Symmetric mixed nash equilibrium

WebIntroduction. A substantial body of theory in industrial organization and other fields of economics is built on the idea that there are no equilibria with positive expected profits in a simple Bertrand competition model with homogeneous goods and symmetric firms—in other words, that there are no profitable cartels and that price competition between n > 1 firms … WebNash equilibrium is a pair ˜ f ∗ 1 (x 1),f 2 (x 2) ˚ of distinct functions. In this note we extend the Nash equilibrium solution (1.1) to the case of > 2 symmetric players. Such multi-player N games typically lead to nonlinear problems. Analytic solutions of the kind that we present here are not widespread in the literature.
