    Study Notes

    Scarcity and Economics

    • Scarcity is the limited nature of resources.
    • Economics is the study of how societies manage scarce resources.
    • Key decisions include what to buy, how much to work, how much to save and spend, how much to produce, and how many workers to hire.

    People Face Tradeoffs

    • All decisions involve tradeoffs.
    • Examples: choosing to attend a party versus studying, earning more money by working longer hours.
    • Society faces a tradeoff between efficiency and equality.
    • Efficiency is maximizing the use of resources.
    • Equality is distributing prosperity equally.

    Opportunity Cost

    • The opportunity cost of an item is what you give up to obtain it.
    • It is the relevant cost for decision-making.
    • Example: The opportunity cost of attending college is the income and experiences forgone during that time.

    Rational People Think at the Margin

    • Rational people make decisions by considering the costs and benefits of incremental adjustments.
    • They systematically seek to maximize their objectives. 
    • Marginal changes are incremental adjustments to existing plans.

    People Respond to Incentives

    • Incentives motivate individuals to act.
    • Incentives can be rewards or punishments.
