In the Fisher market game, since the outcome of the game might be one of several market equilibria, we define a pure Nash equilibrium of the Fisher market game to be a strategy profile where for any deviation of any agent i, agent i's payoff does not increase, for any market equilibrium of the resulting strategy ...
Feb 25, 2010 · There are many NE with very different payoffs, and the Fisher equilibrium payoff is captured at a symmetric NE. We provide a complete polyhedral ...
We show that existence of a conflict-free allocation is a necessary condition for the Nash equilibria (NE) and also sufficient for the symmetric NE in this game ...
The Fisher market game is formed, in which buyers strategize by posing different utility functions and thereby manipulating the Fisher market equilibrium, ...
Nov 21, 2024 · Two important aspects required in this market are: (1) agents need specific amounts of each resource to complete their tasks, and (2) agents ...
This motivates us to study the Nash equilibria of the Fisher market game, where buyers are the players and strategies are the utility tuples that they may pose.
