It is often alleged that PTAs involving the EC and the US include a significant number of obligations in areas not currently covered by the WTO Agreement, such as investment protection, competition policy, labour standards and environmental protection. The primary purpose of this study is...

The recent theoretical literature on the determinants of trade agreements has stressed the importance of political gains, such as credibility, as a rationale for trade agreements. The empirical literature, however, has lagged behind in the estimation of the economic gains or losses associated...

This Paper uses 67 measures of trade policy and trade liberalization to ask if membership in the World Trade Organization (WTO) and its predecessor the General Agreement on Tariffs and Trade (GATT) is associated with more liberal trade policy. Almost no measures of trade policy are significantly...

This paper fits a gravity model to the trade of 76 market economies. It then applies the model to data on East European economies to estimate what their trading potential might have been, had behaved like market economies in the mid-1980s. At existing levels of national income, the...

At what speed should Mexican agriculture be incorporated into the North American Free Trade Agreement (FTA)? What policies should characterize the transition? We use Mexican agriculture as a case study to analyse the transition problems that arise in most major economic reforms. In particular,...

We show that the standard concertina result for tariff reforms -- i.e. lowering the highest tariff increases welfare -- no longer holds in general if we allow for international capital mobility. The result can break down if the good whose tariff is lowered is not capital intensive. If the...

The paper estimates the effect of NAFTA’s rules of origin (ROO) on Mexican access to the US market treating explicitly the endogenous determination of ROOs. The first equation determines Mexico’s NAFTA (preferential) exports to the US as a function of tariff preference and Estevadeordal’s...

The paper considers the implications of recent changes in the EC relationship with the Central & Eastern European Countries (CEECs) for the EC's traditional links with ACP countries. After reviewing some important aspects of the trade regime implemented by the Lomé Convention, the paper...

For Africa, a regional customs union is unlikely to realise net welfare gains (in the sense of trade creation dominating trade diversion) which cannot be attained through unilateral trade liberalization. Unilateral reform has often failed in Africa, however. A regional customs union tied to...

This paper assesses the effects of reducing tariffs under the Doha Round on market access for developing countries. It shows that for many developing countries, actual preferential access is less generous than it appears because of low product coverage or complex rules of origin. Thus lowering...
