Why are prices important? Prof. Daniel J. Smith of Troy University describes the role that prices play in generating, gathering, and transmitting information throughout the economy. Information about the supply and demand of different goods are dispersed among different buyers and sellers in an economy.

Based on the simple information contained in a price, people adjust their behavior to account for conditions in supply and demand, even if they are unaware of that information.
