Assume:
a. Market demand: P = 100 -.5Q1 - .5 Q2
b. TC1 = 4Q1 and TC2 = .25Q22
Make sure you show me all of your computations (TR, TC, and your partial derivatives).
You will be using the same data for the Cournot and Cartel problem. Find the quantities for both firms in both market types that maxes profit. As a stretch question how much profit does each Cournot firm make and what is the joint profit for the cartel.
1) Cournot competition is choosing simoultaneous quantity model.
profit (П1) = total revenue (P.Q1) - total cost (TC1)
П1= (100- 0.5Q1- 0.5Q2)Q1 - 4Q1 .............(1)
similarly, П2 = (100- 0.5Q1- 0.5Q2)Q2 - 0.25Q22 ...............(2)
Partial differentiating equation (1) w.r.t Q1 and equation (2) w.r.t Q2 we get as follows:
2) now for cartel both firm will collude and want to maximise the joint profit as follows:
max П (Q1, Q2) = P.(Q1+Q2) - TC1 - TC2
we get;
