USA National Standards for Concept "Supply"

NATIONAL STANDARD 8 - ROLE OF PRICES: Students will understand that: Prices send signals and provide incentives to buyers and sellers. When supply or demand changes, market prices adjust, affecting incentives.

Students will be able to use this knowledge to: Predict how prices change when the number of buyers or sellers in a market changes, and explain how the incentives facing individual buyers and sellers are affected.

Understanding the role of prices as signals and incentives helps people anticipate market opportunities and make better choices as producers and consumers. It also helps citizens understand the consequences and weigh the costs and benefits of price controls, such as minimum-wage laws and rent ceilings, that set legal minimum or maximum prices and result in sustained surpluses or shortages.
