GATE 2024 Question 58: Monopolistic competition and oligopoly

An industry comprising only two firms produces a homogenous product where the market demand function is given by P=200−2(q1+q2)P=200-2(q_1+q_2)P=200−2(q1​+q2​) where q1q_1q1​ and q2q_2q2​ are the output levels of firm 1 and firm 2, respectively. The individual firm's cost functions are TC1=4q1TC_1=4q_1TC1​=4q1​ and TC2=4q2TC_2=4q_2TC2​=4q2​, where TC1TC_1TC1​ and TC2TC_2TC2​ are total costs of firm 1 and 2, respectively. If firm 2 is a Stackelberg Leader, and firm 1 is a Follower, then the profit of the Stackelberg Leader will be ______ (rounded off to two decimal places).

Plain-text version

An industry comprising only two firms produces a homogenous product where the market demand function is given by P=200-2(q₁+q₂) where q₁ and q₂ are the output levels of firm 1 and firm 2, respectively. The individual firm's cost functions are TC₁=4q₁ and TC₂=4q₂, where TC₁ and TC₂ are total costs of firm 1 and 2, respectively. If firm 2 is a Stackelberg Leader, and firm 1 is a Follower, then the profit of the Stackelberg Leader will be (rounded off to two decimal places).

Also written as: An industry comprising only two firms produces a homogenous product where the market demand function is given by P=200-2(q_1+q_2) where q_1 and q_2 are the output levels of firm 1 and firm 2, respectively. The individual firm's cost functions are TC_1=4q_1 and TC_2=4q_2, where TC_1 and TC_2 are total costs of firm 1 and 2, respectively. If firm 2 is a Stackelberg Leader, and firm 1 is a Follower, then the profit of the Stackelberg Leader will be (rounded off to two decimal places).
