Does Supply and Demand Work?

There is an inverse relationship between the supply and prices of goods and services when demand is unchanged. If there is an increase in supply for goods and services while demand remains the same, prices tend to fall to a lower equilibrium price and a higher equilibrium quantity of goods and services.

Does supply and demand always work?

The supply and demand model is a static model; it is always in equilibrium, because it is closed with an equilibrium condition. Further, the model is supposed to represent a perfectly competitive market and so price adjustment by firms and households is precluded by assumption.

How does supply and demand actually work?

The law of demand says that at higher prices, buyers will demand less of an economic good. The law of supply says that at higher prices, sellers will supply more of an economic good. These two laws interact to determine the actual market prices and volume of goods that are traded on a market.
