Levinsohn, James A., and Henrik Horn. 2001. "Merger Policies and Trade Liberalization." Economic Journal, 111(470): 244-276.
This paper is about the interactions between trade policy and a narrow but important aspect of competition policy, namely merger policy. We focus on links between merger policies and trade liberalisation. We put special emphasis on the topical issue of the role that international agreements such as the GATT play when merger policies are nationally chosen. Of particular concern is the possibility that liberalisation of international trade will induce countries to use competition policies to promote national interests at the expense of others.
