Business decisions rarely happen in a vacuum. A change in a competitor’s pricing, a supplier’s decision to renegotiate, or a new entrant’s expansion plans can quickly alter the choices a company faces. What looks like a straightforward decision can therefore have very different consequences depending on how others respond. Game theory in business helps managers look beyond their immediate choices and consider the likely reactions, incentives and decisions of the other players involved.
From “What should we do?” to “How will others respond?”
What is game theory? It looks at what happens when one business decision affects the choices available to others. In a business setting, a move that seems beneficial on its own can lead to an unexpected response. Take a price cut: it may help a company win customers, but competitors could lower their prices too, setting off a price war. The better approach is to weigh the immediate gain against how rivals are likely to react.
Game theory strategy is about shaping the game
This distinction matters because managers can sometimes influence the choices available to other players. A company investing in additional production capacity, for example, may be doing more than preparing for future demand. It may also be signalling that it is prepared to compete aggressively if a rival enters the market.
Such game theory strategy is often about commitment. By making a decision difficult or costly to reverse, a company can change competitors’ expectations. Research in strategic management has examined commitment decisions involving pricing, capacity, innovation and market share, demonstrating how a firm’s choices can alter subsequent competitive behaviour.
This is one reason game theory is particularly relevant to senior managers. The objective is not merely to predict a competitor’s next move. It is to understand which actions could change that competitor’s incentives in the first place.
What game theory examples in business reveal
Some of the most practical game theory examples in business come from situations where one company’s decision affects what others choose to do. Take advertising: two competing firms may both prefer to keep spending under control, but each may feel compelled to spend more if it expects the other to increase its advertising. If both take that approach, they can end up spending significantly more without gaining much in return. Nash equilibrium helps explain why these situations can continue, even when both companies might prefer a different outcome. The same idea applies to pricing, negotiations and relationships with suppliers, customers and other business partners.
The managerial value: anticipate, influence and adapt
Game theory is not about predicting exactly what a competitor will do next. Business decisions rarely play out that neatly. Managers often have to work with limited information, changing circumstances and responses they did not anticipate. The real value of game theory is that it encourages them to think a few steps ahead: Who else is involved? What are they trying to achieve? How might they react to our decision?
For business leaders, looking at decisions this way can bring greater clarity to situations where competitors and stakeholders may respond in unexpected ways. The Executive Programme in Strategy and Leadership at ISB encourages professionals to build this wider strategic view. At its core, game theory in business helps leaders anticipate possible responses and make decisions with a clearer sense of what may follow.
