A monopolist sells the same product in two geographically separated markets, at price P1P_1P1​ in market 1 and at price P2P_2P2​ in market 2. It is known that P1=2P2P_1=2P_2P1​=2P2​. Denote the price elasticities of demand for the product in market 1 and market 2 by e1e_1e1​ and e2e_2e2​ respectively. Note that the common marginal cost of manufacturing the good is positive. Then which of the following could be true?

Plain-text version

A monopolist sells the same product in two geographically separated markets, at price P₁ in market 1 and at price P₂ in market 2. It is known that P₁=2P₂. Denote the price elasticities of demand for the product in market 1 and market 2 by e₁ and e₂ respectively. Note that the common marginal cost of manufacturing the good is positive. Then which of the following could be true? (A) e₁ = 1/2, e₂ = 1/2 (B) e₁=3/2, e₂ = 3 (C) e₁ = 3, e₂ = 5 (D) e₁= 1, e₂ = 1
