The law of demand tells us that more of good A will be purchased by moving down the demand curve. Peanut butter and jelly is a good example of symmetric complements — they have comparable price points, and both generally can be improved by purchase of the other.

Thus entered substitute and complementary products into the world of economics and pricing. To get a complete list for any product might be time consuming and difficult, but it is not necessary because we want to focus on the relationship between price and the quantity of a product that people are willing to buy during some interval of time.

Indifference curve for perfect complements A perfect complement is a good that has to be consumed with another good. The value you get from the original product would be increased by the purchase of a complementary product e. The fact that one good is substitutable for another has immediate economic consequences: Complementary goods Here we have the demand curves for two complementary goods A and B.

A baking cookbook is a good complementary product for a customer purchasing a stand-mixer a key appliance for baking. The supply and demand of cars is represented by the figure at the right with the initial demand D1.
