1 If the demand increases, and the supply remains the same, there will be a shortage. 2  This will mean the price will increase. 3  If the demand decreases, and the supply remains the same, there will be a surplus. 4  This will mean the price will go down.
As the demand curve shifts the change in the equilibrium price and quantity will be in the same direction, i.e., both will increase. If the supply curve shifts left, say due to an increase in the price of the resources used to make the product, there is a lower quantity supplied at each price.
