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?

Antwortdetails

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 government imposes a minimum price on a commodity

Antwortdetails

If the government imposes a minimum price on a commodity, it means that sellers cannot sell the commodity for a price lower than the minimum price set by the government. This is done to ensure that the producers of the commodity are getting a fair price for their goods. When a minimum price is set, it may result in excess supply (market surplus) of the commodity, as producers may be incentivized to produce more of the commodity at the higher price. However, the surplus can be reduced if the government buys the excess supply or if producers reduce their production. In the short-run, the market may be cleared, which means that all of the available supply of the commodity is sold at the minimum price set by the government. However, in the long-run, excess demand may occur as the minimum price may discourage buyers from purchasing the commodity. Therefore, government regulation may still be needed to ensure that the market operates efficiently, even with the minimum price in place.

An exceptional demand curve can result from

Antwortdetails

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 ordinary partner in a partnership

Antwortdetails

The ordinary partner in a partnership typically has unlimited liability in case of business failure. This means that they can be held personally liable for any debts or obligations of the business that are not satisfied by the assets of the partnership. This is a major disadvantage of a partnership, as it exposes the personal assets of the partners to the risk of loss in the event of business failure. While the extent of the involvement of the ordinary partner in the management of the business may vary, they are typically expected to take an active part in the management and decision-making of the partnership. As such, they cannot be said to take no active part in the management of the business. Furthermore, as a general rule, partners are jointly and severally liable for the actions of the partnership, which means that they can be sued personally on matters relating to the business. Limited liability, on the other hand, is a characteristic of some types of business entities such as limited liability companies (LLCs) and corporations.

The increase in the demand for a commodity may lead to a decrease in the demand for another if both are

Antwortdetails

The increase in the demand for a commodity may lead to a decrease in the demand for another if both are in competitive demand. When two goods are in competitive demand, they are seen as substitutes for each other, meaning that they can be used for the same purpose. For example, coffee and tea can be seen as substitutes for each other, since both are beverages that can be used to satisfy the same desire for a hot drink. So, if the demand for coffee increases, people may buy more coffee and less tea, because they see coffee as a substitute for tea. Similarly, if the demand for tea increases, people may buy more tea and less coffee, because they see tea as a substitute for coffee. On the other hand, if two goods are in complementary demand, they are often used together. For example, if the demand for cars increases, the demand for gasoline will also increase, since cars require gasoline to run. Similarly, if the demand for smartphones increases, the demand for phone cases may also increase, since people may want to protect their phones. In composite demand, a good has multiple uses, so an increase in demand for one use may not necessarily lead to a decrease in demand for another use. And in the case of goods of the same quality, an increase in demand for one good does not necessarily affect the demand for the other good, since they are not substitutes or complements.

A firm's average cost decreases in the long-run because of

Antwortdetails

A firm's average cost can decrease in the long-run due to increasing returns to scale. This means that as the firm increases its production, it experiences a decrease in its average cost. This can be due to various factors such as specialization, economies of scale, and better utilization of resources. For example, a firm that produces 100 units of a product might have an average cost of $10 per unit. However, if it increases its production to 200 units, it might be able to reduce its average cost to $8 per unit. This could be due to the fact that the firm can take advantage of bulk discounts on raw materials, use more efficient production methods, and spread its fixed costs over a larger number of units. Therefore, when a firm experiences increasing returns to scale, it can reduce its average cost in the long-run, which can lead to higher profits and a competitive advantage in the market.

Under flexible exchange rates, a deficit could be corrected by

Antwortdetails

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.

Statutory organisations usually established by Acts of parliament are called

Antwortdetails

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.

Antwortdetails

If workers at the school canteen cannot sell during the holidays, this is an example of seasonal unemployment. This means that the workers are temporarily out of work due to changes in demand for their labor, in this case because the school is not in session. Seasonal unemployment is a common occurrence in industries that are heavily influenced by the time of year, such as agriculture, tourism, and retail. While the workers may have other employment options, they are currently without work due to the seasonality of the school canteen.

The advantage which firms obtain directly from expanding their operations are referred to as

Antwortdetails

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.

The demand for labour is an example of

Antwortdetails

The demand for labor is an example of "derived demand." Derived demand refers to the demand for a factor of production or a good that arises as a result of the demand for another good or service. In the case of labor, it is not demanded for its own sake but rather because it is needed to produce goods and services that consumers demand. The demand for labor is therefore derived from the demand for the goods and services that labor helps to produce.

In a free market economy, the rationing of scarce goods is done principally by?

Antwortdetails

In a free market economy, the rationing of scarce goods is principally done by the price mechanism. The price of a good is determined by the forces of supply and demand in the market. When the supply of a good is limited and demand for it is high, the price of that good will increase. This higher price will serve as an incentive for producers to increase their supply of the good, and for consumers to reduce their demand for it. As a result, the scarce good will be rationed among consumers based on their willingness to pay the higher price. This process occurs naturally without the need for government intervention or control, and is a key feature of a free market economy.

Antwortdetails

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?

Antwortdetails

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.

Use it to answer this question.

If the budget of the country was $7,200, how much is allocated to Education?

Antwortdetails

Based on the pie chart, the Education sector is represented by 1/3 of the total budget allocation. To find out how much is allocated to Education, we can calculate 1/3 of the total budget: 1/3 x $7,200 = $2,400 Therefore, the answer is $2,400.00.

The theory of comparative advantage states that a commodity should be produced in that nation where the

Antwortdetails

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.

Antwortdetails

The concept described in the given scenario is called "double coincidence of wants." It refers to the situation where two parties have goods or services that the other party desires and are willing to exchange, and both parties are able to meet each other's wants at the same time. In the example, the housewife wants tomatoes, and she has meat that she can offer in exchange. However, she can only trade with someone who has tomatoes and also wants meat. The double coincidence of wants occurs when both parties have what the other wants, and both are willing and able to trade. This concept is important in understanding how bartering works, which is an exchange of goods and services without the use of money.

Economic goods are termed scarce when they are?

Antwortdetails

Economic goods are termed scarce when they are "not available in sufficient quantities to satisfy all wants for them." Scarce resources are those that have a limited supply relative to the demand for them. This scarcity means that choices must be made about how the resources are allocated, and that not all wants or needs can be fully satisfied. The concept of scarcity is fundamental to the study of economics, as it is the basis for understanding the concepts of opportunity cost, trade-offs, and efficiency.

Fixing the prices of agricultural products can be a problem because of the

Antwortdetails

Fixing the prices of agricultural products can be a problem because of the unpredictable output of farmers. Agricultural output can vary due to a variety of factors including weather, pests, disease, and other unpredictable factors. This variability can make it difficult to accurately predict the supply of agricultural products and set prices accordingly. While the instability of government policies, activities of marketing boards, and the size of agricultural exports can also have an impact on the pricing of agricultural products, the unpredictable output of farmers is a primary factor that can create challenges in setting prices. Instability of government policies can create uncertainty in the market, while the activities of marketing boards can sometimes lead to distortions in supply and demand. The size of agricultural exports can also influence prices by affecting the balance of supply and demand in domestic and international markets.

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

Antwortdetails

When the central bank increases the bank rate, it becomes more expensive for banks to borrow money from the central bank. This, in turn, leads banks to charge higher interest rates on loans they give to their customers. As a result, borrowing becomes more expensive for customers, so they might choose to borrow less money or pay off existing loans. This discourages borrowing and slows down the overall spending in the economy. On the other hand, since banks have to pay a higher interest rate to the central bank, they might be able to increase the interest they charge on loans, which would increase their profits. The increase in the bank rate does not directly impact the money supply in the economy. The central bank can use other tools, such as open market operations, to influence the money supply.

Antwortdetails

The effect of changes in the condition of demand on a demand schedule with the price constant is a shift of the demand curve. When there is a change in any factor that affects the quantity demanded at each price level, such as income, tastes and preferences, prices of related goods, or population, the entire demand curve shifts to a new position. This means that at each price level, the quantity demanded changes, leading to a new demand schedule. A movement along the demand curve occurs when there is a change in price, leading to a change in quantity demanded, while the other factors remain constant. Deflation or hyperbola formation are not terms typically used to describe changes in demand.

Marginal cost is?

Antwortdetails

Marginal cost refers to the cost of producing one additional unit of a good or service. It is the cost of producing the last or extra unit of output. This cost includes the variable costs of producing the additional unit, such as the cost of materials and labor, but it does not include fixed costs like rent or salaries, which do not change with the level of production. The concept of marginal cost is important in economics because it helps businesses and policymakers make decisions about how much to produce, what price to set for their goods or services, and whether to enter or exit a market. By analyzing their marginal costs, businesses can determine whether producing an additional unit of a good will be profitable or not.

Local firms can help in reducing unemployment in a country when

Antwortdetails

A greater burden of the taxes on essential goods is borne by the

Antwortdetails

A greater burden of the taxes on essential goods is typically borne by the lower income group. This is because essential goods such as food, clothing, and shelter make up a larger proportion of the budget of low-income households than they do for high-income households. When taxes are applied to these goods, the cost of living increases proportionally for low-income households, putting a greater burden on their limited resources. In contrast, high-income households can more easily absorb the higher costs without significantly affecting their standard of living.

Antwortdetails

In order to increase revenue, government should tax commodities for which demand is

Antwortdetails

When the demand for a commodity is perfectly price inelastic, it means that people will buy the same amount of the commodity no matter how much it costs. Therefore, if the government increases the tax on this commodity, people will still buy the same amount of it, and the tax revenue will increase. When the demand for a commodity is price inelastic, it means that people will buy a relatively small amount less of the commodity if the price increases. Therefore, if the government increases the tax on this commodity, people will still buy it, but they will pay more for it, and the tax revenue will increase. When the demand for a commodity is price elastic, it means that people will significantly reduce the amount they buy if the price increases. Therefore, if the government increases the tax on this commodity, people will buy less of it, and the tax revenue may not increase as much as expected. When the demand for a commodity is unitary elastic, it means that the change in quantity demanded is exactly proportional to the change in price. Therefore, if the government increases the tax on this commodity, the tax revenue will increase, but the increase in price may cause people to buy slightly less of it. Overall, if the demand for a commodity is relatively inelastic, the government may be able to increase revenue by increasing taxes on it. However, if the demand for a commodity is relatively elastic, the government may not be able to significantly increase revenue by increasing taxes on it, as people may switch to other alternatives or reduce their consumption of the commodity.

If W stands for wages/salaries, P for profits, R for interest and Z for rent on land and real estate, then national income is

Antwortdetails

If W stands for wages/salaries, P for profits, R for interest, and Z for rent on land and real estate, then the national income is given by:

W + P + R + Z

This is because national income is the total amount of income earned by individuals and firms within a country's borders, and it includes all four components of W, P, R, and Z.

Wages and salaries are earned by employees, profits are earned by business owners, interest is earned by lenders, and rent is earned by landlords. When we add up all of these components, we get the total national income.

Therefore, "W+P+R+Z," is the correct answer.

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

Antwortdetails

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.

The price mechanism 

Antwortdetails

The price mechanism is a system in an economy where the prices of goods and services are determined by the forces of supply and demand. This mechanism is responsible for regulating the balance between what consumers want to buy and what producers want to sell. As the demand for a particular item increases, the price of the item will rise, causing producers to increase supply to meet the demand. On the other hand, if the demand decreases, the price will fall, and producers will decrease their supply. In this way, the price mechanism helps allocate scarce resources by ensuring that the goods and services that are in high demand are produced and distributed more, while those that are not in high demand are produced and distributed less. In conclusion, the price mechanism does all of the above - regulates supply and demand, rations the consumers, rewards the producers, and allocates scarce resources - to ensure an efficient and effective allocation of resources in an economy.

A major disadvantage of a capitalist economy is that it

Antwortdetails

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.

Nation engage in external trade because of difference in

Antwortdetails

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.

An important factor hindering the rapid development of the industrial sector in Nigeria.

Antwortdetails

In the long run, all production factors are

Antwortdetails

In the long run, all production factors are "variable." This means that in the long run, a firm can adjust all of its production inputs, including labor, capital, and technology, to change the scale of its operations. In the short run, some inputs may be fixed, such as the size of the factory, which can only be changed in the long run. But in the long run, all inputs can be varied to optimize production and increase efficiency. The ability to adjust all inputs in the long run is what distinguishes the long run from the short run in the theory of production.

The use of the bank rate, cash ratio and open market operations constitute

Antwortdetails

The use of the bank rate, cash ratio, and open market operations are tools used in monetary policy. Monetary policy is a set of actions taken by a country's central bank to manage the supply of money and credit in the economy to achieve specific economic goals, such as controlling inflation, stabilizing prices, and promoting economic growth. The bank rate is the interest rate at which commercial banks can borrow money from the central bank. When the central bank increases the bank rate, it becomes more expensive for commercial banks to borrow money, which reduces the amount of money in circulation in the economy. Conversely, when the central bank lowers the bank rate, it becomes cheaper for commercial banks to borrow money, which increases the amount of money in circulation in the economy. The cash ratio is the percentage of deposits that commercial banks are required to hold in reserve with the central bank. When the central bank increases the cash ratio, it reduces the amount of money that commercial banks have available to lend, which reduces the amount of money in circulation in the economy. Conversely, when the central bank lowers the cash ratio, it increases the amount of money that commercial banks have available to lend, which increases the amount of money in circulation in the economy. Open market operations refer to the buying and selling of government securities by the central bank in the open market. When the central bank buys government securities, it injects money into the economy, which increases the amount of money in circulation. Conversely, when the central bank sells government securities, it withdraws money from the economy, which reduces the amount of money in circulation. So, the use of bank rate, cash ratio, and open market operations are all tools used in monetary policy to manage the amount of money in circulation in the economy, with the aim of achieving specific economic goals.

Under a floating exchange rate regime, the determinant of the exchange rate is

Antwortdetails

Under a floating exchange rate regime, the determinant of the exchange rate is "demand for and supply of foreign goods." In a floating exchange rate system, the exchange rate between two currencies is determined by the market forces of supply and demand. Factors such as interest rates, inflation rates, and trade flows can influence the demand for and supply of currencies, which in turn can affect the exchange rate. Unlike fixed exchange rate systems, where the exchange rate is determined by government policy, in a floating exchange rate system, the exchange rate can fluctuate based on market conditions.

The stock exchange is an example of the

Antwortdetails

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.

An example of transfer payments in national income accounting is

Antwortdetails

Transfer payments refer to payments made by the government or other institutions to individuals or other entities, without receiving any goods or services in return. These payments are typically made for social welfare purposes or to redistribute income. An example of a transfer payment in national income accounting is unemployment allowance paid to citizens who are unemployed. The government pays these allowances to support individuals who are currently out of work and seeking employment. This payment is considered a transfer payment because the government is not receiving any goods or services in return for the funds provided. Transfer payments are not included in the calculation of GDP because they do not represent the production of goods or services. However, they are important in measuring the overall economic well-being of a society, particularly in terms of income distribution and social welfare.
