What is price elasticity of demand?
Economics
ScanSolve AI Answer
Price elasticity of demand measures how much quantity demanded changes when price changes. Formula: PED = % change in quantity demanded / % change in price. Elastic (PED > 1): demand is very responsive to price changes (luxury goods). Inelastic (PED < 1): demand barely changes with price (necessities like insulin, gasoline). Unit elastic (PED = 1): proportional change. Factors: availability of substitutes, necessity vs luxury, time horizon, proportion of income spent.
