Bertrand competition with cost uncertainty
We analyze the classical model of Bertrand competition in a homogeneous good market with constant marginal costs and uncertainty regarding rivals' costs. First, we show that there exists a mixed strategy Nash equilibrium under the conventional equal sharing rule. Second, we illustrate the result for the case of piecewise-affine market demand.
