Question 1 Report
(a) Explain the following types of taxes:
i. specific tax
ii. value-added tax
(bi) With the aid of diagrams, describe the effects of an indirect tax on a commodity when demand is:
perfectly inelastic
(ii) With the aid of diagrams, describe the effects of an indirect tax on a commodity when demand is:
perfectly elastic
(a) Types of Taxes:
(bi) Effects of Indirect Tax on Commodity when Demand is Perfectly Inelastic:
When demand is perfectly inelastic, a change in price does not affect the quantity demanded. Therefore, the imposition of an indirect tax on the commodity will not affect the quantity demanded. The entire burden of the tax will be borne by the consumer, and the price paid by the consumer will increase by the full amount of the tax. The diagram below illustrates the effects of an indirect tax on a commodity with perfectly inelastic demand.
the demand curve is perfectly vertical, and the supply curve shifts upward to represent the tax. The vertical distance between the old and new supply curves represents the tax, and the entire burden is paid by the consumer as the price paid increases by the full amount of the tax.
(ii) Effects of Indirect Tax on Commodity when Demand is Perfectly Elastic:
When demand is perfectly elastic, a small increase in price will cause the quantity demanded to fall to zero. Therefore, the imposition of an indirect tax on the commodity will result in the entire burden of the tax being borne by the supplier. The price paid by the consumer will remain the same, and the supplier will have to bear the full amount of the tax. The diagram below illustrates the effects of an indirect tax on a commodity with perfectly elastic demand.
the demand curve is perfectly horizontal, and the supply curve shifts upward to represent the tax. The vertical distance between the old and new supply curves represents the tax, and the entire burden is paid by the supplier as the price received remains the same.

(d) The diagram below shows the effects of the introduction of a subsidy on the production of maize. Study the diagram and answer the questions that follow.
If the quantity demanded of maize increases from 20 to 40 bags as a result of a fall in price from $15 to $10, calculate the price elasticity of demand.
(e) The diagram below shows the effects of the introduction of a subsidy on the production of maize. Study the diagram and answer the questions that follow.
State the type of elasticity of demand in 2(d).
(ai) - The curve X represents the demand curve
- The curve Y represents the old supply curve
- The curve Z represents the new supply curve
(aii) Subsidy will shift the supply curve to the right causing price to fall and the quantity demanded to increase
(bi) Total revenue = Price x Quantity
Before subsidy, TR = 20 x 15
= $300
(bii) After subsidy, TR = 10 x 40
= $400
(c) % increase in revenue = 400 - 300/300 x 100
= 33.33%
(d) e = ∆Qd/∆P x P/Qd
e = 40 - 20/10 - 15 x 15/20
e = 20/-5 x 15/20
e = - 3 since elasticity is always positive. Therefore, e = 3
(e) It is an elastic demand because an increase in quantity demanded leads to a fall in the price of maize.

From the data, answer the following questions.
Calculate the: Gross National Product (GNP)
(c) A hypothetical national income data for a country in particular year is presented below:
| ITEM | $MILLION |
| Wages and salaries | 250 |
| Income paid abroad | 75 |
| Income from self employment | 120 |
| Stock appreciation | 5 |
| Interest | 10 |
| Income received from abroad | 50 |
| Rent | 25 |
| Depreciation allowance | 3 |
| Royalties | 2 |
| Profits and dividends | 35 |
From the data, answer the following questions.
Calculate the: Net National Product (NNP)
(a) To calculate the Gross Domestic Product (GDP), we need to sum up all the domestic income earned within the country. This includes wages and salaries, income from self-employment, rent, depreciation allowance, and profits and dividends. GDP = 250 + 120 + 25 + 3 + 35 = $433 million. (b) To calculate the Gross National Product (GNP), we need to add the income received from abroad and subtract the income paid abroad from GDP. This includes income received from abroad, which is $50 million, and income paid abroad, which is $75 million. GNP = GDP + Income Received from Abroad - Income Paid Abroad = $433 + $50 - $75 = $408 million. (c) To calculate the Net National Product (NNP), we need to subtract depreciation allowance from GNP. This is because depreciation is the decrease in the value of assets used in production and it needs to be accounted for to accurately measure the country's economic output. NNP = GNP - Depreciation Allowance = $408 - $3 = $405 million. In summary, the GDP is the total income earned within the country, the GNP is the total income earned by the country's residents (including income from abroad), and the NNP is the GNP minus the depreciation allowance.

Question 4 Report
(a) Distinguish between labour force and efficiency of labour
(b) Describe five factors which determine the size of the labour force in a country
(a) Labour force and efficiency of labour are two related but distinct concepts. The labour force refers to the total number of people who are employed or actively seeking employment in a particular country or region. This includes both employed and unemployed individuals who are able and willing to work. Efficiency of labour, on the other hand, refers to the productivity or output of a given unit of labour in a given period of time. It is a measure of how much output can be produced with a given amount of labour input.
(b) There are several factors that can determine the size of the labour force in a country. These include:
Therefore, the five factors that determine the size of the labour force in a country are population growth, age distribution, education and training, immigration and emigration, and labour force participation rate.

Question 5 Report
(a) What is a demand schedule?
(b) Explain each of the following terms:
→ effective demand
→ composite demand
→ derived demand
(ci) Using appropriate diagrams, explain how a change in the price of a commodity would influence the demand of its:
substitute
(ii) Using appropriate diagrams, explain how a change in the price of a commodity would influence the demand of its:
complement
(a) A demand schedule is a table or chart that shows the quantity of a good or service that consumers are willing and able to purchase at different price levels, while other factors remain constant. It represents the relationship between price and quantity demanded, demonstrating the amount of a product consumers are willing to buy at various price points.
(b) Here are explanations for each of the terms mentioned:
(ci) A change in the price of a commodity can influence the demand for its substitute. Let's consider the scenario of coffee and tea as substitutes. If the price of coffee increases, it becomes relatively more expensive compared to tea. As a result, consumers may switch their preference from coffee to tea due to the lower price. This change in price creates an incentive for consumers to substitute one product (coffee) with its alternative (tea), leading to an increase in the demand for tea.
To illustrate this on a demand diagram, we would see a shift in the demand curve for tea to the right. The new equilibrium quantity of tea would increase, indicating higher demand, while the equilibrium quantity of coffee would decrease.
(ii) A change in the price of a commodity can influence the demand for its complement. Let's take the example of cars and gasoline as complements. If the price of cars decreases, it becomes more affordable for consumers, leading to an increase in car purchases. As a result, the demand for gasoline, which is necessary to fuel and operate the cars, would also increase.
On a demand diagram, we would observe a rightward shift in the demand curve for gasoline, indicating an increase in demand. The equilibrium quantity of gasoline would rise as consumers require more fuel to meet the increased demand for cars.
In both cases, the change in the price of a commodity influences the demand for its substitute or complement due to the relationship and interdependence between the products.
