What economic principle states that as supply increases, the price of goods decreases?

The principle that states that as supply increases, the price of goods decreases is the Law of Supply. This law indicates that, all else being equal, a higher quantity of a good or service will be supplied at a lower price. This relationship occurs because suppliers are generally willing to produce and sell more of a good as its price increases, given the potential for higher revenue. Conversely, when the supply of a good goes up, the market is saturated with that good, leading to a decrease in its price as sellers compete to attract buyers.

Understanding this principle is crucial in economic theory as it helps predict how supply changes affect market prices. For instance, if a new technology significantly reduces production costs, companies may produce and supply more of a product, expecting that the increase in supply could push prices down as competition among suppliers intensifies to sell their goods. This interaction between supply and price helps shape market dynamics and consumer behavior.
