Study Notes

Preferences and Utility

Indifference curves slope downward to the right, indicating that combinations on the curve yield equal satisfaction.
The Marginal Rate of Substitution (MRS) measures the rate at which a consumer is willing to sacrifice one good for another.
The Principle of Diminishing Marginal Rate of Substitution states that as one moves down a convex indifference curve, the curve's slope continuously declines from steep to flat.

Indifference Schedules

Schedule 1 features combinations of goods X and Y, showing varying units from (1, 12) to (5, 2).
Schedule 2 provides a higher quantity satisfaction than Schedule 1, starting from (2, 14) to (6, 4), showing that greater quantities yield more satisfaction.

Indifference Maps

Each point on an indifference map corresponds to a different indifference curve, depicting levels of utility.
Indifference curves have multiple levels of utility represented as U1, U2, and U3, where U3 > U2 > U1.

Marginal Rate of Substitution Changes

MRS varies as quantities of goods X and Y change, reflecting the consumer's willingness to trade between the two.
At points with steeper indifference curves, like (x1, y1), consumers give up more of good Y to gain additional units of good X.
At flatter indifference curves, like (x2, y2), consumers are willing to give up less of good Y for more of good X.
The formula for MRS is defined as MRS = -dy/dx = -MUx/MUy, indicating the ratio of marginal utilities.

Properties of Indifference Curves

Indifference curves are convex to the origin, emphasizing that consumers are more willing to trade abundance goods and less willing for scarce goods.
Higher indifference curves are preferred as they represent larger quantities of goods.
Indifference curves slope downward as a consumer will trade one good for another to maintain equal satisfaction.
Indifference curves do not intersect, meaning each curve represents a unique utility level.

Consumer Preferences

Average combinations of goods are generally preferred over extreme combinations, illustrating consumer behavior towards balanced consumption.
Higher indifference curves indicate a preference for more of a good, aligning with the idea that consumers desire more rather than less.
