Oligopoly in Homogenous Good Markets: Static Analysis. * At the heart of oligopoly theory is the Bertrand model of price competition

Unique Nash Equilibrium: p1 = p2 = c. Proof: If pi = c, then there is no price at which firm j can earn strictly positive profit so that pj = c is a best response. Thus, p1 = p2 = c is a NE. To show uniqueness, note that if c < pi < pj , then firm j earns zero profit and can do strictly better by unilaterally deviating and charging a price ∈ (c, pi). If c = pi < pj , then firm i earns zero prof...
