摘要：Explicit modelling of tariff rate quotas (TRQs) is important in the current World TradeOrganization negotiations. In order to do such modelling with GTAP, extra data is requiredand extra equations must be added to the model. This paper provides tools for assistingmodellers to carry out explicit modelling of bilateral tariff rate quotas in GTAP usingGEMPACK.The paper describes how the extra data for sugar TRQ applications was obtained andreconciled with the standard GTAP data. Supplied with the paper is a TABLO Input fileTRQDATA.TAB which others can use for reconciling their TRQ data with the usual GTAPdata.Supplied with the paper is a module which can be added to the standard TABLO Input files forGTAP. This module contains the extra equations required to model TRQs.Detailed hands-on examples are supplied with the paper, as is a TRQ application relating toliberalization of TRQs on sugar imported into the USA. Readers of the paper can replicatethese applications.A windows interface TRQmate is supplied with the paper. This is a relatively general-purposeinterface which automates the steps in carrying out TRQ applications with GTAP andGEMPACK.If you wish to carry out your own bilateral TRQ applications with GTAP and GEMPACK, thetools supplied with this paper will make it relatively straightforward for you to do so once youhave collected the extra data you need.
