Chap 2: Elasticity- Price Elasticity of Supply 2. Chap 3: Consumer Behavior- Consumer Preferences 1 Price Elasticity of Supply Price elasticity of supply. The percentage change in quantity supplied re- sulting from one percentage change in price. dQ S E P S = Q S = P dQ S . dP Q S dP P In the short run, if price increases, firms will want to produce more but cannot hire workers and buy machines immediately, thus the supply is less elastic. In contrast, supply is more elastic in the long run. Example (Example in Elasticities of Demand) . Assume the quantity demanded is Q D = 14 3 P + I + 2 P S P C . P- Price I- Income P S- Price of substitute P C- Price of complement Calculate E P D , E I , E QP S and E QP C when P = 1, I = 10, P S = 2 and P C = 1. Solution: Given the values of variables, the quantity demanded is: Q D = 14 3 1 + 10 + 2 2 1 = 24 . Cite as: Chia-Hui Chen, course materials for 14.01 Principles...
