Substitute goods: an increase in the price of
one product leads to an increase in the
quantity demanded of a cheaper, similar
product
Complementary goods: A decrease in the price
of one leads to an increase in the quantity
demanded of the other.
substitute good Examples:
Tea (for coffee)
Ford (for Toyota)
Gap (for Abercrombie)
Skippy peanut butter (instead of Jiff)
Underarmour (Northface)
Pepsi (coke)
**This is why companies offer coupons/sale
prices!! Increase demand over competition!**
Complementary good Examples:
Hot dogs and buns
Pencils and erasers
DVD players and DVDS
Toothbrushes and toothpaste
Printers and toner cartridges
**One is not good without the other. If there’s
a sale on hot dogs, people will automatically
demand buns**
