    Study Notes

    Consumer Choice Theory

    • Consumer choice theory examines how individuals make decisions about what to purchase given their budget constraints and preferences.
    • The theory considers how factors like income and price changes affect purchasing decisions.

    Budget Constraint

    • The budget constraint illustrates the limit on consumption bundles a consumer can afford.
    • It's determined by income and prices of goods.

    Consumer's Budget Constraint

    • The budget constraint line represents various combinations of goods a consumer can afford.
    • Any point on this line indicates the trade-off available between two goods.

    The Consumer's Budget Constraint Line

    • Represents all combinations of goods affordable with the consumer's income and prices.
    • The slope of the line indicates the relative price of one good compared to another.
    • Changing income shifts the line outwards, while changing prices rotate the line and affect the slope.

    Indifference Curves

    • Indifference curves show various combinations of goods a consumer views as having the same level of satisfaction.
    • Higher indifference curves represent greater levels of utility.

    Properties of Indifference Curves

    • Higher indifference curves are preferred to lower ones because they represent higher levels of satisfaction.
    • Indifference curves are downward sloping, reflecting the trade-offs between goods.
    • Indifference curves do not intersect, because each curve represents a unique level of satisfaction.
    • Indifference curves are bowed inward, reflecting the diminishing marginal rate of substitution.

    Marginal Rate of Substitution (MRS)

    • The MRS is the rate at which a consumer is willing to trade one good for another while maintaining the same level of satisfaction.
    • It's represented by the absolute value of the slope of the indifference curve at any point.

    Consumer's Optimum

    • The consumer's optimum occurs at the point where the highest achievable indifference curve is tangent to the budget constraint.
    • This point represents the consumption bundle that maximizes the consumer's level of satisfaction, given the budget constraint.

    Income and Substitution Effects

    • A price change for a good has both an income and substitution effect.
    • Substitution Effect: A change in consumption due to the price change itself, moving along an indifference curve.
    • Income Effect: A change in consumption due to the change in purchasing power, moving to a higher or lower indifference curve.

    Normal Goods

    • If a consumer buys more of a good as his or her income increases, the good is a normal good.

    Inferior Goods

    • If a consumer buys less of a good as his or her income increases, the good is an inferior good.

    Giffen Goods

    • A special case of an inferior good where the income effect outweighs the substitution effect, leading to an upward-sloping demand curve.
    • This happens when the good is a significant part of the consumer's budget.

    Labor Supply

    • The worker's supply of labour is influenced by income and substitution effects, resulting in a potentially backward-sloping labour supply curve.

    Household Saving

    • Higher interest rates potentially increase saving based on substitution and income effects.

    Summary

    • Budget constraints depict the consumer's attainable bundles of goods.
    • Indifference curves represent consumer preferences – higher curves are preferred.
    • The optimal consumption bundle lies where the highest indifference curve is tangent to the budget line.
    • Price changes have both income and substitution effects.
    • Applying these principles helps economists understand consumer decisions and market behavior in various contexts, including labour supply and household saving.
