Mergers in financial services and overlending

  • David Peón, Manel Antelo ,


In this paper we build a model of banking competition that considers a managerial-overconfidence setup resulting in two main findings. First, a merger between rational banks may change their behaviour in that, in post-merger conditions, they would follow the overconfident bank when they would not have done so pre-merger, thereby amplifying the credit boom. Second, the results overcome the merger paradox, in the sense that the merger would be profitable for participants and thus intrinsically stable.
