Supply and demand , in economics , relationship between the quantity of a commodity that producers wish to sell at various prices and the quantity that consumers wish to buy. It is the main model of price determination used in economic theory. The price of a commodity is determined by the interaction of supply and demand in a market. The resulting price is referred to as the equilibrium price and represents an agreement between producers and consumers of the good. In equilibrium the quantity of a good supplied by producers equals the quantity demanded by consumers. The quantity of a commodity demanded depends on the price of that commodity and potentially on many other factors, such as the prices of other commodities, the incomes and preferences of consumers, and seasonal effects. In basic economic analysis, all factors except the price of the commodity are often held constant; the analysis then involves examining the relationship between various price levels and the maximum quantity that would potentially be purchased by consumers at each of those prices.

In the short run, output fluctuates with shifts in either aggregate supply or aggregate demand; in the long run, only aggregate supply affects output. In economics, output is the quantity of goods and services produced in a given time period. The level of output is determined by both the aggregate supply and aggregate demand within an economy. National output is what makes a country rich, not large amounts of money. For this reason, understanding the fluctuations in economic output is critical for long term growth. There are a series of factors that influence fluctuations in economic output including increases in growth and inputs in factors of production. Anything that causes labor, capital, or efficiency to go up or down results in fluctuations in economic output.

It postulates that, holding all else equal , in a competitive market , the unit price for a particular good , or other traded item such as labor or liquid financial assets, will vary until it settles at a point where the quantity demanded at the current price will equal the quantity supplied at the current price , resulting in an economic equilibrium for price and quantity transacted.

The law of supply and demand , one of the most basic economic laws, ties into almost all economic principles in some way.

Economic theory suggests that, in a free market there will be a single price which brings demand and supply into balance, called equilibrium price.
