In this paper we analyze sanctioning policies in international law. We deve
lop a model of international military conflict where the conflicting countr
ies can be a target of international sanctions. These sanctions constitute
an equilibrium outcome of an international political market for sanctions,
where different countries trade political influence. We show that the level
of sanctions in equilibrium is strictly positive but limited, in the sense
that higher sanctions would exacerbate the military conflict, not reduce i
t. We then propose an alternative interpretation to the perceived lack of e
ffectiveness of international sanctions, by showing that the problem might
not be one of undersanctioning but of oversanctioning.
