Sammendrag
It is common to apply a SSNIP test with a uniform price increase on all products in the
candidate market. We show that in situations with asymmetries – for example one product
having a limited sale – a uniform SSNIP test can suggest that the relevant market should
include more products even though it could be profitable to increase the price of only one product in the candidate market. Our results are illustrated with some findings from a survey in a local grocery market.
