PDF | In this paper, a duopoly Stackelberg model of competition on output is formulated. The Stackelberg leadership model is a strategic game in economics in which the leader firm moves first and then the follower firms move sequentially. The Stackelberg leadership model is a sequential model, which means that the dominant firm first sets the price, which is then used by the other firms to determine their optimal production. The principal diﬁerence between the Cournot model and the Stack-elberg In his book „Marktform und Gleichgewicht“, published initially in 1934, Heinrich von Stackelberg presented his groundbreaking leadership model of firm competition. Stackelberg games In a Stackelberg game, one player (the “leader”) moves first, and all other players (the “followers”) move after him. The Stackelberg Model 3. To examine these arguments, we next also allow adjustment costs. Duopoly Model # 1. Generally, in a Stackelberg game, there is a distinctive player called the leader, who optimizes the upper-level problem, and a At the moment, in order to observe the behavior of the solutions of corresponding deterministic model , we set the intensity of the random disturbance to 0, i.e., σ 1 2 = σ 2 2 = 0, then one can easily calculate, (21) b 2 (v 1 + v 2 b + c 2) 2 − 16 (b + c 1) v 1 v 2 = − 0. Although the Cournot model and the Stackelberg model of duopolistic quantity competi tion with homogeneous products and duopolistic price competition with heterogeneous products are part and parcel of every textbook on industrial organization, 1 only few Stackelberg Model Practice Question: Consider the stackelberg model in which …rm 1 sets a quantity q1 Firms produce differentiated or homogeneous products. Barriers to entry. Sherali et al. We model the strategic interactions between the surveillance robot and the intruder as a two-player Stackelberg game with a leader and a follower. Cournot’s model of oligopoly • Single good produced by n ﬁrms • Cost to ﬁrm i of producing qi units: Ci(qi), where Ci is nonnegative and increasing • If ﬁrms’ total output is Q then market price is P(Q), where P is nonincreasing Proﬁt of The Cournot Model 2. In truth, during any adjustment process, the central assumption of the model (i.e., each firm can assume that its competitor’s output remains fixed) will not hold.

It is named after the German economist Heinrich Freiherr von Stackelberg who published Market Structure and Equilibrium (Marktform und Gleichgewicht) in 1934 which described the model. In marketing, Stackelberg differential games have been used to model cooperative advertising programs, store brand and national brand advertising strategies, shelf space allocation, and pricing and advertising decisions. Consumers located on the street with uniform density, ie., there are 0.25 \consumers" living between 0 and 0:25. The purpose of this paper is to take a small step for it.

DeMiguel and Xu: A Stochastic Multiple-Leader Stackelberg Model Operations Research 57(5), pp. The Cournot Model: The oldest determinate solution to the duopoly problem is by the French economist, A.A. Cournot in 1838, who took the case of […] Stackelberg Model Environment Few firms serving many consumers. 3 Industrial Organization- Matilde Machado Stackelberg Model 5 3.3. – The leader commits to an output before all other firms. model such problems is the Stackelberg game [5,68], also called the single-leader-follower game. The second firm (Firm 2) observes this quantity choice and responds to it by choosing its own q2 Iqbal and Toor [7] first gave a quantum perspective on the Stackelberg duopoly game by using Marinatto-Weber quantum scheme presented in … Reina Mercedes s/n, 41012 Stackelberg equilibrium in a dynamic duopoly model. exhibit the Stackelberg independence property.2 This means that not all Stackelberg leadership models have the Stackelberg independence property. Stackelberg Model ( ) ( ) 2 2 12 2 1 2 2 2 21 2 * 1 221 () FOC: 0 2 0 ( ) Cournot's reaction function … ADVERTISEMENTS: The following points highlight the top three models of duopoly. Stackelberg Cournot Model In a Stackelberg Cournot game, one firm (called Firm 1) moves first and chooses a quantity to produce. While the Stackelberg model was originally formulated as a duopoly model, nowadays it is often discussed as a model with one dominant firms and a large number of smaller firms. The game proceeds as follows: the leader commits to a strategy ﬁrst, and then the our model does not allow for the precommitment aspect of output which is part of the appeal of the Cournot model, as formalized in Kreps and Scheinkman. Martin B. Haugh Department of IE and OR, Columbia University, New The model also implies that as N becomes larger, the price cost margins decrease This also seems reasonable intuitively- as there is more competition, –rms have less market power If we send N ! Since the Stackelberg duopoly game is the most typical and simplest dynamic model in classical oligopoly game theory, we focus on its quantum version here. 1220–1235, ©2009 INFORMS 1221 will keep its supply quantity ﬁxed.
