Foreclosure
Foreclosure:The "leverage" concept argued that there is a single source of monopoly prot, and that a bottleneck monopolist can earn the entire monopoly
prot without extending its market power to related segments (vertical
integration cannot increase protability of merging rms).
For example, a bottleneck holder faces a commitment problem similar to that of
a durable-good monopolist (see Coase's durable good analysis): once
it has contracted with a downstream rm for access to its facility, it
is tempted to oer access to other rms as well (even if their competi-
tion to the other rm will reduce monopolist's prots).
Nevertheless,the positioning (downstream or upstream) of the rm is not aleatory
and it has some important consequences on the monopolist's power. A
comparison between exclusive contracts and commitment problem lead
us to two major problems:
(a) upstream bottleneck's prot is smaller, the larger the number of
downstream rms, and
(b) for a given number of downstream rms, the upstream prot is
smaller, the more substitutable the downstream units.
The study of this problems lead the authors to derivate three major
policy implications:
(a) it is important whether the more competitive of two complemen-
tary sectors lies upstream or downstream (prices are lower if the
bottleneck owner lies upstream),
(b) non-discrimination laws may have a perverse eect of restoring the
monopoly power (when an upstream bottleneck practices foreclo-
sure by discrimination among competitors, oering to all com-
petitors the same commercial conditions forces bottleneck to sell
further units at the same high price, that helps it to commit),
