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...

The Byrd amendment to US anti-dumping law distributes the revenue from anti-dumping duties imposed on foreign firms to the domestic firms that lodged the complaint of dumping. When the government sets its anti-dumping duty to maximise a welfare function that attaches greater weight to the...

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...

This paper analyses unilateral trade liberalisation in a Cournot duopoly model where the domestic and the foreign firm have different marginal costs. There are three results in the paper. Firstly, with linear demand, it is shown that the domestic country will lose as a result of unilateral free...

<link rid="b8">Freeman (2006</link>) suggested that auctioning immigration visas and redistributing the revenue to native residents in the host country would increase migration from low-income to high-income countries. The effect of the auctioning of immigration visas, in the Ricardian model from <link rid="b7">Findlay (1982</link>), on...

The analysis of collusion in infinitely repeated duopoly games has generally assumed that marginal cost is constant, but this note uses quadratic costs (linear marginal costs) to compare the sustainability of collusion under Bertrand and Cournot duopoly with differentiated products. It is shown...
