eurorail and swissrail are hypothetical railways that have a duopoly on the route that connects the cities of zurich and munich. both are considering adding an additional daily train to this route. the payoff matrix shows the payoffs for each railway, where eurorail's payoffs for each outcome are listed first in each cell. assume that both companies have complete knowledge of the other's payoff matrix. swissrail add train do not add train eurorail add train $4,000, $1,500 $7,500, $2,000 do not add train $2,000, $4,000 $3,000, $3,000 select the answer that best describes the strategies in this game. eurorail's dominant strategy is to add the train, whereas swissrail does not have a dominant strategy. both companies dominant strategy is to add the train. neither company has a dominant strategy. eurorail's dominant strategy is to not add the train, whereas swissrail's dominant strategy is to add the train. does a nash equilibrium exist in this game? yes, it exists in the upper right quadrant. no, it does not exist. yes, it exists in the upper left quadrant. yes, it exists in the lower left quadrant.
