The equilibrium strategy combination in prisoners’ dilemma

Q13 George and Jerry are competitors in a local market. Each is trying to decide if it is
better to advertise on TV, on radio, or not at all. If they both advertise on TV, each will
earn a profit of €3,000. If they both advertise on radio, each will earn a profit of €5,000.
If neither advertises at all, each will earn a profit of €10,000. If one advertises on TV
and the other advertises on radio, then the one advertising on TV will earn €4,000 and
the other will earn €2,000. If one advertises on TV and the other does not advertise,
then the one advertising on TV will earn €8,000 and the other will earn €5,000. If one
advertises on radio and the other does not advertise, then the one advertising on radio
will earn €9,000 and the other will earn €6,000. If both follow their dominant strategy,
then George will:
(a) advertise on TV and earn €3,000;
(b) advertise on radio and earn €5,000;
(c) advertise on TV and earn €8,000;
(d) not advertise and earn €10,000;
Player A and B each announce a color (red, white, blue, or green) simultaneously. The winner is determined by the following rules: red beats white, white beats blue, blue beats green, and green beats red. If both players announce the same color the game is a draw. The payoffs work as follows, if player A wins with red, she wins 5, if player A wins with white or blue, she wins 2, and if player A wins with green, she wins 3. If player B wins with red or white, he wins 4, if player B wins with blue he wins 3, and if player B wins with green he wins 5. The above description leaves out the cases where players announce colors that are not directly comparable. For example, there is no rule for what happens if one player announces white and the other announces green. In these situations, the winner is determined by examining the number of letters in each color that is announced. If both colors have the same number of letters, then the game is a draw. If there are a different number of letters…
A large group of players each guesses a number between 0 and 300. The winner is
the person whose number is closest to three-fifth of the average guess. What is the Nash
equilibrium? Will it be observed? What do you expect for the outcome of this game with next
year's 203 class? (Considering that they have similar sophistication to your class but they
have not covered game theory yet.)

You will need to evaluate the picture of the game below, and answer the question by clicking on a specific area (the hot spot) of the picture. Question: Are there any dominant strategies in this game? If there are, click on the box that corresponds to that dominant strategy (either UP, DOWN, LEFT, or RIGHT). If there aren't any anywhere outside of these boxes. If there are dominant strategies for both players, clicking on only one of them will suffice.

- Two business partners have the opportunity to undertake a new project which will lead to a profit of £1000. First, though, they have to agree on how to split the profit. Consider the following (one-shot) bargaining game: the two business partners can make simultaneous demands. If the sum of their demands is no larger than £1000, then they can proceed with the project, obtain their demands and the rest is given to charity. If the sum of their demands is instead more than £1000, then the project cannot be undertaken, and they both get nothing.• What are the Nash equilibria of this game?• What are the strictly dominated strategies?• What are the weakly dominated strategies?arrow_forwardRefer to the normal-form game of price competition shown below. Introduce A Do Not Introduce B Clone Do Not Clone (5,5) (-10, 50) (500,0) Firm A must decide whether or not to introduce a new product. If firm A introduces a new product, firm B must decide whether or not to clone the product. The subgame perfect Nash equilibrium to this game is: Firm A plays "Do Not Introduce"; firm B plays "Clone" if firm A plays "Introduce." Firm A plays "Do Not Introduce"; firm B plays "Do Not Clone" if firm A plays "Introduce." Firm A plays "Introduce"; firm B plays "Clone" if firm A plays "Introduce." Firm A plays "Introduce"; firm B plays "Do Not Clone" if firm A plays "Introduce."arrow_forwardJohn and Paul are walking in the woods one day when suddenly an angry bear emerges from the underbrush. They each can do one of two things: run away or stand and fight. If one of them runs away and the other fights, then the one who ran will get away unharmed (payoff of 0) while the one who fights will be killed (payoff -200). If they both run, then the bear will chase down one of them and eat them to death but the other one will get away unharmed. Assuming they don't know which one will escape we will call this a payoff of -100 for both. If they BOTH fight, then they will successfully drive off the bear but they may be injured in the process (payoff -20). Construct a payoff matrix for this game and identify the pure strategy Nash equilibrium. (Indicate it with words not with a circle!)arrow_forward

Each player must submit a one-time bid. If the sum of the bids is less than or equal to $100, each player gets the amount of the bid and the game ends. If the sum of the bids is greater than $100, the game ends and the players get nothing. Does this game have a Nash equilibrium?
