Question 2 Report
Which of the following is an indirect tax?
Answer Details
The option "excise duties" is an indirect tax.
An indirect tax is a tax that is not directly paid to the government by the person on whom it is imposed. Instead, it is collected by an intermediary, such as a manufacturer or a retailer, who then passes the tax on to the consumer by including it in the price of the goods or services they sell.
Excise duties are a form of indirect tax that is imposed on specific goods, such as alcohol, tobacco, gasoline, and luxury items. The duty is usually added to the price of the goods and paid by the manufacturers or importers of the products. The manufacturers or importers then pass the cost of the excise duty on to the consumer in the form of a higher price.
On the other hand, a poll tax is a tax that is directly paid by every adult member of a community, regardless of their income or wealth. Personal income tax is a direct tax that is paid by individuals on their income. Company tax is a direct tax that is paid by businesses on their profits.
In summary, an indirect tax is a tax that is collected by an intermediary and passed on to the consumer. Excise duties are a form of indirect tax imposed on specific goods, making it the correct answer in this case.
Question 3 Report

Question 8 Report
Given that the total production of Bandako farmers with one worker is
10kg. When the workers increased to 2, 3, and 4, the total production
increases to 20, 36 and 60kg respectively. Calculate the average product
(AP) of the 4th unit of labour.
Answer Details
The average product (AP) of the 4th unit of labor is 15kg. The average product is calculated by dividing the total output by the number of workers. In this case, the total output is 60kg and the number of workers is 4, so the average product is 60/4 = 15kg. This means that, on average, each additional worker contributes 15kg to the total production.
Question 9 Report
Localization of industry is encouraged because of ________

industries. When such industries are located, goods are made available
and the people get employment and earn income hence, their standard of
living will be improved
Question 10 Report
Which of the following is NOT a source of government revenue?
Answer Details
Personal income, disposable income, and transfer earnings are NOT sources of government revenue.
Government revenue refers to the money collected by the government to fund its operations and provide services to its citizens. It comes from various sources, including taxes, fees, licenses, fines, grants, aids, borrowing, interest, dividends, profits, and earnings.
Personal income, disposable income, and transfer earnings are all related to individuals' income and spending. Personal income is the amount of money an individual earns from all sources. Disposable income is the amount of money an individual has left after paying taxes. Transfer earnings refer to income received from government transfer payments, such as Social Security.
While the government may be interested in monitoring these types of income, they do not represent a direct source of revenue for the government. The government may use taxation policies to affect personal income and disposable income, but they do not directly collect them as revenue. Therefore, personal income, disposable income, and transfer earnings are NOT sources of government revenue.
Question 11 Report
A country's terms of trade can be improved by ____?
Answer Details
Tariffs are taxes or duties imposed on imports and exports by the
government of a country. The idea behind tariffs is to restrict the
volume of trade or improve the international terms of trade.
Question 12 Report
Which of the following budgets will increase government expenditure?
Answer Details
The budget that would increase government expenditure is a deficit budget.
A deficit budget is a budget where government expenditure exceeds its revenue or income. This means that the government will have to borrow money or take out loans to finance its expenses. This budget can be used to finance important projects such as infrastructure development, social welfare programs, or to stimulate economic growth.
On the other hand, a surplus budget is a budget where government revenue exceeds its expenditure. This type of budget is used to pay off debt, build up savings, or reduce taxes. A balanced budget policy is a budget where government expenditure is equal to its revenue, with no deficit or surplus.
Finally, a zero-based budget is a budgeting method where all expenses must be justified for each new period, as if no budget existed before. It is a way of reducing spending, rather than increasing it.
In summary, a deficit budget increases government expenditure, while a surplus budget reduces it.
Question 13 Report
The modal value of 3, 8, 4, 6, 3, 5, 2, 7, 3 and 5 is
Answer Details
To find the modal value of a set of numbers, we need to find the number that appears most frequently in the set.
In this case, the set of numbers is 3, 8, 4, 6, 3, 5, 2, 7, 3, and 5. To find the modal value, we need to count the frequency of each number in the set.
- The number 3 appears three times in the set.
- The number 8 appears once.
- The number 4 appears once.
- The number 6 appears once.
- The number 5 appears twice.
- The number 2 appears once.
- The number 7 appears once.
Since the number 3 appears most frequently in the set (three times), it is the modal value. Therefore, the answer is 3.
In summary, the modal value of a set of numbers is the number that appears most frequently in the set. In this case, the number 3 appears most frequently, so it is the modal value.
Question 14 Report
Which of the following is correct?
Answer Details
The correct statement is:
Traditional budgeting starts with last year's funding appropriation.
Traditional budgeting typically uses the previous year's budget as a starting point and then makes adjustments based on changes in circumstances or goals for the upcoming year. This process assumes that the previous year's spending was appropriate and does not necessarily consider all alternatives to current operations.
Zero-based budgeting, on the other hand, requires that all activities and expenses start from a zero base and must be justified for inclusion in the budget. This approach aims to reduce inefficiencies and identify unnecessary expenses by examining each line item and evaluating its necessity and value to the organization. Zero-based budgeting does not produce a single level of appropriation but rather evaluates each activity and expense individually to determine its priority and level of funding.
In summary, traditional budgeting is more focused on incremental changes and building upon the previous year's budget, while zero-based budgeting requires a more thorough examination of expenses and a justification for each line item in the budget.
Question 15 Report
Given a consumption function C = 10 + 0.6Y, determine the value of C if Y is 20
Answer Details
The consumption function C = 10 + 0.6Y relates the level of consumption (C) to the level of income (Y). If Y is 20, then we can substitute this value into the equation and solve for C:
C = 10 + 0.6Y
C = 10 + 0.6(20)
C = 10 + 12
C = 22
Therefore, the value of C if Y is 20 is 22.
This means that if the level of income (Y) is 20, then the level of consumption (C) would be 22. The consumption function shows that consumption increases with an increase in income. In this case, the consumption function suggests that for every one unit increase in income, consumption would increase by 0.6 units.
Question 16 Report
Excess supply over demand will place a price advantage on _____
Answer Details
This is because, according to the concept of equilibrium, if supply
increases while demand remains constant, there will be an excess of
supply over demand. This will bring about a decrease in the equilibrium
price of the commodity and an increase in the equilibrium quantity. This
gave rise to the fifth law of demand and supply which states that: “an
increase in the supply of a commodity will cause the equilibrium price
to fall and the quantity demanded to increase, while a decrease in
supply will cause the equilibrium price to rise but the quantity
demanded will fall”.
Question 17 Report
Cost - push inflation occurs when_______
Answer Details
Cost push inflation occurs when increase in cost of production are
passed on to consumers in the form of high price for the goods and
services on sale. The price of goods are pushed up by rising costs.

Question 19 Report

Answer Details
A completely competitive market exists when each member is a price taker.
In a competitive market, there are many buyers and sellers, none of whom can influence the market price on their own. In other words, each member of the market is a price taker, meaning they must accept the market price for the goods or services they are buying or selling.
Because no single buyer or seller has enough market power to set the price, the market price is determined solely by the interaction of supply and demand. In a completely competitive market, the goods or services being bought and sold are identical, so there is perfect substitutability between suppliers, and buyers will choose the lowest price available.
Overall, a completely competitive market is considered to be efficient, because it results in a fair and optimal allocation of resources, as each member is incentivized to produce and consume at the market-determined price.
Question 20 Report
One of the functions of the price system is that it
Answer Details
The price system is a mechanism through which prices of goods and services are determined by the forces of supply and demand. One of its primary functions is to regulate production and consumption in the economy.
As prices rise, it signals to producers that there is high demand for their products and they should produce more. This, in turn, encourages a higher volume of production, as producers aim to take advantage of the higher prices and generate greater profits. On the other hand, if prices fall, it signals to producers that there is low demand for their products, and they may scale back production.
Similarly, the price system also regulates consumption. When prices of certain goods or services are high, consumers tend to reduce their consumption of those products, while they may increase their consumption of substitutes that are relatively cheaper. For example, if gasoline prices rise, consumers may reduce their driving or switch to more fuel-efficient cars.
Therefore, the price system acts as a self-regulating mechanism that helps to allocate resources in the economy efficiently. It encourages the production of goods and services that are in high demand and discourages the production of goods and services that are in low demand, while also regulating consumption patterns.
Question 21 Report
When the government fix the price of essential commodities, this is referred to as:
Answer Details
When the government fixes the price of essential commodities, this is referred to as Price Control. This means that the government sets a specific price for certain goods, usually ones that are considered essential for everyday life such as food and medicine, and that price cannot be changed by market forces such as supply and demand. The government does this in order to ensure that these essential goods are affordable for everyone, especially those with low incomes. The goal of price control is to prevent prices from becoming too high, but it can also lead to shortages of the controlled goods if the fixed price is not high enough to cover the cost of producing them. In simple terms, price control is when the government sets the price for certain goods instead of letting the market determine the price.
Question 22 Report
The economic questions about what and how to produce in an economy is solely answered by the _______?
Answer Details
The economic questions about what and how to produce in an economy are answered by the system of economy practiced in that society.
The economic system is the way a society organizes the production, distribution, and consumption of goods and services. The decisions about what goods and services to produce, how to produce them, and for whom to produce them are influenced by the economic system in place.
For example, in a market economy, the decisions about what to produce, how to produce it, and for whom to produce it are mainly made by private enterprises in response to market demand. In a command economy, these decisions are made by the government. In a mixed economy, the decisions are made by both private enterprises and the government.
Therefore, the economic system in place plays a crucial role in answering the economic questions about what and how to produce in an economy.
Question 23 Report
One of the unique features that distinguishes the perfect and imperfect market condition is _________
Answer Details
The unique feature that distinguishes the perfect and imperfect market condition is the number of sellers and buyers.
In a perfect market, there are many buyers and sellers, and each one has only a small impact on the market price. This means that no single buyer or seller can control the price, and the market determines the price based on supply and demand.
On the other hand, in an imperfect market, there are either few sellers or few buyers, and one or a few of them can have a significant impact on the market price. This means that the price is not solely determined by supply and demand, but also by the actions of one or a few dominant players in the market.
This distinction is important because it affects the efficiency of the market and the distribution of economic benefits between buyers and sellers. In a perfect market, the market price reflects the true cost of production and distribution, and everyone gets a fair return for their efforts. In an imperfect market, the market price may not reflect the true cost, and some participants may receive a higher or lower return than they would in a perfect market.
Question 24 Report
Which modal of the factor is inelastic?
Answer Details
The factor of production that is typically considered inelastic is land.
In economics, the term "inelastic" refers to a situation where the quantity supplied or demanded of a good or service does not change much in response to changes in its price. In the case of land, the supply is generally considered to be fixed, meaning that the quantity of land available for use in a particular area is unlikely to change significantly in response to changes in its price.
This means that if the price of land were to increase, the quantity of land supplied would not increase by a significant amount, as there is a limited amount of land available. Similarly, if the price of land were to decrease, the quantity of land supplied would not decrease by a significant amount, as landowners are unlikely to reduce the amount of land they own in response to a price change.
In contrast, factors like labor, capital, and wages are generally considered to be more elastic, as changes in their price can often result in changes in the quantity supplied or demanded. For example, if the wage rate for a particular type of labor were to increase, workers might be more willing to work longer hours or take on additional jobs, which would increase the quantity of labor supplied.
Overall, the concept of elasticity is an important one in economics, as it helps to explain how changes in price can affect the behavior of consumers and producers in a market.
Question 25 Report
Which of the following is not an indicator of economic growth?
Answer Details
The indicator of economic growth that is not in the list is "High Level of Unemployment."
CPI (Consumer Price Index) and PPI (Producer Price Index) are measures of inflation, which is the rate at which the general level of prices for goods and services is increasing over time. Inflation is an important consideration for economic growth because if it is too high, it can negatively impact economic activity.
GDP (Gross Domestic Product) is a measure of the total value of all goods and services produced within a country's borders in a specific time period. GDP is one of the most commonly used indicators of economic growth because it reflects the overall level of economic activity in a country.
On the other hand, a high level of unemployment is not an indicator of economic growth. In fact, high unemployment is often a sign of a struggling economy. Unemployment means that there are fewer people working and contributing to the production of goods and services, which can lead to a decrease in economic activity. When people are unemployed, they may also have less money to spend, which can further reduce economic growth. Therefore, a high level of unemployment is not a positive indicator of economic growth.

Question 27 Report
Which of the following is not a function of the money market?
Answer Details
The option "creation of long term" is not a function of the money market.
The money market is a financial market where short-term borrowing and lending of funds take place. It is a market for financial instruments with high liquidity and short maturities, generally less than a year. The primary function of the money market is to provide short-term finance to individuals, businesses, and governments.
The three main functions of the money market are:
1. Provision of finance: The money market provides finance to individuals, businesses, and governments through the sale of short-term financial instruments like treasury bills, commercial papers, certificates of deposit, and repurchase agreements.
2. Enhance loan savings: The money market helps to channel savings into productive investments by providing a source of short-term funding for banks and other financial institutions. This, in turn, enables these institutions to offer loans and mortgages to customers.
3. Facilitation of trading and liquidity: The money market provides a platform for the buying and selling of short-term financial instruments. These instruments are highly liquid, which means they can be easily converted to cash when needed. This feature enhances the liquidity of the financial system, which is essential for the smooth functioning of the economy.
In summary, the money market is a vital component of the financial system that provides short-term finance, enhances loan savings, and facilitates trading and liquidity. "Creation of long term" is not a function of the money market since it deals with long-term financing, which is the role of the capital market.

Answer Details
The production within the domestic territory of a country is called the "gross domestic product" or "GDP."
Gross domestic product (GDP) is a measure of the total value of all goods and services produced within the geographical boundaries of a country during a given period, typically a year. This includes all production by businesses, households, and the government.
GDP is an important indicator of a country's economic performance and is often used as a proxy for measuring its standard of living. It reflects the size of a country's economy and provides a broad measure of its economic activity.
In contrast to gross domestic product, "gross national product" (GNP) measures the total value of all goods and services produced by a country's citizens, both domestically and abroad, during a given period. However, since it includes production by citizens abroad, it can be influenced by factors such as international trade and investment, making it less reflective of the economic activity within a country's borders.

Its main goal is the promotion of the economic integration among its
members. Indeed, ECOWAS is one the five regional pillars of the African
Economic Community (AEC). ECOWAS has three official languages: English,
French, and Portuguese. Members producing the same or identical goods

other countries outside its membership
Question 32 Report
Which of the following is NOT an instrument in the money market?
Answer Details
Stocks and shares are NOT instruments in the money market.
The money market refers to the financial market where short-term financial instruments are traded. These instruments are typically very liquid, which means they can be easily bought and sold for cash without significantly impacting their market value. The money market is used by businesses, governments, and other organizations to borrow or lend money for short periods of time.
Treasury bills and bills of exchange are both examples of short-term financial instruments that are traded in the money market. A treasury bill is a type of government bond that matures in less than one year, while a bill of exchange is a written agreement between two parties that allows one party to pay a specific amount of money to the other party at a later date.
Call money funds are mutual funds that invest in short-term debt instruments, such as commercial paper and certificates of deposit. These funds allow investors to pool their money together and invest in a diversified portfolio of short-term securities.
In contrast, stocks and shares are not typically considered short-term financial instruments, as they represent ownership in a company rather than a debt obligation. Stocks are bought and sold on the stock market, which is a separate financial market from the money market. While stocks can be bought and sold quickly, their prices are much more volatile than the prices of short-term financial instruments in the money market.

Goods sold in perfectly competitive markets are generally
Answer Details
Goods sold in perfectly competitive markets are generally homogenous. This means that the products are of the same quality, have the same features and characteristics, and are interchangeable with each other. In a perfectly competitive market, there are many buyers and sellers, and no single buyer or seller has any significant market power to influence the price of the good. As a result, the products are sold at the market price, which is determined by supply and demand, and all buyers and sellers receive the same price for the product. This is why the goods must be homogenous - if they were not, then some sellers could charge a higher price for a higher quality product, and buyers would have an incentive to only buy the higher quality product, which would create market power and reduce competitiveness.

Question 37 Report
Changing the structure of a commodity in order to increase its utility is called?
Answer Details
The correct answer is: Form utility.
Form utility is the process of changing the form, shape, or structure of a commodity or product in order to increase its usefulness or utility to consumers. This can involve converting raw materials into finished goods, assembling various components into a final product, or changing the physical characteristics of a product to better suit consumer needs.
For example, a clothing manufacturer may take raw materials like cotton or silk and transform them into finished garments like shirts, pants, and dresses. By doing so, the manufacturer is adding form utility to the raw materials, which increases their value to consumers.
Another example is the process of packaging food items. By putting food into a can, box, or other type of container, the food becomes more convenient to store, transport, and consume. This additional form utility increases the value of the food to consumers and allows producers to charge a higher price.
Form utility is an important concept in economics because it helps explain how value is created in the production and distribution of goods and services. By adding form utility to a product, producers are able to differentiate their offerings from those of competitors, increase consumer demand, and ultimately earn a profit.
Question 38 Report
The bowed shape of the Production possibilities curve illustrates _________
Answer Details
Production possibility curve (PPC) shows the possible combination of different commodities that can be produced in a given economy given the prevailing level of technology, if all the available productive resources are efficiently utilised.
The reason for the shape of the PPC is something called the law of increasing opportunity costs. Basically, what this means is that as an economy devotes more of its resources to one kind of product, it becomes less efficient because, not all resources are equally suitable for all the industries. If resources are transferred from good A to B, initially the resources to be transferred will be those which could be the least efficient for A. Later, as more of good B needs to be produced, the resources that may be very efficient for good B and not so efficient for good B may also be transferred. In this situation, the economy loses on both sides. That means, the economy is usually inefficient on both ends of the PPC curve while it is the most efficient when resources are appropriately allocated for both goods according to their suitability which make the PPC to be curved. This is why the PPC is flatter at its end point and more curved in the middle.

solving for p: 10 − 5 = 3p + 2p
5 = 5p
p = 1 (given in the equation)
Equilibrium Quantity will be gotten by plugging P into Qd and Qs respectively;
Qd = 10 − 2p Qs = 5 + 2p
= 10 − 2(1) = 5 + 3(1)
= 10 − 2 = 5 + 3
= 8

Which of the following is NOT illustrated by the production possibility curve
Answer Details
The production possibility curve illustrates the concept of opportunity cost and scarcity, but does not necessarily illustrate the concept of risk.
The production possibility curve shows the trade-off between two goods and the maximum amount of one good that can be produced for every possible level of production of the other good. It demonstrates the idea of opportunity cost, which is the cost of one choice in terms of the best alternative choice.
Scarcity is also shown through the production possibility curve, as the curve assumes that resources are limited and that choosing to produce more of one good means producing less of the other.
Allocative efficiency is a point on the production possibility curve where the economy is producing at the most efficient level, meaning that the resources are being used in such a way as to produce the maximum amount of both goods.
Risk, on the other hand, refers to uncertainty about the outcome of an action or decision and is not necessarily illustrated by the production possibility curve.
