Explanation:

In a competitive economy, the balance between supply and goods and services occurs when demand and supply match. However, situations of oversupply or scarcity tend to alter the parameters of the demand and supply curves. If shortages occur, the price tends to rise, which generates an incentive for production. If oversupply occurs, the price tends to decrease, which is an incentive to increase demand. Thus, suplus or shortages will alter the quantity demanded / offered to cause a rearrangement of these parameters until the economy finds a new equilibrium point.
