Kate (K) and Meghan (M) simultaneously choose contributions k € [0, 1] and m € [0, 1], respectively. That is, each of them chooses a contribution which is a real number between zero and one (included). Their payoffs are given by um(k, m) = 2k — m and uk (k, m) = 2m - k, respectively. - (a) Find the set of strategies that survive the iterated elimination of dominated strategies, and find all the Nash equilibria of the game.

1. Consider a sequential continuum game with two players, in which Player 1 first chooses a continuous variable £₁, and then Player 2 selects £2, with payoff functions ₁ and 7₂. Find the best response for P2, as the function î2 = BR₂(x1), for each given #₂: (a) (b) (c) T₂(x1, x₂) ) = (1400 — x1 — x2)x2 − 13x² T₂(x1, x₂) T₂(X1, X2₂) = : 100x2 + 3x1x2 − 14x1 – 30x1x² = 15x2 x² + x² +1
2. Paul and Stella play a game with three strategies each, T, M, and B for Paul, and L, C, and R for Stella. Both move simultaneously. The payoffs are given by the following form: Stella L с R Paul T (8,4) (10, 2) (2,3) M (4,2) (10, 1) (5,7) B (1,4) (10, 3) (9,-4) a. Which strategy is dominated? b. What is the pure-strategy Nash equilibrium? Identify all if there are more than one. c. If Paul moved first, so that Stella observed it, which strategy would Paul choose?

Two neighboring homeowners, i = 1,2, simultaneously choose how many hours to spend maintaining a lawn. The AVERAGE benefit per hour for i is (e.g., it is for homeowner 1) And the (opportunity) cost per hour for each homeowner is 4. (a) Give each homeowner’s (net) payoff as a function of and . (b) Compute the Nash equilibrium.

The US and Canada have overfished North Atlantic cod stocks nearly to the point of extinction. Both countries wish to preserve the cod industry (and hence the cod stocks), so the two countries sign an agreement to limit fish hauls. Each country has two possible strategies: comply with the agreement (limit fishing) or renege on the agreement (overfish). Each country’s payoffs for different strategy combinations are given in the matrix below. The numbers in the cells represent utilities, and the payoff ordering is (US, Canada). QUESTIONS: 1.If this is a one-shot game (i.e., it is played once), do the players have a dominant strategy? If so, what is it? Briefly explain your answer. 2.What is the equilibrium of this game? Is it Pareto-optimal? How do you know?
Two workers are on a production line. They each have two actions: exert effort, E, or shirk, S. Effort costs a worker e > 0 and shirking costs them nothing. If two workers do action E a lot of output is produced and the workers earn £3 each. If only one worker chooses action E less output is produced and they both earn £1. The workers earn nothing if they both shirk. (i) Describe this situation as a strategic form game (assuming the workers do not observe each other's effort choice when making their own decision). (ii) For what values of e does this game have strictly dominant strategies? (iii) Describe the Nash equilibria of this game for e = 0,1, 2, 3. (iv) The workers now are re-arranged into a production line. First worker 1 moves and then worker 2 moves. Worker 2 can now see worker l's effort level before they choose their effort. Draw this extensive form game. (v) Find the subgame perfect equilibria of the production-line game for c = 1/2 and c = 3/2.
Please find herewith a payoff matrix. In each cell you find the payoffs of the players associated with a particular strategy combination: The first entry is the payoff of player 1, the second entry is the payoff of player2. Player 2 t1 t2 t3 Player 1 S1 3, 4 1, 0 5, 3 S2 0, 12 8, 12 4, 20 S3 2, 0 2, 11 1, 0 Suppose both players select their strategies (S1, S2 or S3 for player 1 and t1, t2 or t3 for player 2) simultaneously and that the game is played once. In your explanation to the questions below, please do refer to the figures in the matrix. Suppose player 2 could move before player 1 (i.e. has a first mover advantage). In your explanation to the questions below, please do refer to the figures in the matrix. What strategy would (s)he select? Is it really an ‘advantage’ for player 2 to move first? Or does player 2 benefit from being the second mover (and hence player 1 moving first)? I.e. for this question, do not make a comparison to the outcome of the…
A principal can choose to make the allocation of tasks broad (B) or narrrow (N). At the same time an agent can choose to work put in high effort (H) or low effort (L). The payoffs are 20 to the principal and 30 to the agent is the actions chosen are B and L. For all other combinations of actions the payoffs are 0 to both players. Which of the following statements are true? DA Nash equilibrium of the game is (B, H) A Nash equilibrium is (N, L) There is no Nash equilibrium in pure strategies in this game. A Nash equilibrium is (N, H) A Nash equilibrium is (B, L)
Two workers independently choose how much effort to put in their jobs. If worker 1 chooses e₁ ≥ 0 and worker 2 chooses e2 ≥ 0, their payoffs are given by u₁(e₁,e2,01,02) = 0₁e₁ + ße₁e₂ · - 1/² u₁ (e₁,e₂,0₁,0₂) = 0₂ €₂ + ßе₁e₂. = ²2 where 0 <ß < 1 and 0 ≤ 0; ≤ 1 for i: = 1,2. Assume that 0; is player i's private information: each player knows her own 0 and believes that the other player's 0 is drawn from the uniform distribution over [0, 1]. Find the Bayesian Nash equilibria of this game.
Define a new game as a modified version of the game in Problem 1, which we will call the Matching Two Pennies game: each player choose heads (H) or tails (T) for two pennies. In this game, Player 1 wins if both coins show the same combination of heads and tails, while Player 2 wins if they do not. (a) Write the strategy sets S1 and S2 for this game. (b) Give the payoffs for each player in this Matching Two Pennies game, by defining T;(81, 82) for each player and for each strategy pair, either as a list or in matrix form.
