Introduction of Differential Tariff to Spatial Equilibrium Model of International Trade Under Tariff Quota System with Specific and Ad Valorem Duties : Example Study : The Case of Perfectly Competitive International Trad

Kano and Kaawguchi(2003) develop theoretical introcuntion of differentiate tariff to special equilibrium models of perfectly compentitive international trade under real tariff quota system with specific duties and ad valorem duties (Shono and Kawaguchi 1999a). But no example problem of the model is solved numerically. In this paper, example problems of Kano and Kawaguchi(2003) are solved numerically to show that we can get equilibrium solution of the model. Implications of this paper and problems to be soleved in the future are summarised in the last section of this paper
