A quick look at the chapter from our IB Diploma Economics notes. The full chapter notes have the detailed explanations, diagrams and practice questions with answers.
Topics in this chapter
- What you must be able to do
- Demand and supply forming a market equilibrium AO4
- Disequilibrium: excess demand and excess supply AO2 AO4
- How the price mechanism restores equilibrium
- Shifting demand and supply: a new equilibrium AO2 AO4
- Functions of the price mechanism AO2
- When both curves shift
- Consumer, producer and community surplus AO2 AO4
- Calculation: consumer and producer surplus from a diagram
- Allocative efficiency at the competitive equilibrium AO2 AO4
“I can” checklist: what you must be able to do
- I can draw and explain a market equilibrium and calculate it from equations.
- I can show excess demand and excess supply and explain how price adjusts.
- I can shift demand or supply, find the new equilibrium, and explain the changes with a diagram.
- I can explain the functions of the price mechanism: signalling, incentive and rationing.
- I can draw consumer, producer and community surplus and explain why community surplus is maximised at equilibrium.
- I can explain allocative efficiency using MB = MC and show loss of surplus away from equilibrium.
- HL: I can calculate consumer surplus and producer surplus from a diagram, and the loss of surplus when output is below or above equilibrium.
