Question

Players $A$ and $B$ are engaged in a coin-matching game. Each shows a coin as either heads or tails. If the coins match, $B$ pays A $\$ 1 .$ If they differ, $A$ pays $B \$ 1$ a. Write down the payoff matrix for this game, and show that it does not contain a Nash equilibrium. b. How might the players choose their strategies in this case?

Step 1

The payoff matrix for this game would look like this: | | Heads (B) | Tails (B) | |-------|-----------|-----------| | Heads (A) | 1, -1 | -1, 1 | | Tails (A) | -1, 1 | 1, -1 | In this matrix, the first number in each cell represents the payoff Show more…
