Oligopoly refers to a market structure in which a few large firms dominate the market. In such a market, pricing strategies play a critical role in determining the competitiveness of the firms. Here are some pricing strategies that oligopolistic firms can adopt:

1. Price leadership: In an oligopoly, one firm may take the lead in setting prices, and other firms follow suit. This strategy is known as price leadership. The leading firm may set prices high, and other firms follow suit, or it may set prices low, forcing other firms to match its prices.

2. Collusion: In an oligopoly, firms may collude to set prices. Collusion occurs when firms agree to cooperate rather than compete with each other. By colluding, firms can set higher prices and increase their profits.

3. Price discrimination: Oligopolistic firms may engage in price discrimination by charging different prices to different customers. This strategy is used to maximize profits by charging higher prices to customers who are willing to pay more and lower prices to customers who are not.

4. Non-price competition: Oligopolistic firms may engage in non-price competition by offering better quality products, better customer service, or other incentives. This strategy is used to differentiate the firm's products from those of its competitors and to gain a competitive advantage.

5. Predatory pricing: Oligopolistic firms may engage in predatory pricing by setting prices below the cost of production to drive competitors out of the market. Once competitors are eliminated, the firm can raise prices and increase its profits.

Overall, oligopolistic firms have a range of pricing strategies available to them, and the strategy they choose will depend on the market conditions, the behavior of their competitors, and their own objectives.
