Abstract: This paper analyzes the impact of a merger in the French retail sector on food prices, using a consumer panel data. We perform a di fference-in-diff erences analysis by comparing price changes in stores for which the local market structure is aff ected by the merger to unaff ected stores. In addition, we empirically investigate economic forces behind the observed price changes. On average, we fi nd that the merger signifi cantly raised competitors' prices contemporaneously with merging firms' price increases. Further, we show that competitor prices increase more in local markets that experience larger structural changes in concentration and chain diff erentiation.
