Seinfeld Economics: The Sponge (Searching)

by Linda Ghent

A change in demand is a shift in the demand curve. It may be caused by many factors, but not a change in the price of the good. An increase in demand shifts the demand curve to the right, while a decrease in demand shifts the demand curve to the left.

Expectations can cause a change in demand. For example, if a consumer believes that the price of a good will rise in the future, he will buy more of it today.
