DESCRIPTION:We study the effect of a merger between two Dutch supermarket 
 chains to assess whether assortment decisions are key strategic instrument
 s for firms responding to local market conditions. We adopt a difference i
 n differences strategy that exploits local variation in the merger’s eff
 ects. We show that the merger did not affect prices but it led the merging
  parties to reposition their assortment to avoid cannibalisation. While th
 e low variety target’s stores reduced the depth of their assortment when
  in direct competition with the acquirer\, the latter increased their asso
 rtment. A simple theoretical model of variety competition explains most of
  our findings.
