Game theory examines how individuals and groups make strategic decisions when the actions of others influence their outcomes. It helps identify the best strategies by considering all participants' potential choices and reactions to the choices of others. This approach is helpful in gaining insights into many competitive situations where understanding the behavior of others can impact decision-making.

For example, two retail stores are deciding whether to extend their business hours. If only one store extends its hours, it might attract more customers during the additional time, gaining a competitive edge. However, if both stores stay open longer, they might incur higher operational costs without significantly increasing their overall profit. On the other hand, if neither extends its hours, they maintain their current profit levels without incurring extra costs. This scenario represents a classic example of a two-player game where each store's decision impacts its payoff and its competitor, leading to strategic interdependence.

Game theory encourages businesses to think ahead, predict competitors' behavior, and identify equilibrium strategies that maximize potential outcomes. By using this structured approach, firms can make informed choices more likely to result in favorable outcomes. For instance, a company might decide to refrain from reducing prices if it anticipates that its rival will do the same, avoiding a price-cutting cycle that could harm both parties' profitability.

Game theory provides a clearer understanding of competitive dynamics by analyzing potential actions and reactions. This insight enables participants to avoid unfavorable outcomes and identify opportunities for mutually beneficial strategies, resulting in more favorable decision-making.
