Horizontal market concentration: Theoretical insights from spatial models

This paper aims to further the study of horizontal mergers by reviewing the theory on spatial models that may be useful for their analysis. We examine the incentives conveyed by locations for undertaking merger and merger-related strategies, as well as the impact of the latter on strategic location choices. This literature review therefore focuses on the two-way relationship between horizontal market concentration and firm location.

► The impact of location for horizontal mergers.
► The impact of horizontal mergers for location choices.
