elasticity of demand Flashcards
What is P.E.D?
Price elasticity of demand
What does price elasticity of demand measure?
how responsive demand is to changes in price
What is a elastic product?
larger changes and demand is responsive
What is a inelastic product?
smaller change and demand isn’t responsive
What is a elastic demand curve?
a demand curve is elastic when a percentage change in price results in a proportionally larger percentage change in quantity demand
What does a inelastic graph look like?
straight-ish line
What does a elastic graph look like?
flatter line
What are examples of elastic products?
tickets, vehicles, TV, airplanes flights, luxury
What are examples on inelastic products?
petrol, basic items, essentials, tobacco, habitual substances
What is the formula for P.E.D?
percentage change in demand / percentage change in price
What happen when PED = 0
Perfectly inelastic
What happens when PED > 1
Elastic
What happens when PED < 1
Inelastic
What happens when PED = infinity
Perfectly elastic
What happens when PED = 1
unitary (no change in demand when price changes)
