Scarcity, Preferences, and Feasibility

Scarcity and Utility Maximization

• Scarcity and Resources: Scarcity can manifest in two ways: either an option is simply not available, or there is a limitation of resources, such as budget or time.

• Preferences and Budget: Individual choices are guided by preferences (how one ranks goods, e.g., hot dog vs. burger) and constrained by a budget.

• Goal of Individuals: The primary goal is to maximize happiness or utility.

• Constraints on Maximization: Utility cannot be maximized indefinitely due to scarcity.

• Assumptions (Example Scenario):

  • No Past/Future: In a specific example, it was assumed that there is no past (no savings to draw from) and no future (no ability to save), meaning all decisions relate to immediate consumption and leisure.

  • Trade-off: Individuals face a trade-off between leisure and consumption. Working more allows for more consumption but reduces leisure time.

Preferences and Indifference Curves

• Indifference Preferences: Economists often represent preferences using indifference maps, which consist of indifference curves.

• Definition of Indifference Curve: Each point on a single indifference curve represents a different bundle (combination of goods) that yields the same level of utility or happiness for an individual. The person is
