24.5 we also show Cournot equilibrium point c, where the two reaction curves meet. In other words, Cournot equilibrium is when firms choose sequential, and Stackelberg is when firms choose equilibrium simultaneously. Industrial Organization-Matilde Machado Stackelberg Model 15 3.3. E.g. Comparison with Cournot Model: In Fig. Proposes a model which shows that Stackelberg competition is not necessarily welfareâ enhancing compared with Cournot competition. An important genesis of this model is that one of the Stackelberg leaders produces more output than it would have produced under the Cournot equilibrium. Stackelberg is one firms chosing price or quanity before other. Understanding the Stackelberg Graphically. Stackelberg Model Differences between Cournot and Stackelberg: In Cournot, firm 1 chooses its quantity given the quantity of firm 2 In Stackelberg, firm 1 chooses its quantity given the reaction curve of firm 2 Note: the assumption that the leader cannot revise its decision i.e. Many works studied on complex dynamics of Cournot or Stackelberg games, but few references discussed a dynamic game model combined with the Cournot game phase and Stackelberg game phase. The difference between Cournot and Stackelberg equilibrium is that Cournot equilibrium is chosen in a way that each firm maximizes their profit. Cournot is quantity competition. We compare an m-firm Cournot model with a hierarchical Stackelberg model where m Firms choose outputs sequentially. This recognition allows the sophisticated duopolist to determine the reaction curve of his rival [â¦] 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 entryâdeterrence framework, where postâentry competition is Stackelberg rather than Cournot. Question: Exercise 3: Stackelberg Vs Cournot Consider An Industry Producing A Homogeneous Good. Similarly, the follower in the Stackelberg model produces less output than that in the Cournot model. You decide on quantity and the market (typically and organized exchange) determine the price. In Stackelberg equilibrium, only one firm maximizes their profits. Under the assumption that R&D spillovers only flow from the R&D leader to the R&D follower, a duopoly StackelbergâCournot game with heterogeneous expectations is considered in this paper. While the Cournot model is one of simultaneous quantity setting, the Stackelberg model a quantity leadership model. It is assumed, by von Stackelberg, that one duopolist is sufficiently sophisticated to recognise that his competitor acts on the Cournot assumption. Let Qı Be The Output For Firm 1 And 22 The Output For Firm 2. Market Demand Is Given By P(Q) = 200 â Q Where As Usual Q = 91 +92. We implement both a random matching and a ï¬xed-pairs version for each market. ADVERTISEMENTS: This model was developed by the German economist Heinrich von Stackelberg and is an extension of Cournotâs model. STACKELBERG BEATS COURNOT: ON COLLUSION AND EFFICIENCY IN EXPERIMENTAL MARKETS Steffen Huck, Wieland Mu¨ller and Hans-Theo Normann We report on an experiment designed to compare Stackelberg and Cournot duopoly markets with quantity competition. Abstract. International oil market works this way: OPEC says how much they will produce, and let London and New York exchanges fight over who can pay more for it. While the first mover in a Stackelberg duopoly earns more than a Cournot duopolist, this is not necessarily true for m > 2. Stackelberg equilibrium is attained if and only if firm 1 desires to be a leader and firm 2 a follower. The Stackelberg equilibrium price is lower, so output and total surplus are higher; total profits are lower. We compare an n-firm Cournot model with a Stackelberg model, where n-firms choose outputs sequentially, in a stochastic demand environment with private information.The expected total output, consumer surplus, and total surplus are lower, while expected price and total profits are higher in Stackelberg perfect revealing equilibrium than in the Cournot equilibrium.
