Revisiting the US food retail consolidation wave: regulation, market power and spatial outcomes

This article revisits Neil Wrigley's influential research that explored the corporate restructuring of the US food retail sector, which was characterized by a focus on the spatial implications of merger activity, market concentration and competition regulation. It assesses the importance of this scholarship in a contemporary context, tracking these competitive and regulatory trends from a decade ago to the present. This is of particular interest given the continued concentration of market power and related competitive shake-out; the innovative experimentation with new store formats; anti-trust rulings concerning market definition by the Federal Trade Commission and the challenges faced by European entrants to the market.
