The **variance** of a set of numbers is a measure of how much the numbers in the set differ from the mean (average) of the set. It is calculated as the average of the squared differences from the mean.

The **standard deviation** is simply the square root of the variance. It gives a measure of how spread out the numbers in the set are, using the same units as the original numbers.

Given that the standard deviation of a set of numbers is **3.6**, you can find the variance by squaring the standard deviation. This is because the variance is the square of the standard deviation.

So you calculate the variance as follows:

Variance = (Standard Deviation)² = **3.6** x **3.6** = **12.96**

So the **variance** is **12.96**.

In any economy, the problem of "how to produce" is essentially about deciding the best way to combine resources to produce goods and services. This challenge can be effectively addressed by adopting the least cost method of production.

Here’s why:

• Objective: The key objective for any economy is to produce goods and services efficiently, using the least amount of resources possible, while maximizing output. This ensures that the resources, which are often limited, are utilized in the most productive way.


• Resource Allocation: By focusing on the least cost method, producers aim to determine the proportion of capital (like machines, tools, and buildings) and labor (human effort) that should be used to minimize costs and maximize profits. This can involve a mix of both capital and labor-intensive methods depending on which combination minimizes production costs.
• Flexibility: The least cost method is iterative and allows for adjustments based on changes in resource availability, technological advancements, and shifts in market conditions, ensuring the production process remains cost-effective and competitive.


• Consumer Benefits: When producers focus on minimizing costs, they can offer products at lower prices, making goods and services more affordable for consumers, which can increase demand and boost the overall economy.

In summary, while other methods and managerial skills are important, addressing how to produce in the most efficient and effective way often boils down to using the least cost method of production, thereby ensuring optimal resource use and economic stability.

The concept you are referring to is effective demand. Let me explain it to you in a straightforward way:

Demand: Generally, demand refers to the desire or willingness of a consumer to purchase goods or services. However, just having the desire is not enough. Demand becomes impactful only when it is supported with the capability to purchase.

Effective demand: This is more than just a simple desire or demand. It represents the situation where an individual not only wants to purchase a product or service but also has the actual purchasing power to do so. This means they have the money or resources to back up their desire at a given time.

Desire: This term simply denotes a wish or want, without any implication of capability to fulfill it. For instance, many people might desire a luxury car, but not everyone can afford it.

Utility: This is a different concept entirely, referring to the satisfaction or benefit a consumer receives from consuming a product or service. It does not necessarily align with the ability to purchase.

In summary, when discussing the willingness to buy something and having the funds ready at that moment, it's referred to as effective demand because it combines the desire with the actual capacity to fulfill that desire.

The diagram you are referring to represents the Circular Flow of Income. This is a crucial concept in economics that demonstrates how money moves within an economy between different sectors. Let me explain it further in a simple and clear manner.

The Circular Flow of Income exhibits the interactions and transactions that occur between two major groups in an economy: the households and the firms. It is important to note that:

• Households: They are the owners of factors of production such as labor, land, and capital. Households provide these resources to firms.
• Firms: They produce goods and services using the factors of production provided by households. Firms pay households for these resources in the form of wages, rent, interest, and profits.

The flow of economic resources and money can be explained in two key types:

• Real Flow: This involves the flow of actual goods and services from firms to households, and the flow of factors of production from households to firms.
• Monetary Flow: This involves the flow of money in the form of payments made by firms to households for their resources, and the flow of money from households to firms to purchase goods and services.

In an expanded model of the circular flow, other components may be included, such as the government, financial sector, and foreign markets, which illustrate additional flows such as taxes, government spending, savings, investments, and exports/imports.

Overall, the Circular Flow of Income provides a fundamental understanding of how economic activity is interconnected and how different sectors interact with one another in a continuous cycle.

When an economy is experiencing a balance of payments surplus, it means that the country is exporting more goods, services, and capital than it is importing. Essentially, there is more money flowing into the country than out of it. In such situations, one of the most viable actions to take is to increase its foreign reserves.

Here's why increasing foreign reserves is often the best option:

• Stability and Security: Increasing foreign reserves can help the country maintain better economic stability and provide a financial cushion. These reserves can be used in times of economic distress, for example, to stabilize the country's currency or to cover the balance of payments deficit if one arises in the future.
• Credibility and Investor Confidence: A healthy level of foreign reserves signals to international investors and creditors that the country is financially stable, which can lead to greater investor confidence and potentially more foreign investment.
• Currency Support: With a surplus, increasing reserves can support the country's currency value in global financial markets. This helps maintain favorable exchange rates and can be used strategically by the central bank to control currency appreciation.
• Flexibility in Monetary Policy: Higher foreign reserves give the central bank more flexibility in its monetary interventions. They can control inflation and manage interest rates more effectively.

Promoting imports, while it can help reduce the surplus by encouraging money to flow out of the country, may not always be the best course of action and depends on the country's economic goals and import needs. Borrowing from abroad is generally not necessary when the country has a surplus. Devaluing the currency is certainly not favorable in the context of a surplus as it can create inflationary pressures and reduce purchasing power internationally.

The United Nations Conference on Trade and Development (UNCTAD) is a UN body that focuses on trade and development issues, particularly those affecting developing countries. One of the functions of UNCTAD is to facilitate the transfer of technology from developed to less developed countries. This involves promoting the dissemination and adoption of technology in less developed countries to enhance their productive capacities, economic growth, and development.
UNCTAD recognizes that technology plays a crucial role in bridging the development gap between countries. By facilitating the transfer of technology, UNCTAD aims to enable developing countries to access and utilize advanced knowledge, skills, and technological innovations available in developed countries. This transfer of technology can occur through various means such as technical assistance, capacity building, knowledge sharing, and promoting partnerships between developed and developing countries.

The bank that is primarily dedicated to financing projects aimed at promoting economic and social development within the African continent is the African Development Bank (AfDB).

The African Development Bank (AfDB) was established in 1964 with the main objective to reduce poverty, improve living conditions, and promote economic and social development in African countries. It achieves these goals by providing loans and grants for a variety of development projects and programs across the continent. These projects cover various sectors including infrastructure, education, healthcare, agriculture, and energy.

Unlike purely commercial banks, the AfDB is focused on development projects that may not always have immediate financial returns but are crucial for the sustainable growth and development of African nations. The bank works together with member countries and international partners to mobilize resources and expertise needed to tackle the continent's challenges, often adopting innovative financing solutions tailored to the unique needs of the African context.

The equilibrium price in economics is a fundamental concept where the market operates most efficiently. To understand it fully, consider the following explanation:

When demand equates supply, it indicates the price at which the quantity of goods consumers are willing to buy (demand) is exactly equal to the quantity of goods producers are willing to sell (supply). This is the point where the market reaches equilibrium. At this price, there is no excess supply or demand, meaning that resources are being used most effectively, and there is no pressure on the price to change.

In contrast:

• If the price equals demand only, this would imply a scenario that doesn't exist in standard economic terms because equilibrium involves both supply and demand.
• When demand is less than supply, it suggests a surplus in the market, leading to downward pressure on price as sellers attempt to clear excess stock.
• If demand is greater than supply, it leads to a shortage, resulting in upward pressure on prices as consumers compete to buy the limited available goods.

Thus, at equilibrium price, demand equates supply, ensuring the market operates smoothly without surplus or shortage.

In a capitalist economic system, several features define its characteristics. To understand which of the given options is NOT a feature of capitalism, let's examine each one:

Free Enterprise: This is a fundamental aspect of capitalism. It refers to the freedom of businesses to operate competitively for profit with minimal government intervention. Under free enterprise, individuals and businesses have the right to sell goods and services, decide on investments, and set prices.

Private Ownership of Property: Another core feature of capitalism is the ownership of property by individuals or corporations rather than by the government. In this system, individuals have the right to own assets, resources, and production facilities. They can use, rent, or sell property as they see fit.

Competition: Competition is a driving force in capitalism. It encourages businesses to improve their products and services, enhance efficiency, lower prices, and innovate. Healthy competition is believed to lead to better choices and quality for consumers.

Detailed Economic Planning: This is NOT a feature of capitalism. Detailed economic planning is more characteristic of socialist or centrally planned economies where government agencies set production targets, control resources, and address distribution centrally. Capitalism relies more on market forces and price mechanisms to guide economic decisions rather than detailed and centralized planning.

Therefore, detailed economic planning is the correct answer as it is NOT a feature of capitalism.

Holding money to take care of contingencies is known as the precautionary motive.

Let me explain this further in a simple way:

• Imagine you keep aside some money for unexpected events, such as medical emergencies, car repairs, or other sudden expenses that might occur. This act of saving money for unforeseen needs is called the precautionary motive.
• The main purpose here is to have money on hand to tackle emergencies or any sudden need without having to struggle or sell other assets quickly.
• This behavior is different from having money for regular expenses, which is known as the transactions motive, where the money is kept for day-to-day spending like groceries and bills.
• It is also different from speculative motive, where money is held to take advantage of future investment opportunities.
• Lastly, expansionary motive typically relates to policy measures encouraging broader economic growth and isn't directly about individual money-holding behavior for emergencies.

When measuring national income using the **Income Approach**, the focus is on summing up all the **incomes earned** by individuals and businesses in an economy for providing goods and services. This typically includes wages, profits, rents, and interest received. Let's examine each option:

• **Profit earned by NITEL plc**: This is included because it is part of the profits earned by businesses.
• **Profit earned by Nigerian Bottling Company plc**: This is included for the same reason as above; it is business profit, which is a component of national income.
• **Income earned by a bricklayer**: This is included because it's a wage or salary, which is a fundamental part of national income.
• **Allowance given to an aged mother by a civil servant**: This is **NOT included** in measuring national income through the income approach. The reason is that these are private transfer payments or personal transfers, not payments made for labor, production of goods, or capital services.

Competitive demand refers to a situation where two or more goods are seen as substitutes for each other. When the pric of one commodity increases, consumers tend to shift their demand towards the substitute commodity, resulting in a decrease in the demand for the original commodity.
For example, if the price of coffee increases significantly, some consumers may choose to switch to tea as a substitute. A: a result, the demand for coffee decreases while the demand for tea increases.

To find the median of a set of numbers, the first step is to arrange the numbers in ascending order (from smallest to largest).

The given numbers are: 14, 13, 29, 15, 13, 17, 12.

Arrange them in ascending order: 12, 13, 13, 14, 15, 17, 29.

The median is the number that appears in the middle of this ordered list. Since there are 7 numbers in this list, the middle number is the fourth one.

In the ordered sequence 12, 13, 13, 14, 15, 17, 29, the median is 14.

The system of farming that involves the use of a large hectare of land planted with economic crops is known as plantation farming.

Explanation: Plantation farming is an agricultural system where a single crop is grown extensively over a large area. This system is specifically designed for the cultivation of high-demand crops, often termed as "economic crops," because they are produced for their commercial value rather than for direct consumption by the farmers. Such crops include coffee, tea, rubber, sugarcane, cotton, and palm oil.

Key Characteristics of Plantation Farming:

• Large-scale production: Plantation farms occupy vast expanses of land to maximize the output of a single type of crop.
• Monoculture: Typically, a single crop is cultivated, allowing specialization and efficiency in farming practices.
• Commercial orientation: The primary goal is to produce crops for sale, often aiming at international markets.
• Use of advanced techniques: Plantation farming often employs modern agricultural techniques, such as mechanization, irrigation, and the use of fertilizers and pesticides, to enhance productivity.
• Capital intensive: There is a significant investment in both infrastructure and labor to manage the large scale of operations.

In contrast, smaller or subsistence farmers often engage in diverse cropping systems with multiple types of plants cultivated for personal or local consumption. Plantation farming, on the other hand, is designed to produce large quantities of a specific, economically valuable crop to meet regional or global demands.

Localization of industries, also known as industrial clustering or agglomeration, refers to the concentration of similar industries or related businesses in a specific geographic area. While there are various advantages associated with localization, such as promoting knowledge spillovers, fostering collaboration, and enhancing economies of scale, it can also have disadvantages.
One of the disadvantages is the creation of structural unemployment. When industries concentrate in a particular region job opportunities may become limited to that specific area. As a result, workers in other regions or industries may face challenges in finding employment, leading to structural unemployment. This can be particularly problematic if the localized industry experiences a decline or faces disruptions, resulting in job losses for a significant portion of the workforce.

The act of cultivating land and rearing of animals for man's use is known as agriculture.

Agriculture is an activity that involves growing crops and raising animals to provide food, fiber, medicinal plants, and other products used to sustain and enhance human life. It is a vital practice that has been developed over thousands of years, allowing civilizations to flourish by ensuring a stable supply of food and resources. This practice not only involves the cultivation of the land for crops but also includes various other activities such as animal husbandry, which is the breeding and care of farm animals.

Let me explain a bit about the other terms you mentioned:

• Forestry refers to the management and conservation of forests and woodlands. It involves the planting, maintaining, and caring for trees and forests. While it might also involve the cultivation of certain types of land, its primary focus is on trees rather than a wide range of crops or livestock.
• Mono culture is a term used to describe the cultivation of a single crop in a given area, year after year. This is a method within agriculture but does not encompass the full scope of agriculture, which includes diversity in crop and animal production.
• Horticulture is a branch of agriculture that focuses on the cultivation of plants, fruits, vegetables, flowers, and ornamental plants. It deals mainly with garden crops rather than large-scale agricultural crops and usually doesn't focus on animal rearing.

Thus, the most comprehensive term that covers both the cultivation of land and rearing of animals is agriculture.

A persistent fall in the general price level is known as deflation.

To understand this better, let's break it down:

• General Price Level: This refers to the average of current prices across the entire spectrum of goods and services produced in the economy. It is like taking a snapshot of what prices look like overall in the economy.


• Deflation: This is the term used when the general price level is consistently decreasing over time. In simpler terms, it means that prices of goods and services are falling, making them cheaper for consumers. This might sound beneficial to consumers initially, but prolonged deflation can lead to reduced consumer spending, as people may delay purchases in anticipation of even lower prices. This can subsequently slow down economic growth and potentially lead to an economic recession.

Hence, when we say "persistent fall in the general price level," we are accurately describing deflation.

Opportunity cost is a key concept in economics that refers to the value of the next best alternative forgone when making a choice. It plays a significant role in determining the downward shift in the production possibilities curve (PPC).
The PPC represents the different combinations of two goods or services that an economy can produce given its limited resources and technology. It illustrates the trade-offs that occur when resources are allocated between the production o different goods.
When there is a downward shift or inward shift in the PPC, it indicates a decrease in the economy's productive capacity. This shift can be influenced by several factors, including changes in resource availability, technology, or the efficiency of resource allocation. However, opportunity cost can help explain how these factors lead to a downward shift.

If the price of commodity X increases and consumers start purchasing commodity Y instead, then commodities X and Y are considered substitutes. Substitutes are goods that can be used in place of one another; when the price of one goes up, consumers naturally shift their demand to the other because it serves a similar function or purpose.
Consider an example: if the price of coffee goes up, people might start drinking tea instead if tea serves as a similar alternative for their morning beverage needs. In this scenario, coffee and tea are substitutes. Therefore, the relationship between these goods is defined by consumers' ability to consider one in place of the other based on price.
In summary, when consumers replace their consumption of one good with another due to price change, the goods in question are substitutes.

In income determination theory, the acceleration principle suggests that investment is the primary driver or cause, whil income is the resulting effect. The acceleration principle states that changes in investment levels lead to amplified or accelerated changes in income.
The acceleration principle posits that changes in investment levels have a multiplier effect on income. When investment increases, it leads to increased production, employment, and income generation.

A producer who can influence the price of a product but cannot determine the quantity to be sold is best described as a monopolist.

Here's an explanation:

In a monopoly, there is only one producer or seller who dominates the entire market for a particular product or service. This producer has the power to influence the price because they are the sole supplier, and there are no close substitutes. However, while they can set the price based on their objectives, the actual quantity sold is determined by the market demand at that specific price.

The other terms are different:

• Duopoly refers to a market structure where there are two dominant producers. Here, each producer needs to consider the other's actions before setting prices or quantities.
• Monopsonist is a scenario where there is only one buyer, not one seller.
• Oligopoly refers to a market structure where a small number of firms have significant control. Firms in an oligopoly influence prices but must consider the reactions of other firms.

In developing countries, the largest component of national income typically consists of wages and salaries. This means that the income earned by individuals from their employment or labor work forms a significant part of the national income. Several reasons contribute to this:

• Labor-Intensive Economy: Developing countries often have labor-intensive sectors such as agriculture, manufacturing, and services, which employ a large number of people. These sectors need a substantial workforce, leading to the major share of national income coming from wages and salaries.
• Lower Levels of Capital: Capital refers to tools, equipment, and machinery used in production. Developing countries may have lower levels of capital investment, focusing more on labor to boost production, which again increases the share of wages and salaries in national income.
• Demographics: Developing countries often have younger populations with a high dependency on labor for earning income. This means most people derive their livelihood through working jobs rather than owning businesses or properties, leading to wages and salaries dominating national income.

In contrast, components like rent and profit tend to form a smaller component of national income in developing economies. While these components are important, they are usually not as predominant as wages and salaries due to the lesser commercialization and capital-intensive industries compared to developed countries.

The level of consumption generally refers to the amount of goods and services that households are willing and able to purchase. This can be influenced by several factors:

Level of Income: The more income people earn, the more they can spend on goods and services, which directly affects consumption levels. With higher income, households typically increase their consumption.

The Rate of Taxes Paid: Taxes directly impact disposable income, which is the income available after tax deductions. Higher taxes reduce disposable income and may lead to lower consumption, while lower taxes increase disposable income and can potentially boost consumption.

Savings: When households allocate a portion of their income to savings, this reduces the immediate level of consumption. Therefore, high levels of savings can indicate lower levels of consumption.

The Political Climate: Although the political climate can affect the economy in various ways, it is generally not a direct and immediate determinant of consumption levels. The political climate can influence factors like economic stability and government policies, but it is not a direct factor in determining how much households consume.

Based on these explanations, the factor that determines the level of consumption the least is the political climate, because its effects are indirect and less immediate compared to the direct effects of income, taxes, and savings on consumption.

When a government has its revenue receipts less than the expenditure in a fiscal year, the country is experiencing a deficit budget. Here's a simple explanation:

Revenue receipts are the funds government receives, mainly from taxes and other sources like fees, interests, etc.

Expenditure refers to the total amount of money the government spends on various needs like infrastructure, education, defense, welfare programs, and salaries.

If the money received (revenue receipts) is less than the money spent (expenditure), it indicates that the government is spending more than it is earning. This excess expenditure generates a gap which is known as a deficit.

To address this deficit, governments might need to borrow money or reduce spending to balance their finances in the future. Hence, when expenditure surpasses revenue, it results in a deficit budget.

The most prominent contribution of petroleum to the Nigerian economy is in the area of revenue generation.

Here’s why:

1. Major Source of Government Revenue: The petroleum industry is the backbone of Nigeria's economy, significantly impacting the nation’s fiscal landscape. It contributes a substantial portion of government revenue through the sale of crude oil globally. This revenue is critical for funding various government activities and programs.

2. Foreign Exchange Earnings: Crude oil and natural gas exports are a primary source of foreign exchange earnings for Nigeria. These earnings are vital as they enable the country to engage in international trade, import goods, and services, and stabilize the national currency.

3. Budgetary Funding: The Nigerian annual budget heavily relies on oil revenues. Oil sales provide the funds necessary for the government to execute national projects, maintain public services, and drive economic policies.

In summary, while petroleum impacts Nigeria's economy in various ways such as infrastructure development and employment generation, its contribution to revenue generation is by far the most prominent and crucial for sustaining government functions and the overall economic health of the nation.

An exceptional demand curve occurs when demand does not follow the typical downward slope from left to right. Instead, the demand curve may slope upward. Let’s consider some scenarios that could lead to this unusual situation.

Increase in Price of Raw Materials: This typically affects the supply side rather than the demand side. When prices of raw materials increase, production costs go up, possibly reducing supply, but not necessarily impacting demand directly. Therefore, this is not usually a reason for an exceptional demand curve.

Change in Taste of Consumer: If consumers suddenly prefer a particular product, they may be willing to buy more even if the price rises. This shift in consumer preferences can lead to an upward-sloping demand curve, reflecting increased demand despite higher prices.

Increase in the Size of the Population: More people can lead to higher overall demand, but each individual’s demand curve typically still slopes downward due to the law of diminishing marginal utility. Therefore, population increase alone generally does not cause an exceptional demand curve.

Expectation of Future Price Increase: When consumers expect prices to rise in the future, they may choose to buy more now to avoid paying higher prices later. This situation can lead to an upward-sloping demand curve as current demand increases with rising prices, due to future price expectations.

In summary, an exceptional demand curve is usually caused by changes in consumer tastes or expectations of future price increases, making current demand behave in an unexpected way compared to the usual downward slope.

Factors of production are the inputs used to produce goods and services in an economy. The main factors of production include land, labor, capital, and entrepreneurship. Each of these factors receives a specific reward or return:

• Land: The reward for using land as a factor of production is rent. Rent is the payment made for the use of land or real estate resources.
• Labor: The reward for labor is typically in the form of wages or salaries. It represents the compensation paid to workers for their productive efforts.
• Capital: The reward for capital, which includes machinery, tools, or financial capital used in production, is interest. It is the return on investment for using capital resources.
• Entrepreneurship: The reward for entrepreneurship, which involves the risk-taking and organization of other factors of production, is profit. Profit is the financial gain realized by entrepreneurs for their ventures.

The term subsidy is generally not a reward for factors of production. A subsidy is a financial assistance granted by the government to individuals or businesses to support activities, promote economic growth, or reduce the cost of certain goods and services. It is not directly linked to any of the classical factors of production.

In conclusion, while profit, rent, and interest are returns directly associated with factors of production, a subsidy is not. It serves a different purpose in economic policy.

The balance of payments is a record of all financial transactions made between consumers, businesses, and the government in one country with others. It includes trade in goods and services, investments, and money transfers. To improve a country's balance of payments, particularly the trade balance, countries may implement certain policies.

Anti-dumping policies are used to prevent foreign companies from selling goods at a price lower than their market value to gain an unfair advantage. By implementing anti-dumping policies, a country can protect its domestic industries from unfair competition, which can help improve the balance of payments by reducing imports or encouraging domestic consumption.

Granting subsidies to export producers can help improve the balance of payments by making domestic products cheaper and more competitive in international markets. By lowering production costs, subsidies can help increase exports, leading to an improvement in the balance of payments.

Increasing import duties is another way to improve the balance of payments. By imposing higher taxes on imported goods, a country can discourage imports and encourage consumers to purchase domestically produced goods. This can improve the trade balance by reducing the outflow of money used to purchase foreign products.

On the other hand, decreasing taxation on personal income doesn't directly affect the balance of payments. Reducing personal income tax may increase disposable income for consumers, which could lead to more consumption. However, this increased consumption might not necessarily focus on domestic goods, and could instead lead to higher imports. Therefore, among the options listed, decreasing taxation on personal income is the one least likely to directly improve a country's balance of payments.

To determine how many students are in SSS, we first need to figure out how many students are in JSS. According to the problem, 60% of the school's population is in JSS.

Here's a simple breakdown:

• The total population of the school is 600.
• 60% of 600 is calculated by multiplying 600 by 0.60. Mathematically, this is:
• 600 x 0.60 = 360. So, there are 360 students in JSS.

Since the whole school has 600 students, and 360 of those are in JSS, we can find out how many are in SSS by subtracting the JSS students from the total number of students:

600 - 360 = 240

Hence, there are 240 students in SSS.

Economic planning is an important policy tool used by governments to coordinate their efforts in improving the nation's economy. Let's look at the objectives:

Equitable allocation of resources: This is indeed an objective of economic planning. It ensures that resources are distributed evenly across different sectors and regions to promote balanced development and reduce regional disparities.

Achieving economic growth: Another key objective of economic planning is to spur economic growth. This involves increasing the capacity of the economy to produce goods and services, enhancing the standard of living, and elevating the overall wealth of the nation.

Creating employment: Economic planning aims to create jobs for the population. By fostering industries and fostering investment, economic planning attempts to reduce unemployment rates and provide more job opportunities.

Widening the income gap: This is NOT an objective of economic planning. Economic plans generally aim to reduce, not widen, the income gap between different segments of society. A widening income gap can lead to increased poverty and social unrest, which are contrary to the goals of economic planning focused on promoting equality and social harmony.

The expenditure approach is a common method used to calculate the national income, specifically the Gross Domestic Product (GDP) of a country. This approach sums up all expenditures or spending in the economy.

The correct formula for the expenditure approach is: Y = C + I + G + (X - M), where:

• C stands for Consumption: This is the total value of all goods and services consumed by households within the economy. It includes expenditures on items such as food, clothing, housing, and other personal expenses.
• I stands for Investment: This includes spending on capital goods that will be used to produce other goods and services in the future, such as machinery, buildings, and inventory.
• G stands for Government Spending: This is the total expenditure by the government on goods and services, including public sector salaries, defense, education, and infrastructure projects.
• (X - M) stands for Net Exports: This is calculated as total exports (X) minus total imports (M). Exports are goods and services sold to other countries, while imports are those bought from other countries. By subtracting imports from exports, we determine the net trade effect on the economy.

Putting it all together, this formula helps to calculate the total economic activity within a country by summing up consumption, investment, government spending, and net exports, giving a comprehensive picture of the national income.

To determine which option will NOT bring about an increase in the labor force, let's examine the impact of each one:

1. **Decrease in death rate:** When the death rate decreases, more people are living longer, which means that they remain available to be a part of the workforce. Thus, this can contribute to an increase in the labor force.

2. **Better medical services:** Improved medical services often lead to healthier individuals who can participate in work for longer durations. Good health can increase the number of individuals who can work and potentially extend their working life, thus leading to an increase in the labor force.

3. **Immigration:** Immigration allows people from other countries to enter and work in a new country. This directly increases the number of people who are available to work in that country, thereby increasing the labor force.

4. **Emigration:** Emigration is when people leave a country to work or live elsewhere. When individuals emigrate, they reduce the number of people available to work in the original country. Thus, **emigration** will NOT bring about an increase in the labor force; instead, it can contribute to a decrease.

In summary, the option that will NOT bring about an increase in the labor force is **Emigration**.

A price floor is a **minimum price** set by the government for a particular good or service. It is designed to ensure that the price is not too low, often supporting producers by maintaining their income at a viable level.

For a price floor to be effective, it is usually fixed **above the equilibrium price.** Here's why:

• **Equilibrium Price** is where the supply of a product equals the demand for that product. It is the point at which the market is said to be in balance.
• When a price floor is set **above the equilibrium**, it means that the price consumers are willing to pay is less than the price producers are willing to accept. This leads to a decrease in quantity demanded by consumers since the price is too high for them.
• Thus, producers end up with **more goods available than what consumers are buying**, creating a **surplus**. This surplus occurs because the set price is prohibiting the market from reaching its natural balance or equilibrium.

Therefore, a price floor is usually fixed **above the equilibrium and causes surpluses.** This allows it to serve its purpose of protecting producer revenues while potentially benefiting certain industry stakeholders.

Wholesalers play a significant role in the distribution of goods and services for several key reasons:

1. Bulk Purchasing and Distribution: Wholesalers buy large quantities of goods from producers and sell them in smaller lots to retailers, which allows them to benefit from economies of scale. This bulk buying helps keep costs low for retailers and ultimately consumers.

2. Bridging the Gap: By acting as an intermediary between producers and retailers, wholesalers play a crucial role in the supply chain. They enable manufacturers to focus on production while handling the complexities of distribution and logistics.

3. Financial Support: Wholesalers sometimes provide credit to retailers, allowing them to purchase goods and pay later. They also assist producers by buying inventory upfront, providing necessary funds for the producers to continue their business.

4. Information Exchange: Wholesalers gather market trends and feedback from retailers and share this information with producers. This helps producers adjust their products to meet consumer demands more effectively.

5. Inventory Management: Wholesalers manage storage and inventory, reducing the burden on manufacturers and retailers. They ensure a steady supply of products, minimizing the risk of stockouts or overproduction.

In summary, wholesalers are essential in the distribution network because they facilitate product flow, support financial operations, manage distribution logistics, and collect market intelligence.

To effectively compare the standard of living between Nigeria and Ghana, the most suitable method is through the use of per capita income. Let me explain why this is considered the best approach:

Per Capita Income is a measure that calculates the average income earned per person in a specific country or region in a given year. It is determined by dividing the country's total income by its population. This method provides a clear indicator of how much income, on average, each individual has, which gives insight into the general well-being and standard of living of the population.

Let's break it down further:

• Gross National Income: While it provides information about the total income of a country including foreign earnings, it does not account for distribution across the population. It may also include incomes that are not directly improving the local living standards.
• Net National Income: This takes into account depreciation but still does not efficiently measure what each individual is earning or living on.
• Net Disposable Income: This provides information about the income available to countries after taxes and transfers, yet doesn't offer a per-person analysis.

In contrast, per capita income specifically focuses on the income available to each person, thus offering a more direct reflection of the purchasing power and financial well-being of an individual within these countries. Therefore, when comparing the standard of living between Nigeria and Ghana, per capita income is a more practical and clearer measure.

Economics problems arise in all societies primarily because resources are not in adequate supply. This is known as the fundamental economic problem of scarcity. In every society, there are limited resources but unlimited wants and needs. These resources include things like land, labor, and capital, which are necessary for producing goods and services. Since we do not have enough of these resources to satisfy everyone's desires, we face choices about how to allocate them efficiently.

The issue of scarcity leads to other economic problems such as deciding what to produce, how to produce it, and for whom it should be produced. These decisions are made by assessing opportunity costs and considering how to make the best possible use of the limited resources available.

While factors such as lack of proper planning or mismanagement by leaders can exacerbate economic problems, they are not the root cause. The core issue remains the limited availability of resources, compelling societies to prioritize and decide how best to meet the needs of their population.

To understand the concept of marginal utility and price, let's delve into a simple explanation. Marginal utility refers to the additional satisfaction or utility that a consumer gains from consuming one more unit of a good or service. Meanwhile, the price of a commodity is what the consumer pays to acquire that good or service.

In economic terms, a consumer is said to be in equilibrium when they have allocated their resources in such a way that they get the most satisfaction or utility from their consumption. The consumer equilibrium condition is achieved when the marginal utility per unit of expenditure is the same for all commodities.

Therefore, when the marginal utility of a commodity is equal to its price, it means the consumer is maximizing their satisfaction with the resources available. The consumer has no incentive to change the consumption bundle because they are already getting the highest possible satisfaction. In other words, the consumer is getting just as much utility from the last unit of the good as it costs. Consequently, the consumer is in equilibrium.

Thus, the correct explanation is: The consumer is in equilibrium.

The Production Possibility Curve (PPC) is a graphical representation that shows the different combinations of two goods or services that an economy can produce, given certain assumptions like fixed resources and technology.

The trade-off between two commodities along the PPC primarily illustrates the opportunity cost principle. This principle refers to the idea that in order to produce more of one good, an economy must produce less of another good. The curve demonstrates this trade-off by showing that resources are limited, and choosing to allocate more resources to produce one commodity means reallocating those resources away from another commodity.

For example, if an economy is at a certain point on its PPC and decides to produce more of Commodity A, it will inevitably end up producing less of Commodity B. This reduction in the production of Commodity B is the opportunity cost of producing more of Commodity A. Hence, every point along the PPC illustrates the trade-off and opportunity cost of choosing different production levels of the two goods.

In the long-run equilibrium position for a firm, **all costs are variable**. This is because the long-run is a period sufficiently long for firms to adjust all factors of production. They can expand or reduce their capacity, acquire new technology, or even enter and exit industries depending on market conditions.

Unlike in the short-run where some factors (like buildings and machinery) are **fixed** because they cannot be changed immediately, in the long-run, firms have the flexibility to alter all their inputs. This means that firms can choose the optimal scale of operation where the average cost of production is minimized, leading to a position where profits are maximized if the market structure allows.

So, in summary: In the long-run, a firm operates where **all costs are variable**, allowing complete adjustment to maximize efficiency and competitive position in the market.
