An industry operating in a perfect competitive market situation will maximum profit when

Detalles de la respuesta

In a perfectly competitive market, an industry or firm will maximize its profit when its Marginal Cost (MC) equals Marginal Revenue (MR). This is a fundamental principle of microeconomics that ensures the firm's resources are being used most efficiently.

Here's why:

• Marginal Cost (MC) is the additional cost incurred from producing one more unit of a good or service.
• Marginal Revenue (MR) is the additional revenue generated from selling one more unit of a good or service.

If MC = MR, the cost of producing an additional unit is exactly equal to the revenue it generates, meaning any increase or decrease in production would not improve profitability. At this point, the firm is efficiently allocating its resources.

If MC < MR; it means that the cost of producing an extra unit is less than the revenue it brings. The firm can increase its profit by producing and selling more units.

Conversely, if MC > MR; the cost of producing an extra unit exceeds the revenue it brings, and the firm should reduce production to avoid losses.

Therefore, to achieve maximum profit, a firm in a perfectly competitive market should continue adjusting its output until the cost of the last unit produced is exactly equal to the revenue it produces, which occurs at MC = MR.

A major characteristics of a firm operating at a long-run equilibrium position is that

Detalles de la respuesta

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.

MPC + MPS equals

Detalles de la respuesta

The terms MPC and MPS are concepts from economics that describe how households make spending and saving decisions out of their income. Let's break these down for a better understanding:

• MPC (Marginal Propensity to Consume): This represents the portion of additional income that a household is likely to spend on consumption rather than saving. For example, if someone's income increases by $100 and they spend $80 of that increase, their MPC would be 0.8 (80/100).
• MPS (Marginal Propensity to Save): Conversely, this is the portion of additional income that a household is likely to save rather than spend. Continuing the previous example, if the household saves $20 out of the $100 increase in income, their MPS would be 0.2 (20/100).

The sum of MPC and MPS must equal 1 because the additional income can only be spent or saved, meaning there aren’t any other alternatives for allocating this extra income. Therefore, mathematically, we express it as:

MPC + MPS = 1

In a closed economy model, the whole of any extra income is divided into consumption and saving, thereby making 1 the correct answer. So, whenever income changes, whatever portion is not spent (MPC) is saved (MPS), summing it up to one.

At the equilibrium price,

Detalles de la respuesta

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.

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

Detalles de la respuesta

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 following can be used to improve a country's balance of payment EXCEPT

Detalles de la respuesta

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.

The diagram below represent

Detalles de la respuesta

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.

Which of the following is NOT a function of marketing boards in Nigeria?

Detalles de la respuesta

In Nigeria, marketing boards were established to regulate and promote agricultural products. Their primary functions include activities like grading farm produce to ensure quality standards and marketing farm produce by finding markets where these products can be sold. They are also responsible for fixing prices for farm produce to stabilize farmers' incomes and protect them from market fluctuations.

However, one activity that marketing boards do not typically perform is the importation of farm produce. Marketing boards are mainly concerned with the domestic production and distribution of local agricultural products, whereas the importation would fall under international trade domains and different regulatory agencies. Thus, the importation of farm produce is not a usual function of marketing boards in Nigeria.

When an economy is having a balance of payment surplus the best alternative opened to it is to

Detalles de la respuesta

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 comparison of the standard of living between Nigeria and Ghana is best down through the use of

Detalles de la respuesta

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.

The act of cultivating land and rearing of animal for man's use is

Detalles de la respuesta

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.

In the equation Q = a - bp + e; Q and P are ... Variables respectively.

Detalles de la respuesta

In the given equation Q = a - bp + e, we need to understand the roles of the variables Q and P.

In any equation where we are trying to establish a relationship between two variables, one of the variables is usually controlled or changed deliberately, while the other one is observed as it changes in response. In such equations:

• The **independent variable** is the one that you control or change to see how it affects another variable. It is like the **cause** or **input**.
• The **dependent variable** is the one that changes as a result of the changes in the independent variable. It is like the **effect** or **output**.

In the equation Q = a - bp + e, **Q** is the outcome or result that we observe, and it depends on the value of **P**. Thus, **Q is the dependent variable** because it changes depending on the values of **P**. Conversely, **P** is the one that we can change or manipulate in the context of this equation, so **P is the independent variable**.

Therefore, the correct description for **Q** and **P** is that Q is the **dependent** variable, and P is the **independent** variable.

The demand for factors of production is said to be

Detalles de la respuesta

In economics, the demand for factors of production is best described as being derived. What this means is that the demand for these factors, like labor, land, and capital, is not for their own sake but because of the demand for the goods and services they can produce.

To put it simply, businesses need these factors of production to create products. If there is a high demand for a particular product, there will naturally be a higher demand for the factors needed to produce that product. Conversely, if there is little to no demand for a product, then the demand for the factors required to produce it will also decrease.

For example, if there is a high demand for cars, a car manufacturing company will need more metal, labor, and machinery, which are the factors of production, to make more cars. Thus, the demand for these factors is based on, or derived from, the demand for the cars themselves.

When an increase in the price of a commodity lead to a fall In the demand for another, the demand for the two commodities are said to be

Detalles de la respuesta

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.

The revolution of Cassava from ordinary food crop to export crop will lead to

Detalles de la respuesta

The recent revolution of cassava from an ordinary food crop to an export crop is likely to lead to an increase in the price of cassava products.
When cassava transitions from being primarily used as a food crop to an export crop, its demand and value in the international market tend to increase. This increased demand can result in higher prices for cassava products such as cassava flour, starch, or other processed derivatives.

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

Detalles de la respuesta

In the long run, a firm's average cost decreases primarily because of increasing returns to scale. This occurs when a firm's output increases by a proportion greater than the increase in inputs. In simpler terms, when a company gets bigger, it becomes more efficient at production. Consider the following reasons:

• **Economies of Scale**: As production scales up, certain costs such as fixed costs are spread over a larger number of goods, thus reducing the cost per unit.
• **Specialization and Division of Labor**: Larger firms often permit more specialization among workers and use more advanced technology, leading to increased productivity.
• **Bulk Purchasing**: Bigger firms can buy raw materials in large quantities at a discounted rate, which reduces the cost of production per unit.

Other options, like **diminishing average returns** or **decreasing marginal returns**, generally pertain to situations in the short run or under different conditions and would not directly explain a decrease in average costs in the long run. Additionally, while **decreasing average fixed cost** could reduce cost in the short run, in the long run, all costs are variable and focus instead shifts to how efficiently inputs are converted to outputs.

The diagram belwo, shows the relationship between

Detalles de la respuesta

The relationship shown in the diagram is most likely related to the **wage rate and unemployment.** Let me explain this relationship clearly:

The **wage rate** refers to the payment workers receive for their labor, typically expressed on an hourly, daily, or yearly basis. The **unemployment rate** is the percentage of the labor force that is jobless and actively looking for work.

When the **wage rate** offered in the market is above the equilibrium wage (where the supply of labor equals the demand for labor), firms may choose to hire fewer workers as it becomes more expensive to employ labor. This can lead to an **increase in unemployment**. Conversely, if the wage rate is lower, firms are more likely to hire additional workers, possibly decreasing unemployment.

Understanding this relationship is crucial in comprehending how wage policies can influence employment levels. Wage increases that are not aligned with productivity may result in higher costs for employers, potentially resulting in a reduction of jobs available, hence increasing unemployment. Therefore, there is a delicate balance between setting wage levels and maintaining employment levels in the economy.

If government in a fiscal year has its revenue receipts less than the expenditure, such country is having

Detalles de la respuesta

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.

Which of these is NOT associated with the problem of internal trade?

Detalles de la respuesta

Market trade unions are not typically associated with the problem of internal trade. Trade unions are typically formed b workers or employees to protect their rights, negotiate better working conditions, and advocate for their interests. While trade unions can have an impact on labor markets and industrial relations, they are not directly linked to the challenges or problems specifically related to internal trade.

A market situation with few sellers and many buyers is called

Detalles de la respuesta

The market situation you are referring to is called an oligopoly.

To put it simply, an oligopoly is a market structure where there are only a few sellers, or producers, who dominate the market, while there are many buyers. This creates a situation where the few sellers have significant control over the prices and market dynamics.

This structure is different from a perfect competition, where there are many sellers and buyers, with no single seller having significant market power. It is also different from a duopoly, which specifically refers to exactly two sellers.

The presence of a small number of sellers in an oligopoly leads to competitive strategies where the actions of one seller can influence the actions of others. This often results in strategic collaboration or competition, which affects prices and product offerings.

Stock exchange market deals with

Detalles de la respuesta

The stock exchange market primarily deals with the sales of second-hand securities. In this context, "second-hand securities" refer to financial instruments such as stocks and bonds that have already been issued by a company and are currently being traded among investors. When a company first issues stocks or bonds, it is done in the primary market. Once these securities are purchased and then resold by investors, they are traded in the secondary market, commonly known as the stock exchange.

Here's a simple rundown of how it works:

1. **Initial Offering:** A company looking to raise capital might issue stocks or bonds to investors. This takes place in the primary market through an Initial Public Offering (IPO) or similar mechanisms.

2. **Secondary Trading:** Once issued, these securities can be bought and sold on the stock exchange. Investors trade these securities based on supply and demand, trying to make a profit by buying low and selling high.

Therefore, the stock exchange acts as a platform where buyers and sellers meet to trade these second-hand securities. This buying and selling provide the liquidity required for the market to function efficiently and helps in price discovery of the securities based on market demand.

Persistent fall In the general price level is known as

Detalles de la respuesta

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.

Which of the following is NOT a function of the IMF?

Detalles de la respuesta

The International Monetary Fund (IMF) is an international organization that primarily focuses on ensuring the stability of the international monetary system. Here are some of its core functions:

• Providing financial aid to members experiencing balance of payment difficulties: The IMF provides financial assistance to countries facing balance of payment problems. This helps stabilize their economies and restore growth.
• Promoting international monetary cooperation: The IMF encourages international collaboration in monetary policies to sustain financial stability and growth across nations.
• Exchange rate stabilization: The IMF works with countries to help stabilize their exchange rates by providing policy advice and financial assistance, aiming to avoid competitive devaluations and maintain global economic equilibrium.

The statement that is NOT a function of the IMF is "assisting member countries in printing and issuing their currency." The IMF does not assist countries in printing or issuing their currency. This activity is typically managed by each country's own central bank or monetary authority. Thus, this function does not fall under the responsibilities of the IMF.

f the population of a school is 600 and 60% are In JSS, how many students are in SSS?

Detalles de la respuesta

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.

An exceptional demand curve can result from

Detalles de la respuesta

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.

If the price of commodity X rises and consumers shift to commodity Y, then commodities X and Y are

Detalles de la respuesta

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.

Which of the following is NOT a feature of capitalism?

Detalles de la respuesta

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.

If the standard deviation of a set of numbers is 3.6, what is the variance?

Detalles de la respuesta

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**.

The use of tax and expenditure policy to regulate the economy is known as

Detalles de la respuesta

The use of tax and expenditure policy to regulate the economy is known as fiscal policy.

Fiscal policy refers to the government's use of its spending levels and tax rates to influence a nation's economy. It is primarily the responsibility of the government to adjust its spending and tax rates to either promote economic growth or control inflation. By doing so, the government aims to achieve macroeconomic objectives such as controlling inflation, reducing unemployment, and achieving economic growth.

There are two main types of fiscal policy:

• Expansionary Fiscal Policy: This involves increasing government spending and/or decreasing taxes to stimulate economic growth. It is often used in times of recession or economic downturns to increase demand and reduce unemployment.
• Contractionary Fiscal Policy: This involves decreasing government spending and/or increasing taxes to cool down an overheated economy. It is employed to control inflation when the economy is growing too quickly.

In summary, fiscal policy is crucial because it directly impacts the economy by influencing the level of aggregate demand through changes in government spending and taxation.

From the diagram below, the equilibrium wage rate is

Detalles de la respuesta

The equilibrium wage rate is achieved when the demand for labour equals the supply of labour in a particular labour market. At this point, there is no excess demand or excess supply of labour, and the market is in balance.
From the diagram above, the equilibrium wage rate is W2.

The following will occur when maximum price is fixed below the free market price EXCEPT that

Detalles de la respuesta

When a maximum price is fixed below the free market price, it can lead to several outcomes due to the restrictions placed on how high a price can go. Here's a breakdown of what typically happens:


1. **Encouragement of Black Market:** When the price ceiling is lower than what would naturally occur, some sellers may not be willing to sell at the lower price. This may encourage them to sell illegally at higher prices, leading to the emergence of a **black market**.


2. **Excess Demand:** A lower price means that more people can afford the product. Therefore, demand for the product increases, but because producers are not willing to supply more at that low price (since they make less profit), there isn't enough product to meet demand. This creates **excess demand**. People want more of the product than is available.


3. **Excess Supply:** This situation is not a consequence of setting a maximum price below the free market price. **Excess supply** happens when the price is too high, resulting in goods remaining unsold as consumers are not willing to buy at that price. But since in this scenario, the price is kept low, the opposite happens: a shortage, not a surplus.


4. **Rationing of Commodities:** To manage the excess demand and ensure fair distribution since there's a shortage, the government or sellers may need to introduce **rationing**. This means setting limits on how much each individual can purchase to prevent the faster depletion of available goods.


In summary, the statement about **excess supply** is the one that would not occur when a maximum price is fixed below the free market level. Instead, you'll have excess demand. This discrepancy is because the artificially low price discourages producers from supplying more of the good.

If two bags of rice were sold for #1,250 a month ago and two weeks later, the same amount was used to procure one bag. This simply means that the value of money is

Detalles de la respuesta

In this scenario, the price of rice has increased relative to the amount of money (N1,250) that could be used to purchase it. Initially, N1,250 could buy two bags of rice, but after two weeks, the same amount can only buy one bag.
This decrease in purchasing power demonstrates that the value of money has declined. In other words, the same amount of money can now buy fewer goods or services than before. This situation is often referred to as inflation, where the general price level of goods and services rises over time, reducing the purchasing power of money.

Which of the following is a disadvantage of localization of industries?

Detalles de la respuesta

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.

Which of the following will NOT bring about an increase in Labour force?

Detalles de la respuesta

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**.

Which of the following is NOT a major role of OPEC in production, and marketing of petroleum?

Detalles de la respuesta

Refining of petroleum products in member countries is NOT a major role of OPEC in the production and marketing of petroleum.

Let me explain why:

• Stabilizing oil prices by putting a production ceiling: OPEC primarily works by coordinating and unifying the petroleum policies of its member countries. By setting production levels, it aims to stabilize the oil market to avoid excessive fluctuations in oil prices.
• Raising the revenue of member countries from oil through price increase: OPEC seeks to ensure that member countries receive fair and stable incomes from their petroleum resources. This often involves strategies to influence global oil prices.
• Ensuring efficient and regular supply of oil to the market: OPEC works to provide a reliable supply of oil to the global market, preventing shortages and ensuring that the supply meets demand.
• Refining of petroleum products in member countries: This is not a primary function of OPEC. While refining can occur within member countries, OPEC's core activities focus on the regulation of crude oil production and market stability rather than refining processes.

In summary, the main roles of OPEC include balancing oil production and prices and ensuring a steady supply, but they do not majorly focus on the refining of petroleum products.

The problem of "how to produce" in any economy is solved by

Detalles de la respuesta

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.

What is the median term in the distribution below; 14, 13 29,15,13,17,12.

Detalles de la respuesta

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.

Which of the following is NOT a factor that brings about changes in demand?

Detalles de la respuesta

In economics, a change in demand is influenced by several factors, but one of the options provided is NOT a factor that leads to a change in demand. This factor is the price of the good or service.

Here’s why:

The Price of the Good or Service: When we talk about demand, we focus on a demand curve that represents the relationship between the price of a good and the quantity demanded. A change in the price of the good itself does not shift the demand curve; instead, it results in a movement along the demand curve. Therefore, changes in the price of the good or service itself do not cause a change in demand but rather a change in the quantity demanded.

In contrast, the following factors do cause shifts in the demand curve (change in demand):

A Change in Real Income: When consumers have more or less income, their ability to purchase goods and services changes. If real income increases, consumers can afford to buy more, shifting the demand curve to the right. Conversely, a decrease in real income shifts the demand curve to the left.

Government Policy: Policies such as taxes, subsidies, regulations, or import restrictions can impact consumer purchasing power or the attractiveness of a product, influencing demand. For example, a subsidy on solar panels might increase their demand as they become more affordable.

Increase in Population: An increase in population typically increases demand for various goods and services as more people in the economy need these products, causing a rightward shift in the demand curve.

An economy in which decision of what to produce is taken partly by private individuals and state is referred to as Economy.

Detalles de la respuesta

An economy in which decisions about what to produce are taken partly by private individuals and partly by the state is referred to as a Mixed Economy.

In a Mixed Economy, there is a combination of both private sector and public sector involvement. This structure allows private individuals to own businesses and make decisions about what to produce based on market demands and profitability. At the same time, the government also plays a significant role in economic decision-making, often by regulating certain industries or directly providing goods and services. The balance between these two forces aims to combine the benefits of both market dynamism and government oversight.

Here's a brief explanation of other economic systems to provide contrast:

• Communist Economy: In a communist economy, the state owns and controls all means of production. Private ownership is minimal or nonexistent, and the government makes all decisions about what to produce and how to distribute resources.


• Socialist Economy: A socialist economy also involves significant government control, but there can be some level of private ownership. The government typically focuses on wealth distribution and providing basic services, aiming for social welfare and equality.


• Capitalist Economy: In a capitalist economy, private individuals and corporations own and manage all businesses. Decisions about production and distribution are made based on market forces and competition, with minimal government intervention.

In summary, a Mixed Economy represents a blend that includes elements of both market-driven and government-directed decisions, which sets it apart from other economic types.

Holding money to take care of contingencies is

Detalles de la respuesta

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.
