The strategy literature has found it difficult to differentiate between collusive and efficiencybased synergies in horizontal merger activity. We propose a theoretically-backed methodological approach to classify mergers that yields more information on merger types and merger effects, and that...

This paper empirically evaluates the price effects of the merger of two major book retail chains in the UK: Waterstone's and Ottakar's.
