Despite the burgeoning empirical literature providing evidence of a strong and robust positive correlation between trade and migration, doubts persist as to unobserved factors which may be driving this relationship. This paper re-examines the trade-migration nexus using a panel spanning several...

The authors explore the argument that trade between the Mercosur countries should be stimulated by preferential policies because of their geographic proximity. That is, that the Mercosur countries are candidates for natural integration. They find that, on average, transportation margins on trade...

The author focuses on whether regionalism sets up forces that encourage or discourage evolution toward globally free trade. Although models can be built suggesting either conclusion, these models are still so abstract that they should be viewed as parables rather than sources of testable...

Regional integration agreements (RIAs) are examples of second best and have an ambiguous impact on welfare, contend the authors. They build a model in which RIAs unambiguously raise welfare by correcting for externalities. It assumes that trade between neighboring countries increases trust...

The authors explore the effects on the terms of trade of regional economic integration. They show why it is an appropriate measure of the welfare effects of such integration, comparing it with the many ex post studies that base their conclusions on changes in the import shares of member and...

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...

Openness and liberal trade policies are associated with higher exports and economic growth. Sub-Saharan African countries are mostly still relatively closed, and one of their top priorities should be to open up. With some important, identifiable, exceptions African exports are not...

While barriers to trade in most goods and some services including capital flows have been reduced considerably over the past two decades, many remain. Such policies harm most the economies imposing them, but the worst of the merchandise barriers (in agriculture and textiles) are particularly...

This paper surveys the broad patterns of world trade in manufactures since about 1960. While the bulk of manufactured exports came initially from relatively few large industrial countries, developing countries have encroached seriously upon their markets in recent years. The newly industrialized...

This paper traces the links from trade shocks to poverty in developing countries. It considers the determinants of household and individual welfare (including potential differences between household members) and then identifies six trade-to-poverty links: the extent to which prices change and...
