Indifference Curves. An indifference curve shows a set of consumption bundles among which the individual is indifferent. Quantity of Y. Combinations (X 1 , Y 1 ) and (X 2 , Y 2 ) provide the same level of utility. Y 1. Y 2. U 1. Quantity of X. X 1. X 2. Marginal Rate of Substitution.

Intermediate Microeconomics. Utility Theory. Utility. A complete set of indifference curves tells us everything we need to know about any individual’s preferences over any set of bundles. However, our goal is to build a model that is useful for describing behavior.

Family Utility Maximization. The goal of the family is to maximize utility by choosing a combination of home work and market work. Household production. You can cook and eat a steak at home or you can go out to eat a steak. The household production takes time to prepare.
