Study Notes

Complementary Goods

  • A complementary good is a product that works or partners with another good.
  • If one of the two products undergoes a price increase, both products' demands will decrease.
  • Examples of complementary goods include key and lock, or printer and ink.

Income and Demand

  • An increase in income will shift the demand curve to the right.
  • Determinants of demand include price, income, taste and preferences, population, price/consumer expectation, and price of related goods.

Law of Supply

  • There is a direct relationship between price and quantity supplied.
  • The supply curve slopes upward to the right.
  • As price increases, supply will also increase.

Determinants of Supply

  • Price is considered first to determine profitability.
  • Non-price determinants include:
    • Taxes: An increase in taxes will decrease supply.
    • Subsidy: A government grant to assist an industry or business.
    • Weather: Good weather can increase supply, while bad weather can lead to shortages.
    • Technology: Upgrading technology can increase supply.
    • Producer's expectation: Expecting higher prices in the future may lead to hoarding products.
    • Price of related goods: Similar to the demand.
    • Number of sellers or producers: An increase in sellers or producers can lead to a profit.

Taxes

  • Taxes are a government revenue that comes from households and firms.
  • Types of taxes include:
    • Tax stamp (Buwis): Found in cigarettes, alcohol, etc.
    • Donor's tax: A tax on a donation or gift.

Subsidy

  • A subsidy is a sum of money granted to assist an industry or business.
  • Subsidy can help keep prices low or competitive.

Technology

  • Technology can help produce more goods and services.
  • It is used for marketing, advertisements, feedback, and producing more services.

Changes in Demand

  • A shift to the right on the demand curve indicates an increase in quantity.
  • A shift to the left on the demand curve indicates a decrease in quantity.
  • Y-axis represents price, while X-axis represents quantity.
