Abstract: 
We modify the UPP test of Farrell and Shapiro (2010) to take into account the possibility that a merger weakens (or eliminates) a vertical supply relationship. After deriving a general effect of the merger, we provide an example of simple estimation strategy when only prices, costs and market shares are available as a snapshot.
