The Impact of Advertising in a duopoly Game

We investigate the impact of advertising in a static differentiated duopoly. First, we consider the Nash equilibrium if firms compete with both prices and advertising. Second, we examine the Nash equilibrium if firms only compete in prices and do not advertise. We characterize the circumstances in which the profit, output, and/or price of each firm is greater (or smaller) with advertising than without advertising.
