Saggi, Kamal creator text 2013 monographic Compares equilibrium outcomes of two types of trade liberalization. Looks at bilateralism where countries choose whether to liberalise trade preferentially via a customs union (CU) multilaterally, or not at all; multilateralism in which countries cann form CUs and can only undertake non-discriminatory trade liberalisation. Isolates circumstances where the option to form CUs helps further the cause of multilateral liberalisation as well as where it does not. 6/28/13 SANDRAW Serial
