We are concerned with trade in transport services (not cabotage but rather international shipping, transport, and related logistical services) and the importance of competition and market structure in the sector. We examine implications of liberalization for profits, trade, and national gains...

We examine interaction between goods trade and market power in domestic trade and distribution sectors. Theory suggests a linkage between service-sector competition and goods trade, one supported by econometrics involving imports of 22 OECD countries vis-à-vis 69 exporters. This points to...

In this Paper we examine the interaction between the different modes of market access commitments in services (cross-border and establishment) market structure, and regulation. In this context, we focus on the impact of improved domestic market access for a foreign service provider on a domestic...

Recent theoretical work predicts that an important margin of adjustment to deregulation or trade reforms is the reallocation of output within firms through changes in their product mix. Empirical work has accordingly shifted its focus towards multi-product firms and their product mix decisions....

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...

A firm's productivity depends on how production is organized given the level of demand for its product. To capture this mechanism, we develop a theory of an economy where firms with heterogeneous demands use labor and knowledge to produce. Entrepreneurs decide the number of layers of management...

This paper calls into question the currently most influential model of international trade. An empirical finding by Trefler (2004, AER) and others that industrial productivity increases more strongly in liberalized industries than in non-liberalized industries has been widely accepted as...

We assess some likely consequences of commercial policy in an intertemporal CGE model of an imperfectly competitive, small open economy. Specifically, we combine an overlapping generations model of aggregate savings with capital accumulation by forward-looking investors and production under...

This paper presents a trade model with firm-level productivity differences and R&D-driven growth. Trade liberalization causes the least productive firms to exit but also slows the development of new products. The overall effect on productivity growth depends on the size of intertemporal...
