Price elasticity of demand - answer✔Measure of how responsive quantity demanded is to
changes in price
Price elasticity of demand (e) = (% change in quantity demanded) / (% change in price)
if absolute value of e is >1 then demand is elastic
if absolute value of e is <1 then demand is inelastic
Estimated price elasticity = [(Qt-Q2)/(Q1+Q2)] / i(P1-P2)/(P1+P2)]
this equation is used to estimate demand from a price and quantity change
