Both Firm W and Firm H have a dominant strategy to advertise.
Step-by-step explanation:
Dominant strategies, never despite what other competitors do, are treated similarly than others. In game theory, two forms of strategic supremacy exist:
-a strategy that is purely dominant is a strategy which provides the player with often better advantage, regardless of what the another player's strategy is ;
- a strategy that is weakly dominant, which gives all these other player's strategies the very same value, and which makes certain strategies more stringent.
Especially if one game is only weakly dominant (this means that it also does at least the same thing as any other strategy, but it just can in certain situations match other strategies, not beat them), and the same wages would apply to the player may be applied to more than one dominant strategy per player.
