3. Assume that there are two players (Player 1 and Player 2) and they have strategies as \( s_{1} \) and \( s_{2} \). They have the following utility functions: \[ \begin{array}{c} U_{1}\left(s_{1}, s_{2}\right)=40 s_{1}-s_{1}^{2}+4 s_{1} s_{2} \\ U_{2}\left(s_{1}, s_{2}\right)=100 s_{2}-50 s_{1}-s_{2}^{2}-s_{1} s_{2} \end{array} \] a. Find the Nash equilibrium if it is a static simultaneous move game. b. Find the equilibrium if it is a dynamic sequentially move game. (The game starts with Player 1 and goes on with Player 2)

Player 1 has strategies A, B, and C. Player 2 has strategies D, E, and F. D E F A (2,2) (1,3) (0,1) B (3,1) (2,1) (1,1) C (1,0) (0,0) (3,0) (a) (2pts) Does Player 1 have any strictly dominated strategy? If yes, find them and state what strategy strictly dominates them. (b) (3pts) Does Player 2 have any weakly dominated strategy? If yes, find them and state what strategy weakly dominates them. (c) (2pts) Is there any weakly dominant strategy for player 1? If yes, find it. (d) (2pts) Is there any weakly dominant strategy for player 2? If yes, find it. (e) (3pts) Find all pure-strategy Nash equilibria. Write each equilibrium as a strategy profile, for example (A, D), rather than payoff pair (2,2). (f) (3pts) Determine if each Nash equilibrium is Pareto efficient.

In a two-player, one-shot simultaneous-move game, each player can choose strategy A or strategy B. If both players choose strategy A, each earns a payoff of $400. If both players choose strategy B, each earns a payoff of $200. If player 1 chooses strategy A and player 2 chooses strategy B, then player 1 earns $100 and player 2 earns $600. If player 1 chooses strategy B and player 2 chooses strategy A, then player 1 earns $600 and player 2 earns $100. Required: a. Write the above game in normal form. b. Find each player's dominant strategy, if it exists. c. Find the Nash equilibrium (or equilibria) of this game. d. Rank strategy pairs by aggregate payoff (highest to lowest). e. Can the outcome with the highest aggregate payoff be sustained in equilibrium? Why or why not?
