A town has two repair shops, Blue and Red. Each shop must decide whether it will remain open on Sunday or be closed on that day. The payoffs, which are in dollars, are provided in the normal form below. This is a static, or one-shot, game.

Assuming the shops make their decisions simultaneously:
(A) Which shop is the most profitable in the Nash equilibrium?
(B) Does the shop you identified in part (A) have a dominant strategy? If so, what is it?
(C) What should this shop do? Explain your answer.
(D) Is this an example of a prisoners’ dilemma.
A) Blue is the most profitable in the Nash equilibrium. This is perhaps because it's payoff are greater in every condition when compared with its rival. This can be seen from the fact that in every cell profit are at least as much as the profit earned by Red
B) yes it has a dominant strategy and it to remain closed on Sunday. For every strategy selected by the rival if Blue remains closed on Sunday, it has a higher profit of 10000 and 12000 compared to its profit of 8000 and 7000 when it opens.
C) because it has a dominant strategy of closed on Sunday, Blue should remain closed on Sunday.
D) No. This is not an example of a prisoners’ dilemma because here the selected outcome (closed, closed) has a overall higher profit at 18000 (12000 + 6000). This is a Pareto efficient outcome, unlike prisoners’ dilemma game where the selected outcome has lower profits for both.

Consider a small town that is served by two grocery stores, White and Gray. Each store must decide whether it will remain open on Sunday or whether it will close on that day. Monthly payoffs for each strategy pair are as shown in the table below. Which firm is the most profitable in this market? Does Gray have a dominant strategy? Is there a dominant equilibrium for both firms? Is the dominant equilibrium profit-maximizing? Is this an example of the...
There are two firms, Cope and Peski, in an oligopolistic industry. Each firm must decide whether or not to advertise during the Super Bowl this year. The diagram below represents the matrix of expected profit payoffs for each firm depending on which of the four possible outcomes becomes reality. The first number in each cell represents the expected profit for Peski given the relevant combination of strategies for each firm. The second number in each cell represents the expected profit...
Two companies, Chevron and Shell, are the only two gas stations operating in a small town. Each company must simultaneously display their prices, choosing between a high price and low price. The profits each firm can potentially earn are displayed in the payoff matrix displayed below: a. What is Chevron’s most likely decision (what is their dominant strategy)? b. What is Shell’s most likely decision (what is their dominant strategy)? c. What is the most expected outcome (what is the...
