Plain-text version
Two firms produce the same commodity; quantities x₁,x₂, total X=x₁+x₂. Inverse demand is P=a-bX. Firms have constant average costs c₁,c₂. Assume b>0, 0<c₁<c₂<a and a+c₁>2c₂. In a Cournot equilibrium, (A) firm 1 has the larger market share and the larger profit (B) firm 2 has the larger market share and the larger profit (C) firm 1 has the larger market share and the smaller profit (D) firm 2 has the larger market share and the smaller profit
Also written as: Two firms produce the same commodity; quantities x_1,x_2, total X=x_1+x_2. Inverse demand is P=a-bX. Firms have constant average costs c_1,c_2. Assume b>0, 0<c_1<c_2<a and a+c_1>2c_2. In a Cournot equilibrium,
