Answer the following question. Please show all your working/explanation.
Three firms compete a la Cournot (compete in a Cournot Competition). Each firm has constant marginal cost c. Inverse demand curve is 1 - Q, where Q is the total quantity. Firm 1 moves first, and chooses q1 . After firm 1 chooses q1, firms 2 and 3 move second and simultaneously choose q2 and q3 . Find the equilibrium quantities q1, q2, q3 .

Let us consider a market where 3 firms I = {1, 2, 3} compete `a la Cournot (quantity-setting competition). The inverse demand function is given by p(Q) = 300 − 5Q, where Q = q1 + q2 + q3. The cost function is homogeneous and it is C1(q) = C2(q) = C3(q) = 30q. Write explicitly the profit functions of each i ∈ I. Derive best reply functions and the Nash equilibrium of the game.

Problem 2. Cournot Competition with Three Firms Suppose there are three identical firms engaged in quantity competition. The demand is P = 1 - Q where Q = qi + q2 + q3. To simplify, assume that the marginal cost of production is zero. Compute the Cournot equilibrium (i.e., quantities, price, and profits)

3. There are two firms that compete according to Cournot competition. Firm 1 has a cost function G(91) = 5.59+12. Firm 2 has a cost function C(q2) = 2.5q3 + 18. These firms cannot discriminate, so there is just one price that is determined by the aggregate demand. The inverse demand equation is P(Q) = 600 – 0 Where total supply Q-q1+92. (e) Use your best response equations to mathematically solve for the equilibrium quantities qi 9, Q". equilibrium price...

Problem 4. Three firms operate in an oligopoly market with inverse demand function given by D(Q)a Q, where Q- 1 42 +q3 and q, represents the quantity produced by firm i. Each firm has constant marginal cost of production c and no fixed cost, assume that 0<c<a. The firms compete in the market by choosing quantities in the following way. Firm 1, the industry leader, chooses gi20. Firms 2 and 3 both observe qi. Firm 2 then chooses q2 2...

MomCorp (M) and Planet Express, Inc. (E) are two firms that compete in a Cournot duopoly by simultaneously setting quantities (of package deliveries). Denote MomCorp's quantity by Q and Planet Express's quantity by Qe. The package deliveries they offer are identical, so the price is determined in a combined market according to the inverse demand equation, P = 120-Q, where Q = Qu + Qe. Suppose that MomCorp has constant marginal cost, MCM = 20, while Planet Express has constant...

1. Consider the following asymmetric version of the Cournot duopoly model. Two firms compete by simultaneously choosing the quantities (q, and q2) they produce. Their products are homogeneous, and market demand is given by p- 260-2Q, where Q-q +q2. Firm 1 has a cost advantage; Firm 1 produces at zero cost, while Firm 2 produces at a constant average cost of 40. (The difference in costs is what makes this an asymmetric game.) a. Derive both firms' profit functions, as...
