We present a unified treatment of optimal trade policy for a small country. The well-known results for duopoly and competitive markets emerge as benchmark cases of our model. In addition, we show that changes in market structure have non-monotonic effects on optimal tariffs. Our results suggest...

It is shown that the equivalence of tariffs and quotas is not valid if one defines equivalence in terms of welfare. In a duopoly where a home and a foreign firm compete on a domestic market, an optimal quota leads to a lower welfare than an optimal tariff. Still, any import quantity can be...

Developing and Eastern European countries recently started opening their economies. We analyze how the opening to international trade can be accompanied by strategic trade policy if the resulting market structure is oligopolistic. We find that for reasonable parameter values, a tariff is the...

In a homogeneous-good duopoly game with a home and a foreign firm, which compete on prices, it has been shown that the optimal way to assist the domestic industry is by a production subsidy. The argument here is that the subsidy is used to keep potential competitive pressure on the foreign firm....
