A fundamental economics theory known as the law of supply asserts that, subject to all other factors remaining equal, as the price of a commodity or service rises, so does the quantity supplied of that good or service. In contrast, when a good or service's price drops, so does the amount that is made available.


The law of supply assumes that producers are motivated by profit. When the price of a good or service rises, producers have the incentive to increase production to earn more profits. This results in an increase in the quantity supplied.

As a good or service's price drops, however, manufacturers may decide to scale back their output or shift their focus to other lucrative products. As a result, less of the commodity or service is provided in total quantity.

In microeconomics, the law of supply is a fundamental idea that is used to examine producer behavior and the effects of price changes on the market. It is crucial to remember that the law of supply makes the assumption that all other elements influencing supply, such as production costs, technological advancements, and governmental laws, would remain constant.

The law of supply is a practical tool that explains to businesses and decision-makers how changes in prices will impact the supply of goods and services. Businesses might boost production to benefit from higher pricing, for instance, while politicians might employ subsidies or restrictions to promote or inhibit the production of specific commodities or services.
