In microeconomics, surplus refers to the difference between what consumers are willing to pay for a good or service (consumer surplus) and the market price, or the difference between what producers are willing to accept for a good or service and the market price (producer surplus). Welfare effects analyze how different market structures or government interventions impact these surpluses and overall social welfare. Understanding these concepts is crucial for evaluating the efficiency and equity of economic policies.

| Term | Definition |

| 1. Consumer Surplus | A. The total benefit to society from an economic activity. |

| 3. Deadweight Loss | C. The amount a seller is paid minus the cost of production. |
| 4. Social Welfare | D. The loss of economic efficiency that occurs when equilibrium is not achieved or is not Pareto optimal. |
| 5. Market Failure | E. The difference between the maximum price a consumer is willing to pay and the actual price they do pay. |
