In a game theory scenario, if Firm A has a dominant strategy to always set a high price, it implies that Firm B will also choose to set a high price in response, regardless of its own dominant strategy.

In game theory, a dominant strategy is a choice that is best for a player, no matter what the other players decide to do. If Firm A always chooses to set a high price because it maximizes its profits, this means it's the best option for them regardless of Firm B's actions. Firm B, seeing that Firm A has a high price, may also choose to set a high price to avoid losing customers or profits, even if Firm B might have a different dominant strategy. For example, if both firms are selling similar products, Firm B might think that matching Firm A’s high price will help them stay competitive in the market. This situation shows how one firm’s decision can influence another's, leading to a situation where both firms end up setting high prices.
