    Study Notes

    Consumer Behaviour

    • Economists study how individuals decide how to spend their income on goods.
    • Consumers naturally seek the combination of goods that maximizes satisfaction, given their budget.
    • Consumer preferences ("likes") and affordability (prices and income) influence choices.
    • This chapter outlines two consumer behaviour models: Cardinal Utility Analysis and Ordinal Utility Analysis.

    Preliminary Notations and Assumptions

    • Consumers typically consume multiple goods; for simplicity, this study focuses on two goods (bananas and mangoes).
    • A "consumption bundle" represents the quantities of these goods.
    • Variables (x₁, x₂) represent banana and mango quantities, respectively. They can be zero or positive.
    • Examples of bundles: (5, 10) has 5 bananas and 10 mangoes; (10, 5) has 10 bananas and 5 mangoes.

    Utility

    • Utility is the want-satisfying capacity of a commodity.
    • Higher need or desire for a good translates to greater utility.
    • Utility is subjective; different individuals perceive different levels of utility from the same commodity.
    • Utility can be influenced by factors like time and location.

    Cardinal Utility Analysis

    • This approach assumes utility can be quantified numerically.
    • Total Utility (TU): Total satisfaction derived from consuming a certain amount of a commodity. Increasing consumption usually increases TU.
    • Marginal Utility (MU): The change in total utility resulting from consuming one additional unit of a commodity. MU typically diminishes as consumption increases.
    • MU = TUn - TUn-1 (where n is the nth unit)

    Ordinal Utility Analysis

    • This approach ranks consumption bundles by preference without assigning numerical values to utility.
    • Indifference Curves: Curves connecting bundles providing equal utility to the consumer.
    • Indifference Map: A set of indifference curves showing different levels of utility; higher curves indicate higher levels of total satisfaction.
    • Marginal Rate of Substitution (MRS): Rate at which a consumer is willing to trade one good for another while maintaining the same level of total utility. MRS typically diminishes for most goods, as substitution becomes less desirable with increased consumption of a good.

    Demand Curve

    • Demand Curve: A graphical representation of the relationship between the price of a good and the quantity demanded, assuming other factors are constant (prices of other goods, income, preferences etc.).
    • The demand curve is typically downward sloping due to the law of diminishing marginal utility. The law of diminishing marginal utility states that the marginal utility of a commodity diminishes with the increase in consumption.
    • Budget Line: A line that represents all the consumption bundles that a consumer can afford given their income and prices of the goods.
    • The point where the budget line is tangent to the highest possible indifference curve represents the optimal consumption bundle for the consumer.
