items. We also need to include the cost of distribution, which is $52.00. So the total COGS is $250.00 + $52.00 = $302.00. The revenue from selling the bread is $320.00. Therefore, the value added by the baker is $320.00 - $302.00 = $18.00. In other words, the baker added $18.00 of value to the raw materials and distribution costs to produce and sell the bread. This value added represents the baker's contribution to the economy and is a measure of the wealth created by the baker's business.

Fiscal policy measures imply a change in

Awọn alaye Idahun

Fiscal policy measures imply a change in government revenue and expenditure to regulate an economy. Fiscal policy is a tool used by governments to influence the economy by adjusting their spending levels and tax rates. This can be done by either increasing or decreasing government spending and taxes in order to achieve specific economic goals, such as controlling inflation, boosting employment, or promoting economic growth. For example, if the government wants to stimulate economic growth, it may increase its spending on infrastructure projects or offer tax incentives to businesses. Conversely, if the government wants to control inflation, it may decrease government spending and increase taxes to reduce the amount of money circulating in the economy. Therefore, fiscal policy measures involve making changes to both government revenue and expenditure in order to achieve specific economic objectives.

Awọn alaye Idahun

The term "Gross National Product (GNP) less the provision for the wear and tear of assets" refers to the Net National Product (NNP). The Net National Product (NNP) is a measure of the total economic output of a country, which takes into account the depreciation or wear and tear of the country's capital assets. Capital assets are things like buildings, machinery, and other long-term investments that contribute to a country's economic output. When we subtract the depreciation from the Gross National Product (GNP), which is the total value of goods and services produced by a country's residents, we arrive at the Net National Product (NNP). The reason we need to subtract depreciation from the GNP is that capital assets, such as buildings and machinery, wear out over time and lose value. If we didn't account for this loss of value, we would overestimate the country's economic output. For example, suppose the GNP of a country is $1 trillion, and the depreciation or wear and tear on its capital assets is $100 billion. In that case, the NNP of the country would be $900 billion ($1 trillion - $100 billion). In summary, the Net National Product (NNP) is the Gross National Product (GNP) minus the provision for the wear and tear of assets or depreciation. It gives us a more accurate measure of a country's economic output by accounting for the loss of value in capital assets over time.

Awọn alaye Idahun

The advantage which firms obtain directly from expanding their operations are referred to as "internal economies of scale." Internal economies of scale occur when a firm's average cost of production decreases as it increases the scale of its operations. This can be due to a variety of factors, such as increased specialization of labor, greater use of capital equipment, or better purchasing power for inputs. Internal economies of scale enable a firm to become more efficient and competitive as it grows, which can result in higher profits and a stronger market position. The opposite of internal economies of scale is internal diseconomies of scale, which occur when the average cost of production increases as a firm becomes too large or complex to manage efficiently.

If inflation is anticipated, people may choose to spend less money. This is because inflation reduces the purchasing power of money, meaning that the same amount of money can buy fewer goods and services. In response, people may decide to be more frugal with their spending, save more money, or look for ways to reduce their expenses. By spending less, they can try to maintain their purchasing power and avoid the negative effects of inflation.

Awọn alaye Idahun

The stock exchange is an example of a capital market. A capital market is a market where individuals and institutions trade financial securities, such as stocks and bonds, with the goal of raising capital. In other words, the capital market is where businesses can go to raise money by selling ownership in the company (stocks) or borrowing money (bonds) from investors. The stock exchange is a specific type of capital market where publicly-traded companies can sell ownership in the form of stocks to the public. Investors can buy and sell these stocks on the exchange, and the value of the stocks can rise or fall based on various factors, such as the company's financial performance, overall market conditions, and investor sentiment. Overall, the stock exchange and other capital markets play an important role in facilitating the flow of capital and resources throughout the economy, helping businesses raise funds to invest in growth and development, and providing investors with opportunities to earn a return on their investment.

Demand-pull inflation is likely to be caused by

Awọn alaye Idahun

Demand-pull inflation occurs when the overall demand for goods and services in an economy exceeds the supply of those goods and services, leading to an increase in the general price level. This increase in demand may be caused by a number of factors, such as an increase in consumer confidence, an increase in government spending, or an increase in exports. Out of the given options, an increasingly large budget deficit is the most likely cause of demand-pull inflation. When the government spends more money than it collects in taxes, it may finance the deficit by borrowing from the central bank, other banks or the public. This increases the overall amount of money in circulation in the economy, which in turn leads to an increase in demand for goods and services. This increased demand can then lead to higher prices for those goods and services, resulting in demand-pull inflation. An increase in the cost of factor inputs, such as labor or raw materials, may also contribute to inflation, but this is known as cost-push inflation, which occurs when the cost of producing goods and services increases, leading to higher prices. An increase in the income tax rate and an increase in the bank lending rate can reduce the overall demand for goods and services and lead to a decrease in inflation.

Awọn alaye Idahun

One possible factor that limits the extent of growth of a firm is the unwillingness to share ownership and control. When a firm is controlled by a single owner or a small group of owners who are not willing to share ownership or decision-making power, it can limit the firm's ability to raise capital, make strategic partnerships, or expand into new markets. In contrast, allowing outside investors or partners to have a stake in the company can provide the firm with access to more resources, expertise, and new opportunities for growth.

Under flexible exchange rates, a deficit could be corrected by

Awọn alaye Idahun

Under flexible exchange rates, a deficit could be corrected by the appreciation of other currencies. Flexible exchange rates are determined by market forces of supply and demand, without any government intervention. This means that the value of a country's currency can fluctuate based on changes in economic conditions and market expectations. In the case of a deficit, the demand for a country's currency will decrease, causing its value to fall relative to other currencies. This depreciation can make the country's exports cheaper and more competitive, while making imports more expensive, which can help correct the deficit. On the other hand, the appreciation of other currencies can make a country's exports more expensive and reduce demand for them, which can worsen the deficit.

What happens when the central bank increases the bank rate in an economy

Awọn alaye Idahun

When the central bank increases the bank rate, it becomes more expensive for banks to borrow money from the central bank. This in turn causes interest rates on loans and mortgages offered by commercial banks to increase as well. As a result, people and businesses are less likely to take out loans, because they have to pay more in interest. So, borrowing is discouraged. On the other hand, banks are able to charge more for loans, so they can increase their profits. However, this increase in interest rates can also lead to a decrease in spending, which can slow down economic growth.
