Supply is the amount of a good or service that is available to consumers. The price a consumer will pay for a good determines how much of the good’s supply is sold. In this way, consumers are able to influence prices through their demand. As consumers buy up the supply of a product without decreasing their demand, the price increases. At some point, price becomes too high, and demand falls.
Equilibrium occurs when supply and demand are equal. From the above example, as the price falls, demand increases. Eventually, the market determines the right price, and fluctuation between supply and demand slows. This is where the market begins to meet equilibrium.
