In game theory and economics, a mechanism is called incentive-compatible (IC) [1]: 415 if every participant can achieve their own best outcome by reporting their true preferences. [ 1 ] : 225 [ 2 ] For example, there is incentive compatibility if high-risk clients are better off in identifying themselves as high-risk to insurance firms , who ...
Non-cooperative game theory is in this sense more inclusive than cooperative game theory. It is also more general, as cooperative games can be analysed using the terms of non-cooperative game theory where arbitration is available to enforce an agreement, that agreement falls outside the scope of non-cooperative theory: but it may be possible to ...
For example, B is "throw rock" while A is "throw scissors" in Rock, Paper, Scissors. This notion can be generalized beyond the comparison of two strategies. Strategy B is strictly dominant if strategy B strictly dominates every other possible strategy. Strategy B is weakly dominant if strategy B weakly dominates every other possible strategy.
In game theory, normal form is a description of a game. Unlike extensive form , normal-form representations are not graphical per se , but rather represent the game by way of a matrix . While this approach can be of greater use in identifying strictly dominated strategies and Nash equilibria , some information is lost as compared to extensive ...
Risk dominance and payoff dominance are two related refinements of the Nash equilibrium (NE) solution concept in game theory, defined by John Harsanyi and Reinhard Selten.A Nash equilibrium is considered payoff dominant if it is Pareto superior to all other Nash equilibria in the game. 1 When faced with a choice among equilibria, all players would agree on the payoff dominant equilibrium since ...
A dominant strategy provides a player with the highest possible payoff for any strategy of the other players. In simultaneous games, the best move a player can make is to follow their dominant strategy, if one exists. [11] When analyzing a simultaneous game: Firstly, identify any dominant strategies for all players.
Economics has historically featured multiple schools of economic thought, with different schools having different prominence across countries and over time. [3]Prior to the development and prevalence of classical economics, the dominant school in Europe was mercantilism, which was rather a loose set of related ideas than an institutionalized school.
The dominant players in the field, called the incumbents, are generally invested in maintaining the field in its current form, as changes to the rules of competition risk destabilizing their dominant position. [2] Fields may also feature insurgents who instead aim to alter the field so they can successfully compete with the incumbents. [3]
