Verified step by step guidance1
Step 1: Understand the concept of total surplus in microeconomics. Total surplus is the sum of consumer surplus and producer surplus, representing the overall net benefit to society from the production and consumption of a good.
Step 2: Recall that consumer surplus is the area between the demand curve and the equilibrium price, up to the equilibrium quantity. This area represents the difference between what consumers are willing to pay and what they actually pay.
Step 3: Recall that producer surplus is the area between the supply curve and the equilibrium price, up to the equilibrium quantity. This area represents the difference between the price producers receive and their minimum acceptable price.
Step 4: Combine these two surpluses to find total surplus. Graphically, total surplus is the area between the demand curve and the supply curve, from the origin (zero quantity) up to the equilibrium quantity.
Step 5: Therefore, the total surplus corresponds to the entire area bounded above by the demand curve, below by the supply curve, and vertically by the equilibrium quantity.
