Find the Nash equilibria of this game by considering all possibilities. Explain your answer fully.
The monopolist sets MC=MR for profit maximization
MC=20
MR = 100-8Q
MC=MR
100-8Q =20
80=8Q
Q= 80/8 = 10
P = 100-4(10) = 60
Whereas setting P=MC, the firm will produce 100-4Q=20
Q= 20
P = 20
So, DWL = 0.5*(20-10)*(60-20) = 5*40 = 200
b):- The monopoly pricing strategy makes a deadweight loss since it produces a lower quantity at a more significant expense than the efficient quantity.
A perfect price discriminating monopolist would set P = MC and capture all the consumer surplus and the deadweight loss by producing the efficient quantity and as there is no adjustment in the efficient quantity, there would be no deadweight loss in the market.
Condition 1:
If player 1 chooses I, then player 2 will choose I as it gives him a higher pay-off of 1 as compared to 0.
Condition 2:
If player 1 chooses A, then player 2 will choose A as it gives him a higher pay-off of 2 as compared to 0.
Condition 3:
If player 2 chooses I, then player 1 will choose I as it gives him a higher pay-off of 2 as compared to 0.
Condition 4:
If player 2 chooses A, then player 1 will choose A as it gives him a higher pay-off of 1 as compared to 0.
So, (2,1) and (1,2) are the nash equilibrium in this case.
