Lesson Plan

• Describe allocative, productive, and dynamic efficiency and how they differ across market structures.
• Compare perfect competition, monopoly, monopolistic competition, and oligopoly in terms of efficiency and dead‑weight loss.
• Analyse how profit incentives influence innovation and dynamic efficiency in each structure.
• Apply efficiency concepts to evaluate real‑world market examples.

• Projector and screen
• Whiteboard and markers
• Handout with comparative efficiency table
• Graph paper and calculators
• Case‑study sheets (e.g., telecom oligopoly)
• Sticky notes for group activity

Begin with a quick poll: “Which market structure do you think is most efficient and why?” Connect responses to prior knowledge of P=MC and P=minATC. Outline today’s success criteria – students will be able to identify and compare the three types of efficiency across the four main market structures.

1. Do‑now (5') – Short quiz on allocative and productive efficiency definitions.
2. Mini‑lecture (15') – Present key concepts and the comparative table using the projector.
3. Guided group analysis (20') – Teams complete a worksheet rating each market structure on allocative, productive, dynamic efficiency and DWL.
4. Whole‑class debrief (10') – Groups share findings; teacher highlights misconceptions.
5. Diagram activity (10') – Students sketch a monopoly DWL triangle and label efficiency outcomes.
6. Check for understanding (5') – Exit ticket: “Which market structure achieves all three efficiencies and why?”

Summarise that perfect competition uniquely attains both allocative and productive efficiency, while other structures trade off efficiency for innovation potential. Collect exit tickets to gauge understanding and assign a brief homework: analyse a real‑world industry and classify its efficiency profile.
