Consider a duopoly where two firms X and Y compete over quantities. They make their output decisions simultaneously. The firms have the same cost function which reads:
TCi = 100+50qi
where TCi are total cost in dollar and qi is the quantity produced by each firm. The total output in the industry is given by Q = qx +qy , the inverse demand function reads:
P(Q) = 350?2Q
1.Calculate the reaction functions of both firms and find the optimal level of output in the Cournot-Nash equilibrium.
2.How much will firm X produce if Y produces 30 units?
3.Illustrate your solution in a suitable graph.
4.If firm 1 chooses quantity first and firm 2 choose quantity after observing firm 1’s choice, find the Stackelberg leader equilibrium.
5.If the two firms collude, find the price and outputs.
