Study Notes

Utility

Definition: Utility is the satisfaction a consumer receives from consuming a good or service.
Measurable: Although subjective, economists assume utility is measurable in units called "utils".
Marginal Utility: The additional satisfaction received from consuming one more unit of a good or service.
Total Utility: The sum of all marginal utilities received from consuming successive units of a good or service.
Law of diminishing marginal utility: As you consume more of a good, the additional satisfaction you receive from each additional unit decreases.

Indifference Curve

Definition: Represents combinations of two goods that provide the same level of utility for a consumer.
Characteristics:
- Negatively Sloped: Downward slope shows the consumer is willing to trade some of one good for more of another while maintaining the same level of satisfaction.
- Convex to the Origin: Reflects the law of diminishing marginal utility. Consumers are willing to give up more of one good when they already have a lot of it, and less when they have only a little.
- Non-Intersecting: Rational consumers maintain consistent preferences.
Marginal Rate of Substitution (MRS): Shows the rate at which a consumer is willing to trade one good for another.
Budget Line: Represents all possible combinations of two goods that a consumer can purchase given their budget and the prices of the goods.

Consumer Equilibrium

Definition: The point where a consumer maximizes their utility given their budget constraint.
Condition: The consumer will choose the combination of goods where the MRS equals the ratio of the prices of the two goods.
Paradox of Value: Explains why seemingly essential goods (e.g., water) can have lower prices than non-essential goods (e.g., diamonds). This is explained by the combination of supply, demand, and the law of diminishing marginal utility.
