Consumer Welfare and Policy Analysis

• Refers to the overall well-being and satisfaction that consumers derive from the consumption of goods and services.

Compensated and Uncompensated Consumer Welfare

• Compensated consumer welfare measures the change in welfare from a price change while holding the consumer’s utility constant.
• Uncompensated consumer welfare measures the difference between what consumers are willing to pay for a good and what they actually pay, based on observed market behavior.

Welfare Economics

• Represents the difference between what consumers are willing to pay for a good or service and what they actually pay.
• Measures the benefit buyers receive from participating in a market.
• The area below the demand curve and above the price measures the consumer surplus in a market.

Consumer Surplus and Market Efficiency

• Consumer surplus measures the benefit that buyers receive from a good as the buyers themselves perceive it.
• An allocation of resources that maximizes the sum of consumer and producer surplus is said to be efficient.
• The equilibrium of supply and demand maximizes the sum of consumer and producer surplus.
• The invisible hand of the marketplace leads buyers and sellers to allocate resources efficiently.

Equilibrium

• A situation in which the market price has reached the level at which quantity supplied equals quantity demanded.
• At the equilibrium price, the quantity of the good that buyers are willing and able to buy exactly balances the quantity that sellers are willing and able to sell.
