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 from trade. Though past GATS maritime negotiations involved the maritime nations, we also flag interest...

The paper considers the location of two industries in two countries. Both industries are imperfectly competitive, producing goods for final consumption and use as intermediates. Intermediate usage creates cost and demand linkages between firms, encouraging industrial agglomeration. With high trade barriers each industry operates in both locations in order to supply final consumers. At lower tra...

This paper investigates the implications for international markets of the existence of retailers/wholesalers with market power. Two main results are shown. First, in the presence of buyer power trade liberalization may lead to retail market concentration. Due to this concentration retail prices may be higher and welfare may be lower in free trade than in autarky, thus reversing the standard e¤e...

We develop a model to study the implications of a legal environment on software development and international trade. We show that the degree of contract enforcement a®ects the organizational mode (i.e., in-house or outsourcing) of customized software development. In autarky, a country with weak copyright protection develops customized software only, while a country with strong copyright protect...

This paper reviews some puzzling economic aspects of globalization and argues that they cannot be satisfactorily addressed in perfectly or monopolistically competitive models. Drawing on recent work, a model of oligopoly in general equilibrium is sketched. The model ensures theoretical consistency by assuming that firms are large in their own markets but small in the economy as a whole, and ens...

I consider the implications of recent research for R&D policy in developing countries. Typical new growth models, which assume free entry and no strategic behaviour by R&D producers, are less appropriate for policy guidance than strategic oligopoly models. But the latter have ambiguous implications for targeted R&D subsidies, and caution against the anti-competitive effects of research joint ve...

A two-count ry, twōrm model has been developed to study equilibrium lobbying posit ions in intra-industry trade under cost uncertainty. A ̄rm chooses either a protect ionist posit ion or a free-t rader posit ion. The model predicts that taking the free-t rader (protect ionist) lobbying posit ion is an e± cient (ine± cient) ̄rm's dominant strategy. In addit ion, for any lobbying posit ion taken ...

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 linkages between market access conditions for goods and the structure of the service sector. Competition in...

Le développement de l’économie numérique pose des problèmes inédits par leur ampleur en matière possibles manipulations marché et choix consommateurs. Des stratégies trompeuses déloyales dans le champ du droit la consommation peuvent coexister se renforcer mutuellement, avec infractions concurrence, qu’il s’agisse collusion algorithmique ou d’abus position dominante. Face à difficulté détecter ...
