Demand, Supply and Elasticity
Market equilibrium, shifts, price controls, elasticity and revenue consequences.
How to study the CIMA Certificate
Secure each subject's concepts and calculations before using short business scenarios for application. Static study assets do not reproduce every computer-marked interaction or combine the four subjects into one official examination.
Core concepts
Concept 1
Distinguish movements along curves from shifts.
Exam cue: Name the changed non-price determinant.
Concept 2
Calculate and interpret elasticity.
Exam cue: Use percentage changes consistently.
Concept 3
Connect elasticity with pricing and total revenue.
Exam cue: Check whether demand is elastic, unit elastic or inelastic.
Risk pitfalls and guardrails
Calling a price-driven movement a demand shift.
Guardrail: Do not combine subjects, treat the 0-150 scale as a percentage, or rely on a remembered label without checking timing, units, assumptions and facts.
Ignoring the sign convention for demand elasticity.
Guardrail: Do not combine subjects, treat the 0-150 scale as a percentage, or rely on a remembered label without checking timing, units, assumptions and facts.
Assuming a price rise raises revenue in every market.
Guardrail: Do not combine subjects, treat the 0-150 scale as a percentage, or rely on a remembered label without checking timing, units, assumptions and facts.
Memory anchors
Demand shift
A non-price determinant changes demand at each possible price.
Elastic demand
Demand is price elastic when quantity responds proportionately more than price.
Equilibrium
Market equilibrium occurs where quantity demanded equals quantity supplied.
Checkpoint rule
Do the check-up only after you can summarize each concept in one sentence and identify one dangerous pitfall from memory.
