Economics is a fascinating subject that explores how individuals, businesses, and governments make choices about how to allocate resources in a world of limited supply and unlimited wants. For students preparing for their SS 2 Economics exams, understanding key topics is essential. This article provides a comprehensive, easy-to-understand guide to some of the major concepts in economics, including the theory of demand and supply, taxation, public finance, and agriculture policies in Nigeria.
1. Theory of Demand and Theory of Supply
Theory of Demand
The theory of demand explains how consumers make decisions about what goods and services to purchase. The demand for a product is directly related to its price. According to the law of demand, as the price of a good or service decreases, the demand for it increases, and vice versa.
Theory of Supply
The theory of supply explains the quantity of goods and services producers are willing to offer at different prices. The law of supply states that, all other factors being equal, as the price of a good or service increases, the quantity supplied increases, and when the price decreases, the quantity supplied decreases.
Definitions:
- Demand: The quantity of a good or service that consumers are willing and able to purchase at a given price over a specific period.
- Supply: The quantity of a good or service that producers are willing and able to offer for sale at a given price over a specific period.
Law of Supply
The law of supply shows the relationship between the price of a good and the quantity supplied. As the price of a good rises, the quantity of that good supplied also rises, as producers are willing to sell more at higher prices.
Types of Supply
- Composite Supply: When a product is used for more than one purpose, the supply of that product is referred to as composite supply.
- Complementary Supply: This refers to the supply of goods that are used together, such as printers and ink cartridges.
- Competitive Supply: This occurs when two goods compete for the same resources in production.
Tables and Graphs for Law of Supply
Price | Quantity Supplied |
---|---|
1 | 10 |
2 | 20 |
3 | 30 |
4 | 40 |
Graph: A graph showing price on the y-axis and quantity on the x-axis would show an upward-sloping curve, illustrating that as price increases, the quantity supplied increases.
Likely Questions on Theory of Demand and Supply:
- Define demand and explain its relationship with price.
- What is the law of demand?
- Explain the law of supply with an example.
- Differentiate between complementary and competitive supply.
- What is composite supply?
- How does a supply curve typically behave?
- Discuss factors that affect supply.
- How do producers react to changes in market prices?
- Illustrate the law of supply with a graph.
- Explain the significance of the demand-supply relationship in price determination.
2. Abnormal Supply Curve
An abnormal supply curve is one that does not follow the usual upward slope. Instead, it may be downward sloping or have irregular shapes. This could happen due to factors like government intervention, changes in production technology, or market distortions.
Likely Questions on Abnormal Supply Curve:
- What is an abnormal supply curve?
- What factors might cause an abnormal supply curve?
- How does an abnormal supply curve affect market equilibrium?
- Provide examples of markets where abnormal supply curves might occur.
- Explain the differences between normal and abnormal supply curves.
3. Price Determination in a Free Market
In a free market, prices are determined by the interaction of supply and demand. When demand exceeds supply, prices rise, and when supply exceeds demand, prices fall. The equilibrium price is where the quantity demanded equals the quantity supplied.
Likely Questions on Price Determination:
- How is the price of a good determined in a free market?
- What happens when supply exceeds demand in a free market?
- How does a free market achieve equilibrium price?
- What is the role of consumers in price determination?
- Explain how changes in demand and supply affect the market price.
4. Price System
The price system is the mechanism through which prices in a free market are determined by supply and demand forces. Prices act as signals to both consumers and producers. High prices signal scarcity, while low prices signal abundance.
Likely Questions on Price System:
- What is the price system in economics?
- How does the price system guide consumer and producer behavior?
- What role do prices play in a market economy?
- Explain the concept of price signals.
- How does the price system help allocate resources efficiently?
5. Public Finance
Public finance refers to the management of a government’s revenue, expenditure, and debt. It includes the collection of taxes, the allocation of resources to public goods and services, and the management of government borrowing.
Likely Questions on Public Finance:
- What is public finance?
- How does the government generate revenue in public finance?
- What are the key objectives of public finance?
- Discuss the role of taxes in public finance.
- Explain how public finance helps in the distribution of wealth.
6. Taxation
Taxation is the process by which governments collect revenue from individuals and businesses to fund public services and government operations. Taxes can be direct or indirect and include income taxes, sales taxes, and property taxes.
Likely Questions on Taxation:
- What is taxation?
- Explain the difference between direct and indirect taxes.
- How do taxes contribute to government revenue?
- What are the different types of taxes?
- Discuss the impact of taxation on business operations.
7. Uses of Taxation
Taxes serve several purposes, including funding public services like healthcare, education, and infrastructure. They also help in redistributing wealth, controlling inflation, and managing the economy.
Likely Questions on Uses of Taxation:
- What are the main uses of taxation?
- How do taxes contribute to the economy?
- Discuss the role of taxation in wealth redistribution.
- Explain how taxes help control inflation.
- How do taxes finance public goods and services?
8. Budget and Revenue Allocation in Nigeria
A budget is a financial plan that outlines the government’s expected revenue and expenditure over a specific period. In Nigeria, the budget is crucial for ensuring efficient use of public funds. Revenue allocation in Nigeria involves the distribution of funds from federal, state, and local governments.
Likely Questions on Budget and Revenue Allocation:
- What is a national budget?
- How is revenue allocated in Nigeria?
- Discuss the importance of budgeting in the Nigerian economy.
- What challenges does Nigeria face in revenue allocation?
- Explain the role of federal, state, and local governments in revenue allocation.
9. Agriculture Policies in Nigeria
Agriculture policies in Nigeria aim to improve food production, reduce poverty, and enhance the country’s economic development. These policies include initiatives to increase crop yields, improve livestock farming, and modernize agricultural techniques.
Likely Questions on Agriculture Policies:
- What are the main agriculture policies in Nigeria?
- How do these policies support economic growth?
- What challenges face Nigerian agriculture?
- How do government policies affect agricultural production?

10. Marketing of Agricultural Commodities and Prospects of Agriculture
The marketing of agricultural commodities involves the process of selling goods from farmers to consumers. Challenges in this area include inadequate infrastructure, low market access, and fluctuating prices. However, there are significant opportunities for growth, especially with improved policies and technology.
Likely Questions on Marketing and Prospects of Agriculture:
- What are the challenges in marketing agricultural commodities in Nigeria?
- How does marketing affect agricultural prices?
