The Italian Antitrust Review has published a paper on Optimal Pre Merger Notification Thresholds by Paolo Buccirossi, Roberto Cervone and Chiara Riviera.
The paper outlines a theoretical framework to define the optimal notification thresholds so as to minimize the sum of Type I and Type II error costs. Results suggest that, when the notification rule takes into account in a cumulative way both the aggregate turnover of the merging parties and their individual turnover, the optimal values of these turnovers are interdependent. The model is then applied to the Italian case.
