In a market economy, competition occurs between large numbers of buyers and sellers who vie for the opportunity to buy or sell goods and services. The competition among buyers means that prices will never fall very low, and the competition among sellers means that prices will never rise very high. This is only true if there are so many buyers and sellers that none of them has a significant impact on the market equilibrium.
Demand refers to the amount of goods and services that buyers are willing to purchase. Typically, demand decreases with increases in price, this trend can be graphically represented with a demand curve. Demand can be affected by changes in income, changes in price, and changes in relative price.
The price of a good or service at which quantity supplied is equal to quantity demanded. Also called the market-clearing price.
