Consider a price competition model with two firms, 1 and 2, whose demand functions are as follows:

Q1 =48−3P1 +2P2 Q2 =80−4P2 +3P1

Each firm incurs costs; C1(Q1) = 8Q1 and C2(Q2) = 13Q2.

a) Write down firms 1’s and 2’s profit functions.

b) Compute and graph firms 1’s and 2’s best response functions as a function of the other firm’s prices.

c) Find the Nash equilibrium of the game.
d) Calculate the profit of each firm in the Nash equilibrium.

Consider two identical firms in a Cournot competition. The market demand is P = a – bQ. TC1 = cq1 = TC2 = cq2 . Find the profit function of firm 1. Maximize the profit function to find the reaction function of firm 1. Solve for the Cournot-Nash Equilibrium. Carefully discuss how the slope of the demand curve affects outputs and price.

QUESTION 1 Two firms compete by choosing price. Their demand functions are Q1 = 20 - P1 +P2 and Q2 = 20 - P2 +P1 where P1 and P2 are the prices charged by each firm, respectively, and Q1 and Q2 are the resulting demands. Note that the demand for each good depends only on the difference in prices; if the two firms colluded and set the same price, they could make that price as high as they wanted, and...

Two firms, 1 and 2, are engaged in Bertrand price competition. There are10possible buyers, each of whom is willing to pay up to $4, and no more, for an item the firms sell .Firms 1 and 2 have identical unit costs of $2. However, each firm has a capacity of 8units, so that it cannot satisfy the whole market by itself (it can only satisfy 8 possible buyers, at most).The firms simultaneously announce prices, p1 and p2 respectively and the...

Consider the Hotelling model of the competition between two firms. They must choose to set up business on a line (=1). Select all that apply. (PLEASE EXPLAIN ANSWERS COMPLETELY) a. If both firms are localized in position 1/2 (i.e., center of the line), neither firm has incentives to deviate and move to a different position. b.

8.6 Investment in the Future:   Consider two firms that play a Cournot competition game with demand p = 100 − q and costs for each firm given by ci(qi) = 10qi . Imagine that before the two firms play the Cournot game firm1 can invest in cost reduction.   If it invests the costs of firm 1 will drop to c1(q1) = 5q1. The cost of investment is F >0. Firm 2 does not have this investment opportunity.           a.  ...
