stackelberg equilibrium definition

Firm 1 will observe the follower's reaction curve and choose the point which is best for him. What is the altitude of a surface-synchronous orbit around the Moon? SMHM is applied to a real-world case study of EWES in Shanxi, China. Introduction Game theory is the formal, mathematical methodology for analyzing interactions between intelligent players: people, corporations, software agents, or making decisions robots. Did Biden underperform the polls because some voters changed their minds after being polled? 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. @VicAche I see, Thanks - I will revise my answer. In the Stackelberg case any information disadvantage in the sense of Stackelberg fellowership can be eliminated by a more efficient technology. If the follower cannot observe the leader's move, it is no longer irration… These findings could assist stakeholders in resolving conflicts and provide useful information for the integrated management of regional energy, water, and the environment. What would be the most efficient and cost effective way to stop a star's nuclear fusion ('kill it')? Remember both firms have the same production function. In Stackelberg equilibrium: (1) s 1 = t/2, s 2 = t/4. In this study, a stochastic multidivisional hierarchy model (SMHM) is developed for use in planning an energy-water-environment nexus system (EWES). A case study is presented to demonstrate the practicality and efficiency of the model, and different constraint violation risk levels and related results are also obtained. Results provided a range of decision alternatives that corresponded to a tradeoff between system optimality and reliability under uncertainty.

This paper first develops a novel bi-level PSO algorithm to solve general bi-level programs involving nonlinear and large-scale problems. Suppose there is a 50 watt infrared bulb and a 50 watt UV bulb. Topic 4: Duopoly: Cournot-Nash Equilibrium. THE STACKELBERG MODEL 3.1 Definition 3.2 Optimizing in the Stackelberg model 3.1 Definition This is a one period game, where two firms offer an undifferentiated product with known 3.1 Definition 3.2 Optimizing in the Stackelberg model 3.1 Definition This is a one period game, where two firms offer an undifferentiated product with known Do they emit light of the same energy? Then, a BFLP-ESP model was formulated for planning energy system of Beijing, in which the upper-level objective is to minimize CO2 emission and the lower-level objective is to minimize the system cost. Multi-objective programing methods provide comprehensive strategies depending significantly on weights assigned to multiple objectives that are optimized simultaneously (at the same level) and cannot reflect the leader-follower relationship among different decision makers.Bi-level programming (BP) with a two-level structure (i.e. This observer is based on a predefined-time sliding mode algebraic solver and does not require the explicit use of state transformations. There are two firms, which sell homogeneous products, and are subject to the same demand and cost functions. The interactions among DRAs are simulated as a non-cooperative game. One of these companies is known as a leading company , it already has a dominant position and because it has a large number of strategies that determine the one of its followers or its competitors. Total production will be greater and prices lower, but player one will be better off than player … Decision alternatives from BFLP were more beneficial for supporting Beijing to adjust its energy mix and enact its emission-abatement policy. The perfect equilibrium of the game is the Stackelberg equilibrium. This recognition allows the sophisticated duopolist to determine the reaction curve of his rival and incorporate it in his own profit function, which … Therefore, each firm has an incentive to cut prices, but this actually leads to a price war. When trying to fry onions, the edges burn instead of the onions frying up. Since the multilevel programming problem is strongly NP-hard and traditional exact algorithmic approaches lack efficiency, heuristics-based particle swarm optimization (PSO) algorithms have been used to generate an alternative for solving such problems. Show activity on this post. They say "we define a Stackelberg strategy as one which involves taking into account the contemporaneous reaction of one's rival in setting one's own strategy". 3. They consider a three-stage game with two firms. It was recommended for publication in revised form by associate editor I. Rhodes. If products are perfect substitutes this assumes the price will be driven down to marginal cost. The theory is useful for solving problems in many disci- In Cournot model, when there are many competitions, the competitive equilibrium becomes chaotic. Subgame perfection generalizes this notion to general dynamic games: Definition 11.1 A Nash equilibrium is said to be subgame perfect if an only if it is a Nash equilibrium in every subgame of the game. The purpose of this analysis is for the stochastic mean field approximation in Section 3.2 and to show the equivalence between the (adapted open-loop) (ϵ 1, ϵ 2)-Stackelberg equilibrium in Theorem 2 and the (ϵ 1, ϵ 2)-Stackelberg equilibrium with state feedback representation of the followers in Proposition 4 of Section 4.3.
