Study Notes
Course Information

- Offered to Year: 2
- Academic Calendar: 2023/2024
- Course Lecturer: Maonga B.B.
Topic 2: Theory of Consumer Behaviour and Utility Maximization
- Consumer Choice and Budget Constraint: Consumer behaviour involves decisions to maximize satisfaction from goods and services. A consumer faces consumption choices and a budget constraint.
- Rational Behaviour: Consumers are rational and try to use their income wisely to maximize satisfaction or utility.
- Preferences: Consumers have clear preferences for specific goods and services, and the utility obtained from successively consuming units varies.
Dimensions of a Typical Consumer's Situation (Continued)
- Budget Constraint: Consumers have a fixed and limited amount of income, even those earning large sums. Scarcity is a reality.
- Prices: Goods have prices due to scarcity, limiting the choices consumers can make. A consumer must compromise and select a satisfactory mix of goods and services.
Approaches to the Study of the Theory of Consumer Behaviour
- There are two approaches to the theory
- Marginal Utility Approach (Cardinal Utility Approach)
- Indifference Curves Approach (Ordinal Utility Approach)
2.1.1 Marginal Utility (Cardinal Utility) Approach
- Marginal Utility: Concerns the additional utility consumers derive from consuming extra units of goods.
- Concept of Utility: Defined as the satisfaction or pleasure gained from consuming goods or services. A product has utility if it satisfies a want.
Characteristics of Utility Concept
- Utility and Usefulness: Utility and usefulness are not synonymous; something can be useful but not provide utility, and something can be useful in a specific area and not in another
- Subjectivity: Utility is subjective, varying greatly from person to person for the same product.
- Quantification: Quantifying utility (using utils) is difficult due to its subjective nature.
Total Utility (TU) and Marginal Utility (MU)
- Total Utility: The total satisfaction derived from consuming a certain quantity of a good or service.
- Marginal Utility: The extra satisfaction from consuming one additional unit of a good or service.
- Relationship between TU and MU: MU decreases as consumption increases; TU increases, reaches a maximum, then decreases. MU can be seen as the change in TU.
The Law of Diminishing Marginal Utility
- Diminishing Marginal Utility: The principle that additional units of a good/service yield progressively less extra satisfaction as consumption increases.
- Utility and Wants: Consumers can fulfill specific wants through more units of a good, but utility (satisfaction) diminishes with each additional unit.
- Durable Goods: The law applies to durable goods like cars; the desire for successive units diminishes.
Consumer Equilibrium and the Law of Equi-Marginal Utility
- Utility Maximization Rule: To maximize satisfaction, consumers allocate their income so that the last unit spent on each good yields the same marginal utility.
- Consumer Equilibrium: A state where consumers have "balanced their margins," and there is no incentive to reallocate spending.
Conditions to Achieving Consumer Equilibrium
- Condition A: The consumer cannot increase his/her total utility by reallocating expenditure.
- Condition B: The constrained condition is the budget line.
Application
- Application Example: Using data, Thoko can find the combination of goods/services that maximizes satisfaction.
Decision Making Process
- Utility Maximizing Combination: This involves combining both total and marginal utility to ascertain the best combination of goods that the consumer can afford with a limited income.
Inferior Options
- Other Combinations: Other combinations of goods may exist that yield less utility than the optimal combination.
Further Application
- Utility Maximizing Combination: Determining optimal choices for multiple products.
Utility Maximization and the Demand Curve
- Inverse Relationship: Product price and quantity demanded are inversely related.
- Determinants of Demand: Preferences, income, and prices of other goods are key factors.
Deriving the Demand Schedule and Curve
- Example: Finding a consumer's demand for a commodity, by determining the different quantity that can be purchased at varying prices with limited income.
Sketching the Demand Curve
- Demand Curve: Depicts a relationship between price and quantity demanded.
Class Work
- Income Change: Determining the optimizing combination of products with a different budget
- Marginal Utility and Demand Curve: Using data and tables, the process for deriving a demand curve from the maximizing rule is shown.
Condition B: The Constrained Condition is the Budget Line
- Budget line: A schedule or curve that depicts various combinations of two products, X and Y that a consumer can purchase given an income restriction. Budget line is determined by prices of both X and Y, as well as the consumer's income.
Example of a Budget Line
- Various combination of goods and services that can be purchased, with varying prices for each good/service, while taking into consideration income.
The Slope of the Budget Line
- Slope Calculation: The slope of the budget line reflects the ratio of the price of the good to be obtained, relative to the given income.
Characteristics of the Budget Line
- Income Changes: Changes in income affect the budget line.
- Prices of Goods Change: Changes in price of goods affect the budget lines.
2.1.2 Indifference Curve (Ordinal Utility Approach): What is Preferred
- Budget Lines vs Indifference Curves: Budget lines represent objective data, while indifference curves reflect subjective consumer preferences.
- Indifference Curve: A curve that represents all possible combinations of two products, A and B, that result in same total satisfaction or total utility.
Indifference Schedule (Table)
- Combination of goods: This demonstrates some combinations of goods/services whose respective utility for the consumer is the same.
Indifference Curve
- Hypothetical Example: Demonstrating a hypothetical example of indifference curve for Products A and B.
Indifference Curve (continued)
- Characteristics: Indifference curves are downward sloping, and are convex to the origin.
- Marginal Rate of Substitution (MRS): The slope of the indifference curve at any point indicates the rate at which the consumer is willing to substitute one product for another at the same level of satisfaction.
Rationale for Convexity of the Indifference Curve
- Rationale of MRS: Consumer's preference and the amounts of product they possess at a particular point affects their willingness to substitute one product for another.
Rationale for Convexity of the Indifference Curve (continued)
- Change Along the Curve: The willingness to substitute one product for another diminishes along the curve.
The Indifference Map
- Series of Indifference Curves: A series of indifference curves. In this scenario, the further away from the origin the curve is, the higher the level of total utility.
Equilibrium at Tangency
- Consumer's Equilibrium: The point on a higher indifference curve, and where the consumer's budget line is tangent, represents the optimal combination of goods/services.
Equilibrium at Tangent
- Equilibrium Position: The point where the budget line is tangent to the indifference curve. This point represents the highest attainable indifference curve.
- Quantities Purchased: Specific quantities of goods A and B are purchased.
- Income: Income for purchasing is specified, and the point in question represents the optimum with the given income.
The Measurement of Utility
- Utility Measurability: Marginal utility theory assumes measurable utility; the consumer can specify the additional utility of additional units of a good.
- Indifference Curve Approach: The indifference approach does not require measuring utility numerically.
Equilibrium in MU and Indifference Curve Theories
- Comparing Equilibrium Positions: When marginal utility and indifference curves theories are compared the resultant is the same, the slope of the indifference curve's equal for the budget line
The Derivation of the Demand Curve(2)
- Exercise: The exercise involved the derivation of the demand curve for a fixed price of one product, with a varying price of another product. The variables in the derivation were prices, income, budget lines and the indifference curves.
