Consistent Conjectural Variations Equilibrium in a Semimixed Oligopoly with Discontinuous Demand

We address a mixed oligopoly model in which a public company maximizes the convex combination of social surplus and its net profit. Based on the concept of conjectural variations, we assume that the producers conjecture the market price in function of their output volume. Production costs are considered quadratic functions and consumer demand is considered a nondifferentiable/discontinuous function. We present results for the existence and uniqueness of the Consistent Conjectural Variations Equilibrium.
