Demand and Elasticity Linear demand curve: Q = a – bP Elasticity: E d = (ΔQ/ΔP)/(P/Q) = -b(P/Q) E d = -1 in the middle of demand curve (up is more elastic) Total revenue and Elasticity: Elastic: Ed < -1 ↑P→↓R (↑P by 15%→↓Q by 20%) Inelastic: 0 > Ed > -1 ↑P→↑R (↑P by 15%→↓Q by 3%) Unit elastic: Ed = -1 R remains the same (↑P by 15%→↓Q by 15%) MR: positive expansion effect (P(Q) – sell of additional units) + price reduction effect (reduces revenues because of lower price (ΔP/ΔQ)/Q)
