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...

The outcome of a trade war (with import tariffs and export subsidies) between two countries is analysed in a Cournot duopoly and in a Bertrand duopoly with differentiated products. The model allows for asymmetries between the countries in terms of competitiveness. When the two countries are...

Welfare with the maximum-revenue tariff is compared to free-trade welfare under perfect competition in the case of a large country able to affect its terms of trade; under Cournot duopoly with differentiated products; and under Bertrand duopoly with differentiated products. Under perfect...

This paper analyses the welfare effects of ad valorem and specific trade policy instruments (import tariffs and production subsidies) under asymmetric Cournot oligopoly and then compares the efficiency of ad valorem with specific instruments. It is shown that these trade policy instruments have...

For an oligopolistic industry, the effects of mergers on the domestic country"s optimal trade policy are analyzed. If the domestic country pursues an optimal trade policy then it will always lose as a result of a foreign merger. The optimal domestic response to a foreign merger is to decrease...

In the <link rid="b7">Eaton and Grossman (1986</link>) Bertrand duopoly model of strategic export taxes, both countries may be better off if they both delegate to policymakers who maximize tax revenue rather than welfare. However, both countries delegating to policymakers who maximize tax revenue is not a Nash...
