In the course of the presently ongoing WTO negotiatioin round on agriculture several production sectors especially of those markets with a high protection level are submitted to a careful examination for futher liberalisation possibilities. The Japanese agricultural sector, which is still being highly protected by domestic support as well as by several border measures, is amongst those markets that are internationally highly criticised. Althoufgh Japan has successfully implemented its obligations according to the previous Uruguay Round Agreement there are still complicated protection measures, which impede a further market opening. The so-colled gate-price system of the Japanese pork market is amongst those protective measures, which were negotiated on in the Uruguay Round and have ever since proved to be an abstacle to an anhampered pork trade between Japan and its major pork exporters. However, acting as a variable levy it is difficult to integrate the gate-price into spatial equilibrium models. This paper prevents one possible method of introducing the gate-price to spatial equilibrium trade models by converting it into an as valorem tariff equivalent rate.
