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...

The result of Colombo and Labrecciosa [Colombo, Luca and Labrecciosa, Paola (2006). 'The suboptimality of optimal punishments in Cournot supergames', Economics Letters 90, pp. 116-121.] that optimal punishments are inferior to Nash-reversion trigger strategies with decreasing marginal costs is...

A Cournot duopoly model is used to explain the paradox that multilateral trade liberalisation has resulted in increases in both the volume of world trade and the amount of foreign direct investment (FDI).
