In this paper, a conjectured variations equilibrium state (CVE) in a mixed oligopoly model is studied. The agents make conjectures concerning the variations of the clearing price in a dependence upon variations in their production volumes. Existence and uniqueness theorems are established for the conjectured variations equilibrium (called an exterior equilibrium) for any set of feasible conjectures. To introduce the notion of an interior equilibrium, the authors develop a consistency criterion for the conjectures (referred to as influence coefficients). Next, an existence theorem for the interior equilibrium (understood as a CVE with consistent conjectures) is proved. © Springer-Verlag Berlin Heidelberg 2012.
