Introduction

Define key terms: Consumer Surplus, Producer Surplus.
Brief overview of how price changes affect these surpluses.

Section	Content	Analysis Points	Evaluation Points
Impact on Consumer Surplus	- Explain Consumer Surplus (CS) as the difference between what consumers are willing to pay and what they actually pay. -Illustrate with a supply and demand diagram. -Discuss how an increase in price reduces CS.	- Higher prices lead to a decrease in quantity demanded, reducing CS. -A shift in the demand curve due to price change will alter the CS area.	- Impact on CS can vary depending on the elasticity of demand. -Consider the long-term vs. short-term effects.
Impact on Producer Surplus	- Define Producer Surplus (PS) as the difference between the price producers receive and the minimum price they are willing to accept. -Illustrate with a supply and demand diagram. -Discuss how an increase in price increases PS.	- Higher prices increase PS by increasing the difference between the price received and the marginal cost of production. -Diagram can show the expansion of PS area.	- The extent of PS increase depends on the elasticity of supply. -Consider the potential for cost changes in the long run.
Overall Market Effects	- Combine the impacts on both CS and PS. -Discuss how market equilibrium changes with price alterations. -Use diagrams to show shifts in surplus areas.	- A rise in price generally increases PS but decreases CS. -Changes in market equilibrium affect total welfare.	- Consider the distribution of surplus changes among different groups (consumers vs. producers). -Potential welfare losses or gains in different market conditions.
Policy Implications	- Discuss the role of government intervention, such as price floors and ceilings. -How these policies impact CS and PS.	- Price floors (minimum prices) may lead to excess supply, impacting PS positively but reducing CS. -Price ceilings (maximum prices) may lead to shortages, reducing PS but increasing CS.	- Evaluate the effectiveness of such policies in achieving the desired outcomes. -Consider unintended consequences.

Conclusion

Summarize key points on how price changes impact consumer and producer surplus.
Reflect on the overall implications for market efficiency and welfare.
Consider any limitations or assumptions in the analysis.

Top 3 Tips for Scoring 40/40

Tip Number	Tip
1	Use Diagrams Effectively - Incorporate clear, accurate supply and demand diagrams to visually illustrate changes in consumer and producer surplus. - Ensure diagrams are well-labelled and explained in detail.
2	Integrate Elasticity - Discuss how the elasticity of demand and supply affects the magnitude of changes in consumer and producer surplus. - Explain that elasticity influences the extent of surplus changes.
3	Critical Evaluation - Provide a balanced evaluation by considering various perspectives, such as long-term vs. short-term effects, different market conditions, and the impact of government interventions. - Highlight both positive and negative outcomes. - Support arguments with real-world examples where possible.
