WebIn a rst- or second-price auction, both players bid b 1 = b 2 = 1 so R 1 = R 2 = 1. That is, revenue equivalence still holds. Fact. Revenue equivalence does not always hold without the symmetry of the bidders. Consider the case of two players with v 1 = 2 and v 2 = 1. In a rst-price auction, the Nash equilibrium in pure strategies is to bid b 1 = b WebFirst Draft: August 1996; This Draft: March, 1999 Abstract: This paper derives sufficient conditions for a class of games of incomplete information, such as first-price auctions, to have pure strategy Nash equilibria (PSNE).

WebAug 31, 2015 · Now for a Nash equilibrium, player 1 seeks to maximize his expected value. This is given by the following optimization problem: max b ( 2 − b) ⋅ ( b 2 a) This yields the first order conditions: 1 2 a ⋅ ( 2 − 2 b) = 0, and we obtain that b = 1 is our only solution for player 1. This answer should be reasonably intuitive.
