It has been suggested that mergers, by increasing profitability, will also result in higher investments. To deal with this claim, we first study a general model with simultaneous cost-reducing investments and price choices. Absent scope economies, the merger is anti-competitive: it lowers both total output and investment. With sequential choices, we provide a sufficient condition in a general model for the merger to be anti-competitive. The results are confirmed in a standard Shubik-Levitan parametric model. Only if the merger entails sufficient scope economies, will it be pro-competitive. We also show that a Network Sharing Agreement (by which parties set their investment cooperatively) is preferable to a merger. Finally, we identify a class of models where the same qualitative results extend to quality-enhancing investments.
