The market demand curve is Q = 38 -P. There are two firms: firm1 and firm 2. One has MC=2 and the other has MC= 5. They choose outputs simultaneously (the cournot model).
A) Find an equation for 1's reaction curve
B) Find an equation for 2's reaction curve
C) Plot both curves on a diagram with firm 1's output on the horizontal axis and firm 2's ouput on the vertical axis.
D) What output is chosen in equilibrium
E) Calculate dwl in the Cournot model
F) Show the reaction curves when one firm has MC=3 and the other MC=10
