The Heckscher-Ohlin-Samuelson (HOS) model in international trade theory provides a powerful general-equilibrium paradigm for analyzing the impact of changes in trade on factor returns. In the HOS model, factor returns are determined solely by commodity prices, which are determined on large world...

After protracted and difficult negotiations, agreement was recently reached on the dimensions of a South African-EU free trade deal. Because of South Africa's prominence in the sub-region, implementation of this agreement will have an impact not only on South Africa, but on all the SADC...

Changes in real wages are often used to measure welfare changes. There is a problem, however, in interpreting measures of changes in factor returns when analyzing the impact of changes in taxes — such as tariffs and indirect taxes — that operate as wedges in product and factor markets versus...

The debate over the impact of regional trade agreements (RTAs) on world welfare hinges upon (1) whether they are net trade creating or trade diverting and (2) whether they impede multilateral trade liberalization. Theoretical models are ambiguous on these issues. We summarize the insights from...

We surveyed the empirical literature using multi-country computable general equilibrium (CGE) models to analyse potential and actual regional trade agreements (RTAs). The studies indicate that these RTAs improve welfare, that trade creation greatly exceeds trade diversion, and that they are...

We use a general equilibrium model to analyse the employment effects and fiscal cost of a wage subsidy in South Africa. We capture the structural characteristics of the labour market with several labour categories and substitution possibilities, linking the economy-wide results to a...

This paper will review the specification of international trade in CGE models, focusing on how the modelers have drawn on trade theory to build empirical models to analyze issues of: trade liberalization, regional integration, trade-wage links, structural adjustment to macro shocks, choice of...
