6. Case study: supermarkets merger
Conclusion based on aggregate

6/9 merging party stores would not be
able to raise prices following the merger
How do responses to questions
differ for M/F respondents?
For 8/9 stores, more M than F
divert to a merging party store.
Implications for competition policy?
Can the supplier negatively impact M through price
differentiation (e.g. personal discounts to F), or product
differentiation (e.g. product range)?
