This Article analyzes the economic incentives countries face in select
ing an antitrust policy. It demonstrates that, in the presence of inte
rnational trade, antitrust policies chosen by national governments wil
l generally not lead to an outcome that is desirable from an internati
onal perspective. Professor Guzman identifies the reasons why national
policies are different from the optimal global policy and shows how t
he direction of the deviation from the optimal policy depends on trade
patterns and the extent to which national laws are applied extraterri
torially. The author concludes that, although international agreement
is not impossible, the prospects for substantive cooperation on intern
ational antitrust policy are slight. Unlike trade policy, an internati
onal agreement on antitrust policy would benefit some countries at the
expense of others. The Article identifies the potential winners and l
osers from such an agreement and points out that because international
compensatory transfer payments are unlikely, an agreement will be dif
ficult to achieve. Recognizing that agreement is nevertheless desirabl
e to avoid welfare losses associated with a noncooperative approach to
international antitrust policy, Professor Guzman analyzes the fora in
which antitrust agreements are most likely to be negotiated and asses
ses the likelihood of success in each forum. Because concessions in ot
her areas of negotiation may be necessary to compensate countries that
will suffer a loss under a cooperative antitrust policy, the analysis
suggests that negotiations on antitrust policy should be combined wit
h the negotiations of other issues.
