Economists refer to private goods as

Antwoorddetails

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

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

Antwoorddetails

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

Government uses all of the following ways to redistribute income, except

Antwoorddetails

The government uses various methods to redistribute income in society. Three of these ways are market intervention, transfer earnings, and taxation. Market intervention involves the government stepping in and regulating certain aspects of the economy to ensure fairness and reduce income inequality. For example, the government may set a minimum wage so that workers are guaranteed a certain level of income. Transfer earnings refer to government programs that provide financial assistance to individuals or families who are in need. These programs include welfare, unemployment benefits, and social security. The goal is to provide support to those who may have lower incomes or are facing financial difficulties. Taxation is another method used by the government to redistribute income. Through taxes, the government collects money from individuals and businesses based on their income or profits. This revenue is then used to fund public services such as healthcare, education, infrastructure, and social programs. However, the answer to the question is that the government does not use limited liability as a way to redistribute income. Limited liability is a legal concept that protects individuals from being personally liable for the debts and liabilities of a company. It is not directly related to income redistribution. In summary, the government redistributes income through market intervention, transfer earnings, and taxation. These methods aim to promote fairness and provide support to those in need. However, limited liability is not a method used for income redistribution.

Suppose the public expenditure as a percentage of GDP of four countries is shown in the table below

Which type of economy exists in these countries?

Antwoorddetails

The type of economy that exists in these countries is Mixed economy.

A mixed economy is an economic system that combines elements of both market and planned economies. It includes both private and public sectors, and the government plays a significant role in regulating and defining the structure of the economy.

In the given scenario, the fact that the countries have different levels of public expenditure as a percentage of GDP indicates that the government plays a role in the economy and is involved in spending a portion of the national income.

While the exact percentage of public expenditure varies between the countries, the presence of any public expenditure suggests government intervention and regulation in the economy. This means that these countries have a mixed economy, where both public and private sectors coexist and contribute to economic activities.

The government's involvement can take various forms, such as funding public goods and services, implementing social programs, and regulating industries. The level of government intervention may vary, but the presence of public expenditure indicates that the government has an active role in shaping the economy.

Therefore, based on the information provided, it can be concluded that the countries mentioned in the table have a mixed economy.

Which of the following is the resultant effect of a fall in the profit margin of producers in an economy?

Antwoorddetails

A fall in the profit margin of producers in an economy will likely result in an increase in unemployment.
When the profit margin of producers decreases, it means that they are earning less profit from their business activities. As a result, they may struggle to cover their costs, sustain their operations, or expand their businesses. To manage their financial situation, producers may need to cut costs, reduce production, or even close down their business altogether.
Reduced production and business closures lead to a decrease in job opportunities and an increase in unemployment. When businesses are not making enough profit, they may need to lay off workers or reduce their workforce in order to cut costs. This means that fewer people will have jobs, resulting in higher unemployment rates.
Additionally, a fall in profit margins can also deter new businesses from entering the market or existing businesses from expanding. This further limits job creation and can exacerbate the unemployment problem.
In summary, a fall in the profit margin of producers in an economy leads to reduced production, business closures, job cuts, and a decrease in job opportunities. Therefore, the most likely resultant effect of such a decline in profit margin is an increase in unemployment.

The marginal propensity to consume (MPC) is a measure of how much of an increase in income is typically spent on consumption. It is represented by the symbol c or ΔC/ΔY. To explain it simply, the MPC tells us the proportion of additional income that is used for consumption rather than saving or other purposes. For example, if the MPC is 0.8, it means that for every additional unit of income, 0.8 units are typically spent on consumption. The MPC can also be understood as the slope of the consumption function. The consumption function is a mathematical relationship between income and consumption. The MPC represents how much consumption changes for a given change in income. In the equation C = C + cYd, the coefficient c represents the MPC. This equation shows that consumption (C) is determined by autonomous consumption (C) plus the product of the MPC (c) and disposable income (Yd). In summary, the MPC is a measure of how much additional income is typically used for consumption. It can be represented as ΔC/ΔY, the slope of the consumption function, or the coefficient c in the consumption equation.

When a kilogram of carrot is #8.00, 20 kilograms are demanded and when the price decreased to #6.000 per kilogram, 30 kilograms are demanded. The elasticity of demand equals to

Antwoorddetails

To calculate the elasticity of demand, we need to compare the changes in price and quantity demanded.
First, let's calculate the percentage change in price:
% change in price = ((new price - old price) / old price) x 100
% change in price = ((6 - 8) / 8) x 100
% change in price = (-2 / 8) x 100
% change in price = -25%
Next, let's calculate the percentage change in quantity demanded:
% change in quantity demanded = ((new quantity demanded - old quantity demanded) / old quantity demanded) x 100
% change in quantity demanded = ((30 - 20) / 20) x 100
% change in quantity demanded = (10 / 20) x 100
% change in quantity demanded = 50%
Now, let's calculate the elasticity of demand:
Elasticity of demand = % change in quantity demanded / % change in price
Elasticity of demand = 50% / -25%
Elasticity of demand = -2
The elasticity of demand is -2.
Explanation:
The negative sign in the elasticity of demand (-2) indicates that the demand for carrots is price elastic. This means that a decrease in price by 1% will lead to a more than proportionate increase in quantity demanded by 2%. In simpler terms, when the price of carrots decreased by 25%, the quantity demanded increased by 50%.
Therefore, the elasticity of demand is -2, which means that the demand for carrots is price elastic.

But since price elasticity is always represented with a positive number, the answer is 2

The number of people who are qualified to work and who offered themselves for employment are called

Antwoorddetails

The correct term for the number of people who are qualified to work and who offer themselves for employment is the working population.
The working population refers to the subset of the total population that is actively engaged or seeking employment. It includes individuals who are qualified, available, and willing to work. This encompasses both employed individuals and those who are actively looking for work, such as job seekers.
The working population is an important measure for understanding the labor market. It helps policymakers, businesses, and economists in assessing the job market's health and determining factors such as employment rates, labor force participation, and unemployment rates.
Options like "mobility of labor" and "migrant labor" focus on the movement of workers between different locations, which is a related concept but not the same as the total number of qualified individuals available for employment. "Labor turnover" refers to the rate at which workers leave and join a particular company or industry, which is also not synonymous with the working population as a whole.
Therefore, the working population is the term that correctly describes the number of qualified individuals who are available for employment.

An increase in money income with constant price results in

Antwoorddetails

When there is an increase in money income but the prices of goods and services remain the same, it will result in an outward shift in the budget line. To understand this, let's imagine a simple scenario where a person has a fixed amount of money to spend on different goods and services. This fixed amount of money represents their income. Now, if their income increases but the prices of goods and services they want to buy stay the same, they will have more money to spend. This means they can afford to buy more of each item. As a result, the budget line, which shows the different combinations of goods and services that can be bought with a given income, will shift outward. This indicates that they can now afford to buy a greater quantity of goods and services than before. Therefore, the correct answer is an "outward shift in the budget line" when there is an increase in money income with constant prices.

The principle that specified that the amount, when and how to pay tax should be made known to tax payer is known as

Antwoorddetails

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

Antwoorddetails

In a two by two model of international trade, it is assumed that **both countries could gain from trade at the same time, but the volume of the gains depends on terms of trade**. This means that both countries can benefit from engaging in trade with each other. Trade allows both countries to specialize in producing and exporting the goods in which they have a comparative advantage, while importing goods that they are less efficient at producing. This leads to increased efficiency and overall economic gains for both countries. However, the volume of the gains from trade depends on the terms of trade between the two countries. The terms of trade refer to the ratio at which the countries exchange their goods. If one country has a higher bargaining power or can produce goods at a lower cost, they may negotiate more favorable terms of trade, leading to a larger volume of gains for that country. On the other hand, if the terms of trade are less favorable, the volume of gains for both countries may be smaller. In summary, while both countries can benefit from trade, the extent of the gains will vary depending on the terms of trade negotiated between them.

From the graph above, the consumer is at equilibrium at point

Antwoorddetails

Based on the graph, the consumer is at equilibrium at point k.

Equilibrium is when the quantity demanded by the consumer is equal to the quantity supplied by the market. At equilibrium, there is no shortage or surplus of the goods or services.

Point k on the graph represents the intersection of the demand curve (D) and the supply curve (S). At this point, the quantity demanded (Qd) and the quantity supplied (Qs) are equal.

If the consumer is at any other point on the graph, either to the left or to the right of point k, there would be either a shortage or a surplus of the goods or services. This would mean that the demand and supply are not in balance and the market is not at equilibrium.

Therefore, point k is the correct answer as it represents the position where the consumer is at equilibrium.

Antwoorddetails

To find the value of L when the supply (s) is equal to 20, we can use the given supply curve equation: S = 4L + 8.
The supply curve equation represents how much labor (L) will be supplied at a given wage rate (s). In this case, the equation tells us that the supply of labor is equal to 4 times the quantity of labor (L) plus 8.
To find L when s = 20, let's substitute s = 20 into the equation:
20 = 4L + 8
Next, let's isolate L by subtracting 8 from both sides of the equation:
20 - 8 = 4L
Simplifying further:
12 = 4L
Now, we need to solve for L. We can do this by dividing both sides of the equation by 4:
12/4 = 4L/4
Simplifying again:
3 = L
Therefore, when the supply (s) is equal to 20, the value of L is 3.
So the correct answer is 3.

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

Antwoorddetails

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

.............is presently used in Nigeria to measure inflation

Antwoorddetails

The measure that is presently used in Nigeria to measure inflation is the Consumer Price Index (CPI). The CPI is a commonly used indicator worldwide to track changes in the cost of living over time.
The Consumer Price Index (CPI) measures the average price changes of a basket of goods and services typically purchased by households in a specific country or region. It reflects the price movements of essential items such as food, housing, transportation, healthcare, education, and many other goods and services that people consume regularly.
The CPI is calculated by collecting price data for various items in the basket and assigning them weights based on their relative importance in household spending. The prices are then compared to a base period, which is usually a specific year. The percentage change in the CPI from the base period indicates the rate of inflation or deflation.
In Nigeria, the CPI is used to monitor and analyze changes in the cost of goods and services, allowing policymakers and economists to assess the impact on consumers' purchasing power and make informed decisions. It helps in determining the effectiveness of government policies, evaluating the performance of the economy, and adjusting wages and prices.
By tracking the CPI, the government can identify if there is an increase in the general level of prices, indicating inflation, or a decrease, indicating deflation. This information helps in formulating monetary and fiscal policies to control inflation rates and maintain price stability.
Overall, the Consumer Price Index (CPI) is the measure currently used in Nigeria to gauge inflation and is crucial in understanding how the cost of living changes over time, impacting the economy and the daily lives of individuals and businesses.

The type of price elasticity of demand for a commodity whose quantity demanded remain unchanged despite changes in the price is

Antwoorddetails

The type of price elasticity of demand for a commodity whose quantity demanded remains unchanged despite changes in the price is **perfectly inelastic**. When the demand for a commodity is perfectly inelastic, it means that the quantity demanded does not respond at all to changes in price. This usually occurs when there are no close substitutes for the commodity, or when the commodity is a necessity that people cannot easily do without. To understand it in a simple way, imagine a situation where the price of a life-saving medication for a critical illness increases significantly. In such a case, even if the price increases, the quantity demanded for the medication will remain the same because the individuals who need it have no other option but to purchase it at any cost. Therefore, the demand for such a medication is perfectly inelastic, as it does not change with variations in price. In summary, when the demand for a commodity is perfectly inelastic, it means that consumers are willing to pay any price for it, and the quantity demanded does not change despite fluctuations in price.

Indicator of underdevelopment is

Antwoorddetails

An indicator of underdevelopment is low per capita income. Per capita income refers to the average income earned by individuals in a country. In underdeveloped countries, the per capita income is generally low, meaning that people have lower incomes on average compared to developed countries.
Low per capita income is a significant indicator of underdevelopment because it directly affects the standard of living of people within a country. With low income, individuals have limited purchasing power, making it difficult for them to afford basic necessities such as food, clothing, and shelter. This can lead to overall poor living conditions and a lack of access to essential services like healthcare and education.
Additionally, low per capita income also implies limited economic opportunities and a weak economy. It suggests that the country's productivity and industrial development are low, leading to low wages and limited job opportunities. This can result in high levels of poverty and unemployment, further hindering the country's development.
In summary, low per capita income is a crucial indicator of underdevelopment because it reflects the overall economic situation of a country and directly impacts the living conditions and opportunities available to its citizens.

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

Antwoorddetails

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

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

Let's understand this further:

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

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

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

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

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

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

Antwoorddetails

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

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

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

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

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

An example of a free good is water in the ocean.

A free good is a good that is available in unlimited supply and does not require any payment or exchange to obtain it.

In the case of water in the ocean, it is freely available and accessible to anyone. It is not owned by anyone and does not require any payment to access or use it. Therefore, it can be considered a free good.

On the other hand, free education, dinner you did not pay for, and your rented apartment are not examples of free goods.

Free education typically refers to education that is provided without direct payment by the student. While it may be free for the student, someone is still paying for it, such as the government or private institutions.

A dinner that you did not pay for may seem free to you, but someone, such as a friend or a host, is still paying for it. The cost of that dinner is borne by someone else, even if it is not you.

Similarly, a rented apartment is not a free good because it involves a transaction where you pay for the use of the apartment. You enter into a contractual agreement with the landlord and pay rent in exchange for living in the apartment.

Part-time workers who desire full-time employment are:

Antwoorddetails

Part-time workers who desire full-time employment are classified as underemployed and contribute to the unemployment statistic.
Underemployment refers to a situation where individuals are working fewer hours than they would like or in jobs that do not utilize their skills and qualifications fully. In this case, part-time workers who desire full-time employment are considered underemployed because they are not able to secure the desired amount of work hours.
These underemployed workers contribute to the unemployment statistic because they are actively seeking additional work hours to meet their employment needs. They are considered part of the labor force because they are willing and available to work more hours, but they have not been able to find full-time employment.
It is important to note that not all underemployed workers contribute to the unemployment statistic. Some may choose to work part-time for personal reasons, such as family responsibilities or pursuing education. These individuals, although underemployed, are not actively seeking additional work hours and therefore do not contribute to the unemployment statistic.
However, in the case of individuals who are part-time workers and desire full-time employment, their underemployment status reflects the inadequacy of available job opportunities. They increase the count of unemployed individuals because they are willing and actively searching for additional work.
It is worth mentioning that cyclical unemployment is a different type of unemployment. It occurs when there is a downturn in the economy, causing a decrease in overall demand for goods and services, and subsequently, a decrease in the demand for labor. Cyclical unemployment is not directly related to the part-time workers' desire for full-time employment.

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

Antwoorddetails

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

An increase in nominal income without increase in price will result to

Antwoorddetails

An increase in nominal income without an increase in prices will result in an **increased real income**. Nominal income refers to the amount of money a person earns or receives in a given period, without taking into account changes in prices. On the other hand, real income takes into consideration the effects of inflation by adjusting for changes in prices. When nominal income increases but prices remain constant, it means that the purchasing power of an individual's income has increased. In other words, they can afford to buy more goods and services with the same amount of money. This increase in purchasing power leads to an increase in real income. For example, let's say a person's nominal income is $1,000 per month, and the prices of goods and services they consume also remain constant. If their nominal income increases to $1,200 per month, without any increase in prices, they now have an additional $200 to spend on other things. This additional purchasing power translates to an increase in their real income. It is important to note that an increase in nominal income without an increase in prices does not necessarily lead to an **increased GDP** or a **decreased GNP**. GDP (Gross Domestic Product) measures the total value of goods and services produced within a country's borders, while GNP (Gross National Product) measures the total value of goods and services produced by a country's residents, including those produced abroad. The increase in real income of individuals does not automatically impact the overall production levels captured by GDP or GNP.
