This paper analyzes how uncertainty influences the formation and design of regional trade agreements (TAs). Two sources of uncertainty — in demand and costs — are considered. Using a multi-stage game we show that, as long as some decisions are made after uncertainty is resolved,...

Trade Theory, Analytical Models and Development, comprises 11 essays offering new contributions on the following topics: trade and wages; factor endowments, factor mobility and political economy of trade; optimality of tariffs; measurement of welfare; customs union theory; endogenous mergers and...

We raise the possibility that at least some of the free trade areas observed in practice are customs unions in disguise. We distinguish between generalized and standard customs unions. While members of the former can choose different external tariff rates, members of the latter levy a common...

This paper analyzes how uncertainty and the timing of its resolution influence the formation and design of regional trade agreements. Two sources of uncertainty ? in demand and costs ? are considered. We compare the case in which uncertainty is resolved "early" (before tariffs are chosen), with...

This paper provides an in-depth examination of the trade effects of three regional trade agreements (RTAs) – the ASEAN Free Trade Agreement (AFTA), the Common Market for Eastern and Southern Africa (COMESA) and the Southern Cone Common Market (MERCOSUR) -- in the agricultural sector. Results...

This paper evaluates the different approaches to quantifying the trade impact of standards in the agri-food sector. The approaches discussed fall into two broad categories: ex post empirical estimation and ex ante simulation. Recent developments on the impact of standards on market segmentation...

This paper investigates how customs union members select the common external tariff (CET) to levy on imports from nonmembers. A perfectly competitive, pure exchange, general-equilibrium model of world trade is simulated. Contrary to most previous work, countries have the freedom to share...
