First, it shapes the nature of forces constraining expansion of Free Trade Agreements (FTAs). The constraining force is a free riding incentive of FTA non-members under relatively high bindings but an exclusion incentive of FTA members under relatively low bindings. Second, multilateral tari§ binding liberalization shapes the role played by PTAs in the attainment of global free trade. Initially, tari§ binding liberalization leads to Custom Union (CU) formation in equilibrium but in a way that undermines the pursuit of global free trade. However, further tari§ binding liberalization leads to FTA formation in equilibrium and in a way that facilitates the attainment of global free trade. Our theoretical analysis also has implications regarding recent empirical discussions over the relative merits of FTAs versus CUs.
