Abstract
We investigate mergers in markets where quality dierences between products are central and rms may reposition their product lines by adding or removing products of dierent qualities following a merger. Such mergers are ma-
terially dierent from those studied in the existing literature. Mergers without synergies may exhibit a product-mix eect which raises consumer surplus, but only when the pre-merger industry structure satises certain observable features. Post-merger synergies may lower consumer surplus. The level of, and changes in, the Herndahl-Hirschman Index may give a misleading assessment of how a merger aects consumers. A merger may benet some outsiders but harm others.
