Study Notes

Chapter 5: The Theory of Consumer Behaviour

Consumer behavior is the study of consumers during the process of consumption.
Utility refers to the satisfaction obtained from consuming goods or services.

The Concept of Utility

Cardinal Utility Theory focuses on the measurable nature of utility.
Total Utility measures the overall satisfaction from consumption.
Marginal Utility is the extra satisfaction from one more unit of consumption.
The Law of Diminishing Marginal Utility states that marginal utility decreases as more units of a good are consumed.
Consumer Equilibrium using the Mathematical Method, involves equating marginal utilities per price for each good.

Ordinal Utility Theory

Ordinal Utility Theory states that utility is comparable but not measurable.
The Budget Line (Constraint) illustrates the options a consumer can afford, based on income and prices of goods.
The slope of the budget line depicts the relative price of one good concerning the other.
Changes to the budget line result from adjustments to either income or prices of goods.
Indifference Curves illustrate combinations of goods that provide the same level of satisfaction to the consumer.
The slope of an indifference curve is the Marginal Rate of Substitution (MRS).
The Marginal Rate of Substitution (MRS) shows the rate at which one good is substituted for another, along an indifference curve.
Indifference maps represent different levels of satisfaction with varying combinations of goods.
Higher indifference curves indicate higher levels of satisfaction.

Changes in Budget Constraint

Changes in prices of goods affect the budget line's slope.
Adjustments in income affect the position of the budget line. The budget line shifts parallel to the original line, when income changes.
When a good's price changes, it affects the slope of the budget line and will change the quantity demanded.
