Assumptions of price and output determination under collusive oligopoly: the kinked demand curve model was developed by paul sweezy (1939.
These conclusions supply a rigorous model that justifies sweezy's “kinked demand curve” model that showed why a set of oligopolists might find the monoply.

What is the kinked demand curve model of oligopoly the kinked demand curve model assumes that a business might face a dual demand curve for its product. An oligopoly is a market form wherein a market or industry is dominated by a small number of theory to model the behavior of oligopolies: stackelberg's duopoly in this model, the firms move sequentially (see stackelberg competition.
