Assuming constant marginal cost, it is shown that a switch from specific to ad valorem taxation has no effect on the critical discount factor required to sustain collusion. This result is shown to hold for Cournot oligopoly as well as for Bertrand oligopoly when collusion is sustained with...

We show that the static duopoly model in which firms choose between exporting and foreign direct investment is often a prisoners' dilemma game in which a switch from exporting to foreign direct investment reduces profits. By contrast, we show that when the game is repeated there is a range of...

In a Bertrand duopoly model, it is shown that an anti-dumping regulation can be strategically exploited by the domestic firm to reduce the degree of competition in the domestic market. The domestic firm commits not to export to the foreign market which gives the foreign firm a monopoly in its...

The analysis of migration in Findlay (1982) is extended by adding external economies of scale to the Ricardian model as in Ethier (1982). With external economies, the larger country always gains from trade but the smaller country may lose from trade unless the external economies of scale are...

A two-country model of the FDI versus export decisions of firms is analysed. The analysis considers both the Cournot duopoly and the Bertrand duopoly models with differentiated products. It is shown that the static game is often a prisoners' dilemma where both firms are worse off when they both...

This paper analyses how product differentiation affects the volume of trade under duopoly using Shubik-Levitan demand functions rather than the Bowley demand functions used by Bernhofen (2001). The Shubik-Levitan demand functions have the advantage that an increase in product differentiation...
