What do we call the price that effectively "clears the market"?

The price that effectively "clears the market" is referred to as the equilibrium price. This is the price at which the quantity of goods supplied equals the quantity of goods demanded. In other words, at this price, there is no surplus or shortage of goods in the market. When the market is at equilibrium, consumers are able to purchase all the goods they want at this price, and producers can sell all they are willing to offer, resulting in a stable market condition.

Market price typically refers to the current price at which goods are being traded, which can fluctuate due to changes in supply and demand. Demand price and supply price relate to the prices at which consumers are willing to buy and producers are willing to sell, respectively, but they do not specifically indicate the point at which the market clears. The equilibrium price is thus the critical point in a market context where forces of supply and demand are balanced.
