There are several different degrees of incentive-compatibility: [4] The stronger degree is dominant-strategy incentive-compatibility (DSIC). [1]: 415 It means that truth-telling is a weakly-dominant strategy, i.e. you fare best or at least not worse by being truthful, regardless of what the others do.
If a strictly dominant strategy exists for one player in a game, that player will play that strategy in each of the game's Nash equilibria.If both players have a strictly dominant strategy, the game has only one unique Nash equilibrium, referred to as a "dominant strategy equilibrium".
Market dominance is the control of a economic market by a firm. [1] A dominant firm possesses the power to affect competition [2] and influence market price. [3] A firms' dominance is a measure of the power of a brand, product, service, or firm, relative to competitive offerings, whereby a dominant firm can behave independent of their competitors or consumers, [4] and without concern for ...
Dominant Strategy: The strategy where no matter what the other player plays the dominant strategy will always be superior producing and dictating the outcome. [83] Strictly dominated strategy is a strategy where the other strategy chosen always results in a lousier outcome. [84]
The dominant-strategy revelation-principle says that every social-choice function that can be implemented in dominant-strategies can be implemented by a dominant-strategy-incentive-compatible (DSIC) mechanism. This variant was first introduced by Allan Gibbard. [1]
Pareto efficiency is mathematically represented when there is no other strategy profile s' such that u i (s') ≥ u i (s) for every player i and u j (s') > u j (s) for some player j. In this equation s represents the strategy profile, u represents the utility or benefit, and j represents the player. [6]
The booming U.S. stock market will help keep the dollar expensive as global investors pour money into America, a foreign exchange strategist said. But the politics of any trade deals that the ...
A social choice rule is dominant strategy incentive compatible, or strategy-proof, if the associated revelation mechanism has the property that honestly reporting the truth is always a dominant strategy for each agent." [2] However, the payments to agents become large, sacrificing budget neutrality to incentive compatibility.
