Demonstrate understanding of the efficiency of market equilibrium
This standard asks you to show you understand when markets work efficiently and when government changes like taxes, tariffs, or subsidies affect how well they work. You'll explain how these policies change who wins and who loses (consumers, producers, government), and whether the overall outcome is good for society. You need to use supply and demand graphs to show what happens and back up your explanations with specific references to the data.
You identify that consumer or producer surplus changed and give one reason why, but you may not reference the graph or apply definitions to the context.
You explain how both consumer and producer surplus changed, reference specific points on the graph, correctly distinguish between demand and quantity demanded, and use concepts like affordability and profitability to explain why.
You show how price and quantity changes offset each other to affect consumer surplus and producer surplus, fully integrate detailed graph references with anchor points, and use accurate economic terminology throughout a comprehensive explanation.
