We consider a two-period framework where a multimarket incumbent firm faces, in one of the markets, a single potential entrant offering a differentiated product. The incumbent has private information about his production cost and may use both pre-entry prices as predatory signals. We find multiple pure strategy perfect bayesian equilibria. Using equilibrium refine- ments, we show that there is always a unique reasonable perfect bayesian equilibrium. Our results show that in some cases this unique equilibrium entails a downward distortion in both low cost incumbent's pre-entry prices. Moreover, we show that this distortion is identical in both markets and increasing with the discount factor, the degree of product substitutability and the efficiency of the entrant. |
