Abstract: | The authors use a two-period model to analyze the short run and long run profitability and welfare consequences of horizontal mergers, where the equilibrium responses to a merger can differ over time. Although firms can anticipate the merger, they can only adjust their capacity in the long run. The authors find a greater range of profitable mergers than in static models. For a merger to raise welfare, it is sufficient that the short run welfare effects are positive and necessary that the long run effects are positive. |
