Shono and Kawaguchi (1999a, 1999b, 2000) present Spatial Equilibrium Model of international trade under tariff quota system with specific and ad valorem duties, and specify the equilibrium condition of the model as Linear Complementarity Problem (LCP). They also present several examples of the LCP and solve the example problems to show that the LCP has a solution. But they give no general mathematical proof of the existence of a solution to the LCP. In this paper, we give a general mathematical proof of the existence of a solution to the LCP, and we discuss efficient algorithm to solve the LCP on the basis of our computationa experience.
