    Supply

    • The quantity of goods that a seller is willing to offer for sale.

    Market Types

    • Goods Market: Where consumers buy goods.

      • More money, more goods can be bought.
    • Substitution Effect: Change in price of a good that changes demand because of alternative consumption of substitute goods.
      • Buying cheaper goods instead of expensive ones.

    The Law of Demand

    • As price increases, the quantity demanded decreases.

    Equilibrium Quantity

    • The quantity of products that both buyers and sellers agree to transact at a specific price.

    Market Equilibrium

    Computation Practices

    • Steps to determine equilibrium price and quantity:
      • Compute the demand and supply schedules.
      • Graph the demand and supply curves.
      • Compute the equilibrium price and quantity.

    Saving and Investment

    • Saving: Setting aside a portion of current income for future use.
    • Investment: Building up capital stock for more future production and consumption.
