1. Suppose Company A is about to play a game with Company B. The following facts are known about the two players. The first Company (Company A) is a row player and uses three different strategies i.e. (Strategy X, Strategy Y and Strategy Z). Whereas the column player (Company B) has two different strategies i.e. (M and N) that can be used accordingly. The payoff matrix is given in the table below.

Question 4: (Answer in 200-400 words in total PLEASE ANSWER THIS HOMEWORK QUESTION The purpose of the Paris agreement was to set a coordination mechanism between countries and limit carbon emissions at a global level. In this period of climate emergency, high carbon emissions and the non respect of Paris agreement by numerous countries, have been criticized in the newspapers and described as dangerous for future generations. From a game theory perspective, respecting or not the Paris agreement can be modeled as a strategic game. Let’s assume that we have two countries who can choose between option 1: not respecting and exiting the Paris agreement (increase their carbon emission); and option 2: respecting the Paris agreement (limit their carbon emission). The following matrix gives the payoffs of each choice, where in each cell, the first number is the payoff of country A and the second number is the payoff of country B. Country B Repect the agreement Exiting the…
6)Game Theory: The Prisoners’ Dilemma: Assume that the Wilson and Spalding athletic equipment companies are in a one-shot game for market share and profits, but that they have the option of choosing only one of two possible price strategies for basketballs: $20 or $80. Obviously if they choose different strategies, the firm with the lower price will win the entire market. The firms face the following payoff matrix (See Chap. 10). Wilson\ \Spalding Wilson $ 20 Price Wilson $ 80 Price Spalding $ 20 Price $ 400, $ 400 $ 1500, $ 0 Spalding $ 80 Price $ 0, $ 1500 $ 1000, $ 1000 What strategy will each firm choose? Why? Which strategy is dominant? Which strategy is preferred by each firm? What will be the outcome of the one-shot game? Where is the Nash equilibrium? Which outcome would be best for the two firms? What will happen if the game is repeated an infinite number of times?
