Why is Price Stickiness likely to happen in an oligopoly market structure?

Price stickiness in an oligopoly market structure occurs because firms are interdependent and tend to avoid price wars that could erode profits. When one firm changes its price, others often follow suit to maintain market share, leading to a tacit understanding that prices should remain stable. Additionally, firms may rely on non-price competition, such as advertising and product differentiation, to attract customers rather than altering prices. This behavior results in a reluctance to change prices frequently, contributing to price rigidity in the market.
