We study the dynamics of optimal trade policy in a model with costly inter-sectoral adjustment of labour, where migrants pay less than the marginal social cost of migration. If workers have rational expectations, a future tariff has an announcement effect on the current migration decision. If...

We model the situation where two large countries impose either tariffs or quotas and a third large country remains passive. The introduction of the third country overturns results from two-country models. Stable quota equilibria are capable of reproducing the equilibrium price under tariffs, and...

Partial cooperation in setting trade policy may be worse than no cooperation for countries who form a customs union. The paper investigates three situations where this is likely to occur. First, if the countries forming the union comprise too small a percentage of the non-competitive sector of...

This paper presents promising methodologies for modeling and quantifying nontariff barriers (NTB) to trade in the agricultural and food sectors. We limit the analysis to sanitary, phytosanitary, and technical regulations that can have an impact on trade and to methods that provide some...

We analyze the impact of trade liberalization, removal of production subsidies, and elimination of consumption distortions in world sugar markets using a partial-equilibrium international sugar model calibrated on 2002 market data and current policies. The removal of trade distortions alone...

The double-dividend debate evolves around the possibility (or not) of substituting environmental taxes for more distortionary taxes to reduce both pollution degradation and/or damages (the first dividend) and the excess burden of existing taxes (the second dividend), without eroding tax...

We analyze the potential impact of continuing the existing U.S. sugar program, replacing it with a standard program, and implementing the standard program with multilateral trade liberalization. Under the North American Free Trade Agreement (NAFTA), duty-free sugar imports from Mexico will...

This paper provides a formal analysis of the welfare and trade implications of eco-labeling schemes. A simple model of vertical (quality) differentiation captures major stylized features of the textiles market in which trading takes place between an industrialized North (domestic) and a...

The next three-year World Trade Organization round has been set in motion by recent negotiations in Doha, Qatar. Among the most contentious issues in that meeting, and probably over the course of the next round, is direct and indirect producer support for agricultural exporters in the North and...

We use the global Linkage model to assess the impact of trade and support policies in agriculture on income, trade, and output patterns. We provide order-of-magnitude estimates of the impacts of policy changes rather than point estimates. Two sets of simulations are used to identify key drivers...
