Study Notes
Consumer Sovereignty and Indifference Curves
- Indifference Curve: Represents combinations of goods providing the same level of satisfaction.
- Marginal Rate of Substitution (MRS): Indicates how many units of one good must be traded for one additional unit of another while maintaining satisfaction.
-
Assumptions:
- Consumers are rational.
- Utility is measured ordinally (ranking preferences, not assigning numerical values).
- Diminishing Marginal Rate of Substitution: As a consumer consumes more of a good, their willingness to trade another good for that good decreases.
- Total utility depends on the quantity of goods consumed.
- Only two goods are considered for simplicity.
-
Characteristics of Indifference Curves:
- Negative Slope: As you increase consumption of one good, you must decrease consumption of the other to maintain satisfaction.
- Convex to the Origin: The slope of the indifference curve gets flatter as you move along it, reflecting diminishing MRS.
- Do Not Intersect: Each indifference curve represents a unique level of satisfaction, so they cannot cross.
- An Infinite Number of Indifference Curves: Consumers can have an infinite range of satisfaction levels.
-
Budget Line: Shows the combinations of goods a consumer can afford given a specific income and prices.
- Price Decrease: Shifts the budget line outward (to the right).
- Price Increase: Shifts the budget line inward (to the left).
- Income Change: Shifts the entire budget line outward for increased income, inward for decreased income.
Consumer Equilibrium and Demand Curve
-
Consumer Equilibrium: Occurs when the consumer maximizes satisfaction given their budget constraints.
- Condition: The budget line touches the highest possible indifference curve.
- Marginal Rate of Substitution (MRS) = Price Ratio: The slope of the indifference curve matches the slope of the budget line at the equilibrium point, implying that the value the consumer places on each good (MRS) equals their relative prices.
- Demand Curve: A graph showing the relationship between the price of a good and the quantity demanded, with the consumer maximizing their satisfaction at each point.
Income and Price Effects
- Engel Curve: Illustrates the relationship between income and the quantity demanded of a good.
- Income-Consumption Curve: A curve connecting different consumer equilibrium points resulting from income changes, keeping prices constant.
- Price-Consumption Curve: A curve connecting different consumer equilibrium points resulting from changes in the price of one good, keeping the price of the other good and income constant.
Consumer Behavior and Utility Theory
- Utility: The satisfaction a consumer derives from consuming goods and services.
- Law of Diminishing Marginal Utility: The utility derived from consuming additional units of the same good decreases as consumption increases.
- Marginal Utility (MU): The additional utility gained from consuming one more unit of a good.
- Total Utility (TU): The total satisfaction obtained from consuming all units of a good.
- Point of Satiation: The point where consuming more of a good provides no additional utility (MU = 0).
-
Relationship between MU and TU:
- When consuming the first unit of a good, MU = TU.
- As consumption increases, MU is positive and decreasing, while TU increases at a decreasing rate.
- At the point of satiation, MU = 0, and TU reaches its maximum.
- Beyond the point of satiation, MU becomes negative, and TU decreases.
-
Consumer Equilibrium:
- Single Good: The marginal utility derived from the good equals the marginal utility sacrificed to obtain it.
-
Multiple Goods: The marginal utility per unit of money spent on each good is equal, which in turn equals the marginal utility of a unit of currency. This means both conditions are met:
- Marginal utility of a unit of currency is equal across all goods.
- Available income equals total expenditure on goods.
