24. Summary Continued…  More on Simultaneous move games If all else fails use Nash Equilibrium  Each player selects a strategy that maximizes his payoff given the strategy selected by the other player. Characteristics of Nash Equilibrium  Sometimes there is more than one  Sometimes there is no Nash Equilibrium in pure strategies. There is always a Nash Equilibrium in mixed strategies This slideshow was written by Ken Chapman, but is substantially based on concepts from Thinking Strategically by Avinash K. Dixit and Barry J.

25. Mary and Bob are playing the game described in the table below. Bob picks the columns (either A, B, C, D or E while Mary picks the rows (either 1, or 2). Use concepts from class to pick the likely outcome of this game if their choices are made non-cooperatively and simultaneously.

26. Statement 1: Non-cooperative Nash equilibrium is the economists favorite solution to use in games because you can always find a single predicted outcome to any situation. Statement 2: When we say that a player has a “Dominant” strategy, we mean that no matter what his/her opponent does, that player will always make the same choice. a. Statement 1 is true, but 2 is false b. Statement 2 is true, but 1 is false c.Both are true d.Both are false

27. Alice and Bob are playing the game described in the table below. Bob picks the rows (either A, B, or C, while Alice picks the columns (either D, E, or F). Use concepts from class to pick the likely outcome of this game if their choices are made non-cooperatively and simultaneously. a.Bob will pick B and Alice D b.Bob will pick C, and Alice F. c.Bob will pick C and Alice E. d.Bob will pick A and Alice D. e.None of the above are the solution to this problem

28. Bob and Alice are going to play the non-cooperative sequential game described below. Bob picks first choosing A or B. Alice picks second, picking C or D. After Alice picks, Bob gets to pick once again, choosing either E or F. Payoffs marked with * are for Bob and ** for Alice. What is the likely outcome of this game according to concepts discussed in class?

29. Statement 1: “In a two-player, simultaneous-choice game if strategy A is better for every possible choice of your opponent than strategy B, then we say that you have a dominant strategy.” Statement 2: “If there are no dominant strategies, and no dominated strategies in a game, then there will always be a single Nash equilibrium outcome to help predict what will happen.” a.Statement 1 is true, but 2 is false b.Statement 2 is true, but 1 is false c.Both statements are correct. d.Neither statement is correct

30. Statement 1: “Players in a repeated, simultaneous move game often wish to make a public claim concerning what strategy they will select. One strategy for developing the credibility needed for opponents to believe the claim is to establish a reputation for making that move over time.” Statement 2: “In the situation mentioned in statement 1, another strategy to develop credibility is to publish your strategy in a major newspaper.” a.Statement 1 is true, but 2 is false. b.Statement 2 is true, but 1 is false. c.Both statements are true. d.Both statements are false

31. Statement 1: “In the ‘casino night’ story from Dixit and Nalebuff by the last spin of the roulette wheel in the evening Barry had $700 and Eva had $300. Sine the money amounts were significant only if you had the most at the end of the evening, Barry’s best strategy was to wait for Eva to place her bet, and bet the same amount on the same event.” Statement 2: “In the ‘casino night’ story mentioned above, Eva’s best choice was to put her $300 on a multiple of 3 so that she would receive $900 if she won. Realizing this she should place her bet immediately and hope Barry didn’t know how to respond.” a.Statement 1 is true, but 2 is false. b.Statement 2 is true, but 1 is false.. c.Both statements are correct. d.Both statements are false.

32. Which of the following statements best describe the situation in the simultaneous choice game depicted above? a. Strategy F is a dominated strategy for Edna, while strategy A is a dominated strategy for Bob. b. Strategy E is a dominated strategy for Edna, while strategy A is dominated strategy for Bob. c. There are no dominated strategies in this game. d. Strategy F is a dominated strategy for Edna, while strategy c is a dominated strategy for Bob.
