What is Complementary Good

In economics, a complementary good is a good whose appeal increases with the popularity of its complement. Technically, it displays a negative cross elasticity of demand and that demand for it increases when the price of another good decreases. If  is a complement to , an increase in the price of  will result in a negative movement along the demand curve of  and cause the demand curve for  to shift inward; less of each good will be demanded. Conversely, a decrease in the price of  will result in a positive movement along the demand curve of  and cause the demand curve of  to shift outward; more of each good will be demanded. This is in contrast to a substitute good, whose demand decreases when its substitute's price decreases.
