The market structure in which there is interdependence of price-output policies is

An oligopoly is the market structure in which there is interdependence of price-output policies. In an oligopoly, there are a small number of firms that dominate the market and their actions have a significant impact on the market as a whole. These firms often engage in strategic behavior, such as price fixing or collusion, in order to maximize profits. As a result, the firms must be aware of and respond to each other's pricing and output decisions, leading to interdependence of their policies.
