This paper examines the effect of trade barriers on quality levels in a duopoly model for two countries where products are both vertically and horizontally differentiated. In the absence of quality regulation the producer in the large country produces a higher quality than the producer in the...

Recent empirics suggest the relevance of transport cost reductions for world trade growth along with eliminations in protectionist trade barriers. To address the welfare effects of trade cost reductions in a context of `trade and the environment,' we develop a two-stage game model where...

Power market integration is analyzed in a two countries model with nationally regulated firms and costly public funds. If generation costs between the two countries are too similar negative business-stealing outweighs efficiency gains so that following integration welfare decreases in both...

This paper endogenizes the extent of intra-sectoral competition in a multi-sectoral general-equilibrium model of oligopoly and trade. Firms choose capacity followed by prices. If the benefits of capacity investment in a given sector are below a threshold level, the sector exhibits Bertrand...

This paper develops an international trade model where firms in a duopoly may diversify their technologies for strategic reasons. The firms face the same set of technologies given by a trade-off between marginal costs and fixed costs, but depending on trade costs the firms may choose different...

The relationship between market integration and the degree of specialization plays a key role in many areas of economics. In contrast to previous studies, we illustrate that globalization does not necessarily lead to specialization. The analysis is conducted in an extended Dixit-Stiglitz- Ethier...

A two-country model of oligopoly in general equilibrium is used to show how changes in market structure accompany the process of trade and capital market liberalisation. The model predicts that bilateral mergers in which low-cost firms buy out higher-cost foreign rivals are profitable under...

Anti-dumping policies are often justified as legitimate actions by governments in their efforts to protect domestic producers from unfair foreign competition. We investigate the impact of anti-dumping rules on firms' production decisions as to how much and where to produce. Anti-dumping measures...

In a framework of a unionised international Bertrand duopoly with differentiated products, this paper analyses national labour market interdependencies and the consequences of trade liberalisation for union wages. The analysis suggests that national wages are likely to be strategic complements...

This paper presents a new model of oligopoly in general equilibrium and explores its implications for positive and normative aspects of international trade. Assuming “continuum-Pollak” preferences, the model allows for consistent aggregation over a continuum of sectors, in each of which a...
