In very general terms, let the price function for the (duopoly) industry be ; price is simply a function of total (industry) output, so is where the subscript 1 represents the leader and 2 represents the follower. A Stackelberg game has been extensively adopted for solving resource management problems in a network system with a distributed fashion. x��Z[o�~�����+^DI�E���-�'E�>��L�֖r$y���;R�-9NN��KH���p8���E,�xq����7�_�ȅ�E.�w��B/V�m���3z������ZEn�a����C���o5�*ں=�wؚ�c�@3����_�Y|�x�w0�.-S���s�xO�A�x��V�d�E� ��X� Y�h�+]���QlYX���H�ok�� The Stackelberg model can be solved to find the subgame perfect Nash equilibrium or equilibria (SPNE), i.e. /BaseFont/DAWPSF+CMMI8 Ideas such as dominance, backward induction, Nash equilibrium, evolutionary stability, commitment, credibility, asymmetric information, adverse selection, and signaling are discussed and applied to games played in class and to examples drawn from economics, politics, the movies, and elsewhere.

The concept of Stackelberg game was –rst introduced in economics in the 1930™s within the context of static economic competition by Stackelberg (1952). Cournot duopoly, also called Cournot competition, is a model of imperfect competition in which two firms with identical cost functions compete with homogeneous products in a static setting. The book addresses these and other related questions and problems to create the foundation for the Pareto-Nash-Stackelberg Game and Control Theory. It is assumed, by von Stackelberg, that one duopolist is sufficiently sophisticated to recognise that his competitor acts on the Cournot assumption. 495.7 376.2 612.3 619.8 639.2 522.3 467 610.1 544.1 607.2 471.5 576.4 631.6 659.7 In [8], 38 an anti-jamming Bayesian Stackelberg game with incomplete 39 information was proposed, and the optimal strategies based 40 on duality optimization theory were derived. 3.3.

Stackelberg vs Other Models In 1934, Heinrich F. von Stackelberg came up with another model that explains the strategic game through which the firms in an oligopoly decide the level of output in a sequential manner.

Flexible Resource Allocation in Device-to-Device Communications Using Stackelberg Game Theory Abstract: In underlaid device-to-device (D2D) cellular networks, severe radio interference can be typical for cellular and D2D users, which causes each D2D user's quality-of-experience (QoE) to degrade significantly. This is due to von Neumann’s famous minimax theorem (von Neumann 1928). This paper proposes a Stackelberg game theory–based model to assist public agencies in designing payment mechanisms for PPP transportation projects.
