| 摘要 | We investigate mergers in markets where quality differences between products are central and firms may reposition their product lines by adding or removing products of different qualities following a merger. Such mergers are materially different from those studied in the existing literature. Mergers without synergies may exhibit a product-mix effect which raises consumer surplus, but only when the pre-merger industry structure satisfies certain observable features. Post-merger synergies may lower consumer surplus. The level of, and changes in, the Herfindahl-Hirschman Index may give a misleading assessment of how a merger affects consumers. A merger may benefit some outsiders but harm others. |
