1. Two firms compete in a linear city of length 1 unit. Consumers are uniformly located along the city. Consumer i's utility derived from buying firm j's product is given by jj-(-x)2-Pj where j 1,2 indicate the two firms, t is the per unit cost of travelling along the city, is the location of consumer i, x is the location of firm j, and pj is the price of product j. Product one contains some intrinsically superior features and 22,...
QUESTION 6 Consider the Hotelling model of the competition between two firms discussed in class. Select all that apply. 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. D. If Firm 1 is located at position 1/2 (i.e., center of the line) and firm 2 is located somewhere else, then both firms have incentives to deviate and change their position along the line. C....
Consider the Hotelling model of the competition between two firms discussed in class. Select all that apply a. If both firms are localized in position 1/2G.e., center of the line), neither firm has incentives to deviate and move to a different position D. In the Nash Equilibrium in pure strategies firms will localize together anywhere along the line. C. lf Firm 1 is located at position 1/2 (i.e., center of the line) and firm 2 is located somewhere else, then...
2.13. Recall the static Bertrand duopoly model (with homoge- neous products) from Problem 1.7: the firms name prices simul- taneously; demand for firm i's product is a - Pi if Pi < Pi, is 0 if Pi > Pi, and is (a – Pi)/2 if Pi = Pj; marginal costs are c < a. Consider the infinitely repeated game based on this stage game. Show that the firms can use trigger strategies (that switch forever to the stage-game Nash equilibrium...
16:29 Back Problem Set 2 ECON 461 Problem Set 2 Summer 2019 Each qustion will receive equal weight in grading 1. Consider a duopoly in which two firms produce difierent varieties of a differentiated product at constant average and marginal cost 4 per unit. Let the equations of the inverse demand curves be P 700- 7 P-200- +9 (both equations valid wheree the implied prices and quantities are nonnega tive) (a) find Nash equilibrium prices, quantities, and payoffs for a...
5. Consider two firms selling differentiated varieties of a product, e.g., Coke and Pepsi. Each firm j chooses a price pj for its own variety. Since these varieties are close substitutes, the demand that each firm faces depends not only on its own price, but also the price of its competitor. Specifically, the demand for j’s variety is given by Dj (pj , p−j ) = max 0, 60 + p−j − 2pj Suppose that both firms can produce any...
5. (30 points) Consider a Hotelling line city model, where two firms are located at the two extreme points. The length of the city is 1, and the consumers are evenly distributed over the line. Transportation cost per unit is t. The utility of the good for each consumper is 2 and each consumer only consumes one unit of good. Consumer's utility is zero without purchase. Suppose price charged by fir i 1; 2) is pi a). (10 points) Determine...
Q.3 Two firms (i 1, 2) produce differentiated products. The demand function for the product of firm i is given by: qiVi, pj) 4-pi + 2pj firm i and pj the price chosen by its competitor. Firm 1 chooses its price first and firm 2 chooses its price after observing the price of firm 1. The cost function of each firm is G(%) 21. Find the subgame-perfect Nash equilibrium. , where Pi is the price chosen by

Two firms, firm 1 & firm 2, find themselves situated in Hotelling Street, firm 1 at the very beginning of the street and firm 2 at the very end of the street. There are N = 2,000 customers each buying 1 unit of the good from the firm with lower full price (for that customer), i.e., the price charged at the...
