The authors apply a gravity model to data on annual non-fuel imports for 58 countries for the years 1980-96, to quantify the effects on trade of recently created or revamped preferential trade agreements (PTAs). They modify the usual gravity equation to identify the separate effects of PTAs on...

The paper applies a gravity model to 1980-1996 annual non-fuel imports data for 58 countries to quantify the effects of recently created or revamped PTAs on trade. We modify the usual gravity equation to identify separate effects of PTAs on intra-bloc trade, members' total imports and their...

The theoretical literature follows two different approaches to explain the endogenous formation of a Customs Union (CU). The first one explains CU formation through the willingness of integrating partners to exploit terms-of-trade effects. Indeed, as the union forms, the 'domestic market' gets...

The results of a modified gravity model suggest that the new wave of regionalism has not boosted intra-bloc trading significantly. Trade liberalization in Latin America did have a positive impact on the imports of bloc members, although MERCOSUR`s exports did poorly over the mid-1990s.Soloaga...

Most researchers focus on the political economy (interest group pressures) approach to analyzing why customs unions are formed, but terms-of-trade effects were also important in formation of the Common Market of the Southern Cone (Mercosur). Terms-of-trade externalities among Mercosur's members...
