  • Production Possibilities Frontier (PPF)

    The boundary between combinations of goods and services that can be produced and those that cannot, holding everything else constant.

  • Points on the PPF

    Attainable and efficient in production; represent maximum output combinations.

  • Points outside the PPF

    Unattainable with current resources, illustrating scarcity.

  • Points inside the PPF

    Attainable but inefficient; resources are underutilized.

  • Opportunity Cost

    The amount of one good that must be sacrificed to produce more of another good; calculated as \(\frac{\Delta Y}{\Delta X}\).

  • Shape of the PPF: Bowed Outward

    Indicates increasing opportunity cost; producing more of one good costs increasingly more of the other.

  • Shape of the PPF: Straight Line

    Indicates constant opportunity cost; tradeoff between goods is constant.

  • Production Efficiency

    When we cannot produce more of one good without producing less of another; any point on the PPF.

  • Allocative Efficiency

    When we cannot produce more of any good without giving up something we value more highly; occurs where marginal benefit equals marginal cost (MB = MC).

  • Marginal Cost (MC)

    The opportunity cost of producing one more unit of a good; generally rises as production increases.

  • Marginal Benefit (MB)

    The benefit from consuming one more unit of a good, measured by willingness to pay; decreases as quantity consumed increases.

  • Principle of Decreasing Marginal Benefit

    The more of a good we have, the smaller the marginal benefit and the less we are willing to pay for an additional unit.

  • Economic Growth

    The outward shift of the PPF, representing an increase in production possibilities and standard of living.

  • Key Sources of Economic Growth

    Technological change and capital accumulation (including human capital).

  • Opportunity Cost of Economic Growth

    Less current consumption because resources are used for research, development, and capital formation.

  • Opportunity Cost Calculation

    Opportunity cost of good X = amount of good Y given up ÷ extra units of X gained, ignoring the minus sign.

  • Opportunity Cost as a Ratio

    If 1 pizza costs 5 cans of cola, then 1 can of cola costs \(\frac{1}{5}\) pizza.

  • Using Resources Efficiently

    All points on the PPF are efficient; choosing among them requires comparing costs and benefits.

  • Preferences in Microeconomics

    A description of likes and dislikes, represented by the marginal benefit curve.

  • Marginal Benefit Curve

    Shows the relationship between the marginal benefit of a good and the quantity consumed; downward sloping.

  • Tradeoff in Moving Along the PPF

    Increasing production of one good requires sacrificing some amount of another good.

  • Effect of Technological Change on PPF

    Shifts the entire PPF outward, increasing production possibilities for all goods.

  • Effect of a Good Weather Event on PPF

    Shifts only the intercept of the affected good outward, leaving the other intercept unchanged.
