Study Notes
Consumer Choice Theory
- Consumers face limited resources, impacting their purchasing decisions
- Consumers evaluate prices to select goods that best fit their needs
- Consumer behaviour theory explains how consumers make buying choices
- Demand curves summarize consumer decisions, reflecting willingness to pay
- Price increases lead to lower quantity demanded (reduced willingness to purchase)
- Consumer choice theory provides deeper insight into purchasing behaviours
Budget Constraint
- Consumer spending is limited by income
- Budget constraints identify affordable consumption bundles given prices and income
- Budget constraints illustrate trade-offs between products (limited resources)
- Budget constraints are visualized as straight lines in graphs
- The slope reflects the relative price of goods, representing the tradeoff.
Consumer Preferences
- Preferences influence consumer choices among different consumption bundles
- Indifference curves depict consumption bundles that provide equal satisfaction
- Higher indifference curves represent higher levels of utility (satisfaction)
- Indifference curves slope downward, reflecting willingness to substitute one good for another
- Indifference curves do not cross, as this violates the idea of consistent preferences
- Indifference curves can be bowed inward, illustrating how willingness to trade off goods changes as consumption levels change
Optimal Choices
- Consumers aim for the maximum utility (satisfaction) within their budget constraints
- Optimal choice occurs where the highest indifference curve touches the budget constraint
- The tangency point signifies equal marginal rates of substitution and relative prices
- Changes in price or income shift budget constraints, influencing consumer choices
Income and Substitution Effects of Price Changes
- Income effect: Increased purchasing power due to lower prices, leading to increased consumption of both goods.
- Substitution effect: One good becomes relatively cheaper, leading to increased consumption of that good and reduction of the other.
- These effects interact; the final change in consumption depends on specific preferences and the relative strengths of both effects.
Factors Affecting Consumer Choices
- Changes in income shift the budget constraint, influencing optimal choices
- Price changes alter the slope of the budget constraint, causing substitution and income effects.
Applications of Consumer Choice Theory
- Demand curves can slope upwards (Giffen goods)-income effect outweighs substitution effect
- Wages affect labor supply decisions—influencing consumer decisions about leisure and work (income and substitution)
- Interest rates affect saving (income and substitution)
- Cash vs. in-kind transfers: choices depend on preferences between goods.
