Which of the following factors may not affect the efficiency of labour?

Maelezo ya Majibu

Among the given options, the factor that may not affect the efficiency of labor is the race and color of the workforce. The efficiency of labor refers to the amount of output that a worker can produce within a given time frame. Education and training can enhance workers' skills and knowledge, improving their ability to perform their jobs efficiently. Providing welfare services such as healthcare, childcare, and paid time off can also increase worker satisfaction and well-being, which can positively impact their productivity. The quality of other factor inputs, such as machinery, raw materials, and technology, can also have a significant impact on labor efficiency. High-quality inputs can facilitate and enhance workers' ability to produce more output in less time, increasing their efficiency. However, the race and color of the workforce do not inherently affect the efficiency of labor. A worker's productivity is determined by their individual skills, knowledge, and work ethic, regardless of their race or color. Discrimination based on race or color can negatively impact worker morale, job satisfaction, and opportunities, which can indirectly affect labor efficiency. Still, race or color itself is not a direct determinant of worker efficiency.

If the Central Bank increases its bank rate

Maelezo ya Majibu

If the Central Bank increases its bank rate, it means that it has increased the interest rate at which commercial banks can borrow money from the Central Bank. This, in turn, makes it more expensive for commercial banks to borrow money, which can have several effects on the economy. Firstly, since it is more expensive for banks to borrow money, they may become more cautious about lending money to their customers. This means that customers may find it more difficult to obtain loans or credit from banks, and the amount of borrowing may decrease. So, is not correct. Secondly, if banks find it more expensive to borrow money, they may also try to increase the interest rates they charge on loans and mortgages to maintain their profits. This could make borrowing more expensive for customers, and the interest charges by banks may rise rather than fall. So, is not correct. Thirdly, if the cost of borrowing money for commercial banks increases, they may not want to borrow as much money, which could reduce the supply of money in the economy. So, is correct. Lastly, an increase in the Central Bank's bank rate may not cause many banks to shut down their operations. However, some smaller banks or financial institutions that heavily rely on borrowing may struggle to stay afloat. So, is not correct. In conclusion, an increase in the Central Bank's bank rate can reduce the supply of money in the economy and increase the cost of borrowing for banks, which could result in higher interest rates for customers.

Palm oil and palm kernel are in

Maelezo ya Majibu

Palm oil and palm kernel are in joint supply. Joint supply refers to a situation in which two or more products are produced together as a result of a single production process. In the case of palm oil and palm kernel, both products are obtained from the same fruit of the oil palm tree. When the fruit is processed, it produces two distinct products: palm oil and palm kernel. Palm oil is obtained from the fleshy outer part of the fruit, while palm kernel is obtained from the inner seed or kernel. Since both products are obtained from the same production process, the quantity of one product that is produced is directly related to the quantity of the other product that is produced. As a result of being in joint supply, the prices of palm oil and palm kernel are interdependent. If the demand for one product increases, this will increase the supply of the other product, which can lower its price. For example, if the demand for palm oil increases, more oil palm fruit will be processed, leading to an increase in the supply of palm kernel and a potential decrease in its price. To summarize, palm oil and palm kernel are in joint supply because they are both obtained from the same production process and the quantity of one product produced is directly related to the quantity of the other product produced. The prices of both products are interdependent, and a change in demand for one product can affect the supply and price of the other product.

Which of the following is not emphasized in a product possibility curve?

Maelezo ya Majibu

The concept of unemployment of labor is not emphasized in a product possibility curve. A product possibility curve is a graphical representation of the trade-off between two goods that an economy can produce, given its limited resources and technology. The curve shows the maximum combinations of the two goods that can be produced with the available resources, taking into account that some resources are better suited for producing one good over the other. The emphasis is on the scarcity of resources and the efficiency with which they are being used, not on the employment of labor.

Which of the following industries will add more value to primary products?

Maelezo ya Majibu

The industry that adds more value to primary products is the processing industry. The processing industry takes raw materials, such as those produced by the mining industry, and turns them into finished products through various manufacturing processes. This added value comes from transforming the raw materials into something that is more useful and valuable to consumers. The service industry, on the other hand, provides services to individuals and businesses, such as consulting, financial advice, or customer support. While the service industry is important for the economy, it does not add value to primary products in the same way that the processing industry does. The construction industry involves the building of structures and infrastructure, such as buildings, roads, and bridges. While the construction industry uses materials produced by the mining industry, it does not add value to these materials in the same way that the processing industry does. In conclusion, the processing industry is the industry that adds the most value to primary products by transforming raw materials into finished goods that are more useful and valuable to consumers.

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

Maelezo ya Majibu

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 major role of multi-national companies in the petroleum industry in Nigeria is

Maelezo ya Majibu

The major role of multi-national companies in the petroleum industry in Nigeria is oil prospecting. These companies typically invest heavily in exploration, drilling, and production of crude oil in Nigeria, which is one of the largest oil-producing countries in Africa. The multi-national companies also play a significant role in the development of Nigeria's oil and gas infrastructure, including pipelines, storage facilities, and export terminals, which are necessary for getting the oil to international markets. While some of these companies are also involved in downstream activities such as oil marketing and refining, their primary role in Nigeria's petroleum industry is oil exploration and production.

Wholesalers play an important in the distribution of goods and services because they

Maelezo ya Majibu

Wholesalers play an important role in the distribution of goods and services because they act as intermediaries between producers and retailers. Wholesalers buy goods in large quantities from producers and then sell them in smaller quantities to retailers. This enables producers to focus on their production process without worrying about marketing and distribution. On the other hand, retailers can buy smaller quantities of goods from wholesalers, which allows them to stock a variety of products without having to buy in bulk. Wholesalers also provide other important services, such as financing and logistics. They may provide credit to both producers and retailers, allowing them to manage their cash flow and invest in their businesses. Additionally, wholesalers can handle the transportation and storage of goods, which can be a complex and expensive task for smaller businesses. Therefore, wholesalers play a crucial role in the distribution process, providing valuable services and enabling the smooth flow of goods and services from producers to retailers, and ultimately to consumers.

Maelezo ya Majibu

If a demand curve that intersects a perfectly inelastic supply shifts rightward, the equilibrium price will increase, but the quantity supplied will remain the same. In this scenario, a shift in the demand curve to the right indicates that there is an increase in demand for the product at every price level, leading to a new equilibrium price and quantity. However, the supply is perfectly inelastic, meaning that the quantity supplied cannot increase to meet the new demand. Therefore, the equilibrium quantity remains the same, while the equilibrium price increases. So, only the price will increase in this scenario.

Budget deficit is the amount by which

Maelezo ya Majibu

Budget deficit is the amount by which total expenditure exceeds revenue. A budget deficit occurs when a government or organization spends more money than it takes in through revenue, such as taxes or other sources of income. This can result in the accumulation of debt over time, which can have long-term implications for the financial health of the government or organization. While recurrent expenditure and capital expenditure are both types of expenditures that can contribute to a budget deficit, neither of these terms captures the full picture of a budget deficit. Recurrent expenditure refers to ongoing or routine expenses such as salaries, utilities, and other operating costs, while capital expenditure refers to spending on assets such as buildings, equipment, and infrastructure. A budget deficit can result from either type of expenditure, as well as from other sources of spending such as debt servicing or unexpected events that require emergency spending.

If the quantity demanded of a commodity increases from 20 units to 30 units when there is an increase in price from $4.00 to $5.00, the elasticity of demand is

Maelezo ya Majibu

The elasticity of demand measures the responsiveness of the quantity demanded of a commodity to a change in its price. In this case, when the price of the commodity increased from $4.00 to $5.00, the quantity demanded increased from 20 units to 30 units. To calculate the elasticity of demand, we use the following formula: Elasticity of demand = (percent change in quantity demanded) / (percent change in price) First, let's find the percent change in quantity demanded: (30 units - 20 units) / 20 units = 0.50 or 50% Next, let's find the percent change in price: (5.00 - 4.00) / 4.00 = 0.25 or 25% Finally, let's plug in the values into the formula: Elasticity of demand = 0.50 / 0.25 = 2.00 So, the elasticity of demand in this case is 2.00. This means that a 1% increase in price leads to a 2% decrease in the quantity demanded.

Under flexible exchange rates, a deficit could be corrected by

Maelezo ya Majibu

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.

The major role of multi-national companies in the petroleum industry in Nigeria is

Maelezo ya Majibu

The major role of multinational companies in the petroleum industry in Nigeria is oil prospecting. Multinational companies, also known as International Oil Companies (IOCs), play a significant role in the exploration and production of oil and gas in Nigeria. These companies invest heavily in the exploration of new oil fields, as well as the development and production of existing fields. While some IOCs are also involved in oil marketing and refining, their primary role in Nigeria is oil prospecting. The IOCs in Nigeria include major companies such as Shell, ExxonMobil, Chevron, and Total.

Which of the following factors is not a cause of diminishing returns?

Maelezo ya Majibu

The factor that is not a cause of diminishing returns is "Technological innovations". Diminishing returns refers to the decrease in marginal output or production as more units of a variable input (such as labor or capital) are added to a fixed amount of other inputs (such as land or machinery). This occurs because the fixed inputs become increasingly scarce relative to the variable inputs, which can lead to inefficiencies and reduced productivity. The other three factors listed - an increase in variable inputs, land fragmentation, and constant technology - can all contribute to diminishing returns. For example, adding more workers to a fixed amount of land may lead to overcrowding and reduced productivity (land fragmentation). Similarly, if technology remains constant while more inputs are added, the additional inputs may not be fully utilized and may even become redundant. In contrast, technological innovations can actually help to overcome diminishing returns by allowing for more efficient use of inputs and increasing productivity. New technologies can improve the efficiency of production processes, reduce waste, and create new products or services, all of which can lead to increased output and economic growth.

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

Maelezo ya Majibu

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.

A major disadvantage of a capitalist economy is that it

Maelezo ya Majibu

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.

If workers at the school canteen cannot sell during the holidays, this is example of

Maelezo ya Majibu

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 demand for labour is an example of

Maelezo ya Majibu

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.

Statutory organisations usually established by Acts of parliament are called

Maelezo ya Majibu

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.

Maelezo ya Majibu

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.

In the event of bankruptcy, owners of joint-stock companies lose

Maelezo ya Majibu

In the event of bankruptcy, owners of joint-stock companies (also known as shareholders) typically only lose the capital they have invested in the company. They do not lose their private properties or personal assets. When an individual buys shares in a joint-stock company, they become a partial owner of the company. As a shareholder, they are entitled to receive a share of the company's profits in the form of dividends. However, if the company goes bankrupt and cannot meet its financial obligations, the shareholders may lose the value of their investment, meaning the shares they hold in the company become worthless. Therefore, shareholders may lose the capital they invested in the company, but they are not responsible for any additional debts or liabilities the company may have. Shareholders are only liable to lose the value of their shares and do not have to worry about losing their personal assets or private properties.

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

Maelezo ya Majibu

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.

A possible factor which limits the extent of growth of a firm is the

Maelezo ya Majibu

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.

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

Maelezo ya Majibu

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 type of unemployment found among workers who leave their jobs in search of other jobs is termed

Maelezo ya Majibu

The type of unemployment found among workers who leave their jobs in search of other jobs is called frictional unemployment. This occurs when individuals are between jobs and are actively searching for new employment opportunities. Frictional unemployment is typically short-term and is a natural part of the job search process. It can occur due to various reasons such as workers seeking better job opportunities, moving to a new location, or recently graduating from school. Although frictional unemployment may be a temporary situation for individuals, it can have an impact on the economy if the time taken to find a new job is prolonged. However, it is generally seen as a less problematic form of unemployment than other types, such as structural or cyclical unemployment, which can have more severe and long-lasting effects on the economy.

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?

Maelezo ya Majibu

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. 

The stock exchange is an example of the

Maelezo ya Majibu

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.

Gross National Product (GNP) less the provision for the wear and tear of assets is the

Maelezo ya Majibu

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.

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

Maelezo ya Majibu

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.

A consumer of a single commodity is in equilibrium when

Maelezo ya Majibu

A consumer of a single commodity is in equilibrium when they have reached a point where they are satisfied with the amount of the commodity they have purchased and consumed, and do not feel the need to buy any more or any less of it. This equilibrium can be achieved in different ways, but one common way is when the marginal utility, or the additional satisfaction gained from consuming one more unit of the commodity, is equal to the price paid for that unit. In other words, the consumer is willing to pay the price because they feel they are getting enough satisfaction from the additional unit. At this point, the consumer has no incentive to buy more of the commodity, because the marginal utility would be lower than the price, and they would feel like they are overpaying for the satisfaction gained. Conversely, if the price were to decrease, the marginal utility would be higher than the price, and the consumer may feel like they are getting a good deal and may want to purchase more of the commodity. Ultimately, the consumer is in equilibrium when they have found a balance between the satisfaction gained from the commodity and the price paid for it.

Economic goods are termed scarce when they are?

Maelezo ya Majibu

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.

Marginal cost is?

Maelezo ya Majibu

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.

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?

Maelezo ya Majibu

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 country's budget allocation to various sectors of the economy is shown in the pie chart above...

Use it to answer this question.

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

Maelezo ya Majibu

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.

A disadvantage of a joint-stock company is

Maelezo ya Majibu

A disadvantage of a joint-stock company is the potential for loss of controlling interest. In a joint-stock company, ownership is divided into shares, which can be bought and sold by individual shareholders. If a large number of shares are sold to other individuals or entities, it can dilute the ownership and control of the original shareholders, making it more difficult for them to have a significant say in the decision-making process. Limited liability is actually an advantage of a joint-stock company, as it protects shareholders from personal financial liability beyond their investment in the company. Continuity is also an advantage of a joint-stock company, as it can continue to exist even if shareholders come and go or if one or more shareholders die. Unlimited liability, on the other hand, is a disadvantage of a sole proprietorship or partnership, where the owner or partners can be held personally liable for the debts and obligations of the business.
