This paper explores the use of structural models as an alternative to reduced form methods when decomposing observed joint trade and technology driven wage changes into components attributable to each source. Conventional mobile factors Heckscher-Ohlin models typically reveal problems of...

This paper discusses the environmental externalities that are commonly found in the developing world (the environmental regime) along with the policy responses, if any, commonly used to deal with these. Included are the effects of industrial emissions, air and water quality impacts of untreated...

This paper emphasizes the different nature of cross border liberalization in network related services, such as telecoms, compared to liberalization in goods. In the presence of network externalities, it argues that if two disjoint country service networks involving a small and large country are...

This paper discusses efficiency considerations underlying the widespread exemption of food from sales and value added taxes, in contrast to the distributional considerations usually used to justify them, analyzing the implications for tax policy. Although there are increasing returns in both...

We discuss most favoured nation (MFN) treatment in trade agreements, suggesting that its value to individual countries depends critically on the relevant model solution concept used to evaluate it. We analyze both rights to MFN treatment in foreign markets, and the obligation to grant MFN...

We develop a general equilibrium tax model to evaluate the impacts of equal yield base broadening in indirect taxes from high rate narrow based (typically manufactures) taxes to broad based taxes (including services) such as a VAT. We capture differences in choice of mode of supply between...

Existing literature assessing the impacts of transfers on low income households assumes that transfer program participants benefit by the full amount of cash transfers received. We argue that because tax-back arrangements accompany such transfer programmes, and endogenous participantion...

We discuss the role played by discrete labor supply (leisure consumption) choice in" affecting measures of the welfare cost of labor supply tax distortions. We construct comparable" continuous and discrete choice models, each calibrated to have similar aggregate" (uncompensated) labor supply...

Recent literature has explored both physical and policy linkage between trade and environment. Here we explore linkage through leverage in bargaining, whereby developed countries can use trade policy threats to achieve improved developing country environmental management, while developing...

The conventional wisdom is that taxing individuals rather than households is superior from an efficiency point of view under progressive income taxation. This is because it leads to secondary workers, whose labour supply elasticity is high, being taxed at a lower marginal rate than primary...
