Consider two competing firms, JR and OG. Suppose OG produces an estab- lished product and JR can either produce a clone or a differentiated product. If JR produces a clone, OG can either sue JR or not sue it. If JR produces a differentiated product rather than a clone, OG can either buy JR or not buy it. The two firms are in a non-cooperative game whose extensive form is rep- resented in the tree diagram below, where the payoffs on the right represent profits. -1 for OG 1 for JR sue OG don't sue -2 for OG clone 1 for JR JR don't clone 1 for OG -1 for JR buy OG don't buy 2 for OG 0 for JR If the two firms' managers are rational and recognize each other as rational, then (a) JR clones and OG sues (b) JR does not clone and OG buys (c) JR does not clone and OG does not buy (d) JR clones and OG does not sue (e) JR clones and OG sues with probability .5

Economics Alpha and Beta are the only firms selling gyros in the upscale town of Delphi. Each firm must decide on whether to offer a discount to students to compete for customers. If one firm offers a discount but the other does not then the firm that offers the discount will increase its profit. The figure shows the payoff matrix for this game. Alpha Offer Don't offer Alpha eams S60,000 Alpha eams $20,000 What is the Nash equilibrium in this game? Offer Bota earns $60,000 Bota earns $100.000 O A. There is no Nash equilibrium Beta Alpha earns $100.000 Alpha earms $80,000 O B. Beta offers a student discount but Alpha does not Don't OC. Both Alpha and Beta offer a student discount Beta eams $20,000 Beta earns $80,000 offer O D. Alpha offers a student discount but Beta does not

Two firms are competing to establish one of two new wireless communication standards, A or B. A strategy is a choice of standard, and an outcome of this game is a choice of standard by each firm – for example, (A, B) represents the case where Firm 1 decides to develop standard A and Firm 2 develops standard B. Here, the first letter will always correspond to Firm 1’s decision, and the second letter to Firm 2’s decision. Firm 1 has the following preferences over outcomes, in order of highest to lowest preferred: it prefers (A, A) to (B, A) to (A, B) to (B, B). Firm 2 prefers (A, B) to (A, A) to (B, A) to (B, B). Suppose that firms simultaneously decide which standard to develop. What is the pure strategy Nash equilibrium?   Is the answer (B,B)? If not please explian what is the answer?

3. The following is an interpretation of the rivalry between the United States (USA) and the Soviet Ünion (USSR) during the cold war. Each side has the choice of two strategies: Aggressive and Restrained. The payoff table is given as follows: USSR Restrained Aggressiveness Restrained 4,3 1,4 USA Aggressiveness 3,1 2,2 a) Consider this game when the two countries move simultaneously. Find all pure strategy Nash equilibria. b) Next consider three alternative ways in which the game could be played with sequential moves: (i) The USA moves first and the USSR moves second. (i) the USSR moves first and the USA moves second. (i) The USSR moves first, and the USA moves second, but the USSR has a further move after the USA moves. For each case, draw the game tree and find the subgame-perfect Nash equilibrium. c) What are the key strategic issues (commitment, credibility and so on) for the two countries. (Note: Be concise. Your answer should not exceed 300 words].

We can see from the payoff matrix that there are no pure strategy Nash equilibrium in this game because at least one firm would always have an incentive to change its behavior. ​ From​ Nash's​ theorem, we know there must be at least one Nash equilibrium so there must be a mixed strategy Nash equilibrium for this game.   Find the mixed strategy Nash equilibrium by first deleting all dominated strategies in the game   What's the expected payoff to Firm 1 in the equilibrium?

Suppose we have two ice cream sellers, Blue Cool Ice Cream and Red Mango Ice Cream, deciding where to locate along a 1 kilometer long linear beach. Beachgoers are uniformly spread out everywhere along the beach. They do not like walking, and they view the ice cream from the two sellers as homogenous goods. Because of this, they will always buy from the nearest seller. The sellers cannot choose their price, only the location. A strategy for a player in this game is a distance between 0m and 1000m, which represents where the player will locate. For example, a distance of 0m is a strategy. The payoffs are the percentages of the market that each seller captures (depending on their two strategies). For example, if Blue Cool chooses 0m and Red Mango chooses 1000m, their payoffs are 50% and 50%. If the two sellers locate at exactly the same spot, they share the market and get 50% each. Suppose each player can only choose from 5 locations: 0m, 250m, 500m, 750m, 1000m. Is playing 0m is a…
