Cournot Vs Stackelberg Equilibria with a Public Enterprise and International Competition Richard C. Cornes∗ Mehrdad Sepahvand† Abstract This paper examines the validity of alternative assumptions about public enterprise strategies in the presence of both domestic and in-ternational competition. The difference between Cournot and Stackelberg equilibrium is that Cournot equilibrium is chosen in a way that each firm maximizes their profit. International Journal of Industrial Organization, Vol. Industrial Organization-Matilde Machado Stackelberg Model 15 3.3. Stackelberg markets yield, regardless of the … Although Cournot’s model was based on some unrealistic assumptions, his method of analysis has been useful for subsequent theoretical development in the areas of duopoly and oligopoly. Shows that, although in a simple duopoly model prices in a Stackelberg equilibrium are lower than in a Cournot equilibrium, this is not necessarily true in an entry‐deterrence framework, where post‐entry competition is Stackelberg rather than Cournot.

Under the assumption that R&D spillovers only flow from the R&D leader to the R&D follower, a duopoly Stackelberg–Cournot game with heterogeneous expectations is considered in this paper. The Stackelberg leadership model results in a higher market quantity and lower price for the good as compared to the Cournot model. This holds true in the short-run, at the steady-state, and in terms of discounted welfare. The first one has made a great contribution towards explaining oligopoly as well as non-cooperative game theory. The Stackelberg model is about strategic competition. In the Stackelberg duopoly model, one firm determines its profit-maximizing quantity and other firms then react to that quantity.

Abstract. The issue of equilibrium selection in a duopoly game between a profit maximizing and a labour managed firm is addressed under either price or quantity competition with product differentiation. Let Qı Be The Output For Firm 1 And 22 The Output For Firm 2. B) In Stackelberg, both firms make output decisions simultaneously, and in Cournot, one firm sets its output level first. In Stackelberg equilibrium, only one firm maximizes their profits. A) In Cournot, both firms make output decisions simultaneously, and in Stackelberg, one firm sets its output level first. While the first mover in a Stackelberg duopoly earns more than a Cournot duopolist, this is not necessarily true for m > 2. We proceed with a comparison between the feedback Stackelberg and the feedback Cournot equilibria, and find a number of interesting results in contrast with “static” oligopoly theory. In other words, Cournot equilibrium is when firms choose sequential, and Stackelberg is when firms choose equilibrium simultaneously. Duopole asymétrique de Stackelberg La concurrence de Stackelberg est un modèle de duopole. Explain Cournot, Bertrand and Stackelberg models of oligopoly assuming that the firms have identical costs.

As in the standard Cournot duopoly, lower isoprofit curves for firm 1 (or isoprofit curves more on the left for firm 2) correspond to higher profit levels.

Cournot Competition: Is a model (Oligopoly the model was built on Duopoly) where a firm competes in the Oligopoly market on quantity, maximizing profit given what it believes the other firm(s) will produce. The reason there are more than one model of oligopoly is that the interaction between firms is very complex. We also show that the first n-1 firms' expected profits form a decreasing sequence from the first to the (n-1)st in the Stackelberg game. We reconsider Stackelberg's classical critique of the Cournot duopoly, in the framework of endogenous timing for two-player games. Proposes a model which shows that Stackelberg competition is not necessarily welfare‐ enhancing compared with Cournot competition. B) In Stackelberg, both firms make output decisions simultaneously, and in Cournot, one firm sets its output level first. 3.2. We propose an infinite-horizon differential oligopoly game where, at each point in time, m Stackelberg leaders and n−m Stackelberg followers exploit a common-pool renewable resource and sell their harvest in the marketplace at a price that depends on total harvest.
