Consider the following one-shot Bertrand game. Two identical firms produce an identical
product at zero cost. The aggregate market demand curve is given by 6 − p , where p
is the price facing the consumers. The two firms simultaneously choose prices once.
Suppose further that the firm that charges the lower price gets the entire market and if
both charge the same price they share the market equally. Assume that prices can only
be quoted in integer units (only prices of 0, 1, 2, ... are allowed).
(a) Find the monopoly price. [5 marks]
(b) Find all the pure strategy Nash equilibria. [10 marks]
(c) Find that the set of prices that survive iterative elimination of weakly dominated
strategies. [20 marks]

Solutions

Expert Solution

b) Each firm has 3 strategies (0,1,2)

That is either to choose price 0 or 1 or 2.

Two identical firms compete in a Bertrand duopoly. The firms produce identical products at the same constant marginal cost of MC = $10. There are 2000 identical consumers, each with the same reservation price of $30 for a single unit of the product (and $0 for any additional units). Under all of the standard assumptions made for the Bertrand model, the equilibrium prices would be Group of answer choices $10 for both firms $30 for both firms $50 for both...

Suppose there are two firms that produce an identical product. The demand curve for their product is represented by P=60-2Q, where Q is the total quantity produced by the two firms. The marginal cost of production is zero and there are no fixed costs. A. Refer to Scenario: Oligopoly. Suppose both firms choose their individual quantities q1 (firm 1) and q2 (firm 2) simultaneously and independently (so Q = q1 + q2). What is the unique Nash equilibrium price? B....

Q2. Consider a Bertrand game with differentiated products in which two firms simul- taneously choose prices. The marginal cost for each firm is zero and there are no fixed costs. The demand functions for each firm are: Q1 = 80 − 2P1 + 2P2, Q2 = 80 − 2P2 + 2P1. where P1 is the price set by firm 1, P2 is the price set by firm 2, Q1 is the quantity demanded of firm 1’s product and Q2 is...

Problem 1: Consider the following Bertrand duopoly: two firms (A and B) are operating in a market where they produce identical products and compete on price. Assume that the market demand can be written as ? = 50 − ?. Assume that neither firm is capacity constrained so that either firm can satisfy the market demand at any price. Suppose further that the profit function for each firm can be written as ? = ?? − ?? = (? −...
