Price leadership occurs in oligopolistic markets where one dominant firm sets the price that competitors feel compelled to match. This avoids uncertainty for all firms. For price leadership to work, the market must have few firms, restricted entry, homogeneous products, inelastic demand, similar cost structures, and one technologically superior leader. There are different types of price leadership depending on whether the leader has the lowest costs, the largest market share, or best ability to forecast conditions. In all cases, the leader initiates well-publicized price changes that smaller rivals follow to leverage the leader's expertise and stability and avoid price wars. However, anti-monopoly laws restrict abusive behavior from price leadership.
