Study Notes
Introduction to Consumer Demand Theory
- Utility maximization is the primary goal of consumer behavior.
- Utility is a psychological concept reflecting satisfaction derived from consuming goods.
- Cardinal Utility Approach: Utility is measurable using cardinal numbers (1, 2, 3...).
- Ordinal Utility Approach: Utility is measured based on preferences, not numerically.
Cardinal Utility Approach
- Total Utility (TU) maximization happens when Marginal Utility (MU) equals zero.
- Consumers allocate limited income across goods to achieve equilibrium.
- Assumptions include:
- Rationality: Consumers aim to maximize satisfaction.
- Limited income influences choices.
- Diminishing Marginal Utility: Added satisfaction decreases with increased consumption.
- Constant utility of money and additive utility.
Consumer Equilibrium in Cardinal Utility
- In a single commodity case, consumers prioritize goods based on utility.
- Transitivity of choice ensures consistency in preferences.
- Rational consumers will exhaust their budget until MU from spending equals the price of goods.
Ordinal Utility Approach
- Indifference curves illustrate combinations of two goods yielding the same satisfaction level.
- Diminishing Marginal Rate of Substitution (MRS) indicates less willingness to substitute as more of a good is consumed.
- An indifference curve slope is negative, convex to the origin, and does not intersect.
Properties of Indifference Curves
- Higher indifference curves represent higher satisfaction levels.
- Changes in prices shift budget lines; a decrease in the price of good X shifts the line rightward.
Consumer Equilibrium in Ordinal Utility
- Conditions for equilibrium include:
- First-order condition: MRS must equal the price ratio (MRSx,y = Px/Py).
- Second-order condition: The equilibrium must occur at the highest attainable indifference curve.
- Graphically, equilibrium occurs where the budget line is tangent to the highest indifference curve.
Impact of Income and Price Changes
- Changes in income affect consumer behavior and budget constraints.
- Price fluctuations influence the consumer's ability to purchase goods and adjust consumption accordingly.
- Effects of income and substitution on consumer choice are essential for understanding demand shifts.
