This paper introduces the Werden-Froeb Index (WFI) to assist in evaluating merger-specific efficiencies in horizontal mergers. The index measures the weighted average reduction in marginal costs required to restore pre-merger equilibrium prices and quantities after the (full or partial) merger...

In Goppelsroeder, Schinkel and Tuinstra (2006) we introduce the Werden-Froeb-index (WFI) to assist in evaluating merger-specific efficiencies in horizontal mergers. The index measures the average reduction in marginal costs required to compensate the anticompetitive effects of the merger and...

In both US and EU merger control, merger-specific efficiencies are recognized as a possible defense for horizontal mergers that raise competition concerns. We introduce the Werden-Froeb-index (WFI) to assist in evaluating these efficiencies. The index measures the weighted average reduction in...

In its landmark ruling in Illinois Brick Co. v. Illinois in 1977, the U.S. Supreme Court restricted standing to sue for recovery of antitrust damages to direct purchasers. However, antitrust damages are typically (in part) passed on to intermediaries lower in the chain of production and...
