Unit 1: Basic Economic Concepts

(1.1) Scarcity

  • scarcity: products that are finite (have an end)

    • problem of economics: products are scarce but wants are unlimited → make choices and consider costs

  • 4 economic resources

    1. land: resources found in nature

      • payment = rent

    2. labor: all human effort

      • payment = wages

    3. capital: machinery/tools made by humans to gain resources

      • payment for use = interest

    4. entrepreneurship: innovation + ideas

      • payment: profit

    • NOT economic recources = consumer goods, waste, money/stocks (are used to facilitate production)

(1.2) Resource Allocation + Economic Systems

  • fundamental economic problem

    1. What will be produced?

    2. How will goods/services be produced?

    3. Who will get goods/services?

  • command economy: government makes decisions for who owns/produces

  • market economy: private individuals makes decisions for who owns/produces

    • creates competition between private individuals

  • traditional economy: cultural customs shape the economy

    • EX: indigenous communities using bartering and religious/cultural importance to certain goods

  • mixed economy: mix of command + market economy (private ownership with regulation)

    • most common economy in the world

  • households: consumers

  • firms: producers

  • allocation systems:

    • “first come, first serve”

    • random (lottery)

    • competition

    • command (based on need)

    • price (whoever can pay gets the good/service)

(1.3) Production Possibilities Curve

  • opportunity cost: how much X product is given up to produce Y product

    • equation = cost/gains

  • productions possibilities curve (PPC): conveys what society/factories are capable of producing with given resources

    • constant PPC: the production level stays the same → constant opp costs

    • increasing PPC: different resources → bowed out graph

      • the more technology → PPC bows out more to the right

      • most realistic PPC graph

(1.4) Comparative Advantage + Trade
