The welfare effects of preferential trading agreements, are most directly linked to changes in trade prices - that is, the terms of trade. The authors use a simple strategic pricing game in segmented markets, to measure the effects of MERCOSUR on the pricing of"non-member"exports to the regional...

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 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 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...

Rich countries'agricultural trade policies are the battleground on which the future of the WTO's troubled Doha Round will be determined. Subject to widespread criticism, they nonetheless appear to be almost immune to serious reform, and one of their most common defenses is that they protect poor...

New Zealand's new Recognized Seasonal Employer program allows workers from the Pacific Islands to come to New Zealand for up to seven months to work in the horticulture and viticulture industries. One of the explicit objectives of the program is to encourage economic development in the Pacific....

The authors discuss options that could be considered in the World Trade Organization (WTO) to provide more favorable treatment-so-called special and differential treatment (SDT)-to small and low-income countries. They argue that there is a need both for differentiation across WTO members and for...

The authors examine regional cooperation among neighboring countries in the area of regional public goods. These public goods include water basins (such as lakes, rivers, and underground water), infrastructure (such as roads, railways, and dams), energy, and the environment. Their analysis...

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...
