Price Elasticity of Demand Flashcards
What is price elasticity of demand?
PED- responsiveness in demand for 🚘- due to change in its price
What is price elastic demand?
Demand is said to be price elastic when a change in price causes a proportionately larger change in demand
What is price inelastic demand?
Demand is said to be price inelastic when a change in price causes a proportionately smaller change in demand
How do you calculate the price elasticity of demand?
PED= % change in quantity demanded of good A/% change in price of good A
What is unique about all PED values?
They are always negative
State what the PED values say about the elasticity of the good
Less than -1= Elastic Between 0 & -1= Inelastic Equal to -1= Unitary/Unit elasticity Equal to 0= Perfectly Inelastic PED infinite ♾= Perfectly Elastic
What are the determinants/conditions of Price Elasticity of Demand:
1) Number of substitutes- ⬆️ substitutes = ⬆️ price elasticity of demand- ⬆️ alternatives encourage switching
2) Necessity/Luxury- if product necessity then demand = ⬆️ price inelastic- people require product no matter the price
If product luxury then demand = price elastic- people ✖️ need product … can live without it if price ⬆️
3) Addictiveness 🚬 -⬆️ addictive product = ⬆️ price inelastic demand- need product to fulfil addiction
4) Time ⏰- time allows consumers to find alternatives … ⬆️⏰ = ⬆️ price elastic demand
5) Proportion of income spent on the good- ⬆️ proportion of income = ⬆️ price elastic- can not afford any price increases
6) Brand image🥤- strong brand image e.g. Coca Cola 🥤 or Levi 👖 = ⬆️ price inelastic- consumers willing to pay a premium 💵 price
