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.
