Study Notes

Indifference Curves

An indifference curve represents various combinations of two goods that provide equal satisfaction to a consumer.
These curves illustrate a consumer’s preferences, depicting bundles that yield the same level of utility.
Utility is an abstract measure used to express consumer satisfaction.
The slope of the indifference curve indicates the marginal rate of substitution between two goods, depicting how much of one good a consumer is willing to forgo for another.

Characteristics of Indifference Curves

Indifference curves are typically drawn convex to the origin, demonstrating diminishing marginal utility.
Curves cannot intersect; higher curves denote higher levels of utility (if U1 < U2 < U3).
As one moves to higher curves, the consumer experiences increased satisfaction.

Budget Constraints

A budget constraint represents the combinations of goods that a consumer can afford based on their income and the prices of the goods.
The formula for a budget constraint is P(x)·Q(x) + P(y)·Q(y) ≤ M, where P is the price and Q is the quantity.
The constraint shifts outward as income increases, allowing for a greater range of affordable combinations.

Utility Maximization

Consumers aim to maximize utility within their budget constraints by finding the optimal consumption point where the budget line is tangent to the highest indifference curve.
At this optimal point, the rate at which a consumer is willing to substitute goods is equal to the rate dictated by market prices.

Perfect Substitutes

For perfect substitutes, the indifference curves are straight lines, indicating that consumers can replace one good for another without any loss of utility.
Consumers will choose to buy either one good or the other depending on their relative prices.

Perfect Complements

When goods are perfect complements, indifference curves take an L-shape (like a Leontief utility function).
Such curves indicate that the goods are consumed together in fixed proportions; one cannot increase utility by consuming one good without an equivalent increase in the other.
