The following can be used to improve a country's balance of payment EXCEPT
Detalhes da Resposta
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.

An industry engaged in the extraction of raw materials and its conversion into semi-finished goods is called industry.
Detalhes da Resposta
Processing involves transforming raw materials or inputs into more refined or semi-finished products. This can include various stages of production, such as refining, manufacturing, assembly, or other forms of processing.
The processing industry plays a vital role in taking raw materials from their natural state and converting them into products that can be used for further processing or consumed by end-users. This industry typically adds value to the rav materials by applying different processes, technologies, and expertise.
NOTE: Although manufacturing is involved in the production of goods, it does not specifically address the extraction of raw materials. Manufacturing encompasses a broader range of industries involved in producing finished goods from raw materials, components, or parts.

In the equation Q = a - bp + e; Q and P are ... Variables respectively.
Detalhes da Resposta
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:
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 comparison of the standard of living between Nigeria and Ghana is best down through the use of
Detalhes da Resposta
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:
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.

Wholesalers play an important in the distribution of goods and services because they
Detalhes da Resposta
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.

The following are problems of development planning in Nigeria EXCEPT
Detalhes da Resposta
Nigeria, like many developing countries, faces several challenges in its development planning. These include issues such as inadequate capital, which limits the ability to fund critical development projects and infrastructure, thus hindering economic growth. Another significant challenge is the inadequate statistical data, which affects the ability to make informed, evidence-based policy decisions. Without reliable data, it's difficult to plan effectively and measure progress.
Poor implementation of economic planning is also a notable problem, as even the best-laid plans cannot yield results if not properly executed. This might be due to bureaucratic inefficiencies, corruption, or lack of capacity.
However, the statement under-population is not a commonly recognized problem in Nigeria. In fact, Nigeria is known for having a large and rapidly growing population, which sometimes poses its own challenges in terms of resource management and service provision. Therefore, the issue of under-population can be seen as an exception to the typical problems of development planning in Nigeria.

The following determine the level of consumption EXCEPT
Detalhes da Resposta
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.

What add funds to the circular flow?
Detalhes da Resposta
The concept of the circular flow of income represents how money moves within an economy among consumers, businesses, and various markets. In this circular flow, three key elements can either add to or reduce the flow of funds: **leakages** and **injections**.
Leakages are the flows of money that exit the circular flow. They reduce the amount of money that circulates within the economy. Common leakages include savings, taxes, and imports. For instance, when individuals save money instead of spending it, that money is not used to purchase goods or services, thus exiting the circular flow.
Injections, on the other hand, are the activities or financial inflows that add funds to the circular flow of income, ensuring continued economic activity. They increase the total amount of money circulating in the economy. These include investment, government spending, and exports.
The expenditure approach is a method for calculating a nation's Gross Domestic Product (GDP) by considering the total expenditure on the nation's final output of goods and services in a year. While this approach helps to measure the size of the economy, it is not directly responsible for adding funds to the circular flow. Instead, it relies on the activities of consumption, investment, government spending, and net exports.
In conclusion, it is the concept of injection that directly adds funds to the circular flow, stimulating economic activities and growth by multiplying the effects of initial spending through the economy.
Pergunta 12 Relatório
Which of the following is NOT a factor that brings about changes in demand?
Detalhes da Resposta
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.

Stock exchange market deals with
Detalhes da Resposta
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.

Which of the following is NOT a feature of capitalism?
Detalhes da Resposta
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.

Which of the following is a disadvantage of localization of industries?
Detalhes da Resposta
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.
Pergunta 17 Relatório
Which of the following is NOT an objective of Economic planning?
Detalhes da Resposta
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.

Detalhes da Resposta
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.
Pergunta 19 Relatório
The diagram belwo, shows the relationship between
Detalhes da Resposta
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.

Pergunta 21 Relatório
The following will occur when maximum price is fixed below the free market price EXCEPT that
Detalhes da Resposta
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.

Detalhes da Resposta
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:
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.

Which of the following is NOT associated with minimum price legislation?
Detalhes da Resposta
Minimum price legislation is a policy where the government sets a lower price limit for certain goods or services, meaning they cannot be sold below this set price. It is often intended to protect producers, ensuring they receive fair compensation and maintaining industry standards.
When a minimum price is set above the equilibrium price, it typically leads to several economic effects:
Excess demand is NOT associated with minimum price legislation. Excess demand occurs when the price is set too low, leading to a situation where the quantity demanded exceeds the quantity supplied. This situation is commonly related to maximum price controls, not minimum price legislation.

Detalhes da Resposta
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.

Under perfect competition, a profit-maximizing firm will hire labor up to the point where the marginal revenue product of labor (MRP) is equal to the wage rate. MRP represents the additional revenue generated by adding one more unit of labor.
Since the firm aims to maximize profits, it will continue hiring labor until the MRP is greater than or equal to the wage rate. At this point, the last unit of labor hired contributes more to total revenue than to total cost, resulting in increased profits for the firm.

Economics problems arise in all societies because
Detalhes da Resposta
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.

If the standard deviation of a set of numbers is 3.6, what is the variance?
Detalhes da Resposta
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**.

Detalhes da Resposta
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.

At the equilibrium price,
Detalhes da Resposta
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:
Thus, at equilibrium price, demand equates supply, ensuring the market operates smoothly without surplus or shortage.

Detalhes da Resposta
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.
