Question 1

+2 marksOne correct option

Consider a duopoly game in which two firms simultaneously and independently select prices that are greater than or equal to zero. Denote firm 1's price as P1P_1 and firm 2's price as P2P_2.

After the prices are set, consumers demand 10−P1+P210 - P_1 + P_2 units of the good that firm 1 produces, and they demand 10−P2+P110 - P_2 + P_1 units of the good that firm 2 produces. Assume that each firm produces at zero cost, so firm ii's payoff (profit) is (10−Pi+Pj)Pi(10 - P_i + P_j)P_i, where PiP_i is firm ii's price and PjP_j is the other firm's price.
