Study Notes
Consumer Behavior Theory
- Consumer behavior theory examines how scarcity affects individual consumer choices when deciding on goods and services for satisfaction.
- Consumers purchase goods and services to gain satisfaction from their possession.
Consumer Preferences, Utility, and Choice
- Consumers have diverse preferences for the vast array of goods and services available.
- Economic theory of consumer behavior uses concepts like budget constraints, consumer preferences, and consumer choice.
Budget Constraint
- A budget constraint limits the quantity of goods a consumer can purchase due to their fixed income.
- An example equation is Px * X + Py * Y < M
- Px: Price of good X
- Py: Price of good Y
- X: Quantity of good X
- Y: Quantity of good Y
- M: Money income of the consumer
- A budget line illustrates combinations of goods (X and Y) where total expenditure equals income: Px * X + Py * Y = M
Preference Ordering
- Consumer preferences are used to rank goods in order of desirability.
- Assumptions of consumer preference ordering include completeness (ability to compare and rank goods), consistency (consistent ranking over time), and no satiation (always preferring more of a good).
Utility
- Utility refers to the level of satisfaction derived from consuming a good or engaging in an activity.
- Utility is subjective and varies between individuals and over time.
- Examples include drugs and alcohol, despite social implications, giving satisfaction.
Consumer Behavior Approaches
- Economists analyze consumer behavior through cardinal and ordinal utility approaches.
- Cardinal utility assumes utility is measurable (quantifiable using total and marginal utility).
- Ordinal utility assumes utility is rankable using indifference curves (curves representing combinations of goods providing equal satisfaction).
Cardinal Utility Analysis
- Utility is measured in terms of units (utils).
- Total utility is the total satisfaction from consuming a specific number of units.
- Marginal utility is the additional satisfaction from consuming one more unit
Principle of Diminishing Marginal Utility
- The principle states that as consumption of a good increases over a period, the marginal utility decreases.
- Graphically represented by total utility increasing at a decreasing rate up to a maximum point and then declining.
Consumer Equilibrium-Cardinal Utility
- Consumer Equilibrium occurs when a consumer maximizes their utility within their given price and income constraints.
- The condition for equilibrium in the case of a single good X is when Marginal Utility of X (MUx) is equal to its market price (Px).
Ordinal Utility Approach
- Utility is not considered measurable; instead, preferences are ranked using indifference curves.
- Indifference curves show all combinations of goods that provide equal satisfaction, sloping downwards and being convex to the origin, representing diminishing marginal rates of substitution.
- The consumer is in equilibrium when the highest attainable indifference curve is tangent to their budget line.
Derivation of Demand Curve
- The demand curve is derived based on the principle of diminishing marginal utility.
- Graphically, a demand curve is identical to the positive segment of the marginal utility curve.
Budget Line Analysis
- A budget line shows all combinations of goods that a consumer can afford given their income and prices of the goods.
- Changes in price or income shift the budget line.
Income and Price Effects on Consumption
- Changes in income and price impact how consumers spend their income.
- Normal goods show increases in demand with increased income.
- Inferior goods show decreased demand with increased income.
Elasticity
- Elasticity measures the responsiveness of one variable to changes in another, in percentage terms.
- Price elasticity of demand measures how quantity demanded changes with price variation.
- Income elasticity of demand measures how quantity demanded changes with income variation.
- Cross-price elasticity of demand measures how quantity demanded of one good changes with the price of another.
