LEVY, Philip I. <br/><br/>
Political - economic analysis of free-trade agreements. 

 -  1997 
<br/><br/> Demonstrates that bilateral free-trade agreements can undermine political support for further multilateral trade liberalization.  Points out that if a bilateral trade agreement offers dis-proportionately large gains to key agents in a country, then their reservation utility is raised above the multilateral free-trade level, and a multilateral agreement would be blocked.
