Abstract

We study mergers between firms operating in data-connected markets: the data
generated as a byproduct of the activity on market A can be used by firms operating
on market B. The effects of such a merger depend on whether data trade among
independent firms is possible, and on whether data use benefits consumers or leads
to more surplus extraction. When data increases product B’s quality, the merger
benefits consumers on both markets if data cannot be traded absent the merger, and
harms them otherwise. When data is used to extract consumer surplus on market B
the merger increases consumer surplus on market A and reduces it on market B.
