Answer:
firms recognize that because there are only a few firms mutual interdependence is important.
Step-by-step explanation:
Game theory is useful for understanding oligopoly behavior because firms recognize that because there are only a few firms mutual interdependence is important.
An oligopoly can be defined as a market structure comprising of a small number of firms (sellers) offering identical or similar products, wherein none can limit the significant influence of others.
Hence, under the game theory, when firms makes a decision about their business, it is expected that they consider how the other firms would react to such decisions.
